Knowledge push technology based on quality function knowledge deployment

Abstract

In order to help designers to acquire and apply knowledge, a kind of knowledge push technologies based on quality function knowledge deployment was proposed. During the whole lifecycle of product design, the knowledge requirement house of quality model could link up the required knowledge with design activities to help designers to track the required knowledge for realizing product innovation design. The hierarchical relationship between design tasks, designers, design activities, and required knowledge was analyzed, and the knowledge management system structure for product innovation design based on designers was put forward. Furthermore, knowledge acquisition method was analyzed. In view of the different requirements for knowledge in the different design stages, this paper proposed the mapping model between the process of product innovation design and required knowledge. Then the knowledge push model for product innovation design based on quality function knowledge deployment was established. Finally, a prototype system of computer-aided innovation design platform was developed to implement this knowledge push model, and through its application on the design case of space robot gripper, the practicability and validity of the prototype system were demonstrated.
