ABSTRACT Environmental contamination is a problem that is challenging to resolve, as we are all aware. The issue of water pollution is one of the pollution issues that requires attention. As a result, the authorities have taken several actions, including establishing trash vessels. This vessel, however, cannot be used in confined spaces. The goal of this project is to create a new floating module that are not useful in places where diesel engines or electric motors are not permitted due to pollution or noise. The Floating Trash Collector Bicycle is a floating object that uses a conveyor to gather rubbish or waste and manpower to locomote the vessel. The Quality Function Deployment (QFD) method was used in the development of this module. Although, the Interceptor 004 and Mr. Trash Wheel are two examples of these trash collector devices that are often huge in size. The goal of this project is to create a smaller floating module with the same purpose as the Interceptor 004 and Mr. Trash Wheel, but with advantages in smaller bodies of water like ponds or lakes. xii CHAPTER 1: INTRODUCTION 1.1 INTRODUCTION The design of the floating trash collector bike is covered in this chapter along with the context of the research, its significance, its limitations, and its issue description. The marine pollution industry (MARPOL) was the inspiration for the floating trash collecting bike. The marine pollution industry (MARPOL) can apply this model design in many ways. Floating trash collector bike have been widely used for the purpose of cleaning up water bodies. This design of the floating trash collector bike can locomote the vessel by manpower pedalling. This vessel will be pedalled by a hand crank which is mesh up with a smaller gear that is connected to a shaft and a pulley. Another bigger gear is also mesh up with the second gear based on the figure given. For the arrow direction, the hand crank and big gear will manoeuvre in clockwise rotation to operate the propeller. While the smaller gear will manoeuvre in an anticlockwise rotation which operates the conveyor belt from the pulley. For the rudder system, the foot pedal is controlling the rudder by few pulleys, a wire attached to the tiller. When a person steps on the left leg forward, it will determine the motion of the vessel to the port. Same goes vice versa with the right leg. 1 1.2 RESEARCH BACKGROUND This project is to construct a combined vessel of a medium-sized trash collector and floating trash bike that can easily use in lakes and pond. Floating Trash Collector Bike is a trash collector project inspired by Mr. Waterwheel & Floating trash bike. The concept used in this project is the same as Mr. Waterwheel but instead of being powered by battery it will operate by pedalled manpower. Floating Trash Collector which is being pedalled by someone where the hand crank is mesh up with a smaller gear that is connected to a shaft and a pulley that can make the conveyor belt move. 1.3 PROBLEM STATEMENT The amount of plastic trash in our oceans is estimated to reach 5.25 trillion pieces. 4 billion microfibers per km2 live below the surface, while 269,000 tonnes float. 15% of our trash floats, 70% sinks into the ecosystem of the water, and 15% ends up on our beaches. Annually, 8.3 million tonnes of plastic are dumped into the ocean. Environmental issues are becoming more widespread these days. These issues are a result of developing activities including building homes, workplaces, and other commercial spaces. Numerous factors contribute to the environment's difficulties, including insufficient funding for environmental management and poor rubbish disposal practises. Garbage and waste from numerous sources that are dumped into rivers is a recurring environmental problem that is currently unresolved. Garbage can obstruct water flow, making it unclean and odorous. It can also frequently overflow and cause floods. 2 Floods are unavoidable occurrences that happen every rainy season in Malaysia. Figure 2 depicts the army evacuating citizens from Chaah town in Segamat, Johor, Malaysia during an extraordinary flood. Floods can spread several diseases that are brought on by rodents and other dangerous by products. When trash clogs the drainage systems of the river bodies, it causes creeks to overflow and causes flooding. Rainwater does not drain quickly enough, causing low-lying communities next to rivers and lakes to experience protracted floods. Figure: 1.1: Residents evacuation at Segamat, Johor, Malaysia Figure 1.1 from Kong et al. (2010)'s study on urban flooding illustrates that 28 % of respondents believe that poor drainage systems are to blame, 20% beli eve pollution is to blame, 18% say that managing urbanisation is to blame, 16 % said environmental factors, 11% said weather, and 7% said dam failure (K ong et al., 2010). 3 Figure 1.2: Data analysis people perspective of reason of flooding The study conducted by Thorndahl et al. corroborated this finding (2008). The report claims that inadequate drainage systems cause floods, and it lists seven reasons of urban flooding, three of which are connected to drainage systems (Thorndahl et al., 2008). Similar to this, Gallegos et al research indicates that dam breaking can cause urban floods (2009). The research of Kong et al., (2010) on the incorrect management of the environment as one of the causes of floods is supported by another claim made by Oguntala et al., (1982). (Akin et al., 1982). This demonstrates that inadequate drainage systems, dam failure, and poor environmental management are the primary causes of flooding. 