Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual detection methods are used (visual observation or tapping), then detection can be performed with simple equipment, but it takes large amounts of time and cost
Solution Approach 1:
The patent replaces manual mechanical detection methods (visual observation and tapping) with an automated optical detection system using OTDR (Optical Time-Domain Reflectometry). The system uses optical fibers to detect utility pole abnormalities automatically, eliminating the need for manual inspection while significantly improving detection speed and efficiency.
2Productivity
If optical fiber monitoring is used to detect extreme states (nesting or breakage), then detection automation is achieved, but it is very difficult to detect subtle deterioration states
Solution Approach 1:
The patent changes the detection parameter from monitoring only extreme stress states (nesting, breakage) to monitoring vibration characteristics across a broader range. By analyzing vibration patterns and frequencies, the system can detect subtle deterioration states that do not significantly affect optical fiber stress, thereby improving detection sensitivity while maintaining automation.
3Measurement precision
If dedicated detection structures are installed in utility poles, then detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent utilizes existing communication optical fibers already installed in utility poles for dual purposes: both communication and deterioration detection. By making the optical fiber serve multiple functions, the system achieves accurate detection without requiring additional dedicated detection structures, thereby reducing device complexity and cost.
