Abstract: 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.

Abstract: A method and system for multi-participant based conceptual design information modeling. The method includes the following steps. Initial design information generated by a plurality of design participants involved in different design stages during conceptual design of a target product is acquired. The initial design information is screened to obtain target design information in a target carrier form according to a carrier form corresponding to the initial design information. Subject information is extracted from the target design information. Based on a plurality of visualized forms under a plurality of dimensions, a plurality of visualized views of the subject information are generated under the plurality of dimension. A visualized view corresponding to a display authority of a design participant is displayed on the graphical user interface. The design participant can modify the design information based on the visualized view to obtain a target design information model.
