Using introspection and prototype driven to achieve design analysis in the process of concept generation based on information processing

The research of human´s information processing of design thinking show a key role in many fields such as intelligent design, intelligent manufacturing system and next generation CAD system. In order to form a formalization description and disclose the process of conceptual generation under the interaction of designer and computer environment, This work aims to achieve design analysis for early concept generation and present one improved model integrated cognition and computation to construct one robust process model. In order to meet common sense in designing, introspection and prototype driven should be applied to achieve design analysis in the process of concept generation. And generational variable index of product concept is extracted based on the demands of information processing.
