This project is for an 11 year old kid, with Cerebral Palsy, play basketball with his friends and classmates in school.
The goal for this project is to design an arcade style basketball game. The game needs to be able to be played while in a wheelchair.
Basketball Game with foldable joint and wheels.
With this design there is a joint in the middle of the ramp that allows the bottom half fold up to the top into a concise rectangle which is easy to store. It also has wheels to be easily maneuvered. Space in front to let slide under making it easy to grab the ball.
These are all of the parts we need for our design. This includes PVC piping with connections, backboard made out of acrylic or polycarbonate plastic, rim, mesh retrieval netting, and side netting. The side netting and mesh netting are viewed as solid but will not be solid in person. Each design is scaled the same with accurate diameters and lengths.
For our first analysis, we wanted to simulate a point load onto the backboard. We used an acrylic material for it, and gave it a force of 1000N which is equivalent to a pro athlete throwing a ball. Reviewing the stress analysis, it is shown that the stress is nowhere close to the yield strength of the material. This model is shown with multiple point loads simulating a basketball hitting at many different points on the backboard.
For our third analysis we chose to simulate the weight of the basketball game on one of the base joints. We used a weight of 50lbs pushing down on the base. When scaled correctly, the stress on the base is manageable compared to the strength of the PVC pipe or even better if Aluminum piping was used.
