Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If design data is modified based only on thermal stress analysis results, then manufacturing deformation can be compensated, but the accuracy of design modification is insufficient because use performance is not considered
Solution Approach 1:
The patent merges thermal stress analysis results (manufacturing phase) with stress distribution analysis results (use phase) into a single comprehensive design modification process. By combining these two previously separate analyses, the system achieves higher accuracy in design data modification than either analysis could provide alone.
Solution Approach 2:
The patent performs preliminary estimation of both manufacturing deformation and use performance before finalizing design data. By conducting these estimations in advance and integrating their results, the system prepares comprehensive correction information that improves the accuracy of subsequent design modifications.
2Ease of manufacture
If only manufacturing deformation is considered in design modification, then production feasibility improves, but overall design accuracy deteriorates due to lack of performance optimization
Solution Approach 1:
The patent changes the parameters considered in design modification from solely manufacturing-focused (thermal stress) to a dual-parameter approach that includes both manufacturing deformation characteristics and use-phase stress distribution characteristics. This parameter expansion enables more accurate design information determination.
3Measurement precision
If design data modification considers both manufacturing and use phase analyses, then design accuracy improves, but computational complexity increases
Solution Approach 1:
The patent segments the complex analysis into distinct phases: manufacturing phase analysis (thermal stress), use phase analysis (stress distribution), and integrated synthesis. By dividing the overall task into manageable segments that can be processed separately and then combined, the system handles computational complexity more effectively while maintaining high accuracy.

AI summary
An information processing method includes estimating deformation of an object that is likely to occur during manufacturing of the object to obtain a first estimation result, the object including a unit structure, estimating performance of the object that is likely to be exhibited during use of the object to obtain a second estimation result, and determining design information of the object based on the first estimation result and the second estimation result.
