摘要
Representations in engineering design can be hand sketches, photographs, CAD, functional models, physical models, or text. Using representations allows engineers to gain a clearer picture of how a design works. We present an experiment that compares the influence of representations on fixation and creativity. This experiment presents designers with an example solution represented as a function tree and a sketch, we compare how these different external representations influence design fixation as they complete a design task. Results show that function trees do not cause fixation to ideas compared to a control group, and that function trees reduce fixation when compared to sketches. Results from this experiment show that function tree representations offer advantages for reducing fixation during idea generation. (C) 2015 Elsevier Ltd. All rights reserved.
