Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar signal direction is fixed, then the device structure is simple, but the safety zone cannot be completely illuminated when the object moves
Solution Approach 1:
The patent implements dynamic beam control where the radar signal direction is continuously adjusted to track and illuminate the safety zone around moving objects. The control system modifies the beam direction based on object position feedback, ensuring complete safety zone coverage while the object moves through the monitoring area.
Solution Approach 2:
The system uses feedback from object detection to continuously adjust the radar beam direction. The control system receives information about object position and movement, then modifies the beam orientation accordingly to maintain proper safety zone illumination throughout the object's trajectory.
2Reliability
If the radar signal illuminates a wide area, then the safety zone is completely covered, but energy consumption increases due to unnecessary irradiation outside the safety zone
Solution Approach 1:
The patent applies local quality by concentrating the radar beam precisely within the safety zone boundaries. Instead of uniform wide-area illumination, the system directs energy only where needed - specifically within the defined safety zone around the object - reducing waste while maintaining complete coverage of the monitoring area.
Solution Approach 2:
The beam width and direction are dynamically adjusted to match the safety zone dimensions and position. As the object moves or the safety zone boundaries change, the radar illumination pattern adapts accordingly, ensuring optimal energy utilization while maintaining complete safety zone coverage.
3Reliability
If the radar signal direction is continuously adjusted to track moving objects, then complete safety zone illumination is achieved, but the response time increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating or anticipating the required beam direction based on object movement trends. The control system prepares adjustment commands in advance, reducing the actual response time when beam direction changes are needed to maintain safety zone illumination.
Solution Approach 2:
The patent maintains continuous useful action by ensuring the radar beam is always properly positioned within the safety zone without interruption. The beam adjustment process is optimized to be continuous and smooth, avoiding delays while tracking moving objects and maintaining complete safety zone coverage throughout the monitoring period.
