ELISABETH GAGNON
The team and I were tasked at designing a toy car that was propelled using a small indoor fan. As team lead, I was responsible for dividing tasks and managing the Gantt Chart, running team meetings, and performing the final review on all deliverables.
​
I designed the drive train and the propeller of the car on SolidWorks, shown on the left.
Initially, the propeller was to be attached using a belt to the rear wheels, but after prototyping, the design did not work. The blades of the propeller were then made with varying widths and pitches to determine if the propeller being spun alone would be enough to drive the car, and tests were run using a full factorial design of experiment. The car was 3D printed using minimal infill and PLA to try to maintain as light of a weight as possible. This design prooved feasible.
​
In addition to the design, I conducted a hypothetical design FMEA, a latitude development of the pitch of the blades, and also a tolerance analysis of the 3D printed parts. The resulting design was able to travel 8 metres, one of the top distances of the class, and received a letter grade of an A.
