Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual operation is used for UAV control, then operating costs and liability are reduced, but automation level and operational efficiency deteriorate
Solution Approach 1:
The patent integrates multiple sensor types (cameras, LIDAR, GPS, accelerometers, gyroscopes) into a unified autonomous navigation system that performs multiple functions: obstacle detection, position estimation, motion planning, and stabilization. This multi-functional approach enables full autonomous operation while managing system complexity through integrated architecture.
2Extent of automation
If vision-based position estimation is used, then navigation capability is improved, but measurement precision deteriorates
Solution Approach 1:
The patent combines vision-based estimation with data from LIDAR, GPS, accelerometers, and gyroscopes to create a fused navigation system. This integration merges the advantages of visual context understanding with the precision of other sensors, achieving both automated navigation and accurate position/motion estimation through sensor fusion algorithms.
3Extent of automation
If image capture devices are added for autonomous navigation, then navigation capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the autonomous navigation system into distinct functional modules: obstacle detection module (cameras, LIDAR), position estimation module (GPS, visual odometry), motion planning module, and stabilization module (gyroscopes, accelerometers). This segmentation allows each sensor type to be optimized for its specific function while reducing overall system complexity through modular architecture.
4Reliability
If multiple image capture devices are used for obstacle avoidance, then safety is improved, but device complexity increases
Solution Approach 1:
The patent positions image capture devices at specific locations on the UAV (front, rear, side-facing cameras) to optimize obstacle detection in critical directions. This local quality approach places sensors where they are most needed for safety-critical functions rather than uniformly distributing all sensor types, improving obstacle avoidance reliability while managing complexity through strategic placement.
