Abstract

Functional design model and in particular FBS model are, in recent years, most commonly accepted design theories to support design process. However, with regard to their use it remains widespread skepticism especially by industry engineers, more inclined to use problem solving methods. Reasons are varied and come from the way in which they approach design problem, often considered too abstract and far from everyday design reality. This paper contains a number of measures to bridge this gap. In particular is proposed an integration between FBS and TRIZ to best rationalize designer efforts in a design process based on a large set of initial requirements. The considered method addresses the determination of the main function and its implementation on the device, and then it starts to iteratively overcome the other requirements (functions) by solving contradictions. In order to obtain more practically feedback, each phase is described with technical parameters. Furthermore the method allows a quickly and economic screening of the alternatives. A design process for a chips waste compactor is carried out by using that process.
