Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single detection hole is used in the detection tip, then the device structure is simple, but the detection accuracy varies greatly depending on the operator's posture and experience
Solution Approach 1:
The detection tip is segmented into multiple detection holes (first detection hole, second detection hole, third detection hole) positioned at different locations and orientations. This segmentation allows the detection system to capture hydrogen leakage from multiple angles simultaneously, eliminating the need for precise operator positioning while maintaining structural simplicity.
2Ease of operation
If the detection tip is positioned at an inaccurate angle or distance from the inspection site, then the inspection process is easier to perform, but the detection accuracy decreases
Solution Approach 1:
The detection tip transitions from a single-point detection approach to a multi-dimensional detection array. By positioning detection holes at different spatial coordinates (different angles and orientations), the system creates a volumetric detection zone that accommodates various operator positions and angles, making the inspection process more forgiving and easier to perform correctly.
3Measurement precision
If multiple detection holes are added to improve detection accuracy, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
Multiple detection holes are merged into a single integrated detection tip structure. The first, second, and third detection holes are combined in one component that connects directly to the hydrogen detector, eliminating the need for multiple separate sensors or complex positioning mechanisms while achieving improved detection accuracy.
