ABSTRACT

In this chapter, we discuss the role and use of models as design representations. We first define Models as differentiated from 2D design representations (Chapters 4 and 5) through their physicality as 3D expressions of design intent. We then consider the role of Models as communicators of design ideas between stakeholders during the design process. In particular, we discuss how the physicality of Models as design representations support enhanced communication of intent. We explore how Models may be used as boundary objects for shared discussion, providing opportunities for further development and refinement of possible solution ideas. Various existing approaches to the classification of Models are presented, including taxonomy through the purpose of their use in practice. The physicality of Models as representations of intent is further considered in terms of opportunities for enhanced reflection upon the physical properties of a potential design solution. The multi-model sensory perception afforded by physical model making (i.e. visual, haptic) is also discussed in terms of opportunities to interrogate the form of the design. A taxonomy consisting of eight different Models is presented (Sections 6.2–6.9). The eight types of Models are discussed in relation to their use in practice and reference examples of their application are also provided, together with information on methods of constructing Models.