1.4 RESEARCH OBJECTIVES There are three objectives to be outlined in the research which are: • Using the Quality Function Deployment (QFD) approach to create a garbage collector. To increase product quality, the Quality Function Deployment (QFD) approach is crucial. • To analyse the design using computer software to enhance it. The floating trash collector is intended to improve upon the current design in certain ways. This invention comes with a fresh system and a stylish design. The water surface area can benefit greatly from the implementation of this design model. • To create a vessel that can move beyond different ranges. 4 1.5 RESEARCH SCOPES The creation of trash collectors that can operate in constrained spaces and are reasonably priced for all parties will be the main goal of this project. This project's design phase utilized the Quality Function Deployment approach. This approach places the customer's needs first and foremost before starting any projects. Prior to moving on to this step, a product benchmarking must be completed, in which all currently available products and their specifications are listed, followed by a comparison of all of them. Next, the project also focused on the additional designs of the systems to operate the vessel and the software’s used to design the vessel. 1.6 LIMITATION OF STUDY The specification comparison research on other current design models is what this project's design is based on. The manufacture of the floating trash collector bike may take longer than the allotted semester weeks because of its somewhat sophisticated design. The creation of the solar paddling model and comparison of the requirements will be used to carry out this project. • Financial Aids The cost of the design This endeavour is crucial for creating the 3Dprinted model because it entails spending money on materials, printing, and transportation. Students at UniKL MIMET are given a budget of RM250 per participant. About RM300+ is needed to print the design into a 3D model. Additionally, the supplies required to complete this job are estimated to be worth at least RM 3000, which is more than our available budget. 5 • Expected Outcomes The key to improving our quality of life in the current period is innovation and improvement. This is because development and excellence cannot be attained without innovation. By conducting this research, it can encourage people to always think critically and come up with solutions that can make our lives easier. 6 CHAPTER 2: LITERATURE REVIEW 2.1 INTRODUCTION The purpose of the study is to consider the proposal and conduct an analysis of the current floating trash collector vessels. The chosen existing waste collection vessels have diverse designs but serve the same purpose. For the project study, these designs were assessed and studied to identify any differences, whether positive or negative. The information that can be obtained from the studied literature can be analysed to produce data for product benchmarking comparisons. From there, we may create the final design that satisfies user needs and addresses the problem. 2.2 FLOATING TRASH COLLECTORS Most Trash Collectors invented are solar panelled or operated by battery. With its large size as well as expensive capital, this has brought problems to clean on small areas and had to add a lot of manpower. There are lot of disadvantages that happen using the modern technology. Such as: Short Circuit Problems • Insufficient current due to drainage of battery during operation at certain period. Depending on the current capacity of the battery. Other than that, wires, relay, motor and etc must be waterproof so that it does not cause any circuit breakdown when operating the vessel in lake, calm rivers etc. Besides that, electrically operated trash collectors only have a specific range to clean water. Driven by Diesel Engines • Diesel engines incur high maintenance which may be very costly and time-consuming during maintenance. Apart from that, when dealing with diesel engines causes pollution. It can either be noise pollution, air 7 pollution (ANEX 6) or oil pollution (ANEX 1) which are under MARPOL Regulations. Not permitted in some countries • There is a country (India) where diesel engines or electric motors are not permitted due to pollution or noise. This may be a disadvantage for customer requirements and satisfaction. The purpose of this project is to design and develop a trash collector structure that can be used to reduce the main disadvantages mentioned above. The reason for the study was to build other items that have more advantages as well as being able to solve various problems. There are specific aspects of this project that allow it to function well. To guarantee the project's quality, the sort of material employed is also crucial. While the project's primary components must be up to date with emerging technologies. 