Engineering Design Process

Engineering Models I1Course ObjectivesTo explore the application of algebra, trigonometry, and calculus to various engineering disciplines. To learn the fundamentals of programming and good programming practices and utilize these skills to solve numerical problems and create numerical algorithms.To develop good problem solving skills by applying problem solving strategies to a variety of engineering problems with MATLAB.To cultivate effective team-work and communication skills through lab work and a design project.

2Course StructureLecture:Meets once per week for 55 minutesBring your laptopsAttendance is required (5% of grade)Students are expected to view videos prior to attending lectureShort Blackboard quizzes at start of lectureRecitation:Meets once per week for two hoursBring your laptopsAttendance is requiredHomework assignments and recitation work from the previous week are due at the beginning of recitation3ExpectationsAttendance is required for both lecture and recitation.Students should prepare for lecture each week by viewing the videos prior to lecture and doing the suggested exercises.Students should prepare for recitation each week by reading through the lab prior to recitation and completing any required pre-work.Assignments must be turned in on time. Homework will not be accepted late and quizzes cannot be made up.Working with other students is encouraged. However, all assignments that you turn in must be your own work! All students turning in duplicate documents will receive a zero on the assignment including the student that actually completed the work.

Data Collection & Analysis

NASAs Orbiting Carbon Observatory (OCO-2): Due to launch next July. Will take 200,000 samples of the Earths atmosphere per day to track atmospheric levels of CO2 (73 million data points per year).http://oco.jpl.nasa.gov/ New I-35W bridge in MinneapolisOld bridge collapsed August 1, 2007 killing 13 people and injuring 145 others. The bridge has 500 Smart Bridge sensors. Some sensors record the bridge's response to vibration, corrosion and environmental conditions. Other sensors trigger an automated anti-icing system when wind, temperature and humidity reach certain levels. Others detect unauthorized activity on and around the bridge. http://minnesota.publicradio.org/display/web/2012/08/01/news/high-tech-new-i-35w-bridgeData Collection & AnalysisPillCam video capsule

An Israeli biomedical company, Given Imaging, has developed a minimally invasive tool for diagnosing diseases of the GI tract that substantially improves visual imaging of the small intestine. The capsule, which is swallowed by the patient, contains a tiny video camera that transmits 50,000 digital images from the GI tract to a receiver fitted in a belt around the patients body. All 50,000 images are downloaded to a PC for analysis.

23Problem SolvingExercise SolvingProblem is poorly defined all of the necessary information is not provided.The path to a solution is not obvious. Information must be gathered, questions must be asked, and new knowledge may be needed.Multiple solutions are possible and analysis is required to choose the optimal solution.Problem solving requires synthesis or integration of knowledge from several areasExercise is well-defined with all the needed information provided in the problem statement.All the background for solving the exercise has been provided (examples, appropriate formulas, ).There is one right answer.Solving an exercise typically only requires knowledge of the material being covered in class or closely related pre-requisite courses.Engineers Solve Problems not Exercises24Engineering EducationIn an engineering education, exercise solving is important because it builds technical competence in your field a necessary skill for effective problem solving in engineering. In an engineering education, problem solving is important because it requires integration of knowledge, self-directed learning, creativity, good analytical skills, effective communication, and an ability to work productively on a team.25DEFINE

Draw sketches, charts, or figures, write equations, and/or re-describe the problem.Take time to gather critical background information and data.Able to draw on and apply pertinent subject knowledge.Follow a systematic process, using a variety of tactics, to tackle the problem.Do not give up easily persevere when stuck willing to deal with ambiguity and able to cope with frustration or stress.Open to alternative viewpoints and opinions.Emphasize accuracy over speed. Check and re-check.
