The algorithm for invention-problem solution is the main method to analyze and solve problems in TRIZ theory, and its goal is to solve physical contradictions of problems. The algorithm is mainly aimed at technical systems with complex problems, contradictions and unclear related components. It is a non-computational logical process of a series of deformation and redefinition of the initial problem, which realizes the gradual and in-depth analysis and transformation of the problem and finally solves the problem. The algorithm especially emphasizes the contradiction of the problem and the standardization of the ideal solution. On the one hand, the technical system evolves to an ideal solution; On the other hand, if a technical problem has contradictions to overcome, it becomes an innovative problem.

TRIZ believes that the difficulty of solving an innovative problem depends on the description and standardization of the problem. The clearer the description, the higher the standardization of the problem, and the easier it is to solve the problem. In ARIZ, the process of solving innovative problems is the process of constantly describing and standardizing problems. In this process, the most fundamental contradiction of the initial problem is clearly revealed. If this problem can use the existing data in the solution library, there is a standard solution; If the existing data can't solve this problem and there is no standard solution, we need to wait for the further development of science and technology. This process is realized by ARIZ algorithm.