2.3 WATERWHEEL TRASH COLLECTORS Floating waste is removed by Trash Wheel employing rotating forks that dip into and out of the water. The rubbish is then placed onto a conveyor belt and moved into a dumpster. On the Internet, the water wheel can be remotely managed. While cleaning the waterway. Additionally, it will assist the government in lowering the cash allocated to initiatives like cleaning up rivers and lakes. When compared to a coastal trash collector, trash is collected by a moving module and with the resistance of a conveyor belt to get the trash on the surface of the water, then sent to the garbage cage at the back of the vessel where the vessel is operated by technology that makes the personnel feel like they are playing with a remote-controlled car with a limited controllable area. Waterwheel trash collectors, on the other hand, are propelled by water wheels and solar cells and provide a larger range of space for the vessel to collect waste. Although our design is an improvement over the garbage wheel collector, it is not driven by solar energy. Instead, it will be manually powered by staff paddling. Despite being a development over the garbage wheel 8 collector, the personnel will physically turn a hand crank to power our design instead of solar energy. Additionally, Waterwheel Trash Collector will decrease the negative effects that water pollution has on plants, trees, the soil, and other natural resources on earth. 2.4 PREVIOUS FLOATING TRASH COLLECTORS 2.4.1 MR. TRASHWHEEL COLLECTOR Mr. Trash Wheel is propelled by the river's current, with solar panels acting as a backup source of energy when the current is weak. They drive a conveyor belt. Using rotating forks that dip in and out of the water to collect floating rubbish, Mr. rubbish Wheel transports the waste to a skip through a conveyor belt. On the Internet, the water wheel can be remotely managed. Usually, many company designed it in a portly size such as Mr. Trash Wheel. From this vessel we will use the idea of the waterwheel as our propeller and the conveyer belt to collect the trash. Figure 2.1: Mr. Trash Wheel 2.4.2 FLOATING TRASH BIKE The cycle seeks to increase the dissolved oxygen content of the water bodies while also cleaning the lake. The handle on the floating cycle can be used to control the propeller. The front of the device has a mesh 9 attachment that will catch floating trash and solid waste from the lake. The water will be stirred up by the paddle wheel at the back, aerating the body of water. PVC Pipes are used to with required buoyancy so the vessel could float on water. From this project, we will use their idea paddling idea but create an innovation to hand paddle the vessel so it could move and operate and less dangerous for the personnel compared to the figure given below. Figure 2.2: Floating Trash Bike 2.4.3 CATAGLOP VESSEL This kind of vessel's primary job is to gather floating solid and liquid garbage. The desire and necessity to clean up the waterways area led to the construction of the vessel. Users now have additional alternatives for how to use it to clear the aquatic environment of debris and waste. The recovery of hydrocarbons and macro waste, integrated wheels for one-person launching, an updated V hull for increased vessel speed and stability, and simplicity of transport on its road gauge trailer are some of its benefits. The Cataglop forces a stream of water through a mesh-lined tank where solid waste is filtered using a turbine pull mechanism. After then, the stream is split in half. The clean water is first 10 removed by the turbine. In a hydrocarbon separator, where the hydrocarbons are kept floating without emulsion, the oil- and hydrocarbon-contaminated surface water is subsequently sent. In order to increase the speed and stability of the vessel's movement and operation, we will be adopting a small variation of the V hull design in our project. Figure 2.3: Cataglop Vessel 2.5 MAIN FEATURES Floating Trash Collector Bike system has some key features where it is taken and reviewed from existing projects. The main features of the Floating Trash Collector Bike project are outdated but practical and efficient. These key features also help solve various problems and even the mission of the project is achieved: • Conveyor belt A chain conveyer belt is placed at the front of the trash collector. A light chain conveyer made of several links was designed. The links are made of PVC pipes. System was made to tilt the conveyer up or down. The conveyer points down while picking up the trash and points up while unloading the trash onto the trash bin. 11 • Rudder A rudder was placed at the rear to direct the garbage collector. The rudder is operated by the footrest through mechanical cables. The rudder of the garbage collector is placed outboard. The external rudder is attached to the tiller. • Pedal The garbage collector is pedalled by the operator by hand. The cycling movement is transferred to the propeller through a shaft and pulley. Conventional pedals should be used. • Seat An adjustable seat is provided behind the pedal. The operator can pedal the propeller and steer the footrest while seating comfortably. • PVC pipes The PVC pipes are made to assemble all the parts of the trash collector together so it could operate. They are chosen for the material of this vessel because it’s lightweight which will be able to float and operate above water. • Waterwheel The waterwheel are connected to and powered by the pedal. The propeller transfers power by converting the rotary movement into thrust. The propeller pushes backwards and helps manoeuvre the waterproof bearing connected to the conveyer belt. 12 CHAPTER 3: METHODOLOGY 3.1 INTRODUCTION All the approaches utilised to finish the project are discussed in this chapter. These techniques are incorporated into the design, research and calculating processes. Since the goal of this project is to plan the Gantt chart, design the floating vessel using the stages of design method, show the design process, pulley calculation, buoyancy stability, and load capacity are all heavily stressed. Materials utilised for designing must have qualities that can contribute to the project's success. 