Designing Component Interfaces for the Circular Economy—A Case Study for Product-As-A-Service Business Models in the Automotive Industry

The resource-intensive automotive industry offers great potential to avoid waste through new circular business models. However, these models require technical innovations that enable the rapid dismantling of add-on parts. In this paper, we design mechanical interfaces fast and non-destructive while still fulfilling all requirements develop a general model for evaluation disassembly capability. For purpose, current options parts are first examined evaluated concerning defined KPIs using example front bumper. Based on analysis, as well various solution principles interface concept can be derived. necessity removing neighboring components is identified main challenge dismantling. Two different concepts were developed by inserting an intermediate level connecting part between bumper module. We prove redesigning reconstructing number process steps required remove could reduced roughly 60% compared solutions. methodology should applied other vehicle create greater positive environmental, economic societal impact.
