Conceptual design involves identification of required functions of the intended design, generation of concepts to fulfill these functions, and evaluation of these concepts to select the most promising ones for further development. The focus of this paper is the second phase-concept generation, in which a challenge has been to develop possible physical embodiments to offer designers for exploration and evaluation. This paper investigates the issue of how to transform and thus synthesise possible generic physical embodiments and reports an implemented method that could automatically generate these embodiments. In this paper, a method is proposed to transform a variety of possible initial solutions to a design problem into a set of physical solutions that are described in terms of abstraction of mechanical movements. The underlying principle of this method is to make it possible to link common attributes between a specific abstract representation and its possible physical objects. For a given input, this method can produce a set of concepts in terms of their generic physical embodiments. The method can be used to support designers to start with a given input-output function and systematically search for physical objects for design consideration in terms of simplified functional, spatial, and mechanical movement requirements.

“…Such design processes would start with a functional requirement and end with a concept that will have to be detailed further in subsequent design stages. These methods include genetic programming (Koza et al, 2003), agents governed by simulated annealing (Campbell et al, 1999) case-based reasoning (Han and Lee, 2006), hierarchical decomposition and re-composition (Chakrabarti, 1994;Chiou and Kota, 1999), and others.…”

Many methods that support human creativity by manual or computational means have been proposed in the past. They rely on the assumption that following a certain process of reasoning might lead to generating ideas considered creative. We start by defining creativity as a capability that enables the creation of systems that are patentable. We review the state-of-the-art of creative conceptual design and organize it with a framework. Subsequently, we present a method called infused design that guarantees generating design solutions by transforming systems and methods from remote disciplines. In many cases, these solutions would be deemed creative. Finding these systems and their transformations is done through a process based on the underlying discrete mathematical representation. This process is partially supported by a computer tool.We describe the method of infused design and illustrate its operation through part of the results achieved until now, including designing a new active torque amplifier system. We 2 further demonstrate its benefits through other examples. We discuss the relation of infused design with other creativity or design methods and conclude with future developments of the method."A well-directed imagination is the source of great deeds." Chinese proverbKeywords: creativity; conceptual design; graph representation; collaborative design; design support systems; framework; analogy INTRODUCTIONConceptual design is a central stage in product design; it determines the principles that govern the product. Decisions made in this stage have major impact on the final product quality, cost, and market success (Pahl and Beitz, 1996). But even high quality conceptual design leading to high quality products does not guarantee product success. If a company wishes to capture or maintain its market leadership, it must do better than that; it must develop breakthrough or radical innovations (McDermott and O'Connor, 2002).Our position in this paper is that creative conceptual design (CCD) is central to developing innovative products. Therefore, studying and improving CCD is an important undertaking.However, creativity and innovation are elusive concepts; to some it is mysterious. There are more than 80 definitions of creativity in the literature (Dasgupta, 1994). A common definition of creativity is that creativity is the ability to generate new useful things that are characterized by being original and imaginative. The meaning of these properties is open to interpretations; therefore, for the purpose of this study we adopt a particular definition: CCD outputs a description of a device or a system that is or judged to be patentable. This definition concentrates on the engineering functionality of products rather than on their industrial design or 3 esthetics. We also focus on determining the principles that govern the product rather than a precise description of its structure and its detailed embodiment.In section 2, we review the state-of-the-art of creative conceptual design. We provide a framework that ...
