Scenario-Based Design Knowledge Acquiring and Modeling in Collaborative Product Design.

Collaborative product design is a typical complex problem-solving process where designers' knowledge and expertise are always tactic and implicit. This paper depicts the concept of design scenario and the scenario-based design knowledge acquiring in a cognitive approach. Through a cognitive experiment based on protocol analysis and sketch analysis in terms of scenario-based collaborative product design, a model of scenario-based knowledge acquiring in product design is proposed. The model includes two types of spontaneous design knowledge acquiring method - concept-driven knowledge acquiring and data-driven knowledge acquiring, which indicates that design knowledge acquiring is a process of scenario moving. On the basis of the model, a scenario-based computer aided product design system CBID is developed to improve the ability and quality of collaborative product design of seven Chinese corporations.
