Research on Product Technology Evolutionary Potential Mapping System Based on TRIZ

Making strategic decisions for product development is one of the toughest jobs that managers of research and development have in enterprises. Identifying EP (evolutionary potential) of product is a crucial step that can give help to this process. The patterns and lines of technology evolution belong to technology forecasting of TRIZ (theory of inventive problem solving) are applied to identify EP of a technical system and help decision-makers to make strategic decisions. This article introduces a searching method for EP and develops the radar plot structure of EP. A process of mapping EP of product based on patent analysis is then formed. Based on these techniques, software named EPMS (evolutionary potential mapping system) was developed. As an illustration the EP of washing machine in China was mapped by EPMS.

TRIZ Application in Conceptual Design of Packaging Machine for Dropping Pill of Chinese Traditional Medicine

In this paper, a conceptual design of packaging machine for dropping pill of Chinese traditional medicine based on TRIZ is introduced. The IFR (Ideal Final Result) of the product is obtained by the evolution patterns of TRIZ. The function structure of the packaging machine for dropping pill is established. The model of substance-field is used to identify the design problem and the design conflicts are confirmed by use of conflict determining diagram. Contradiction matrix and 40 inventive principles in TRIZ are used to solve the conflicts. At last, the conceptual design of packaging machine for dropping pill of Chinese traditional medicine is accomplished, which can guarantee the filling accuracy
