Contribution to Integrating Maintainability into Preliminary Design Based on TRIZ

In the face of the competition, the companies have, possibly more than in the past, a need to innovate. However, if the innovation can be of various natures (product, process, methods, organization…), the search for new solutions to technical problems as soon as the Design phase takes a non-negligible part, and certainly constitutes most of the Innovations “radical”, especially when they relate to the product. Conventional methods designed to resolve these problems are often psychological character: methods of creativity. The best known example is the brainstorming session. In all object creation models, of products or of development it is essential, today, to take into account the dimension safety of operation and valuing each project of creation. Of this fact, in addition to the factors related to the optimization of resources, the use of materials and the minimization of releases, it is important to be attentive to the parameters of the safety of operation in the design phase and more specifically to the maintainability of a system repaired. In effect, for its successful integration, and in order to assist teams of design in meeting of creativity or small businesses in the development of their product, we propose a methodological approach based on TRIZ that will solve the problem of the integration of the maintainability in preliminary design phase by generating new concepts of solution in a time reduces which constitutes a decision aid for designers in the case of innovative concepts of product, of space or process. In fact, to succeed its integration, and to assist creative teams in creative sessions or small businesses in the development of their product, we propose a methodological approach based on the TRIZ that will solve the problem of integrating maintainability into the preliminary design phase by generating new solution concepts in reduced time that provide decision support for designers in case of innovative concepts of product, space or process concepts

Intégration de la maintenabilité en phase préliminaire de conception en se basant sur la théorie TRIZ

International audienceL'activité de conception représente un enjeu majeur pour les entreprises, dont la survie dépend bien souvent de la capacité à proposer des produits nouveaux ou développés à moindre coût. Dans ce contexte, la TRIZ propose une démarche intéressante par le fait qu'elle permet de cibler, pour un objectif donné, les problèmes à résoudre. Cette approche conduit à la formalisation d'une solution satisfaisant le problème identifié. De ce fait, elle se distingue des approches traditionnelles de la conception par une durée réduite de génération des concepts de solution et par un nombre restreint de solutions générées. Si l'intérêt de l'application est aujourd'hui reconnu, son intégration pose problème. Dans cette optique, notre travail consiste à intégrer la maintenabilité et la disponibilité en phase de conception préliminaire en se basant sur la théorie TRIZ