3.2 FLOW CHART To produce an innovative floating module that is beneficial in locations where diesel engines or electric motors are prohibited due to pollution or noise. The procedure and approach used to create the design project are covered in this chapter. Beginning with the identification of customer needs, benchmarking of the product, deployment of quality functional components, idea selection matrix, and design, drawing, assembly of design processes. Figure 9 shows the flow chart of the process. 13 Figure 3.1: Flow Chart of Final Year Project Figure 3.2: Flow Chart of Stages of Design 14 Figure 3.3: Flow chart of Design Process 3.3 PROJECT PLANNING (GANTT CHART) The term "Gantt chart" refers to time-based task visual representations. They represent crucial project information including task durations, overlapping activities, and accountability arrangements. When a project's various tasks are to be completed, a Gantt chart employs timeframes to indicate when they will. The relationships between the different jobs are explained by these timelines. The activities and advancement of a project are shown on gantt charts, which are useful. Gantt diagrams show how beginning work on one project depends on finishing another one first. This knowledge can help project managers better recognise problems and choose how to proceed. Since it guarantees that the project will be finished on time, the planning timetable is one of the most crucial elements of any project or activity. 15 3.4 STAGES OF DESIGN The project used the Quality Function Deployment (QFD) approach for the design phase, where in the construction of this project will proceed step-bystep till the final design. The product benchmarking, customer requirements, idea selection matrix, and final design are the steps that are intended. To proceed to the final design, all these processes must be completed. 3.4.1 PRODUCT BENCHMARKING Product benchmarking is a method where it collects all the existing products and then lists all the specs of the product. For this method, the selection of existing products must have the same function but different spec. Then, the specs are compared and evaluated for the next method. 3.4.2 QUALITY FUNCTIONAL DEPLOYMENT (QFD) Excellent performance Deployment is a targeted method for attentively hearing the customer's requirements and then successfully meeting their needs and expectations. To guarantee that client needs are addressed, this strategy is crucial. QFD (Quality Function Deployment) was the primary technique used to gain a general understanding of the most important design criteria for selecting the design designations for the project. QFD was a targeted process for attentively and effectively hearing the voice of the customer. a method and toolbox for effectively identifying and translating customer requirements into specific technical specifications and strategies to create goods that fully satisfy requirements. QFD is used to translate client requirements into quantifiable design objectives and to guide them from the assembly level to the sub-assembly, component, and engineering process levels. The QFD is concerned with the most important consumer need. This product can analyse the needs of the customer using this technique. 16 3.4.3 CONCEPT SELECTION MATRIX (CSM) The last method used to obtain the final plan is examined in this section. The concept determination grid is a typical example of a multi-rules dynamic that selects the best option from a list of options at the initial phases of item planning and improvement. A determined set of concepts that has been normalised supports an effective plan. Microsoft Excel uses this method to carry out this technique. The concept selection matrix is necessary. 10 planned floating trash collector bikes refer to the benchmark item and choose every component in QFD. 3.5 FINAL DESIGN This section discusses the benefits of the product used to improve reenactments and model plans. The product is essentially a free client where the student can use the assignment. The tool for creating the model is SolidWorks Educational Product. 3.5.1 SOFTWARE TOOL SOLIDWORKS is used by millions of engineers and designers at tens of thousands of companies. It is one of the most popular engineering and design programmes out there. Due to its extensive feature set and superior functionality, SOLIDWORKS is used by a variety of industries and professions worldwide. SOLIDWORKS is an effective tool for designers and engineers since it uses parametric design. The designer can then see how changes would affect surrounding parts or even the overall solution. For example, a larger component would affect the joint or hole it is attached to. This makes it quick and straightforward for designers to find and fix issues. 17 Figure 3.4: SOLIDWORKS Logo 3.6 PULLEY LENGTH CALCULATION The system of two pulleys connected by a conveyor belt is examined by this pulley calculator (also called a belt drive). It can be used to determine the pulley's RPM (revolutions per minute), as well as its diameter. 3.7 BUOYANCY CALCULATION A successful vessel design must have the ability to float in water as its primary characteristic. Buoyancy is the term for the physical force that keeps items like boats and other afloat in liquids. This section discusses on calculation is evaluated to ensure that the Floating Trash Collector can float on the water properly. Calculations on this test need to be made to prove this product can float perfectly. This calculation uses the buoyancy force calculation method. It guarantees that the vessel will float parallel to the water's surface, offering a more secure haven. Level flotation: Minimizes submersion of the personnel, lowering risk of hypothermia and drowning. 