Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If handheld detection devices like hyperspectral imaging cameras are used, then detection capability is improved, but device cost and operation cost increase
Solution Approach 1:
The patent replaces expensive handheld hyperspectral imaging cameras with inexpensive fixed temperature sensors that continuously monitor temperature. This substitution uses low-cost components to achieve the detection function, directly addressing the contradiction between detection capability and device cost.
Solution Approach 2:
The patent replaces the mechanical handheld inspection method with an automated optical-thermal detection system using fixed temperature sensors and image processing. This substitution eliminates the need for manual operation and expensive portable equipment while maintaining detection effectiveness.
2Measurement precision
If handheld detection devices are used with fixed patrol manner, then detection capability is improved, but labor requirements increase
Solution Approach 1:
The system performs self-monitoring through fixed temperature sensors that automatically detect temperature changes and generate alerts without human intervention. The automated image processing and threshold comparison enable the system to serve itself, eliminating the need for manual patrol operations.
Solution Approach 2:
The patent replaces manual patrol operations with an automated computer vision system that processes thermal images and detects leaks automatically. This substitution transforms a labor-intensive mechanical process into an automated electronic system.
3Area of stationary object
If multiple detection devices are installed around pipelines, then detection coverage is improved, but construction cost increases
Solution Approach 1:
The patent uses a single fixed temperature sensor to perform multiple detection functions across different areas by capturing thermal images and analyzing temperature variations throughout the monitored space. This multi-functional approach replaces the need for multiple separate detection devices.
Solution Approach 2:
The patent transitions from point-based detection (single sensor location) to area-based detection by using thermal imaging to capture temperature distribution across the entire monitored space. This dimensional change allows comprehensive coverage without installing multiple sensors.
4Adaptability or versatility
If hyperspectral imaging camera is used to determine presence of multiple gases, then detection versatility is improved, but operation complexity increases
Solution Approach 1:
The patent detects different gases by monitoring temperature changes rather than analyzing spectral characteristics. This parameter change from spectral analysis to thermal monitoring simplifies the operation while maintaining the ability to detect various gases that cause temperature variations upon leakage.
