Rational Embracing of Modern Prototyping Capable Design Technologies into the Tools Pool of Product Design Teams

Abstract

Today's markets impose wide sets of requirements for new products. The Process of New Product Design, has shifted from sequential Engineering to Concurrent Engineering, for low cost-early market entry. Design Teams must deliver highest quality within minimum time and cost and global crisis worsens things, by further reducing budgets. Prototyping within design processes has become crucial, whereas, available prototyping alternatives have increased. Decisions regarding the use of the most appropriate one, at specific design milestones, affects and much predetermines the success of the product. This paper addresses the problem of "design target"-based embracing of available prototyping alternatives into the tools pool of design teams, in a concise, integrated way. Considering product design teams are expert driven for specific product categories, the introduced approach records the verification intent of designers and binds it to structured Generic Levels of Technical and non-Technical Attribute clusters and associated Design Factors. Furthermore, prototyping experience, manufacturing capabilities and cost of the implementing organization, local industrial status and regulations, are also considered. Utilizing the Analytic Hierarchy Process a complete decision tree leads designers to select the most appropriate prototyping method per design stage. The proposed approach assists implementing organizations and design teams towards cost/time benefits, product risk reduction, decision repeatability and independence. A pilot-model has been developed with "Expert Choice" software and an application example is discussed.

Design Thinking as a Framework for the Design of a Sustainable Waste Sterilization System: The Case of Piedmont Region, Italy

“…Considering its experience and the significant availability of validated case studies, this paper has adopted the DT methodology by d.school from Stanford University structured in five phases [32]: Empathize, Define, Ideate, Prototype, and Test. Since the production costs of a functional prototype are very high and are outside this study's parameters, we intend to generate a design prototype according to the definition proposed by Polydoras et al [33], representing our concept by a CAD model. Consequently, for the test phase, we will evaluate the conceptual design.…”

“…In our study, we intend to create a design prototype according to the definition given by Polydoras et al [33]. Prototypes can be classified according to their ability to serve the distinct stages of the design process; a design prototype mostly represents the form and functional relations of the product.…”

In Search for Shared Characteristics of Physical and Virtual Prototypes

“…Characteristics on the lowest order level of the specific source are marked with an X. Polydoras et al (2011) listed 109 criteria for prototypes on four classification levels in their paper. For space reasons, the lowest level has been omitted here so that only the dimensions of the second and third levels are noted.…”

3D Digital Terrestrial Model Creation Using Image Assisted Total Station and Rapid Prototyping Technology

“…The ability of RP to fast deliver physical objects directly out of digital data, combined with IT supported technological innovations also introduced in areas other than Mechanical Engineering, such as Architecture, Civil Engineering, Medical Sciences, Art, Mathematics, Biology, Archaeology, Paleontology, as well as Survey Engineering with Geographic Information Systems (GIS), has led to noticeable widespread of RP utilization, (Dimitrov et al 2006), to ongoing investigation of effective RP application (Polydoras et al 2011) and to interdisciplinary approaches and applications, like the one presented in this paper.…”
