A method and system for strategically solving an innovative design problem are provided. A target analysis tool is determined according to a to-be-solved problem. An initial model is generated based on the target analysis tool. A target model is determined according to an interaction relationship among elements in the initial model and the target analysis tool. A problem characterization result of the target model is generated according to a preset interaction relationship. Retrieval information is generated according to the problem characterization result, based on which the retrieval is performed in a preset database to obtain target data. Different analysis tools can be used to analyze different to-be-solved problems. The retrieval is performed based on the problem characterization result to obtain the solution to the to-be-solved problem.
