Returned to Covidien in 2009 as a Product Development Engineer Covidien Corporate Overview Covidien is… A global medical device and pharmaceutical manufacturing company with over $11 Billion in annual revenue Well positioned with a diverse portfolio of products and technologies in attractive franchises A company with a history of quality and innovation Highly efficient and productive, producing strong margins and cash flow A leading player across our portfolio What does Covidien mean? “Co,” from the Latin word for together “Vi,” from the Latin word for life Covidien is a unique name in our space within the healthcare industry – and it is designed to stand out from our competitors An ongoing partnership in the lifesaving work of medical professionals, creating far-reaching benefits for improved patient care What is the significance of the Covidien brand icon? Two bracketed "C's," representing Covidien's core values of Compassion and Collaboration Visually embodies support and integration The two “C’s” of Compassion and Collaboration Our Mission and Vision Our Mission Create and deliver innovative healthcare solutions, developed in ethical collaboration with medical professionals, which enhance the quality of life for patients and improve outcomes for our customers and our shareholders. Our Vision Deliver unmatched value to our customers by providing solutions that improve patient outcomes and healthcare delivery through clinically relevant and economically valuable innovation. Strong Line-Up of Well Recognized Brands Engineer in Residence Program This program is designed to send one to two Covidien engineer(s) to UCONN per week throughout the academic year. This engineer will provide senior design project support. Align senior design project syllabus with engineer skills so proper help is provided throughout the various project stages. First semester we will be at UCONN on Wednesdays. Present from 12:00-1:00 Office hours from 1:00-4:00 Extra credit available for participation. Disclaimer: Although we are all professional engineers our expertise tends to be in areas that we work in consistently. We do not know everything, but promise to help as much as possible and point you in the right direction if we don’t know. Engineer in Residence Program Topics Creativity Tools and Concept Selection Product Development Process/FDA for Medical Devices Rapid Prototyping/Machining: Methods and Design Guidelines CAD Basics How to Read Engineering Drawings How to Create Engineering Drawings Design for Manufacturing/ Design for Assembly Concept Creation and Selection Why do we need to learn about creativity? Thomas Edison and the light bulb filament: "I have not failed 10,000 times. I have successfully found 10,000 ways that will not work." Do you think this trial and error approach would be acceptable in the business world? We need to be innovative, but at the same time efficient Must have tools at our disposal that help us: Remove our bias Solution Space for Solver S Knowledge Boundary Think outside the box Bring novel ideas Be more efficient S P S S Real Boundary Constraints Presumptions Boundary Problem Solving Steps 4-STEP PROBLEM SOLVING GENERIC PROBLEM GENERIC SOLUTION ABSTRACTION ANALOGIC THOUGHT SPECIFIC PROBLEM SOLUTION BIAS 2-STEP PROBLEM SOLVING DRIVEN BY AUTOMATIC INTELLECTUAL RESPONSE Some simple creativity tools… Process Mapping Brain Writing Process Mapping Should describe: Major activities/tasks Sub-processes Process boundaries Input variables (X’s) Output variables (Y’s) Can help determine proper scope of project Shows unexpected complexity, problem areas, redundancy, unnecessary loops, and where simplification may be possible Great for laying out functions of a device, steps of a test method, etc. As more information becomes available, the map can be updated to verify the scope is controlled and correct for the design objectives Needs to be routinely updated Process Mapping Symbols Start, Stop A path (flow) from one step to another A step in a process A decision or multiple choice Storage or inventory Delay Process Map Example Clip Applier Squeeze Triggers Actuate handle link Translate Drive Channel Rotate Drive Link Translate Ratchet Plate Cam over jaws Rotate Driven Link Translate Pusher Rotate Pawls Yes Full handle squeeze? Push clip into jaws Form clip Partially formed clip Brain Writing (6-3-5) An alternative to traditional brainstorming Ideas are written instead of spoken Encourages building on others’ ideas Good for introverted personalities Brain Writing (6-3-5) 1. Everyone gets a brain writing form 2. Write 3 ideas across the top row 3. Allow fixed time intervals (5 minutes) 4. Rotate forms through group 5. Review ideas of previous person 6. Either expand on previous person’s idea (use arrows to show the flow) or write new ideas 7. Problem Statement Pass 1 Idea A Idea B Idea C A+B Idea D Mod C 2 B Mod A+D 3 Two sided for 6-3-5 Keep passing sheet until all participants have received each sheet 6-3-5: 6 participants, 3 ideas/pass, 5 min/pass Other methods to look into… TRIZ- Theory of Inventive Problem Solving A problem-solving algorithm developed by a Soviet inventor based on extensive research of global patent history 1. Problems and solutions repeat across industry and science 2. Patterns of technical evolution also repeat across industry and science 3. Innovations used scientific effects outside of the field in which they were developed http://en.wikipedia.org/wiki/File:TRIZway.jpg TRIZ Continued (www.triz40.com) Basic principle that inventive problems stem from contradictions such as, “I need a longer instrument shaft, but need to minimize its weight.” Improving Feature Worsening Feature Concept Selection: Pugh Matrix Developed by Stuart Pugh Used to compare alternative design concepts Comparisons based upon design requirements Results can be single or reduced number of concepts Pugh Matrix Steps for Application 1. Determine the design requirements 2. Identify competing designs with a small phrase or picture 3. Create a matrix with 4. 1. Requirements on left 2. Design concepts on the top Establish a team mutual understanding 1. All requirements 2. All design concepts 5. Weight the design requirements on a 1, 3, 9 scale if necessary 6. Rate each design’s ability to meet the requirements 1. Rank 1-3 (3=best, 1=worst) 7. Multiple weights by rating and sum each column to determine superior design 8. Evaluate each concept for “hybrid potential” Example Clip Feeding Pugh Matrix Weight (1, 3, 9) Design Options Evaluation Criteria Design 2 Design 4 Const. Force Spring Walking Beam Rank 1-3 (3= best, 1 = worst) Clip Tolerance Sensitivity 6 2 2 3 2 2 9 3 2 6 3 2 3 2 2 Robustness/Performance 9 2 2 Design for Assembly 3 3 2 Design for Manuf. 3 3 2 Overall Size 3 9 2 3 3 3 138 120 Complexity of Timing Mechanism Cost Tolerance Sensitivity of Mechanism Part Count Clip Stability Total Score Conclusions Concept creation tools help eliminate bias and provide a systematic approach to innovation Process mapping, brain writing, and TRIZ are just a few of the many tools available Once concepts are created, a Pugh matrix can help rank concepts to determine the best solution or hybrid solution Any questions?
