… What are they?
As Philipp has already mentioned, integration and functionalization are the key concepts. The door module carrier serves as a frame on which a whole host of other components are mounted – inner and outer shells, speakers, locking module, crash sensor, motors for raising and lowering the windows, and so on – plus the window regulator rails, which used to be fitted in a separate work step. Now the rails are injection-molded straight onto the molded organic sheet. The module also opens up new options for acoustic design, and the load-path-optimized fiber reinforcement offers up to 400 percent greater energy absorption than the previous carrier design.
