Case-based transformational design method based on personal specification

In this paper, the authors present a method of designing a new product suited for the personal image. The method consists of two phases. In the first phase, a concept space is formed by using personal images of several existing design cases. In the second phase, a new product is designed by using some primitive operators which are generated by calculating the relative position of several similar design cases in the concept space. This method has the feature that it can create products from the viewpoint of a user´s personality, because a concept space is formed based on each user´s personal images of existing cases. The authors performed an experiment to confirm whether the picture suited for personal image is created by this method. They discover the effectiveness of this method through the experiment
