Abstract: Freeman-Newell model is improved by introducing behavior
information. A structure cognitive model based on function and behavior
is constructed to describe an elementary problem-solving process.
Concept space, the model for describing conceptual design process, is set
up based on the proposed structure cognitive model. The relationship
between design elements in concept space is represented by Boolean
vectors/matrices to make it readily manipulated by computers, and the
formalization of conceptual design process is presented. The conceptual
design of an industry sewing machine is used as a case study to
illustrate the proposed model and approach.
Key words: Conceptual design Freeman-Newell model Concept space
