Abstract: To solve the problems such as low efficiency of design knowledge acquisition and lack of effective expression and organization for product conceptual design,and to improve the ability of contradiction resolution in product design process,a product conceptual design method driven by patent knowledge graph and TRIZ was proposed.According to the design knowledge requirements of product conceptual design,combined with text compression and data enhancement methods,an entity relationship joint extraction model based on improved UIE (TC-UIE-senMixup) was established to accurately achieve extraction of entities and relationships in the absence of labeled samples.Based on a Function-Behaviour-Structure-Patent (FBSP) mapping relationship,a patent knowledge graph of the product was constructed.Then,the contradiction resolution method of TRIZ theory was used to eliminate the contradiction in conceptual design of products.Finally,the proposed method was applied to the shearer conceptual design process,and the optimization design of shearer cutting drum structure was taken as an example to verify the feasibility and effectiveness of the method.
