Abstract
In the field of design, concept plays a significant role in the constitution of a design object. As a concept designates a goal for a design process, it has to be deliberately defined in order to maximize the functionality of the object. In other words, the concept should play a mechanical and an organic role at the same time. In their writings What Is Philosophy? Gilles Deleuze and Félix Guattari define the concept as a mechanical component that consists of sensory elements, each of which is itself a concept. We transplant their thought to the field of design as a tool capable of evaluating the sensory quality of the design object.
