The book "Conceptual Design for Engineers" by Michael Joseph French offers a comprehensive and in-depth analysis of engineering design based on the principles of engineering science. Originally published in 1971, it remains relevant even after nearly three decades, as it addresses central design issues that are often only superficially covered in other textbooks. The author places particular emphasis on the development of ideas and their refinement, which is illustrated through numerous examples and systematic approaches. The book highlights the importance of insight and scientific understanding in the design process and demonstrates how recurring design problems can be identified and solved. It is a valuable resource for engineering students and professionals looking to deepen their design skills.
