12. ME2110 Design Competition • Design, build, test and compete with your machine • 5wks, $200 • Design Objectives released 09/16/2008 @ 8:05am • Competition commences 11/14/2008 @ 5:00pm

14. Do’s act professionally follow instructions be in class & studio on time use the tools that are presented read the book give professional presentations follow procedures (safety) clean-up in studio report damaged equipment Don’t’s miss class close your minds to the alternatives sleep in class bring food into studio leave a mess in studio. Pointers for Success

15. Attendance • You must attend all studios • Missing a studio results in a 0 for that studio grade • Make arrangements to attend another studio section • No way to make up a missed studio the next week • You must attend all lectures • Missing a lecture results in you being a loser for the day • Most of your work is done as part of a team. • Missing lecture requires your teammates to educate you. • That is not their job. • There are only 16 lectures.

16. Reality Check • This course is about • problem solving • considering alternatives • organization • writing • presenting • getting a taste of the real world • Professionalism • projects • reports • attendance • deadlines

19. Characteristics of Design • Multi-stage process • Large quantities of information • Many supporting design tools - analysis, optimization, simulation, etc. • Uncertain path to solution (Not just 1 solution) • Alternatives, revisions, versions, updates… • Iterative and cyclic • Teamwork - interactions between engineers & management • Multidisciplinary

20. Science and Engineering • Scientific Method • Science is theory corrected by experiment • Predicts the world • Engineering Method • Application of scientific principles to solve problems • The ordered sequence of steps used in engineering problem solving • Incorporates the use of • heuristics • logical, ordered, and systematic procedure • Changes the World

21. Design  Problem Solving • Analysis • What needs to be done • What do current products do • What are the necessary functions • Develop Alternatives • Many, many alternatives • Decision Making • Picking the Best Among Alternatives • Information Processing • Sketches to CAD Drawings • Drawings to Parts • Parts to Assembly

22. Design  Problem Solving Pasta Structure • Analysis • Turn pasta & tape into a stiff structure • Support a golf ball • Alternatives • Long beam, Truss structure • Tape stringers, etc • Decision Making • Most successful in round 1 • Coolest looking • Information Processing • Turn sketches into a real structure

23. Information in Design • Receive • TV/Cellphone/Ipod • Websites • Management • Journals • Colleagues • Students • Process • Analysis • Synthesis • Transmit • Drawings • Documents • Presentations (Design Reviews)

24. Information in Design Pasta Structure • Receive • Studio Handout • Instructor, TA • Teammates • Process • Performance specifications • Time requirements • Brainstorming ideas • Transmit • Sketches • Prototypes of sections • Report

25. Questions to Continually Ask When Designing • Where can I sell my product? • What products do my customers need? • How can I improve my product? • What customer needs are not being met? • When will my product become obsolete or inappropriate? • How are changes in technology affecting the marketplace?

26. Building Machines • How can our product be made? • What manufacturing processes can/must be used? • How can we make the product for less? • Can we use less expensive material or processes? • Can we simplify the design? (cycle back to design) • How long will it take to make our product? • Will we make it to market on time? • Will we make it in time for the ME2110 contest on November 20?
