Extension of the Pahl & Beitz Systematic Method for Conceptual Design of a New Product

Abstract

The systematic method for conceptual design of a new product has been introduced as a comprehensive design tool by Pahl and Beitz in 1977 and improved since. In our studies the method has been extended by introduction of new techniques and tools, that enable to be more specific and more focused. The design methodology is called ICDM – Integrated, Customer Driven, Conceptual Design Method. Three out of the new ICDM tools are shortly described in this paper. These tools are the Enriched QFD for task definition, the CFMA – Conceptual Failure Mode Analysis and the DQM – Design Quality Measurement to evaluate the satisfaction from the generated concepts. The other new tools like the CDTC – the Conceptual Design To Cost, the Roobustool – to evaluate and improve the robustness of the solution combination, the RTA – the Risk and Time to Market Analysis and the DSO - the Direct Synthesis Optimization, are only shortly mentioned. ICDM has been used extensively in many Israeli start-up companies and also in classical industrial companies that adapted the method to their special needs.
