Filling a new need in engineering education, Getting Design Right: A Systems Approach integrates aspects from both design and systems engineering to provide a solid understanding of the fundamental principles and best practices in these areas. Through examples, it encourages students to create an initial product design and project plan.

Classroom-tested and industry-reviewed, the text focuses on the steps of a basic design cycle. It first defines the problem, establishes technical requirements, and identifies the customer value proposition. The text then explores the design space, optimizes design choices, and develops the architecture, including behavior, control, and structure. After validating the design, the author presents an accessible treatment of resource-constrained scheduling as a computer puzzle. The final chapter covers the level-by-level decomposition of systems. In addition, the appendices offer useful design challenges for a bathroom-cleaning robot, a home health-care monitoring system, a night-vision system for automobiles, and an Internet-based meal delivery system.

Using a design approach based on simple text-based tools and spreadsheet software, this book presents a formal process for discovering requirements and tackling design problems. It will help mature audiences in professional settings as well as students with limited design and project experience.

In creating the value-added product in not distant future, it is necessary and inevitable to establish a holistic and though-evoking approach to the engineering problem, which should be at least associated with the inter-disciplinary knowledge and thought processes across the whole engineering spheres. It is furthermore desirable to integrate it with trans-disciplinary aspects ranging from manufacturing culture, through liberal-arts engineering and industrial sociology.

The thought-evoking approach can be exemplified and typified by representative engineering problems: unveiling essential features in Tangential Force Ratio and Interface Pressure, prototype development for Bio-mimetic Needle and application of Water-jet Machining to Artificial Hip Joint, product innovation in Heat Sink for Computer, application of Graph Theory to similarity evaluation of production systems, leverage among reciprocity attributes in Industrial and Engineering Designs for Machine Enclosure and academic interpretation of skills of mature technician in Scraping .

Without standardized construction elements such as nuts, bolts, bearings, beams, resistors and the like, the design of physical equipment is hopelessly inefficient, and engineers are continually bogged down with re-designing these elements over and over again. The same can be said for the domain of ideas and performance requirements. Only through a process of standardization of the corresponding functional elements will systems engineering truly live up to its potential of increased efficiency and quality.

This book discusses concepts of good design from social perspectives grounded in anthropology, sociology and philosophy, the goal being to provide readers with an awareness of social issues to help them in their work as design professionals. Each chapter covers a specific area of good practice in design, explaining and applying a small set of related concepts to a series of case studies, and including a list of additional sources recommended for further study. The book does not assume any specialized, technical background knowledge; it is not a how-to book that offers technical instruction. Yet, it focuses on the assessment of designs, addressing concepts qualitatively (with a small exception for the concept of risk). Based on an established university course on Design and Society at the Centre for Society, Technology, and Values that the author offers for students from a variety of disciplines, the book represents a valuable resource for students in engineering, architecture and industrial design - helping prepare them for careers as design professionals - and for all readers in design-related professions interested in understanding a side of design that they may well never have considered systematically. Because of its broad scope and non-technical presentation style, the book may also appeal to general readers interested in social issues in design and technology.

In this monograph, the authors demonstrate how the integration of adaptability, operability, and re-configurability in the design of complex systems is indispensable for the further digitization of engineering systems in smart manufacturing. Globalization of the customer base has resulted in distributed and networked manufacturing systems. However, current design methods are not suitable to address variations in product design, changes in production scale, or variations in product quality necessitated by dynamic changes in the market. Adaptability, operability, and re-configurability are key characteristics that are necessary to address the limitations of the current methods used to design networked manufacturing systems. In recent years, the digital transformation driving Industry 4.0 has had an enormous impact on globally distributed manufacturing. Digitalisation, the integration of digital technology into networked engineered systems, is increasingly being adopted to respond to changes in the market. This is achieved by means of (a) the concurrent design of adaptable systems, (b) addressing flexibility in design parameters, (c) conducting an operability analysis, and (d) employing a reconfiguration strategy to address faults and variances in product quality and re-establish connectivity among the elements in the system. The design of manufacturing systems in the age of Industry 4.0 is addressed in this monograph. The authors introduce the concept of a 'smart platform' and a computational framework for the digitalization of networked manufacturing systems. They also suggest how the framework and techniques in this monograph are applicable beyond the manufacturing domain for architecting networked engineered systems in other industries such as chemical processes and health care, that are being transformed through the adoption of the Industry 4.0 construct.

