Engineering Contradiction Analysis
1Measurement precision
If sensors are installed on conductor lines and ground lines to measure tension values and other parameters, then ice coating thickness can be detected, but the installation becomes complex and requires power outages
Solution Approach 1:
The patent uses image copying instead of physical sensor installation. By capturing images of the power transmission lines and using image processing algorithms to extract ice coating information, the system avoids the need to install complex sensors on the conductors and ground lines, thereby simplifying installation while maintaining detection accuracy
Solution Approach 2:
The patent replaces the mechanical sensor-based measurement system with an optical imaging system. Instead of using physical sensors to directly measure tension and other parameters, the system uses cameras to capture images and then processes these images computationally to derive ice coating thickness, eliminating the need for complex mechanical sensor installations
2Measurement precision
If sensors are installed to measure tension values and other parameters, then ice coating thickness can be determined, but maintenance cost and difficulty increase
Solution Approach 1:
By using image copying instead of physical sensors, the patent eliminates the maintenance burden associated with sensor installation and repair. The imaging system can be maintained remotely without requiring physical access to the power transmission lines, significantly improving maintenance ease while preserving detection capabilities
Solution Approach 2:
The replacement of mechanical sensors with an optical imaging system transfers the maintenance requirement from the field to the office. The camera system can be maintained and calibrated remotely, while the computational analysis is performed in a controlled environment, greatly simplifying maintenance operations
3Measurement precision
If sensors are installed on power transmission lines, then ice coating thickness can be measured, but power outages are required during installation
Solution Approach 1:
The patent uses image copying to eliminate the need for direct sensor installation on live power transmission lines. By capturing images during normal operation and processing them later, the system avoids requiring power outages for sensor installation, thereby reducing time loss while maintaining measurement accuracy