18 CHAPTER 4: RESULT AND DISCUSSION 4.1 INTRODUCTION This section relates to the outcome of this item, whether it was archived or failed. This chapter deals with the floating trash collector bike's final design, the drafting process, the final design's outcome after assembly, the calculation of the pulley and buoyancy, and discussion at the end. The goals of this project to create an innovative paddle design that includes a solar system support, engine, battery, and lamp for use in sport paddling are fully met. 4.2 PROJECT PLANNING (GANTT CHART) Figure 4.1: Gantt Chart (Part 1) 19 Figure 4.2: Gantt Chart (Part 2) Figure 4.3: Gantt Chart (Part 3) 20 The duration of this project is 92 days (about 3 months), starting from week 1 on Monday 20 March 2023 until when the title was suggested by the student on week 3 was approved by the supervisor, the co-supervisor, and the program coordinator. On week 4 was the start of our introduction where research was made on the project (going through articles/ journals), determining the objectives and project scope and make the Gantt chart. This was estimated to be done in 17 days until week 6. After that, decided to move on with the literature review were reviewed to do more research on the project and parts of the floating trash collectors and review previous projects and the designs. It took 14 days (week 8) to do this due to mid semester break and Raya celebration week. Then, proceeded with our methodology where Mdm. Fadhlina advised to use the Microsoft Excel to create the Product Benchmarking, Quality Function Deployment (QFD) and Concept Selection Matrix (CSM) so that it’s easier for us to decide on our final design. It took a month to settle the stages of design. During the stages of design process, there were a few meeting gatherings and expositions to assist in using some software’s that were not experienced. From 15th May 2023 until 21st May 2023 (Week 10 – Week 11) was the time duration of our 10 sketches in QFD. From there designs were eliminated step by step to determine our final design. In week 12, the design process was finalised, and 3D design had to be created and the software decided was SOLIDWORKS. In less than one week the design was finalised and we finished our report. In week 14, our hardcover report and logbook were handed to Supervisor. 21 4.3 STAGES OF DESIGN Product benchmarking is a method where it collects all the existing products and then lists all the specs of the product. For this method, the selection of existing products must have the same function but different spec. Then, the specs are compared and evaluated for the next method. 4.3.1 PRODUCT BENCHMARKING Product benchmarking Table 1 finding has shown there are five vessels that are compared side by side. The first floating vessel is the trash collecting bicycle which can be most likely used in sea water. There is a mesh attached in the front which will collect from the lake. It operates by the paddle wheel at the back will churn the water providing aeration to the water body and tit will vacuum any floating trash that goes inside the basket. It’s a dimension of 500mm tall x 500 mm wide X 1800 mm long. It can load 3.9kg of trash per day. In perspective view, it is inconvenient because it doesn’t have enough capacity to load the trash and there is no guarantee we can collect any trash since they used a basket to suck up any small floating trash. Moreover, it is very dangerous towards the personnel due to the stability of the vessel. Although, this project is diesel engine or electric motor free which is the motive of our final year project that wants to achieve. Secondly, there is the Waterwheel Garbage Collector which is most likely used in rivers or harbour front. This one activates as a trash interceptor, a vessel that removes trash from the Jones Falls River as it empties into the Inner Harbor. It has a dimension of 75ft long x 26 ft. wide x 16 ft. tall. It can load up from 11 to 19 tons per day. This design is approved with the concept of this project although the power solar energy must be terminated and replace it by using manpower to hand-pedal the bike crank. 22 23 Table 1: Product Benchmarking Thirdly, the next vessel is the Cataglop vessel where it is usually used for marina, harbours, and inland waterways. The turbine pumps away the clean water. Then, the surface water, polluted with oil and hydrocarbons. This vessel has a dimension of 30-40 metre long. It can load up to 1000L per day. Personally, it’s not a gravitated design to use except for the V hull design because it has more speed and stability which our project needs to make sure it operates smoothly. Fourthly, are floating drones which are most likely used in oceans & riverways. They vacuum and cleans plastic waste and biomass from water bodies using drone technology. This project has a dimension of 155 cm long x 107 cm wide x 45 cm tall. It can load about 160 litres per day. Unfortunately, this design is rejected due to the energy used which is by drone technology which defies the objective of this project. Finally, the last vessel compared in the table is the Interceptor 004. It is mostly used in pond & oceans. It is a remote monitoring dashboard, Automation Extraction Control, 4G data uplink to the cloud where personnel can control the vessel to collect trash like a remote operated automobile. The vessel has a dimension of 24m long x 5m wide x 8m tall. This vessel can load up to 55 tons per day of trash. Although, this vessel collects the most trash per day and it is the easiest way to clean up the trash, but it only has a specific range to clean waters which one of our main goals is to create a floating vessel that can go beyond different ranges. 