Final Presentation
of the Folding Three-Wheeler
May 17, 2007
Recap
• Remember our pink
wheelchair?
• Lots of feedback after last
presentation
• Looks significantly
heavier
• Trying to be too ambitious
• PCV allowed easier
sliding than steel would
• Concerns about denting
• Thumbscrews easy to lose
New Thoughts
• Refocused on most critical module, the third
wheel
• Considered all of our original ideas for this
mechanism
• Narrowed to top three: simple removal,
sliding, and folding
Simple Removal
Sliding
Folding
And then the
super hybrid was born….
Manufacturing
• Unfortunately we weren’t able to
manufacture anything by today
• We have all our materials and will have our
finished product next week
Thank you to everyone for your
feedback and support!