Advances in Product Family and Product Platform Design: Methods & Applications highlights recent advances that have been made to support product family and product platform design along with successful applications in industry. This book provides not only motivation for product family and product platform design (i.e., address questions about "why and when should we platform") but also methods and tools to support the design and development of families of products based on shared platforms (i.e. address the "how" and "what" questions about platforming). It begins with a general overview of product family design to introduce the general reader to the topic and then progress to more advanced topics and design theory to help designers, engineers, and project managers plan, architect, and implement platform-based product development strategies for their company. Finally, successful industry applications provide readers and practitioners with case studies and "talking points" to become platform advocates and leaders within their organization.

Adhesively-bonded joints provide many advantages over conventional mechanical fasteners and are increasingly receiving attention as an alternative to mechanical joints in engineering applications. The traditional fasteners usually result in the cutting of fibers and hence the introduction of stress concentrations, both of which reduce structural integrity. By contrast, bonded joints are more continuous and have potential advantages of strength-to-weight ratio, design flexibility, and ease of fabrication. This book provides an overview of available analytical methods as well as numerical methods.

Naturebot: Unconventional Visions of Nature presents a humanities-oriented addition to the literature on biomimetics and bioinspiration, an interdisciplinary field which investigates what it means to mimic nature with technology. This technology mirrors the biodiversity of nature and it is precisely this creation of technological metaphors for the intricate workings of the natural world that is the real subject of Naturebot. Over the course of the book, Barilla applies the narrative conventions of the nature writing genre to this unconventional vision of nature, contrasting the traditional tropes and questions of natural history with an expanding menagerie of creatures that defy conventional categories of natural and artificial. In keeping with its nature writing approach, the book takes us to where we can encounter these creatures, examining the technological models and the biotic specimens that inspired them. In doing so, it contemplates the future of the human relationship to the environment, and the future of nature writing in the 21st century. This book will be of great interest to students and scholars of biomimetics, environmental literary studies/ecocriticism, and the environmental humanities.

This book proposes a novel approach to the design of accessible and inclusive sailing yachts, inspired by the principles of "Design for All." The goal is to allow anyone, including users with disabilities and individuals belonging to the weaker segments, to sail without barriers. Starting from an analysis of existing pleasure boats, the author identifies a series of factors limiting the accessibility or usability of external and internal spaces. In turn, he discusses the most suitable solutions to each. By proposing an extensive set of design solutions applicable to the confined spaces on yachts, and which comply with the relevant anthropometric and dimensional rules, the book offers a timely snapshot of the potential benefits and applicability of an inclusive approach to yacht design, setting a new reference standard for inclusive and accessible nautical design.

The subject of vibro-acoustics is important for the design of machine elements and structures, to minimize sound generated by them. For better machine designing, it is necessary for machine designers (mechanical engineers) to have a thorough knowledge of vibro-acoustics. Furthermore, since the design cycles of machines have become shorter, designers will have to design quiet machines at the drawing-board stage rather than applying "band-aid" techniques after the machine has been built. Although there is common ground in the treatment of acoustics, the subject of vibration is not very fortunate. Those interested in low-frequency vibration are generally concerned with the modal approach of using natural frequencies and mode shapes, whereas those interested in vibro-acoustics in medium and high frequencies are generally concerned with the wave approach. Since both modal and wave approaches have their advantages, it is a good idea to study both together to get the best out of them. This is useful for a better understanding the physics of vibro-acoustics. Written for students and professionals interested in gaining knowledge, this book systematically integrates the relevant aspects of vibro-acoustics from various viewpoints.
