This publication provides a comprehensive overview of the principles of industrial design, guiding you through the entire product development process from the initial concept to final materialization. The book systematically explores the conceptual foundations of practical design, beginning with requirement analysis and goal setting. It details methods for identifying user needs, defining functional criteria, and analyzing the market environment. The text then delves into the product development process itself. It covers the journey from initial hand sketches and detailed technical drawings to digital two- and three-dimensional visualizations. Further sections are dedicated to physical model making, the creation of functional and aesthetic prototypes, and the use of rapid prototyping methods. The importance of iterative refinement, usability testing, and systematic feedback processing is also highlighted. A significant portion of the book focuses on materialization and manufacturing in industrial design. You will learn about strategic material selection, examining the characteristics of metals, wood, plastics, and composites. It also presents an in-depth look at industrial manufacturing techniques, including forming, cutting, and joining processes, as well as surface treatment and finishing. Finally, the book applies these principles to the specific field of furniture design. It addresses the fundamentals of ergonomics, structural stability, and the development of modular furniture systems. Special attention is given to practical case studies, including the design of an industrial design shelf and the specific construction challenges of an industrial design wall shelf. This includes topics such as material combinations, connection details, assembly logic, and methods for wall mounting.
