Research studies have shown that there is an industry demand for improved failure analysis as well as failure documentation and this could be accomplished by model-based failure analysis methods. Furthermore, it is shown that the embodiment of design is an important aspect, which supports the product developer during the design process. Motivated by these findings, the authors combine the Failure Mode and Effect Analysis (FMEA) method and Contact and Channel Approach (C&C˛-A). The resulting function- and embodiment-based method focusses on failure mechanisms, thereby improves the analysis and documentation of failures. The results are exemplified and discussed based on two real use cases: the development of a pneumatic gear shift actuation system for a race car and the development of an inline quality control system for a CNC turning machine.
