14. © GIT Pointers for Success 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.

15. © GIT 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 1.Most of your work is done as part of a team. 2.Missing lecture requires your teammates to educate you. 3.That is not their job. 4.There are only 16 lectures.

16. © GIT 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. © GIT 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. © GIT 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. © GIT 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. © GIT 22 Design  Problem Solving 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 Pasta Structure

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

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

25. © GIT 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. © GIT 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?