24 Table 3: Customer Requirements Table 2: Technical Detail Since information of the main five vessels have been compared, the parts of this project have been evaluated in the table shown above. The technical details are separated into two groups which are the functional group and performances group. The functional group shows the featured parts used to build the floating trash collector which consists of Waste Bin, Waterwheel, Bike Handle, Waterproof Bearing, Waste Collector Stand, Conveyer Belt, Rudder, Stand, Rudder Post Extension, Helix Gear, Bike Crank Assembly, Crank Post, PVC Pipes, Paddle, and Chair while the performances group shows the purpose of the featured parts in the functional group. For example, the waste bin is used to store rubbish that is collected by the conveyer belt. The Waterwheel is used to move the vessel. The Bike Handle is used to steer the rudder. The Waterproof Bearing is used to move the conveyer belt upwards. The Waste Collector Stand is used for the surface of the waste collector. The conveyer belt is used to collect water debris, garbage & plastic. The rudder is used to control the movement of the project. The stand is used for the surface of the whole vessel. The rudder post 25 extension is used for to connect the rudder & crank. The helix gear is used to power transmitting gears. The Bike Crank Assembly is used to operate the propeller. The Crank Post is a stand & connection from the crank to the rudder. The PVC Pipes are used for the structure and floatation of the prototype. The pedal is used to be hand-pedalled by the operator. Finally, the chair is used for the operator’s comfort when pedalling the vessel. However, in the customer requirement segment there are 11 items that need to be required which consists of durability, eco-friendly, ergonomic, good function, robustness, efficiency, easyoperation, manoeuvrable, and stability. 4.3.1 QUALITY FUNCTIONAL DEPLOYMENT In every project, customer requirements are important in the quality function deployment. This is due to the design and introduction of the product are based on these needs. If these conditions are not satisfied, customers will almost certainly not purchase the product, and even if they did, repeat sales would not result. Like needs, but more concrete, actual, and reachable, are customer requirements. For the customer requirements, there is a calculation process that evaluated which will be attending to it shortly. In this project, the marks are evaluated from 1 (not important) – 5 (very important). For the durable, eco-friendly, ergonomic, safe to use, portable, good function, robustness, efficiency, and stability row, it is mentioned with a ranking of 5 points that is very important for this project. However, for the ecofriendly row, it is mentioned with a ranking of 4 points is important for this project compared to the other items mentioned above and the for the portable row consists ranking of 3 points which is moderately important. 26 The cumulating of all the points which consists of a total of 255 points. Then, evaluate the absolute weight of the technical details which are separated into two groups. The functional group shows the featured parts used to build the floating trash collector while the performances group shows the purpose of the featured parts in the functional group. Once evaluated the absolute weight of each part, then divide the total of each of the technical details with the total of the customer requirements and multiply by 100%. We will get to estimate the ranking order from the percentage ranges. 27 Table 4: Quality Function Deployment Method (QFD) 28 Table 5: Ranking Order Table 6: Percentage ranking range Table 5 & 6 shows the result of customer important in creating a product based on what customer asked. The result in this table will be used as a guideline to design Floating Trash Collector Bike. We have ranked the important materials in 6 different sections. In the 1st Ranking group, we have concluded that Waterproof Bearing is the main important materials with the highest percentage of 93%. 29 For the 2nd Ranking Group, we stated Waste Bin, Bike Handle, PVC Pipes and Paddle are the 2nd most important materials with a percentage of 80%, 85%, 81% and 84%. In the 3rd Ranking Group we have evaluated that the Waterwheel, Conveyer Belt, Rudder, Rudder Post Extension, Helix Gear and Bike Crank Assembly are suited in this category with a percentage of 76%, 77%, 76%, 73%, 76%, 73% and 71%. For the 4th Ranking Group, it’s evaluated that the Waste Collector Stand is suited in this category with the percentage of 69%. In the 5th Ranking group, it is evaluated that that the Crank Post is suited in this category with a percentage of 55%. Finally, for the 6th Ranking Group it is evaluated that the Chair is the least important materials used for this project with a percentage of 54%. 