Study and application on aided innovation design method based on semantic analysis and TRIZ theory

For the situation that complexity of the design method, high demand of knowledge for the designers in the conceptual design process, and which is difficult to realized, this paper presents the solving process of innovative problems based on the TRIZ theory. Ontology and knowledge database is constructed based on TRIZ. The application-oriented knowledge database is constructed, and the description of innovative problems are associated with knowledge. The innovative design method is developed for designers to achieve the relevant knowledge. And the aided innovation system is developed based on semantic analysis technology, which can automatically recognize the description of the problem. The feasibility and effectiveness of the innovative design method and the aided innovation system is verified through the case of innovative design of the coupling diaphragm component.
