Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection by maintenance personnel is used, then the detection method is simple to implement, but the detection accuracy and efficiency are low
Solution Approach 1:
The patent replaces manual visual inspection with an automated electrostatic detection system. A detecting component generates electrostatic field interactions with the insulation layer, and a detecting device measures electrical parameters (current, voltage, impedance) to identify defects. This substitution of mechanical/manual inspection with electrical field-based automated detection significantly improves measurement precision while maintaining manageable system complexity through standardized electrical measurement techniques.
2Productivity
If manual visual inspection is used, then the equipment is simple, but the detection process is time-consuming
Solution Approach 1:
The patent replaces time-consuming manual visual inspection with an automated electrostatic detection system that continuously monitors electrical parameters. The detecting component generates electrostatic fields that interact with the insulation layer, and the detecting device automatically measures and analyzes electrical signals to identify defects. This automation dramatically improves productivity by enabling continuous, rapid detection without manual intervention, while the electrical measurement approach keeps equipment complexity at acceptable levels.
3Measurement precision
If electrostatic detection is applied, then automated detection accuracy is improved, but the detection system complexity increases
Solution Approach 1:
The patent uses the electrostatic field as an intermediary between the detecting component and the insulation layer. The detecting component generates an electrostatic field that penetrates or interacts with the insulation layer, and defects (slits, holes) in the insulation layer alter the electrical parameters (current, voltage, impedance) of this field. The detecting device measures these parameter changes to identify defects. This intermediary approach enables high-precision automated detection while keeping the system relatively simple by leveraging fundamental electrostatic principles rather than requiring complex sensing mechanisms.
