D 3.4 - Testing and validation of re-designed products concepts

This deliverable finishes the Work Package WP3 "Customer-driven products re-design for circular economy" by validation of an intermediate stage of product development process for re-designed parts. It reports the main outcome of Task 3.4 "Testing and validation of re-designed products concepts". Several specifications or requirements defined in D3.1 and D3.2 were referred to validate the achieved develop-ment of single prototypes of the CarE-Service project. Concerning the design of parts as well as the definition of processes of manufacturing and verify-ing several new collaborative approaches for designing products are analysed by viewing developed pro-totypes each. It contains a wider range of re-designed parts distributed to the three value chains for Bat-teries, Metals and Technopolymers of the CarE-Service project. Different levels of technology respectively complexity of prototypes are considered in the different value chains. At least that causes different states of realization too. During the second period the state of battery value chain has been improved since physical demonstrators of module prototypes finished. Also few analyses were performed by testing me-chanical properties. Those have got different purposes depending on which of three value chains consid-ers the prototype.
