About the Introduction of a Dialogue-Based Interaction within CAD Systems

Abstract

AbstractCAD systems are nowadays extending their domain of application towards the preliminary phases of the design process, with the emergence of Computer-Aided Innovation – CAI. However, the first generation of CAI commercial software is far from achieving the intended objectives; among them, the diffused TRIZ-based systems made no exception. Particular limitations are highlighted within the embodiment design stage with reference to the support provided by CAx tools in fulfilling product specifications, whenever the generated solutions do not satisfy system requirements.The authors propose to overcome the current limitations by implementing a dialogue- based system into the framework of existing CAD applications, to support the designer in overcoming problems emerged during the initial design stages. The manuscript illustrates a refined set of requirements for a Dialogue-Based CAD system according to the outcomes of a testing campaign carried out with a preliminary version of a question-answer framework...
