Research on resource analysis method based on attribute similarity and position weight for conceptual design

Resource analysis is one of the important methods and tools to solve inventive problems in TRIZ. Effective use of resources is the key to form product functional principle innovations and generate technical solutions. In view of the problems that the conceptual design process requires too much experience of designers and is not systematic, the conceptual design is combined with resource analysis method in this paper. Considering the influence of attribute similarity and position weight between components in technical system, an innovative resource analysis method is proposed to accurately exploit available resources in system and super-system to assist the process of conceptual design. The abstract process of resource exploiting in conventional resource analysis methods can be transformed into a specific process of calculating resource similarity by this method. It has the advantages of high computability, strong standardisation and systematisation. The method can not only effectively improve the efficiency and quality of conceptual design, but also lay a theoretical research foundation for the development of computer aided innovation (CAI) software in the future.
