Extended sequence modelling in design engineering - Gaining and documenting knowledge about embodiment function relations with the C&C2-approach

Abstract

In embodiment design, functions are implemented in a technical systems embodiment. For doing so, design engineers need to understand the relations of embodiment and function. Many systems change their states during function fulfilment which complicates their relations and leads to ambiguity in design decisions. The challenge for design engineers is that they often need to make important decisions about the design before they can use sophisticated analytical models to investigate them. This contribution presents a structure for the C&C2-Sequence Model as a non-analytical model to support design engineers in modelling embodiment function relations. This structure contains four dimensions that are derived from the state of the art and preliminary work. It enables the structuring of gained knowledge about embodiment function relations and supports their communication in design engineering teams. Two development projects in academic and corporate environment are conducted using the structure to investigate its applicability. In these projects, design engineers were able to document and use gained knowledge about the investigated complicated systems.
