Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical fiber sensors are installed in various locations to monitor multiple targets, then the coverage and monitoring capability are improved, but the system complexity and difficulty of managing multiple monitoring functions increase
Solution Approach 1:
The patent applies universality by enabling optical fiber sensors to perform multiple monitoring functions simultaneously. The system can detect various physical quantities (temperature, strain, vibration, acoustic waves) using the same optical fiber infrastructure, allowing a single sensor network to serve multiple monitoring purposes across different locations and applications.
Solution Approach 2:
The patent combines multiple sensing functions into a unified optical fiber sensing system. By integrating detection capabilities for different physical quantities and combining signal processing methods within a single system framework, the patent reduces the need for separate monitoring systems while expanding functionality.
2Adaptability or versatility
If multiple sensing functions are integrated into a single optical fiber system, then the versatility is improved, but the difficulty of detecting and measuring specific targets among multiple superimposed signals increases
Solution Approach 1:
The patent extracts specific sensing information from superimposed optical signals by separating different signal components. Using signal processing techniques, the system isolates individual sensing data (temperature, strain, vibration, acoustic waves) from the combined optical signal, enabling precise identification of each monitoring target despite the superimposed nature of the signals.
Solution Approach 2:
The patent introduces signal processing methods as intermediary mechanisms between the optical fiber sensors and the final measurement results. These processing techniques act as mediators that decode the superimposed signals, translating complex combined signals into distinct, identifiable monitoring data for different targets.
3Measurement precision
If optical fiber sensing is used for advanced monitoring applications, then the measurement precision is improved, but the device complexity increases due to the need for sophisticated signal processing
Solution Approach 1:
The patent replaces complex mechanical or electronic sensing systems with optical fiber-based sensing. By using optical methods instead of traditional mechanical sensors, the system achieves high measurement precision while the complexity is managed through optical signal processing rather than complex mechanical assemblies.
