Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection methods are used to spot-check the visual inspection system, then the system can detect hardware issues, but the inspection efficiency is low and time-consuming
Solution Approach 1:
The visual inspection system performs self-diagnosis by automatically detecting its own hardware status and algorithm availability through standardized test images and automated comparison processes, eliminating the need for manual inspection while maintaining high reliability
Solution Approach 2:
The system performs preliminary spot-checks using pre-prepared standardized test images with known defect types before actual production inspection, allowing hardware and algorithm availability to be verified in advance without affecting production efficiency
2Reliability
If comprehensive spot-checking of all cameras and algorithms is performed, then system reliability is improved, but the inspection time and complexity increase
Solution Approach 1:
The system performs spot-checks on a selective basis rather than comprehensive inspection of all cameras and algorithms simultaneously. It uses standardized test images to partially verify system components, achieving sufficient reliability without excessive time investment
Solution Approach 2:
The spot-check process is segmented into independent modules: hardware availability detection for each camera, algorithm availability detection, and defect type verification. These can be performed separately and efficiently, reducing overall inspection time while maintaining reliability
3Productivity
If the visual inspection system operates without regular spot-checks, then productivity is maintained, but the accuracy of inspection results deteriorates due to hardware drift
Solution Approach 1:
The system implements periodic spot-checks at scheduled intervals during production operations. This rhythmic verification ensures hardware and algorithm availability are maintained without continuously interrupting production, balancing productivity with inspection accuracy
Solution Approach 2:
The system provides feedback through automated detection of hardware status and algorithm performance using standardized test images. When deviations are detected, the system generates alerts or reports errors, enabling timely corrections to maintain inspection accuracy without compromising productivity
