The work aims to propose the innovative design research of smart crib patent avoidance based on Analytic Hierarchy Process (AHP) and Theory of the Solution of Inventive Problems (TRIZ) to solve the problems of single functional requirements, unreasonable design structure and weak practicality of smart crib products in China. First of all, the product opportunity gap of smart cribs was analyzed and summarized through the research classification of existing crib products and the market research of target users. Secondly, the AHP method was used to evaluate the user demand weight level, convert the demand weight items into technical demand points, and at the same time consult in the patent search database to analyze the target patents related to the technical demand points. Finally, the TRIZ theory was used to analyze the contradiction problems in the target patent, and these problems were transformed into corresponding technologies, forming a contradiction matrix, and then solving the contradictions through the invention principle. The relevant principles of the design application were mainly the extraction principle, the principle of spatial dimensionality change, the principle of mechanical system substitution and the principle of pneumatic and hydraulic structure. Combined with Rhino and other three-dimensional modeling software, the concept design scheme of intelligent crib products was output. This study mainly combines AHP analysis method and TRIZ theory to carry out the innovative design of patent avoidance, realize the objective grasp of the demand points of the baby-rearing population, complete the innovative design of patent avoidance of smart crib products, and verify the scientificity and accuracy of the combined use of AHP-TRIZ theory.
