Abstract
In the Conceptual Design Phase of the Integrated Product Development Process (PRODIP) Methodology, conceptual solutions for a new product, or the improvement of an existing one, are developed combining the principles of solution for the product's functions. They are arranged inside different concepts, using a Morphological Matrix. However, as the number of solution principles increases, a combinatorial explosion of the Morphological Matrix may occur, making technical and economic evaluation difficult. This paper presents a systematic approach for determining and exposing the types of relationship between all the functions and also all the principles of solution. Using a robotic platform as a case study, a matrix was developed to showcase the types of existing relationships and the implications of each choice of a specific principle of solution. The result of this approach aided the visualization of which solution principles are not compatible or exhibit a beneficial preference. At the end of the analysis, 394 restraint relations, 165 obligation relations and 626 benefit relations were selected. In addition to decreasing the number of combinations, this proposal identified for evaluation four elementary functions that have a greater impact on the task of creating concepts, improving the creative process.
