Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional route planning is used for UAV spray operations, then the operation route can be generated based on simple planar coverage algorithms, but the route lacks altitude information which affects safety and effectiveness when encountering three-dimensional terrain variations
Solution Approach 1:
The patent transforms the traditional two-dimensional route planning into three-dimensional route planning by incorporating altitude information into waypoints. The system obtains three-dimensional terrain data and generates operation routes that include vertical dimension adjustments, allowing the UAV to adapt to terrain variations such as hills and valleys while maintaining safe spray coverage.
2Productivity
If two-dimensional route planning is used, then the planning algorithm is simple and fast to execute, but the spray operation effectiveness is reduced due to inability to adapt to terrain variations
Solution Approach 1:
The patent implements dynamic route adjustment by incorporating real-time terrain data into the navigation system. The operation route is no longer a static two-dimensional path but a dynamic three-dimensional trajectory that automatically adjusts altitude based on terrain features, enabling the UAV to adapt to varying terrain conditions while maintaining operational efficiency.
3Reliability
If altitude information is added to waypoints, then the spray operation safety and effectiveness are improved, but the route planning complexity and computational requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-obtaining three-dimensional terrain data and pre-calculating the three-dimensional operation route before UAV execution. The system processes terrain information and generates the optimized 3D route in advance, reducing real-time computational burden during actual spray operations while ensuring safety and effectiveness.