4.3.2 CONCEPT SELECTION MATRIX (CSM) This approach suggests three phases, which are Phase 1, Phase 2, and Phase 3. Phase 1 involves concept screening for an uncomfortable examination framework that broadens the range of concepts being evaluated. Phase 2 involves implementing the strategy so that it can improve and/or consolidate the concepts of estimated choice models and a higher rating scale. Finding the final plan to execute from phases 1 and 2 is the goal of phase 3. A choice framework that is used to evaluate, rank, and choose the greatest concept supports each stage. The customer precondition and client significance must be taken into consideration while scoring Phase 1. Since plans aren't always finalised at this point and sometimes still need to be carried out, the complete stamp shouldn't be applied to any one of them. Phase 2 will address the results of Phase 1, which involved more than ten stamps alone. 30 Phase 1's outcome was displayed below. “Yes”, signifies that the plan will be included in the next phase. While no signifies that the strategy won't be implemented in the subsequent stage. To be in the subsequent stage configuration can also combine to improve the strategy, like plans 1 and 2. Phase 2 will see the completion of 5 out of 10 plans at this time due to the evaluation of the project's actual requirements. Plans 1, 5, 6, 9 and 10 are chosen as the improve design of the floating trash collector bike in terms of stability and accountability. The next step is to develop a second plan that emphasises the plan's two out of one success stories and to assign a score. Simply write "yes" or "join" "yes" for the conclusion of stage 2, where "yes" and "consolidate" denote that the plan will be included in the final stage. Phase 3 is the last to determine which configuration is appropriate for the customer's requirements and which is crucial for the client. Only three plans from phase 2, including the best plan, will be picked. Plans 1, 5, 6, 9 and 10 will stick to their original designs. Since this is the final step before using the product, just say yes or no at this point. “Yes” signifies that the final plan is implied for outcome stage 3. 31 32 Table 7: Concept Selection Matrix – Design 1 to Design 5 (Phase 1) 33 Table 8: Concept Selection Matrix – Design 6 to Design 10 (Phase 1) 34 Table 9: Concept Selection Matrix (Phase 2) 35 Table 10: Concept Selection Matrix (Phase 3) 4.4 FINAL DESIGN The final design must be in three dimensions. SOLIDWORKS Educational Product was used to construct the 3D modelling for this design. The concept selection matrix approach was used to choose the design.

For assemble the parts to become of one complete body, the method that have being used is make the constrain to produce the contact between the flat surface of two components. With using this method, the component parts that have been constrained together will look neater and more organized. This is the last stage process to build the complete final design drawing. All this process is particularly important because each of element is related of each other. Figures below shows the part of have being constrained during the assembly process. Although, in this segment will show the exploded view of the parts. • First Part Figure 4.8: Floater 38 • Second Part Figure 4.9: Frame • Third Part Figure 4.10: The Pedal Mechanism & Components 39 • Fifth Part Figure 4.11: Tiller System • Sixth Part Figure 4.12: Trash Bin 40 • Seventh Part Figure 4.13: Compartments Assembled. 4.6 PULLEY CALCULATION This is conducted to calculate each pulley's diameter and RPM after the pulley system has been designed for the floating trash collector bike. n a system with pulleys like this, both the driver and the driven pulley have the same product of pulley diameter d and RPM n. It implies that: 4.6.1 PULLEY CALCULATION The driven pulley consists of a diameter of 150mm while the rotational speed that has been calculated and shown above is 30RPM while the driver pulley has a diameter of 50mm and a rotational speed of 90RPM. 41 D1 x n1 = D2 x n2 50mm x n1= 150mm x 30 RPM n2 = 150mm x 30 RPM/ 50mm n2 = 90 RPM Figure 4.14: Pulley system of the Conveyer belt As clarifying the matter, the drive pulley will rotate at 30 RPMs if the driven pulley rotates at 90 RPMs. This makes sense because the driven gear will rotate more slowly because it is larger which allows the conveyer belt to move slowly when picking up trash. 42 4.7 BUOYANCY CALCULATION This is conducted to ensure that the Floating Trash Collector can float on the water properly. Calculations on this test need to be made to prove this product can float perfectly. This calculation uses the buoyancy force calculation method. The answer is changed from Kilogram unit to unit Newton to obtain the load capacity that can be supported by the product. 4.7.1 THE WEIGHT OF MATERIALS: The process of this calculation is to identify the estimated weight of the components in the vessel based on hull load lines. The formula used to identify the weight of the components is called force of gravity. By gathering the weight of all the components will guarantee the estimated draft line of the vessel which accumulates to 273.092 N @ 27.83kg. Aluminium Alloy Weight of Aluminium Alloy =(0.3kg/m) Total aluminium profile used = 18m = 18m x 0.3 kg/m = 5.4 kg W= m x g = 5.4 kg x 9.81m/s² = 52.97 N PVC Pipes Weight of PVC Pipes = (0.4kg/m) Total PVC Pipes used = 13m = 13m x 0.4 kg/m = 5.2 kg W=mxg 43 = 5.2 kg x 9.81m/s² = 51.01 N Waterwheel Weight of Waterwheel = 3kg each Total Propeller used = 3kg x 2 = 6kg W=mxg = 6kg x 9.81m/s² = 58.86 N Trash bin Weight of Trash Bin = m x g = 5kg x 9.81m/s² = 49.05 N Crank & Pulley Mechanism Weight of Crank & Pulley Mechanism = m x g = 4kg x 9.81m/s² = 39.24 N Waterwheel Shaft Weight of Propeller Shaft = (4kg/m) Total Propeller Shaft used = 0.5m = 0.5m x 4 kg/m = 2 kg W=mxg 44 = 2 kg x 9.81m/s² = 19.62 N Waterwheel Weight of Water wheel = 15 kg W=mxg = 15 kg x 9.81m/s² = 19.62 N Conveyer Belt