Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UAV flies close to the high-speed railway for monitoring, then the monitoring quality and image clarity improve, but the airflow interference increases causing flight instability
Solution Approach 1:
The patent applies preliminary anti-action by pre-equipping the UAV with airflow shielding structures (transparent shielding plates) and electromagnetic shielding materials before entering the interference zone. These shielding components are installed in advance to counteract the anticipated airflow and electromagnetic field interference from high-speed trains, allowing the UAV to maintain stable flight and capture clear images while flying close to the railway without being severely affected by the interference.
2Ease of operation
If the UAV uses remote-control signaling for operation, then the ease of operation improves, but the electromagnetic field interference disrupts the signal transmission
Solution Approach 1:
The patent introduces an intermediary approach by equipping the UAV with electromagnetic shielding materials and structures that act as a barrier between the remote control signals and the strong electromagnetic fields generated by high-speed trains. This shielding intermediary protects the signal transmission, allowing remote control operation to remain effective despite the harsh electromagnetic environment near the railway.
3Productivity
If the UAV increases speed to reduce monitoring time, then the productivity improves, but the airflow interference from high-speed trains increases
Solution Approach 1:
The patent applies dynamics by making the UAV's speed adjustable and adaptive rather than fixed. The UAV can dynamically adjust its flight speed based on real-time conditions: flying at higher speeds when away from trains to maintain productivity, and slowing down or adjusting its flight path when detecting approaching trains to minimize airflow interference. This dynamic speed control allows the UAV to optimize both monitoring efficiency and flight stability in varying operational conditions.
