Abstract-2 -We integrated two research traditions -one focusing on analogical reasoning, the other on knowledge sharing -with the aim of examining how designers' unique knowledge backgrounds can fuel analogy-based creativity. The present dataset afforded a unique opportunity to pursue this aim since the design dialogue derived from team members with highly disparate educational backgrounds. Our analyses revealed that analogies that matched (versus mismatched) educational backgrounds were generated and revisited more frequently, presumably because they were more accessible. Matching analogies were also associated with increased epistemic uncertainty, perhaps because domain experts appreciate the challenge of mapping such analogies between domains. Our findings support claims from the knowledge-sharing literature for a direct route from knowledge diversity through analogical reasoning to novel idea production.

Such prior experience and knowledge then serves to inform a solution for the current design problem, shaping both its initial development and its subsequent refinement. Indeed, the very notion of 'design-by-analogy' (e.g., Helms, Vattam, & Goel, 2009;Moreno et al., 2014) points specifically to the frequent capacity for designers to transfer solution structures or elements from a known source domain to a target design problem.In studying such design-by-analogy, researchers have often tended -perhaps inadvertently -to control out individual variation in the background domain knowledge of the designers being analysed, instead focusing on homogeneous participants with very similar backgrounds in terms of their design education, training and company-based experiences, for example, in domains such as industrial product design (e.g., Ball, Ormerod, & Morley, 2004), electronic engineering design (e.g., Jagodzinski, Reid, Culverhouse, Parsons, & Phillips, 2000) or the design of medical plastics (e.g., Christensen & Schunn, 2007). In the extreme case of numerous laboratory experiments that have investigated design-by-analogy the source analogies are presented directly to individual participants in the form of one or more initial examples for perusal (e.g., Casakin, 2004;Casakin & Goldschmidt, 1999;Goldschmidt, 1995). In this way very tight constraints are placed on the experimental setting so that the researcher can assess the specific role that such source materials have on the design process and the resulting design products. These latter kinds of laboratory studies are actually rather paradoxical, since although it is assumed that analogy sources in real-world design practice are frequently drawn from a designer's own background knowledge and experience, the examination of analogy use i...
