Analysis of requirements, generation of architectural concepts, and definition of interfaces in system engineering are closely related to recognition and resolution of inevitable conflicts between different functions and requirements. As a rule, such conflicts are not resolved but rather alleviated through trade-offs or compromises, which reduces the overall system effectiveness. The authors describe a compromise-free structured approach to resolving architectural and interface conflicts in automotive system using TRIZ methodology. The principles of TRIZ-based conflict-resolution are explained and examples of typical conflicts in automotive engineering and typical solutions given.
