Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing techniques for power transmission and distribution systems are used, then the system configuration remains simple, but tower deterioration cannot be detected
Solution Approach 1:
The patent applies multi-functionality by enabling the optical fiber cable to serve dual purposes: its original communication function and a new sensing function for tower deterioration detection. The optical fiber cable acts as both a communication medium and a vibration sensor, detecting tower vibrations through Brillouin scattering effects without requiring separate dedicated sensing cables or power sources.
Solution Approach 2:
The patent implements self-service by using the optical fiber cable's inherent physical properties to detect tower vibrations. The optical fiber cable autonomously detects structural changes through Brillouin scattering caused by vibrations, eliminating the need for external power sources, sensors, or additional detection equipment attached to the tower.
2Reliability
If direct visual inspection or dedicated sensing systems are deployed, then tower deterioration can be detected, but maintenance costs and system complexity increase
Solution Approach 1:
The patent replaces mechanical inspection methods (visual inspection, physical sensors) with optical sensing based on Brillouin scattering. Instead of using mechanical vibration sensors or manual inspection, the system uses light propagation characteristics in the optical fiber to detect tower vibrations, eliminating the need for mechanical contact or power consumption at the tower site.
Solution Approach 2:
The patent introduces optical scattering as an intermediary mechanism to transfer tower vibration information to the detection system. The Brillouin scattering effect acts as a mediator that converts mechanical tower vibrations into optical signal changes that can be remotely detected and analyzed, bridging the gap between the tower structure and the detection equipment.
