Resumo
This article proposes a new descriptive framework, which we label as the “ideation
framework” (IF), of the design process from a dual cognitive-engineering perspective,
partly based on existing frameworks from both fields and previous work by the author.
The framework is for the ideation or front-end phase of the product development
process, representing the interface between cognitive psychology and engineering
design. Three domains – inspiration, decomposition, and integration – and three
spaces – problem-space, idea-space, and concept-space – are the elements of the
framework. The iterative flow of the engineering design process passes through the
three domains in a semi-controlled way, through a sequence of specialization and
generalization process loops in and between the spaces. An empirical descriptive
examination of the ideation process is performed using designers with limited design
experience. The designers were faced with a design problem that they had to solve in a
limited period of time. Their designs were analyzed, and a post-exercise interview was
done to uncover each of the participants’ design process. The empirical work indicates
these designers worked in a manner largely consistent with the IF.
