It is presented, how the three types of variation (carryover, embodiment and principle variation) can be distinguished by using the contact and channel approach. As database a more than twenty years lasting case study is used. Therefore the development of the dual mass flywheel in several product generations is considered. Taking the bearing of the system as an example it is analyzed in detail which kind of variation was used and which developmental challenges derived.enConference Paperhttps://www.designsociety.org/download-publication/38889/PGE+-+PRODUCT+GENERATION+ENGINEERING+-+CASE+STUDY+OF+THE+DUAL+MASS+FLYWHEELConference Paper
