[Abstract]:As the early stage of the product development cycle, conceptual design can best reflect the high-efficiency innovation of the product. The essence of innovation is to provide designers with ideal product design schemes. The product innovation process model based on the integration of Triz (invention problem solving theory) and bionic technology can better drive product conceptual design innovation. This paper mainly studies the conflict problem solving, the creation of innovative scheme, the synthesis and evaluation of original understanding scheme. The main research contents include: 1) the general process of Triz conflict resolution and the application of coupling bionic technology are explored, and a conflict resolution process model based on Triz conflict solution method and coupled bionic technology is established. At the same time, the visual operation of Triz conflict problem solving module based on the principle of biological function innovation is realized by using Matlab software. The conflict problem solving process model can effectively improve the efficiency of product innovation design. Through expounding the biological function model, the method of establishing the product organism function model is put forward. Based on the analysis of the relationship between functional evolution and technological evolution, the correlation matrix between them is established. Three patent curves are fitted by computer, and product technology maturity prediction is completed. Through analyzing the principle of ant colony algorithm, ant colony algorithm is applied to project synthesis and evaluation. The optimal product morphology matrix was optimized by Matlab software, and the ideal product principle scheme was obtained. Finally, the conflict problem solving module was applied to the engineering design of the blade of axial fan. Based on the analysis of the conflict of axial fan system, the bionic model of solving the conflict problem is obtained by using the software, and then the bionic coupling element structure of the blade of axial fan is extracted by biological coupling element analysis. The bionic coupling model of blade structure was established. Finally, fluent software is used to simulate the blade prototype and its flow and noise. The results show that the mass flow rate of the blade bionic coupling model is increased by 6% and the system noise value is reduced by 7.8%) the overall structure model of the new ultraviolet oil fume purifier system is established by using the above research results. The system of ultraviolet oil fume purifier is improved in smoke collecting cover, oil pipe, fan and so on. An engineering example verifies the applicability and efficiency of the proposed scheme synthesis and evaluation method based on ant colony algorithm, which is based on the generation mechanism of innovative schemes based on biological functional evolution and technological evolution. The research will provide some reference for the application and research of product innovation design method.
