Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional monitoring methods are used, then the system is simple and easy to implement, but the ability to detect and predict structural collapse is insufficient
Solution Approach 1:
The patent replaces traditional mechanical monitoring systems with an electric field-based detection system. Electric field sensors measure changes in the electric field environment around structures, which correlate with structural integrity. This substitution enables early detection of collapse precursors without complex mechanical instrumentation, resolving the contradiction between detection capability and system complexity.
Solution Approach 2:
The patent introduces electric field signals as an intermediary parameter to indirectly monitor structural health. Instead of directly measuring structural deformation or stress, the system measures changes in the electric field environment that are caused by structural degradation. This intermediary approach enables reliable collapse prediction while maintaining relatively simple sensor infrastructure.
2Measurement precision
If electric field sensors are installed to monitor structural changes, then the detection precision improves, but the device complexity increases
Solution Approach 1:
The patent monitors changes in electric field parameters (intensity, distribution patterns) as indicators of structural degradation. By focusing on specific electric field parameter changes rather than comprehensive structural measurement, the system achieves high detection precision with relatively simple sensor arrays and analysis methods.
Solution Approach 2:
The system performs preliminary installation of electric field sensors around structures before any degradation occurs. These sensors continuously monitor the electric field environment, detecting subtle changes that precede visible structural damage. This preliminary monitoring approach enables early warning while using simple, distributed sensor networks rather than complex instrumentation.
3Measurement precision
If comprehensive signal analysis is applied to electric field signals, then the prediction accuracy improves, but the processing time and computational complexity increase
Solution Approach 1:
The patent applies signal analysis methods continuously to electric field data, performing preliminary detection of collapse precursors in real-time. By processing signals continuously rather than analyzing data only when degradation is advanced, the system achieves high prediction accuracy without excessive processing delays, enabling timely warnings.

AI summary
A method for monitoring and early warning of structural collapse, having following steps of: installing at least one electric field sensor in a monitoring area, wherein the at least one electric field sensor is used for measuring an electric field signal of the monitoring area; receiving the electric field signal and applying a signal analysis to the electric field signal; and issuing a warning signal when a critical transition feature occurs in the electric field signal to which the signal analysis is applied.
