Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional inspection methods (ultrasonic, macroetch, eddy current, X-ray/CT) are used to detect chemical anomalies, then detection capability is maintained, but inspection time becomes excessively long and resources are consumed
Solution Approach 1:
The inspection process is segmented into multiple passes: a first pass using lower resolution settings to cover large areas quickly, followed by a second pass using higher resolution settings to inspect identified regions of interest. This segmentation allows the system to maintain detection capability while significantly reducing overall inspection time by avoiding uniform high-resolution scanning of entire components.
Solution Approach 2:
The system applies partial action by performing high-resolution inspection only on specific regions of interest rather than the entire component surface. The first pass identifies potential anomalies, and the second pass focuses resources only on those specific areas, avoiding the excessive time consumption of comprehensive high-resolution scanning while maintaining adequate detection capability.
2Measurement precision
If high-resolution scanning is applied to the entire component surface, then detection precision is improved, but inspection time increases significantly
Solution Approach 1:
The inspection system applies local quality by using different scanning resolutions in different regions of the component. High-resolution scanning is applied locally to regions of interest identified in the first pass, while the majority of the component surface is inspected using lower resolution settings. This approach maintains detection precision where needed while preserving overall inspection efficiency.
Solution Approach 2:
High-resolution scanning is applied partially only to specific regions of interest rather than uniformly across the entire component. This partial application of high-resolution scanning maintains detection precision for potential anomalies while avoiding the excessive time consumption that would result from comprehensive high-resolution scanning of all surfaces.
3Productivity
If multi-scan strategy with different resolutions is implemented, then inspection efficiency is improved, but system complexity increases
Solution Approach 1:
The inspection system implements dynamics by automatically adjusting scanning parameters based on inspection progress and identified features. The system transitions from lower resolution scanning in the first pass to higher resolution scanning in the second pass, dynamically adapting the inspection strategy based on previously identified regions of interest. This dynamic adjustment improves efficiency without requiring complex manual intervention.
Solution Approach 2:
The system uses feedback from the first inspection pass to guide the second pass. Regions of interest identified during the initial lower-resolution scanning trigger targeted high-resolution re-inspection. This feedback mechanism allows the system to automatically optimize inspection resources based on actual findings, improving efficiency while managing complexity through algorithmic control rather than manual complexity.
