Research And Application Of Extension Evolution Design Metho

Innovation is an important theme to promote social progress,promote product renewal and accelerate economic development.Innovation is not only about technological innovation,but also about method innovation.The application of appropriate innovation methods can greatly improve the efficiency of solving innovative problems,shorten the problem solving cycle,reduce R&D costs and achieve rapid iteration of technical products.The TRIZ theory based on patent statistical analysis summarizes the laws of some technological innovation problems,such as the theory of technological system evolution,but it is too abstract and fragmented;Extenics provides a formal method to solve contradictions and innovation problems,but it cannot provide a transformation operation tool close to the actual application scenario to achieve the relevant technological innovation goals.Therefore,this paper attempts to combine the qualitative analysis of TRIZ theory with the formal analysis of Extenics to design a set of technological innovation problem solving mode that not only includes the general mechanism to solve innovation problems,but also provides the corresponding operable solutions,In order to give full play to the pre guidance of technological innovation methods on technological innovation practice.The main contents of this study include:(1)According to the formal development trend of technology innovation methods,the existing evolution route is formalized by applying the primitive theory of extenics,and a relatively perfect extension model is constructed to reveal the key features in the process of technology system evolution with a formal structure.(2)The extension analysis rules of extenics are applied to extend the evolutionary route in multiple dimensions,so as to enrich the set of relevant evolutionary operators;Build the product primitive expansion rules along the evolutionary route,guide the primitive expansion process with the evolutionary rules,reduce the disorder of divergent thinking in the expansion process,and improve the efficiency and operability of primitive expansion applications.(3)Carrying out formal and quantitative research on extension transformation and conduction effects involved in the implementation of evolution route,and build product transformation rules based on evolution route: firstly,establish the primitive models involved in evolution route;Then,according to the relevant rules of domain knowledge and extenics,the relationship between matter elements is established;Then the conduction transformation in the evolutionary process is analyzed according to the categories of the evolutionary route;Finally,the method of establishing the general relationship between the evolutionary path and the extension transformation and conduction effect is summarized,so as to accurately depict the essence of its transformation and clarify its relevant operators.(4)Based on the construction of the above evolution path description model,combined with extension case retrieval,a component evolution mechanism starting from the initial instance node is designed and applied to a microfluidic chip design problem.Based on the extension innovation,reasoning and evolution route,a method of using historical case structure to infer future case structure is constructed;Establish the design case data decomposition method of historical products,the structure of case library,and the case retrieval and matching algorithm;Taking the retrieval result case as the initial case,the evolution path and hierarchical evaluation index system of the case scheme are established;Finally,according to the actual situation of a certain design field,explore the application process of this design process.
