Research And Application Of Variant Design Based On TRIZ Evolutionary Theory

With the integration of the global economy and the development of science and technology,competition among enterprises has become increasingly fierce.Traditional design products have long development cycles,high production costs,and unpredictable market adaptability.The contradiction between the short market cycle of the product and the long development cycle is critical to the development of the enterprise.The enterprise must adapt to the rapidly changing market demand and shorten the delivery period of the product.Variant design maximizes existing resource utilization,shortens design cycles,and quickly iterates new products.The variant design method is a common design method for modern enterprise production process.This topic combines TRIZ evolution theory,morphology matrix,PUGH matrix and case-based reasoning(CBR)in the product variant design.The main application of TRIZ evolution theory to construct variants,and to screen the best original understanding,combined with the advantages of the CBR variant design process,summarizes the variant design process.Provide product designers with a variety of variant method guidance.The main research contents are as follows:1.Functional analysis of the product to be modified,and the relevant design structure components are divided.The method of prioritizing the components by the experts is used to determine the core variant components,and to provide clear definition targets for further improvement of the products.2.A more complete case-based reasoning(CBR)variant design process for design data is improved and optimized.Analyze and improve the deficiencies of its existing design process.Improvements In the past,if similar examples were not found in the example knowledge base,the design of the variant relied too much on the status quo of experts and experience.The TRIZ evolution theory is introduced for the imperfect aspects of its variant process,and the evolutionary route is integrated into a more objective concrete evolutionary tree,which provides objective guidance for the structural variants of the variant components and follows the path of technological development.Build new component structure variants or refactor components.3.The specific evolutionary tree path of the deformed component structure,the evolved state sequence formed by deduction,the corresponding morphological matrix is constructed,and a large and comprehensive concept scheme is formed.The PUGH matrix is used to screen and evaluate the scheme for many conceptual schemes.Select the final high-quality concept plan to complete the design and form a complete variant design.4.Analyze the process of generation,screening and optimization of variants,integrate the relevant advantages of CBR variant design,and summarize the complete variant design process.Taking the shredder as an example,based on the process,the analysis and deduction of the conceptual variant of the product are carried out,and the original understanding of the final shredder variant is determined through screening and evaluation steps.Verify the validity and feasibility of the process.
