Creative Design Methodology for Mechanical Product CAD Based on Function-Structure and Case

This paper studies the evolution of mechanical products in the brain. Based on the form of the characterization in the evolution, it uses information processing technology and case-based design approach to advance the design and innovation of mechanical products in the way of function-structure and case design. Also an intelligent design in human-computer interaction environment is presented by the parametric method. This work is very important for innovative design of mechanical products and computer´s intelligent design.
