Engineering Contradiction Analysis
1Measurement precision
If coupled analysis of composition flow and mold deformation is performed to increase computation accuracy, then computation accuracy is improved, but computation time increases
Solution Approach 1:
The patent divides the computational process into two distinct segments: a first computational method for rapid estimation and a second computational method for high-accuracy verification. This segmentation allows the system to perform quick initial assessments without immediately undertaking time-consuming coupled analyses, thereby reducing overall computation time while maintaining accuracy where needed.
Solution Approach 2:
The patent changes the computational parameters and methods based on the stage of analysis. The first computational method uses simplified parameters and assumptions for speed, while the second method employs comprehensive physical phenomenon parameters for accuracy. This parameter change strategy enables the system to adapt computational complexity to operational requirements.
2Measurement precision
If high-accuracy computation considering multiple physical phenomena is executed, then computation accuracy is improved, but computation time per computation increases
Solution Approach 1:
The patent applies partial action by using the first computational method that considers only essential physical phenomena for initial assessments, rather than always executing complete coupled analyses. This partial computation approach provides sufficient accuracy for decision-making while significantly reducing computation time and increasing productivity.
Solution Approach 2:
The first computational method creates a simplified copy or approximation of the full physical model, capturing key behaviors without all the computational complexity. This approximate model allows rapid evaluation of multiple scenarios without requiring the full high-accuracy computation each time.
3Manufacturing precision
If loop processing with multiple computations is performed to widen search range, then decision quality is improved, but total decision time increases
Solution Approach 1:
The first computational method performs preliminary actions by quickly evaluating multiple parameter sets before committing to high-accuracy computations. This preliminary screening identifies promising candidates, reducing the number of subsequent expensive coupled analyses needed and thereby shortening total decision time while maintaining quality.
Solution Approach 2:
The system uses feedback from the first computational method's rapid evaluations to guide which parameter sets warrant further high-accuracy analysis. This feedback mechanism ensures that loop processing focuses computational resources on the most promising options, improving decision quality efficiency.

AI summary
A simulation apparatus that predicts a behavior of a curable composition in a film forming process includes a processor configured to execute behavior computation of the curable composition by a computational method selected from a first computational method and a second computational method which shortens a computation time as compared to the first computational method. The processor is configured to execute behavior computation of the curable composition by the second computational method while applying each of a plurality of tentative parameter sets for the film forming process, decide, from the plurality of tentative parameter sets, a parameter set that produces a result of the behavior computation satisfying a predetermined criterion for evaluation, and execute behavior computation of the curable composition by the first computational method while applying the decided parameter set.
