Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional x-ray inspection methods are used to perform comprehensive comparison with three-dimensional design data and evaluation of thickness and internal defects, then measurement precision and reliability are improved, but inspection time and processing time are significantly increased
Solution Approach 1:
The patent divides the three-dimensional design data and specimen into multiple sliced planes along the z-axis. By processing and comparing corresponding sliced planes separately, the system achieves comprehensive inspection coverage while reducing the computational and inspection time required for complete three-dimensional analysis.
Solution Approach 2:
The patent extracts and eliminates the z-axis component by projecting three-dimensional data onto two-dimensional sliced planes. This extraction allows the inspection system to focus on critical two-dimensional cross-sections, significantly reducing inspection time while maintaining measurement precision for thickness and defect detection.
2Reliability
If comprehensive inspection of entire specimen is performed to ensure complete performance evaluation, then reliability of production process evaluation is improved, but productivity and inspection efficiency are reduced
Solution Approach 1:
The patent segments the specimen inspection into multiple sliced planes, allowing the system to evaluate critical sections independently. This segmentation enables reliable performance evaluation of production processes by examining key cross-sections without requiring exhaustive inspection of the entire specimen volume.
Solution Approach 2:
The patent applies partial action by inspecting selected sliced planes rather than the entire three-dimensional specimen. By choosing representative cross-sections that capture critical features and potential defects, the system achieves sufficient reliability for performance evaluation while dramatically improving inspection efficiency and productivity.
