CLASSIFYING PHYSICAL MODELS AND PROTOTYPES IN THE DESIGN PROCESS: A STUDY ON THE ECONOMICAL AND USABILITY IMPACT OF ADOPTING MODELS AND PROTOTYPES IN THE DESIGN PROCESS

Abstract

This paper discusses model making approaches in the design process and also classifies broadly the different types of physical models and prototypes. It also describes the fundamental principles of different methods of model making and prototyping and questions how they can be used in the conceptual and detailing design stages of the design process. The first part of this paper explains how physical model and prototypes are classified and why it is so important for gaining a better understanding of the designed product in terms of usability and technical functionality. The second part of this paper focuses more specifically on how these tools are helpful or restrictive in facilitating the creation of ideas, concepts and detailed design solutions following the various stages of the design process. Finally a user-centered and cost-efficiency design perspective will be discussed with respect to what extent models and prototypes are able to facilitate design changes throughout the different stages of the design process.
