COURSE OBJECTIVES
The goal of the course is to prepare engineers for the future challenges of design. Design is presented as the
integration of knowledge, skills, creativity, collaboration and hard work for the purpose of solving problems and
meeting needs. Engineering designers identify problems through research, acquire new knowledge through
exploration, create solutions using their analytical knowledge to model solution performance, refine solutions using
their analysis skills, test solutions using experiments and refine their knowledge and predictions using the results.
For the designer, the solution is never finished; it is always a work in progress awaiting another opportunity to
become even better. Design is taught within the framework of the modern engineering approach which requires
solutions that are high quality, innovative, low cost, and done quickly.
The objectives of the course are:
1. Nurture student capacity in methods of problem solving while highlighting the importance of creativity in
developing innovative solutions.
2. Build skills of identifying customer need, design goals, design objectives and translating these to specifications
for the design.
3. Exercise and improve important design skills of visualization, calculation, experimentation, and modeling.
4. Build skills in organizing people and ideas for successful design. These include skills in teamwork, project
management, verbal and written communication, and documentation.
These objectives are achieved through a combination of design exercises, presentations, design testing, and scale
model design and build.

Introduction to Engineering Design
INTRODUCTION
Design is the essence of the practice of engineering and is a fundamental requirement in the academic preparation of
an engineer. As stated earlier, engineering design is both problem definition and problem solving. For professional
designers, design is consuming because it draws on all the knowledge and skills the person has. As such, those with
skills and experience in design find that the same skill set can be applied in many areas besides engineering. Design
is also key to a company's ability to compete. A company with a superior design process will have: shorter time to
market, lower cost, better match of products to customer wants, and higher quality and performance.
The focus of this course will be the design process. The design process provides a structure in which the various
phases of design occur in a logical and efficient sequence in order to arrive at the most successful outcome. This
course will present the best of traditional design practices as well as several modern design tools. Seven phases of
design will be presented and experienced: (1) Recognition of the Need, (2) Creation of the Design Requirements, (3)
Conceptual Design, (4) Concept Development, Testing, and Embodiment, (5) Detailed Design, (6) Bench Testing of
Subsystems, and (7) Scale Model Design and Integration. While the description of design makes it appear as a
formula that one just applies, design requires creativity by the engineer. Creativity methods will be presented and
creativity encouraged in the course.
In engineering, the design process is not done in isolation but is done in collaboration with engineering colleagues
and suppliers of parts and materials. During design, the engineer addresses the needs and wants of the customer,
decides on the needed functions and features, collaborates with other engineers and designers on design decisions,
considers the costs and ease of manufacture, and conforms to regulatory and marketplace standards. For a significant
portion of this course, the student works as a contributing member of a design team with other engineering students.
The design team will be responsible for the full design of a response to the semester project challenge. The
individual student will contribute to the team performance through independent design work that meets the
requirements set by the team and the project assignment. The student’s work must be compatible with the work of
other team members and be integrated into the overall project vision of the team. Faculty will mentor each student in
this effort. Industry has identified teamwork as one of the more important characteristics of a successful engineer.
As a consequence, successful teamwork has a major role in satisfactory completion of this course. Team building
exercises and frequent meetings with a supervising faculty member are utilized to promote teamwork.
The best way to improve design skills is to apply them frequently. A series of design assignments are used in the
course which require the application of engineering fundamentals which have been already learned. To supplement
existing course experience, lectures are presented on several key technologies which can be incorporated into the
design. However, there will be many instances when the student will encounter topics and problems that have not
been covered in previous courses or lectures. In this situation, the student will be responsible for researching and
developing the necessary knowledge for solving a problem. Sources of this knowledge can involve using the library,
technical references, handbooks, or equipment catalogues, as well as consultations with others such as experts and
potential end-product users.
COURSE ORGANIZATION
The instructional aspects of the course include lecture, design sessions, professional development class, and studio
meetings in which students meet with the supervising faculty.
Lecture and Design Sessions (Monday and Thursday at 10am in JEC 5119). This course includes lectures.
Topics covered include the overall design process and the design tools which are used during the semester. After the
lecture, students will meet in design /studio sessions. These sessions expand on the material presented in lecture,
provide hands-on application of lecture material, provide a time for team activities on the term project, and provide a
forum for individual and team presentations on design work.
Professional Development (Wednesday at 4pm in DCC 308). The Professional Development segment of the
course meets weekly for 1.5 hours. This segment is taught by faculty and staff of the Archer Center for Student
Page 2
Introduction to Engineering Design
Leadership Development. A separate syllabus is provided for this segment. To receive an A for the course, A
quality work is required on this material. Poor performance in this course segment may require retaking the
Professional Development course before graduation.
Design Teams. The class will be split up into design teams. In general, design teams will be multidiscipline.
Within teams, sub teams are expected to be formed which will be assigned by the team to functional areas. The
team will take the problem from concept development to detailed design to bench test of design to scale model
embodiment. The individual and team assignments provide the steps necessary to design and test an innovative
design. The faculty advisor assigned to each team will act as a coach, cheerleader and consultant to the team. In
addition, the faculty advisor will closely mentor each student on their design effort and contribution to the team
design and test activity. Depending on the engineering discipline mix of a class, the team structure may be altered to
small specialty teams who are responsible for a stated functional module. The module must be plug_and_play with
the modules of other teams in the class.
Design Studio Meeting. Student design teams will assemble for these time periods and work in the presence of
supervising faculty on their design project. During the design phase, these studio sessions will focus on the design
and specification of the assigned artifact. During the bench test phase, these sessions will concentrate on testing and
demonstrating design feasibility
These sessions may also include formal meetings between the design team, individual students, and the faculty
advisor. The faculty member will work with the team on their design and help guide the team in the design process.
Team members should come to meetings prepared to discuss their design work and assignments. On a day to day
basis, the faculty advisor may assign specific tasks to be completed by the team or individual team members.
COURSE SCHEDULE, REQUIREMENTS AND GRADING
Design Notebooks. Each student must maintain a design notebook. This notebook required is the brown lab
notebook (National No. 43-648) available at the bookstore. The notebook must be organized following the outline
provided in the course Readings. The importance of this notebook cannot be overstated. It is the basis on which
your contribution to the design process of your team is evaluated. Everything that you do in connection with this
course and with your design must be entered in the design notebook. The material in the design notebook must
support the design decisions you and your team make. For example, if a power supply is part of your design project
and you are going to purchase it, the design notebook must have entries for determining the voltage and amperage
requirements of the power supply. These requirements are calculated as the sum of the load demands of the electrical
and electronic components in the design. Your notebook must list the components or subsystems, list the voltage
requirement of each, list the current requirements of each, sum the loads by voltage level, find the total load, and
provide for a safety margin of supply. Only when this is done can a power supply be selected. The notebook should
be brought to all scheduled meetings and class periods. It will be collected and graded many times during the
semester. An excellent notebook is required to receive an A in the course. An A notebook has:
• Fully documented research notes including dates and source references for both the individual phase of the
design assignment and the team phase. These research notes should abstract pertinent information from the raw
documents found and not just present the raw documents.
• Up to date time sheets listing how time was spent and current totals.
• Well documented design activity work including problem finding and resolution in conformance with the
guidelines presented in the course notes.
• Quantitative design development work supporting design decisions.
• Accurate and complete meeting notes which identify meeting time, date, attendees, discussion summary,
decision summaries, and items required of you from the meeting.
• Stated sources for work recorded in your notebook that is not your original work. For example, if you copy by
hand a sketch from another person, that person must be credited as the source of the work.

