Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a tension control device is placed on the surface of the stay to measure tension, then tension measurement is possible, but the device is cumbersome and does not allow continuous monitoring

Engineering Contradiction:
Improvetension measurement capabilityVSAvoidcontinuous monitoring capability
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical tension control devices with an electronic sensor system. The sensor is integrated into the stay structure itself, converting mechanical tension into electrical signals that can be continuously monitored and transmitted wirelessly, eliminating the need for cumbersome external measurement devices.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sensor is embedded within the stay structure, with the measuring device nested inside the guy wire assembly. This integration allows the measurement function to be内置 within the structural element itself, enabling continuous monitoring without adding external bulk or complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If a control device with excessive mass is used to measure stay tension, then the device can be robust, but it leads to inaccuracies in tension measurement

Engineering Contradiction:
Improvedevice robustnessVSAvoidtension measurement accuracy
Core Design Contradiction:
StrengthVSMeasurement precision

Solution Approach 1:

The patent employs thin-film or flexible sensor elements that can be integrated into the stay structure. These thin-film sensors have negligible mass compared to traditional robust control devices, ensuring they do not significantly alter the tension characteristics of the stay while still providing accurate measurement capability.

Inventive Principle:
Principle #30Flexible shells and thin films

3Measurement precision

If prior art devices are used for tension measurement, then basic measurement is possible, but checking tension is tedious and complicated for frequent adjustments

Engineering Contradiction:
Improvetension measurement capabilityVSAvoidtime required for tension checking
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements a feedback system where the sensor continuously monitors stay tension and wirelessly transmits data to a display or mobile device. This real-time feedback eliminates the need for manual tension checking, allowing users to monitor tension levels continuously and make adjustments based on immediate data, significantly reducing the time required for tension management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs automatic tension monitoring and data transmission without requiring user intervention. The sensor self-calibrates and continuously reports tension levels, freeing users from the tedious manual checking process and enabling them to focus on other aspects of equipment management.

Inventive Principle:
Principle #25Self-service
