7.6 Guidelines

155

Industrial equipment and high-cost products21 that do not have to be changed often, are, economically speaking, more suited to re-manufacturing. Is important to design for the recovery of disposed products, with marketing campaigns or re-collection logistics. Ultimately, it is essential to provide an adequate infrastructure for storage and inventory. To facilitate re-manufacturing, it is of paramount importance to have favourable removal, replacement and interchangeability processes for the components of the entire product line (cf. Chap. 9). Guidelines for facilitating re-manufacturing: • Design and facilitate removal and substitution of easily expendable components • Design structural parts that can be easily separated from external/visible ones (Example 7.23) • Provide easier access to components to be re-manufactured • Calculate accurate tolerance parameters for easily expendable connections • Design for excessive use of materials in places more subject to deterioration • Design for excessive use of material for easily deteriorating surfaces (Example 7.24)

Examples 7.23 Wilkhahn, Germany, is a producer of office furniture. They have developed new product lines that follow the guideline of separating structural components from external elements. This was related to the objective of recovering discarded furniture and reselling after re-manufacturing. 7.24 For the cylinders of several motorbike models pistons with an enlarged diameter are available. It is possible to remove the light ruling from the interior cylinder walls with an adjusting operation that removes a small part of the materials. In the end, only pistons (with an enlarged diameter) have to be replaced, not the entire engine.

7.6.8 Intensifying Use Designing for the intensified use of products (and/or their components) entails design orientation towards multifunctional products and common replaceable components or products for integrated function.
