Abstract The CK theory provides a clear explanation framework for engineering design, which opening up the black box of engineering design and problem solving process. An analysis and comparison of different systematic innovative methods are carried out based on the CK theory, depicting their basic procedures to suggest that classical contradiction matrix of TRIZ, together with USIT and ASIT, have their own merits, limitations and possible ways of improvement.On the basis of previous theory driven comparison, four prominent features of an "idealized innovative method" can be concluded, namely problem refinement, problem standardization, introduction of knowledge and verification of solutions.
