Virtual Design for Repair: The Case of a Gearmotor

Abstract

‘Repair’ in the design process of products can prolong the life cycle of parts: this is substantiated by a few examples that put this ideology into practice. Among many other products, home printers could be a good example, with huge numbers of printers ending up in landfill after a relatively short life; often due to blocked print heads that are either impossible or too expensive to replace. The act of fixing things can both prolong the life of an artifact, and create new values through the process of engagement for its users. However, the prohibitive cost of repair makes it inaccessible or unfavorable this practice for many. In this paper a preliminary approach to Design for Repair is proposed, in order to virtually test an industrial case study and to show a comparison between a product, that was intended to disposal after a failure of some components, and the same product re-designed, by taking into account how to repair parts in easy and effective way. Redesign of parts in some cases can be very effective and the virtual test can be easily reproposed in practice, for industrial products. Advantages in the repair of parts is evident in terms of sustainability and circular economy pursuit. This paper suggests a sequenced method to approach the Design for Repair and provide the virtual model of a re-designed solution that could replace the previous one in order to make the repair of components easy and effective. The economic analysis on the effective convenience of repair faced to the disposal of a product was not developed within this context.
