A COMPARATIVE ANALYSIS OF THE THEORY OF INVENTIVE PROBLEM SOLVING AND THE SYSTEMATIC APPROACH OF PAHL AND BEITZ

摘要

This paper presents a comparative analysis of two design methodologies; the Theory of Inventive Problem-Solving (TIPS) and the systematic approach of Pahl and Beitz (SAPB). The methodologies are compared with respect to a number of aspects; similarities and differences are highlighted. It is then suggested that a more powerful methodology may result if the methodologies are unified and that such a unification should use SAPB as an underlying design process model being complemented by TIPS elements at certain points. This is because the SAPB has a wider scope as a design process model, covering the whole process from task clarification to detail design and component as well as systems design, whereas TIPS features some very useful elements (engineering systems evolution laws, standards and principles) that are not included in the SAPB.
