Description

<p> In the development of product design, a methodology is required for how a desired design concept realized by an appropriate function and appearance. However, the design concept itself is not clear, and there are differences in recognition between the requester and the implementer. In this paper, we show that it can be semantically defined in terms of intension and extension, and further reduce it to a direct sum expression. Using direct sum means that the expression by the set of design concepts can be finally expressed based on the disjunctive normal form (DNF). By displaying this DNF on the positioning maps, we proposed a method to relate the requester to the implementer. To verify the proposed method, we assumed that prototype cups by a 3D printer as the product market and create positioning maps by conducting a limited survey. We also showed that it is possible to create a new design concept for the function and appearance from the cup market.</p>
