Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are used to detect objects on a medium, then detection coverage and reliability are improved, but detection accuracy deteriorates due to errors between sensor detection results caused by deviations in relative positional relationships
Solution Approach 1:
The patent replaces mechanical alignment methods with an optical field-based correction system. A correction unit generates correction values based on detected positional deviations and applies them to adjust the detection results, substituting physical mechanical adjustment with computational optical field correction to maintain both multi-sensor reliability and measurement precision
Solution Approach 2:
The patent changes the parameters of the detection system by introducing correction values that adjust the detection results based on actual positional deviations. The correction unit modifies detection parameters dynamically to compensate for manufacturing tolerances and assembly variations, allowing the system to maintain high detection accuracy while using multiple sensors
2Manufacturing precision
If sensors are fixed rigidly to achieve stable positional relationships, then manufacturing precision is improved, but adaptability deteriorates when positional deviations occur
Solution Approach 1:
The detection device performs self-correction through the correction unit, which automatically detects positional deviations and generates correction values to adjust detection results. This self-service mechanism eliminates the need for external manual realignment while maintaining manufacturing precision and providing adaptability to positional variations
Solution Approach 2:
The patent implements a feedback loop where the detection unit continuously monitors positional relationships, the correction unit processes deviation information, and correction values are applied to adjust detection results. This feedback mechanism maintains manufacturing precision while providing real-time adaptability to positional deviations
