Method for organizing and applying design knowledge supporting product innovation

Abstract

The invention provides a method for organizing and applying design knowledge supporting product innovation, comprising the following steps of (1) dividing the design knowledge supporting the product innovation into principle knowledge, comprehensive knowledge and field knowledge; the comprehensive knowledge and the field knowledge are collectively called design fact knowledge; (2) expressing the design fact knowledge using a physical characteristic layer, expressing the principle knowledge by using an innovation property layer, and expressing the incidence relation between the physical characteristic layer and the innovation property layer using a knowledge semantic layer; (3) constructing an internal semantic network side to organize the principle knowledge; (4) constructing an external knowledge resource network side to organize the design fact knowledge; (5) constructing the relation between the internal semantic network side and the external knowledge resource network side; and (6) constructing a design knowledge base application system facing the product innovation, and providing brand new, tracking and improved three different knowledge application models for product innovation design according to the requirements of design tasks.

Description

technical field [0001] The invention belongs to the technical field of product development, and in particular relates to an organization and application method of design knowledge in the process of product innovation design. Background technique [0002] The product design process is a process of design knowledge from abstraction to concreteness, gradual refinement, and repeated iterations. It is a process of materialization of design knowledge. With the continuous emergence of various new technologies and new knowledge, knowledge for product innovation design has the characteristics of wide range, complex disciplines, and various forms, and often exists in various high-dimensional, massive, heterogeneous, incomplete, and semi-structured Among the design resources, the product design process has increasingly become a process of multidisciplinary knowledge integration. Design knowledge is the driving force and source of product innovation activities, and its effective manage...

Problems solved by technology

Although this kind of research has greatly improved the innovative ideas of designers, it often makes the specific process of product innovation design fail because it cannot provide the explicit design experience knowledge hidden behind the tacit principle understanding knowledge.

[0005] In addition, although the knowledge organization form based on the design catalog has the advantages of simple structure and good keyword search technology, the phenomenon of "vocabulary island" produced by it is not conducive to the generation of creative design solutions

Due to the lack of sufficient knowledge self-extension and comprehension ability of professional vocabulary, the "word-to-class" knowledge application technology adopted by it is essentially a "point-to-face" relationship. This asymmetrical mapping relationship will greatly limit the innovation of designers. Effective expansion of ideas
