7.6.4 Facilitating Maintenance By maintenance is meant periodic preventive activities13 and slight adjustments. Appropriate maintenance can help to avoid environmental and economic costs of repairs, as well as the impact of the disposal and production entailed in replacing a product14. As with repairs, many complex products that are meant to be durable require proper maintenance activities that have to be facilitated by adequate design solutions15. Guidelines for facilitating maintenance: • • • • •

Simplify access to and disassembly of components to be maintained Avoid narrow slits and holes to facilitate access for cleaning Pre-arrange and facilitate the substitution of short-lived components Equip the product with easily usable tools for maintenance Equip products with diagnostic and/or auto-diagnostic systems for maintainable components • Design products for easy onsite maintenance • Design complementary maintenance tools and documentation • Design products that need less maintenance

Examples 7.10 Nexus is a modular structure for washing machine disassembly. The structure consists of five functional subassemblies that can be disassembled into components and homogeneous materials. Example 7.10 The structure of the Nexus washing machine, Electrolux

E.g. changing oil or replacing the chain, tooth rim or the pinion of a motorbike. Fine tuning of a car extends its lifetime. Besides, it reduces petrol consumption (smaller costs) and emissions of toxic exhaust gases (smaller impact). 15 Cf. Chap. 9. 14