Weight of Crank & Pulley Mechanism = m x g = 0.2kg x 9.81m/s² = 1.962 N Gross weight of Vessel:1.962N + 19.62N + 39.62N + 58.86N + 51.01N + 52.97N + 49.05N = 273.092 N 45 4.7.2 BUOYANCY FORCE FOR PVC PIPE The process of this calculation is to identify the buoyancy force of the PVC Pipe and to determine the estimated trash load of the vessel can carry which is estimated about 202.2 kg including personnel. Based on figure 4.15, the gross weight is the capacity of the personnel on the vessel which weighs around 100kg at 6.4 cm. The deadweight is the capacity of the trash load at 75kg and personnel around 100kg on the vessel at 11.5cm. Radius of the PVC Pipe = 0.15 m Height of the PVC Pipes = 13 m Density of water, p = 1000kg/m³ Volume of PVC Pipe, V = 𝜋𝑟²ℎ = 0.23 m³ Gravity force = 9.81m/s² FB = pVg =1000kg/m³ x 0.23 m³ x 9.81m/s² = 2256.3 N 2256.3 N – 273.092 N = 1983.21 N Change to kg to identify the load line based on the figure below. M = W/g = 1983.21N / 9.81 m/s^2 = 202.2 kg 46 Figure 4.15: Hull Safe Load Lines In the figure, shows the buoyancy of the hull according to the load lines. The diameter of the pipe (height of the hull) is measured in 15 cm. 1-line equals to 1cm and 1cm represent 20kg. From the calculation, shows that there is additional amount the vessel could load which is lightweight (not including the personnel). 47 4.8 DISCUSSION 4.8.1 THE TANDEM PEDAL MECHANISM From figure 4.10, the crank pulley turns into forward direction when the personnel start to pedal, simultaneously the belt will drive the Waterwheel shaft which is attached with another pulley. Another propeller pulley will drive the Conveyor Twin Pulley. The smaller pulley that is attached to the bigger pulley will rotate in a forward motion leading the belting on the bigger pulley to drive the upper shaft pulley of the conveyor. The upper small idle conveyer pulley is attached to the gear which allows the conveyer to move in a clockwise direction while the idle gear which mesh with the upper conveyor shaft gear moves in an anti-clockwise direction allowing the conveyer to bring the trash move upwards and dump it inside the bin. 4.8.2 THE TILLER SYSTEM The tiller in figure 4.11, is running by using wire and pulley. To alter course of the vessel to the port, personnel must step on the left footrest, and it will control the rudder to the port. Instantly, the right footrest will move backwards, and it goes vice versa on the starboard side. This system is inspired by the theory of a small aircraft that controls the tiller. 48 CHAPTER 5: CONCLUSION 5.1 INTRODUCTION This chapter is the last part of this project. In this chapter, it discusses the conclusions that can be drawn in this project, summary of the project and is followed by a section of recommendations for improvements for this product. 5.2 CONCLUSION After sketching and putting everything together, this design has successfully produced the Floating Trash Collector Bike. This design can create a more advanced model by including compartments for items like a conveyer belt, crank, propeller, rudder, shafts, PVC pipes, and others. Using the entire compartment mentioned above in this section is a smart use of a hand-pedalled-wheel conveyer. When the model is totally constructed, the paddler will have a better and more comfortable experience. The study's methodology involved using hand calculations and an innovative design for a floating trash bike and a combination waterwheel waste collector. Since the device logically operates in water, we designed it to be waterproof. In order to perform for a long time, it should be corrosion-free. Then, as an improvement over the garbage wheel collector, our concept relies exclusively on human labour through hand-paddling by staff members rather than mechanical or solar power. By forgoing the purchase of pricey solar panels and fuel for a motored power system, this will save money. 49 5.3 SUMMARY This design floating trash collecting model can possibly collect rubbish estimate up to 100kg. The maximum weight of the personnel could weigh up to 100kg to hop on the vessel. This project design can a success one day and would be able to help minimize pollution in ponds, lakes, and rivers. As a result, we can draw the conclusion that our project is effective at saving money during the actual project's construction, can help preserve the environment by avoiding the use of fuel that emits harmful gases and doesn't require the use of battery capacity during operation, eliminates the problem of short circuit breakout, and can minimise the need for human labour to maintain our environment's cleanliness. 5.4 RECOMMENDATION It is proposed that further studies be conducted for future work and add crank pulley ratios to bigger pulleys so that personnel don’t burden themselves in using their strength to pedal control the vessel and gain more power to move the propeller. Another recommendation to consider is to find and alternative way to make the bike crank simultaneously operate the conveyer belt and control the rudder. Next, is to add in nets below the hull so it could gather up trash before allowing it to move the trash upwards and dump it to the bin. This is due to allowing trash from lower water levels to be extracted and compiled before lifting it from the conveyer belt to the bin. Besides that, redesign the rudder to a sophisticated design so the vessel could alter course in a smoother way. Finally, hope that one day this design could come to life and help the marine industry in limiting water pollution. 50 REFERENCES Abdullahi, M. G. (n.d.).
