Prototyping is interwoven with nearly all product, service, and systems development efforts. A prototype is a pre-production representation of some aspect of a concept or final design. Prototyping often predetermines a large portion of resource deployment in development and influences design project success. This review surveys literature sources in engineering, management, design science, and architecture. The study is focused around design prototyping for early stage design. Insights are synthesized from critical review of the literature: key objectives of prototyping, critical review of major techniques, relationships between techniques, and a strategy matrix to connect objectives to techniques. The review is supported with exemplar prototypes provided from industrial design efforts. Techniques are roughly categorized into those that improve the outcomes of prototyping directly, and those that enable prototyping through lowering of cost and time. Compact descriptions of each technique provide a foundation to compare the potential benefits and drawbacks of each. The review concludes with a summary of key observations, highlighted opportunities in the research, and a vision of the future of prototyping. This review aims to provide a resource for designers as well as set a trajectory for continuing innovation in the scientific research of design prototyping.
The book is in response to Skip's years of training and mentoring engineering teams in Design for Six Sigma (DFSS) methods. The teams, excited by their success using DFSS methods, would often ask, \"Do our leaders understand and agree with this approach and will they support us Do they realize that our ability to design a product correctly the first time is compromised by giving us too many projects and too little time\" The result is this book, which pulls together a framework for leaders to exploit the power of Six Sigma to design better workflow and the processes they use throughout the organization.
This book is packed with excellent case studies and examples that explain how to deploy key product design topics, tools and best practices found in modern Product Development processes. The authors specialize in the area of Product Portfolio Development, System Architecture, Conceptual Development and Reverse Engineering. There are dozens of critical design methods, tools and tasks covered in detail. The authors develop both basic methods as well as advanced topics. This text, together with Design For Six Sigma in Technology & Product Development leaves little to the imagination on \"what to do and when to do it\" during product development.
Robust Design is a major tool within the optimization phases of technology development and product design. This text provides a comprehensive and balanced treatment of Dr. Taguchi's remarkable approach to minimizing product and manufacturing process sensitivity to debilitating sources of variation. Robust Design furthers the effectiveness of the engineering team as they seek to understand and exploit interactions between controllable engineering parameters and uncontrollable \"noise\" parameters. The text fully develops how to conduct the process of Robustness Optimization within a modern Product Development Process. As is the PDSS tradition, we show how this tool is used in both technology development as well as product design.
Tolerance Design is a major tool within the design, optimization and verification of product and production process capability phases of a modern Product Development Process. This text is divided between analytical methods for developing tolerances and empirical methods for quantifying tolerance sensitivities within and across complex product and production systems. The analytical section develops a comprehensive process approach using Root Sum of Squares, Worst Case and Monte Carlo Simulation methods. The empirical section uses Designed Experiments, ANOVA and Taguchi Loss Function based methods for tolerance and cost balancing. The book contains numerous examples and case studies to illustrate how to engineer and balance tolerances from the earliest to the final phases of product development. 153554b96e
