Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the distance between UAV location and no-fly area is used to determine relative position, then the control method is simple, but the position determination accuracy is insufficient leading to potential unsafe accidents
Solution Approach 1:
The spatial set is segmented into multiple discrete regions (first area, second area, third area) with different safety levels. Instead of treating the space as continuous, the method divides it into zones where each zone has specific control requirements, enabling more precise position determination while maintaining manageable control logic through regional classification
Solution Approach 2:
The patent transitions from one-dimensional distance measurement to two-dimensional spatial region classification. By introducing area-based positioning with multiple zones radiating from the no-fly area, the system achieves higher position determination accuracy by utilizing angular and radial dimensions simultaneously, rather than relying solely on radial distance
2Measurement precision
If comprehensive area division and relative position calculation are implemented, then position determination accuracy is improved, but the computational complexity increases
Solution Approach 1:
The control device pre-establishes the spatial set, divides it into multiple regions, and sets no-fly areas before operation begins. This preliminary configuration allows the system to avoid real-time complex calculations by simply determining which pre-defined region the UAV occupies, significantly reducing computation time while maintaining high position determination accuracy
Solution Approach 2:
The system dynamically adjusts control strategies based on the UAV's real-time position within different regions. Rather than using static control parameters, the method adapts control actions according to which pre-defined region the UAV is in, enabling efficient real-time control with reduced computational burden while maintaining high positioning accuracy
