Our object for our senior design class is to select a non-trivial design and analysis problem. It must relate to an existing physical product consisting of multiple compopnents. We must develop a functional model of the product and supporting behavior models of one of the key components. From there, we must recommend design changes to the existing model.

CAD anaylsis will be used, it can't be easy hand calculations.

I was wondering if you guys could say whether my ideas so far are any good, or if you have any that come to mind you could throw in. I'm sorry again to come to all of you, just thought this would be a good resource to use.

So far we have:

A Printer
Rolling Chair
Scooter/Motor Scooter
Roller blades (maybe allow pivot latterally for goalies)
