Abstract

Solution Space Development: Conceptual Reflections and Development of the Parameter Space Matrix as Planning Tool for Geometry-based Solution Spaces

Highlights

  • The steady increase of competitiveness, innovation and complexity in many companies has driven the progress of computer-aided design (CAD) and computer-aided engineering (CAE) tools in the recent 20 years

  • Since until now no computer-aided tools for the joint elicitation of requirements, parameter hierarchies and restrictions exist, we developed the Parameter Space Matrix (ParSM)

  • At first glance, modelling with ParSM seems to be more complicated than simplified because requirements and restrictions have to be modelled as well. This is only apparently the case because the model planning aspect is typically present in parametric CAD design of multi-variant products, but is rarely documented [3, 5]. An example of this is the various skeletal techniques used for the respective CAD systems [2]

Summary

INTRODUCTION

The steady increase of competitiveness, innovation and complexity in many companies has driven the progress of computer-aided design (CAD) and computer-aided engineering (CAE) tools in the recent 20 years. Of particular interest for adaptive and variant design is the use of parametric design systems, in which the shape of a component or an assembly is modelled, and their describing parameters [1]. Constraining parameters mathematically or logically allows implementing explicit knowledge like dimensioning formulae or design rules within the digital prototype [2]. In relation to adaptive and variant design, the designer does specify the product shape of a single component and the control and configuration concept and describes a solution space [3, 4]
