Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the UAV follows the initial flight plan to inspect the flare stack, then inspection coverage is improved, but thermal damage risk increases
Solution Approach 1:
The flight plan is made dynamic by continuously adjusting the UAV's trajectory in real-time based on thermal sensor data. The system transitions from a static pre-planned path to a dynamic adaptive path that responds to changing thermal conditions, allowing the UAV to maintain inspection quality while avoiding thermal damage zones.
Solution Approach 2:
The system implements feedback control by using thermal sensors to continuously monitor the thermal environment and automatically adjusting the flight plan based on this feedback. The thermal sensor data feeds back to the flight control system, which modifies the trajectory to maintain safe thermal conditions while preserving inspection objectives.
2Object-affected harmful factors
If the UAV deviates from the initial flight plan to avoid thermal damage, then thermal damage risk is reduced, but inspection coverage may be compromised
Solution Approach 1:
The system dynamically adjusts the flight trajectory by calculating alternative paths that maintain required inspection coverage while avoiding thermal damage zones. The dynamic path planning algorithm continuously evaluates multiple potential trajectories and selects the optimal path that balances inspection quality with thermal safety.
Solution Approach 2:
The system changes flight parameters such as altitude, speed, and horizontal position in response to thermal conditions. By adjusting these parameters dynamically, the UAV can maintain effective inspection distances and angles while staying outside thermal damage zones, preserving inspection coverage without compromising safety.
3Manufacturing precision
If human inspectors are used to examine dangerous structures, then inspection quality is improved, but human safety risk increases
Solution Approach 1:
The UAV performs self-service inspection by autonomously navigating, collecting sensor data, and transmitting information without human presence in dangerous zones. The system uses onboard sensors, processors, and communication equipment to independently complete the inspection task, eliminating the need for human inspectors to physically approach hazardous structures.
Solution Approach 2:
The patent replaces the mechanical system of human inspectors with an automated UAV system equipped with sensors and processing equipment. This substitution transfers the inspection function from human operators to an autonomous robotic platform, maintaining inspection quality while eliminating human exposure to thermal and other hazards.

AI summary
In some implementations, a UAV flight system can dynamically adjust UAV flight operations based on thermal sensor data. For example, the flight system can determine an initial flight plan for inspecting a flare stack and configure a UAV to perform an aerial inspection of the flare stack. Once airborne, the UAV can collect thermal sensor data and the flight system can automatically adjust the flight plan to avoid thermal damage to the UAV based on the thermal sensor data.
