Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gimbal angle is fixed during inspection operations, then the device complexity is reduced, but the shooting field of view cannot completely cover the inspection object leading to missed detection
Solution Approach 1:
The gimbal control method enables the inspection system to automatically adjust the gimbal angle based on real-time position information and pre-set inspection paths. The system self-regulates the observation direction without manual intervention, allowing the shooting field of view to dynamically adapt to different inspection objects and ensure complete coverage throughout the inspection process
Solution Approach 2:
The patent transforms the fixed gimbal angle into a dynamic parameter that automatically adjusts during flight. By calculating the required gimbal angle based on current position, inspection path, and target coordinates, the system ensures the observation direction continuously adapts to maintain optimal viewing angles and complete coverage of inspection objects
2Productivity
If the gimbal angle is manually set during inspection, then the shooting field of view can be adjusted, but the workload of editing increases and inspection efficiency decreases
Solution Approach 1:
The system automatically calculates and adjusts gimbal angles based on pre-set inspection paths and real-time position data. The automatic control algorithm eliminates the need for manual angle setting by operators, reducing workload while maintaining precise observation direction control throughout the inspection process
Solution Approach 2:
The gimbal control method implements real-time feedback by continuously monitoring the UAV's position information and automatically adjusting the gimbal angle accordingly. The system compares current position with the inspection path and dynamically modifies the observation direction to ensure complete coverage, eliminating manual intervention and improving inspection efficiency
3Reliability
If the gimbal is fixedly directed to a certain direction, then the device complexity is reduced, but the observation direction cannot be automatically adjusted leading to missed detection
Solution Approach 1:
The patent converts the static gimbal direction into a dynamic parameter that automatically adjusts during flight operations. The control algorithm calculates the required gimbal angle based on real-time position information, inspection path coordinates, and target location, enabling the observation direction to continuously adapt and ensure complete inspection coverage
Solution Approach 2:
The system enables automatic gimbal control where the UAV autonomously adjusts its observation direction based on pre-set inspection paths and real-time position data. The automatic control mechanism eliminates the need for manual angle setting and ensures the shooting field of view consistently covers the inspection object throughout the flight
