Extensible Innovation Design of Globoidal Cam Deceleration Mechanism Based on Knowledge

In order to increase the innovation and design efficiency of deceleration mechanism design, a knowledge-based product extension innovative design method was proposed. Extracting the characteristic knowledge of the product, constructing the knowledge model of the product, and combining the matter-element thought of the extension theory, transforming the knowledge model of the product into the extension matter-element model. Resolving the contradictions encountered in the product design process is realized through matter-element transformation. Using the correlation function in the extension theory, the correlation degree between the product design feature parameters and the corresponding design parameters in the existing product design knowledge base was calculated, and the design feature parameters with high correlation degree are selected to improve the efficiency of product design, extension design was used to improve the innovation of products, and the knowledge solving process of product design was given. Finally, a globoidal cam deceleration mechanism was taken as an example for verification.
