Abstract: "While there is a visible increase of publications in the area of design thinking and signs that it is becoming a serious area of research, there is a lack of theoretical approaches that directly address its domain specific characteristics. This study attempts to develop such a theory directed towards design reasoning based on a protocol study and formal notation, among other things. Three domains of reasoning are described: construction, object, and representation. Inference making within and between these domains is described in terms of operations called functions and states called structures in a state-space representation of design. Five types of mapping which are illustrated by the protocol study are described using structures and functions.Both shortcomings and strengths of the proposed theoretical formalisms are discussed. Future work is indicated."