Introduction to Engineering Design
Your work on design activities includes individual design assignment work and on your performance as a member of
your design team. Your team performance grade is based on the substantive nature of your design project, how well
you and your team follow the design process outlined in class, how well the design choices are backed up with
engineering judgment and calculations, how well the team communicates the design in both presentations and written
reports, how well the team follows a project schedule with continuous and steady progress towards project
completion, and how well the team functions together including delegation of tasks and mutual assistance.
While grading of design activities will generally follow the percentage contribution presented below, students who
do not make verifiable and significant contributions to team activities will receive a lower grade for the team portion
based on their contribution to the team project. A non - contributing team member will receive a much lower
grade for the course than their teammates.

Requirements, Achievement of Design Goals and Design Innovativeness
The grade assigned is based upon performance and not on how much time spent by the student. Design is both
exacting and demanding. Outstanding work may contribute to the final grade above the maximum stated for a grade
category.
COURSE CONDUCT
We have chosen to operate this course with a different set of rules of conduct than a normal lecture course. In this
course you will be treated as an engineer employed by the company IED. You will be expected to behave in a
professional manner. All class lectures and sessions are company scheduled meetings. The instructors, as the
company management, expect you to attend, be on time, and to participate in all meetings (lectures, design sessions
and team meetings). If you cannot attend a meeting, we expect early notice not late notice.
STUDENT CONDUCT AND COMMITMENT
Each student should average 8+ hours per week outside of class on this course. This time should be spent on the
course every week. You will not be able to "read up' on the notes, or "cram" later in the semester to make up for lost
time. Delay in your work will impact the team and the project and has serious consequences for all. Keep track of
the hours you spend on this course, and record these in your design notebook.
Assignments for which the individual will receive a grade for their work must be the sole work of the individual
student. Collaboration, copying, "working together", plagiarism and falsification on individual assignments are not
tolerated. This applies to CAD work as well. Quotes and fair use of material produced by others is permitted
provided that this material is clearly marked in the assignment submission and complete reference information is
provided for material source. See the Student Handbook section on Academic Dishonesty for further information
on student responsibility for assigned work. If a student is found to have violated academic dishonesty standards,
the student will be assigned the grade F for the course and the case will be forwarded to Student Affairs for further
action. The student can appeal the finding to the instructors of the course in writing and the appeal will be
considered by the instructors of the course.
