| The ability to innovate is the core driving force for the development of an enterprise and a country.Providing innovative resources in the conceptual design stage will help to seek new fundamental understandings and reflect product innovation.The scientific effect library helps to find new principles and understandings.The research on scientific effects has been carried out in China for many years.With continuous in-depth research,it is found that all scientific effects can be decomposed into the interaction between substance attribute.Substance and substance attribute are the basic elements for constructing all technical systems,and attribute are the basic resources for analyzing and solving problems.The construction and improvement of any technical system cannot be separated from the utilization and mining of substance attribute.Therefore,in-depth study of the attribute of substance is of great significance for improving or reconstructing the function of technical systems to achieve innovation.This paper studies the relationship model between functions,effects and attribute,as well as the construction principles and methods of a knowledge graph-based substance attribute library.First,the main models and corresponding knowledge tools for solving problems using TRIZ theory are studied,and the usage scenarios and scope of various tools when encountering problems are summarized.At the same time,the relationship between ontology and knowledge graph,and knowledge graph construction principles and methods.The main research contents are as follows:Based on the relationship between function and effect,effect and attribute in TRIZ theory,combined with the analysis of FBS(function-behavior-structure)model,a relationship model of FEA(function-effect-attribute)is proposed,at the same time,the process of using attribute analysis tools to solve system problems is studied,and a case study of pumping units is carried out.Summarized the scope of application of material property analysis,the application scenarios of the material property knowledge base are clarified.Based on the "substance-attribute-parameter-quantity" model in U-TRIZ,combined with practical application requirements,it is determined to take engineering materials as the research object,and use ontology technology to build ontology model of material property knowledge base,then,the storage of ontology data is completed through the parsing and dimensionality reduction processing of ontology.Based on the above research,through requirement analysis and environment construction,the structure and function of the knowledge base system are designed.Completed the construction of the material property knowledge base system based on Neo4 j,gave the process of knowledge query and the realization process of visual display,at the same time,it provides the function of knowledge editing,so as to realize the continuous filling of data and improve the knowledge base.In addition,this paper integrates the scientific effect library into the knowledge base system,integrates the effect and attribute base,and finally completes the development of the knowledge base system. |
