Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar transmission signal is directed to monitor a safety area around an object, then the safety monitoring coverage is improved, but the energy consumption increases due to irradiation of larger areas
Solution Approach 1:
The patent applies dynamics by making the aperture angle of the radar transmission signal adjustable and adaptive. The control system dynamically adjusts the aperture angle based on the detected position and size of the object, ensuring the safety area is completely covered while minimizing irradiation of areas outside the safety zone. This dynamic adaptation resolves the contradiction by optimizing energy consumption while maintaining complete safety monitoring coverage.
2Reliability
If the radar transmission signal covers the entire safety area, then the monitoring completeness is improved, but the device complexity increases due to need for direction adjustment mechanisms
Solution Approach 1:
The patent applies universality by integrating multiple functions into a single control system. The control system not only adjusts the aperture angle but also controls the direction of the radar transmission signal and processes the reflected signals to detect objects in the safety area. This multi-functional integration achieves complete safety area monitoring while avoiding the need for separate complex mechanical adjustment mechanisms for each function.
3Measurement precision
If the radar transmission signal direction is adjusted to track moving objects, then the tracking precision is improved, but the response time decreases due to continuous adjustment requirements
Solution Approach 1:
The patent applies preliminary action by having the control system continuously adjust the radar transmission signal direction and aperture angle based on predicted object positions. The system proactively maintains optimal coverage of the safety area around moving objects rather than reactively adjusting after objects move, thereby maintaining high tracking precision while minimizing response time delays.
