I want to stress that although my current wind-up wooden car is my final product for this project, I see the piece as another model working towards a greater design. As I said, throughout constructing and after completing the model, I saw a variety of elements I could change and improve. I pondered these changes and new ideas as I fell asleep last night and continue to do so now as I prepare to present my final model. While taking pictures of the model at various locations, I have assembled and dissembled the car numerous times. This process taught me more about the design and thus more things to consider when devising the next iteration. During my most recent photographing session, I asked my friend to sit on the car to show off how the side windows also served as handles and to put the concept into context. He too hesitantly sat on it but I reassured him although it would not propel him forward (which, I’m fairly confident in saying, is due to the band being too weak for the way I designed it to work), if he didn’t shake it, the car would support his weight. As he got more comfortable, he began lifting his feet. After a lifting his legs a couple times, the top piece fell out of place and hit his hand. Aside from feeling bad, I was reminded that the structure was not reliable the design should have more secure connections between faces. Better connections, I thought, could also aid in assembly as the stretched band between the front panel and rear axle makes adding the sides to the car challenging. In an effort to resolve these issues, I quickly sketched the following design on my iPad.
While I thought it would make it easier to put together and stronger, I now see how it could still be difficult to assemble. Locking in the front axle via two front pieces and having those and the remaining three sides secured in between the rubber-band-help top and bottom pieces would be more secure. Attaching the band between the front panel and rear axle, though, might be more difficult. This design does not touch on a more reliable or effective way of attaching the wheels. Currently, the wooden pegs work but they are not very attractive and I think a better means exists.
