  • System and method for rim shape determination
    Patent number: 10733795
    Abstract: A system for determining rim shape includes a memory and a processor in communication with the memory. The processor is configured to receive one or more specifications for a rim. The processor is also configured to determine a rim depth for the rim based at least in part on the one or more specifications and a pareto front of rim shapes. The processor is also configured to determine a curvature control ratio and an endpoint tangency angle for the rim based at least in part on the rim depth. The processor is further configured to generate a rim shape for the rim based at least in part on the rim depth, the curvature control ratio, and the endpoint tangency angle.
