Focus on reparability

Longmuss, Joerg; Dworak, Christian

Technical equipment is subject to various forms of service life restrictions. Ideally, the material used for its production is then reintegrated into the material cycle. For the effective use of resources, these cycles must be closed at the highest possible level and slowed down as much as possible. Functional losses or restrictions of individual components must not lead to a permanent failure of the device. Therefore, repairs should be made easy and cost-effective. In an extension of the Eco-Design Directive a number of requirements are already being formulated to facilitate repairs. However, complying with an obligatory directive does not create a competitive advantage for companies. This creates the danger that companies will only implement reparability as far as it is mandatory. For a device to be easy to repair, however, more requirements must be taken into account. These requirements make the development process more complex and the product design can no longer be optimized exclusively for assembly in production, but repair must also be taken into account. In order to achieve a design that is suitable for repair, it is therefore necessary to take into account more complex manufacturing processes, higher material costs and higher design costs. A proactive advancement of reparability as a paradigm in product development can therefore only be expected if there is a prospect of additional income. Therefore, new business models that make an increase in reparability economically interesting for both producers and consumers are the best option. Three business models are presented here for which BSH Hausgeräte GmbH already has practical experience. After a brief description of each model, the current status of these entrepreneurial experiences is presented.
