1Measurement precision

If conventional simulation methods are used to improve simulation accuracy, then the simulation accuracy is improved, but the system cannot support efficient additional analysis of notable phenomena

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The simulation system is divided into two distinct simulation modes: a first simulation for improving accuracy by adjusting parameters based on actual results, and a second simulation for enabling additional analysis of notable phenomena. This segmentation allows each simulation type to optimize for its specific purpose without interfering with the other, thereby resolving the contradiction between accuracy improvement and analysis capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary simulation to identify notable phenomena and their corresponding parameter ranges before conducting additional analysis simulations. By pre-identifying the phenomena of interest and setting appropriate parameter ranges based on first simulation results, the system prepares the groundwork for efficient additional analysis, thus enabling both accuracy improvement and analysis support.

Inventive Principle:

Solution Approach 1:

The system executes a first simulation to establish baseline accuracy and identify notable phenomena before performing additional analysis. By using the results of the first simulation to determine parameter ranges and select phenomena for further analysis, the system avoids unnecessary comprehensive simulations, thereby reducing overall analysis time while maintaining accuracy improvement benefits.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of performing exhaustive simulations across all parameter ranges, the system focuses computational resources on partial simulations targeting specific notable phenomena identified in the first simulation. This selective approach performs only the necessary additional simulations required to analyze identified phenomena, reducing wasted computational time and resources.

Inventive Principle:
Principle #16Partial or excessive action
