This paper is a study investigating the application of the concept of "representation" to industrial designs and creation. The essence of representation is the process of signification, and the way human beings understand the world is in fact a process in which things are signified or signs are interpreted. Therefore, this paper attempted to study the combination principle of signs in order to assist in the ideation and design of industrial products, trigger emotions, and generate creative ideas. This paper utilizes the concept of "representation" in semiotics to develop creative concepts to be applied to industrial designs. The study results show that the signs in the products could be recombined as elements to stimulate the association of viewers, and by means of such a method, to shape the emotional charm of the products. Innovative ideas could be generated through viewers' misinterpretation of the signs, which gave rise to thinking different from the past.. The above two principles, if properly grasped, and the three thinking paths concluded in this paper, if followed, can help to trigger emotions and generate innovative ideas in the process of creation. It is hoped that they can serve as a reference for creation for designers who aspire to study "representation" as the central theme of their designs in the future.
