Scenario-based Design Knowledge Acquiring and Application in Collaborative Product Design

Collaborative product design is a problem-solving process where designers´ knowledge and expertise is always tactic and implicit, in the area of which knowledge acquiring is the difficult problem. This paper depicts the concept of design scenario and the process and pattern of design knowledge acquiring in a cognitive approach. Through a scenario-based collaborative product design cognitive experiment based on protocol analysis and sketch analysis, a model of scenario-based knowledge and acquiring in product design is proposed. The model considers that design knowledge acquiring is a process of scenario moving which includes the two types of spontaneous design knowledge acquiring method: concept-driven knowledge acquiring and data-driven knowledge acquiring. On the basis of the model, a scenario-based CAD product design system - CBID is developed to improve the ability and quality of collaborative product design of Chinese corporations
