1Area of stationary object

If traditional sensors are used to measure physical parameters, then local measurement can be achieved, but global monitoring of the entire bridge structure cannot be realized

Engineering Contradiction:

Improvemonitoring coverage areaVSAvoidmeasurement sensitivity

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The bridge structure is divided into multiple monitoring sections, with quantum sensors deployed at different locations. Each quantum sensor pair monitors a specific segment, and the results are integrated to achieve comprehensive global monitoring while maintaining high measurement precision at each location.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The quantum sensor system is designed to monitor multiple physical parameters simultaneously (stress, strain, temperature, vibration) across the entire bridge structure using a unified quantum sensing platform, enabling both global coverage and detailed local measurement.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If traditional sensors are used for data collection, then offline data collection can be performed, but real-time monitoring cannot be achieved

Engineering Contradiction:

Improvemonitoring efficiencyVSAvoiddata processing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The quantum sensors are pre-configured and calibrated before deployment on the bridge structure. The quantum entanglement state is prepared in advance, enabling immediate real-time monitoring upon activation without requiring extensive setup or offline calibration periods.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The traditional mechanical data collection and processing system is replaced with a quantum sensing system that provides continuous real-time measurements. The quantum state changes respond instantaneously to structural parameter changes, eliminating the time delay inherent in traditional offline data collection methods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If traditional sensors are used for measurement, then general monitoring can be performed, but detection of micro-structural changes with high sensitivity is limited due to noise and environmental factors

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The quantum sensor acts as an intermediary between the bridge structure and the measurement system. The quantum entangled state serves as a sensitive mediator that transduces minute structural changes into measurable quantum state changes, amplifying the detection signal while filtering out environmental noise through quantum correlation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system exploits changes in quantum state parameters (entanglement fidelity, correlation coefficients) in response to structural parameter changes. By monitoring these quantum parameter changes rather than direct physical quantities, the system achieves enhanced sensitivity to micro-structural changes while being less susceptible to classical noise sources.
