we picked a more focused direction for you"

More idea exploration?Why waste time?!
“just tell us what the design problem is and we will do the detailed engineering.” "
there are many smart, well educated people in the world!
the mere formulation of a problem is far more often essential
than its solution Albert Einstein"
1879-1955, Nobel prize in physics"a relatively smart person"

went well? "Yes!"could every one of the presentations be improved? "Yes!"

3-ideas presentationTips!
stand with poster"avoid rocking"energetic"not forced"avoid memorizing"avoid filler words um, uh, basically, like…"interact with poster"but look at audience"have a clear ending"

responding to instructor
the least useful comment is __________!
feedback!
“good job”!
we received comments that were unfair!
we received conflicting advice!
![Page 11: ideas must be put to the test. that's why we make things, …web.mit.edu/2.009/www/lectures/9_sketchModels.pdf · 2011. 9. 27. · 2.009 Product Engineering Processes! otherwise they](https://reader035.fdocuments.in/reader035/viewer/2022071014/5fcca9aee1b4a3584531464c/html5/thumbnails/11.jpg)
and now a mini quiz! More estimation!
name on index card, 4 minutes"
i) what is energy and what are its units?"ii) what power is needed for a small bird to fly?!
iv) how much power can you output continuously for 30 minutes?!
iii) define mechanical horsepower.!

Sketch Model ReviewMeans… development of ideas into concepts!
more idea generation!
more research: customer needs/benchmarking(information officer session Thursday)!
sketch models/testing!
feasibility estimates!
![Page 16: ideas must be put to the test. that's why we make things, …web.mit.edu/2.009/www/lectures/9_sketchModels.pdf · 2011. 9. 27. · 2.009 Product Engineering Processes! otherwise they](https://reader035.fdocuments.in/reader035/viewer/2022071014/5fcca9aee1b4a3584531464c/html5/thumbnails/16.jpg)
And what is a sketch model?definition!Simple physical models made of soft, low cost, easy-to-work materials"
3D analog to sketching "
Made to learn and test!articulate an idea"understand product scale"explore user interaction issues"assess operational issues"establish common shared view"
![Page 17: ideas must be put to the test. that's why we make things, …web.mit.edu/2.009/www/lectures/9_sketchModels.pdf · 2011. 9. 27. · 2.009 Product Engineering Processes! otherwise they](https://reader035.fdocuments.in/reader035/viewer/2022071014/5fcca9aee1b4a3584531464c/html5/thumbnails/17.jpg)
What is NOT a sketch model?Anti-definition!
Simple physical models that have no purpose and are made of soft, low cost, easy-to-work materials"
