This book brings together some of the most influential pieces of research undertaken around the world in design synthesis. It is the first comprehensive work of this kind and covers all three aspects of research in design synthesis: - understanding what constitutes and influences synthesis; - the major approaches to synthesis; - the diverse range of tools that are created to support this crucial design task. The chapters are comprised of cutting edge research and established methods, written by the originators of this growing field of research. They cover all major generic synthesis approaches i.e., composition, retrieval, change and repair, and tackle problems that come from a wide variety of domains within architecture and engineering as well as areas of application including clocks, sensors and medical devices. The book contains an editorial introduction to the chapters and the broader context of research they represent. With its range of tools and methods covered, it is an ideal introduction to design synthesis for those intending to research in this area as well as being a valuable source of ideas for educators and practitioners of engineering design.
