L’analyse des phénomènes physiques, éléments essentiels vers la résolution de problèmes industriels

Abstract

In this paper, we present the different elements of connection between users requirements and physical phenomena created during the use of products. We propose a structured methodology which goes from the analysis of the significant moments until the identification of the appreciation criteria of the user and design variables necessary to the product definition. The time decomposition of the product use in significant moments makes it possible to identify all actions realized by the user, to extract the physical effects and to qualify them in term of relevance. The methodological tools ensure the exhaustiveness of the analysis, to define the physical sizes associated with the criteria and the design variables as well as the relations between the criteria and design variables. Then we can take into account users requirements during preliminary design phase. This methodology is applied to the integration of the user requirements at the time of the opening for a telephone foldable.
