摘要:
The present invention relates to a method of manufacturing at least a part of a sports article, comprising the steps: (a.) determining a set of physical parameters of the sports article, the set comprising a first group and a second group; (b.) determining a set of constraints for the first group of the physical parameters, wherein the set of constraints is intended to achieve at least one objective function; (c.) determining an optimum for the at least one objective function, wherein the optimum is determined by optimizing the second group of physical parameters; and (d.) manufacturing the part of the sports article according to the set of constraints and the second group of optimal physical parameters.
技术问题语段:
The patent text is about the simulation and design process of modern sports articles, which involves a lot of complex calculations and parameters. This process is made even more difficult by the addition of 3D printing and robotic assembly, which adds even more degrees of freedom. The technical problem that the patent text addresses is the challenge of designing optimal sports articles by coating them with traction elements while considering the large number of parameters and the non-linear properties of materials used in additive manufacturing processes.
技术功效语段:
The patent text explains a method called finite element analysis (FEA) which is used to solve a variety of engineering problems. FEA breaks down a big problem into smaller parts and uses approximations to get a solution. This method is very accurate and can provide accurate results.
