Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual control of UAV is used for solar panel inspection, then operator skill and experience can ensure high-quality image capture, but inspection process becomes labor-intensive and time-consuming
Solution Approach 1:
The UAV system performs self-positioning and self-capture operations through automatic control. The controller autonomously processes image data from sensors, determines optimal positioning, and triggers the camera without requiring continuous human intervention, enabling the system to serve itself during the inspection process
Solution Approach 2:
The patent replaces manual mechanical control with an automatic control system that uses sensor data processing and algorithmic decision-making. The controller substitutes human operator actions with automated navigation and image capture mechanisms, eliminating the need for skilled manual operation while maintaining inspection quality
2Reliability
If manual operation is used to fly UAV to fault sites, then operator can recognise and respond to faults, but latency is introduced due to human recognition and initialisation time
Solution Approach 1:
The system performs preliminary positioning and preparation actions automatically before fault detection is needed. The UAV is pre-programmed with navigation capabilities and can immediately respond to fault detections without waiting for human operator preparation, reducing the time loss associated with fault response
Solution Approach 2:
The automatic control system enables the UAV to independently respond to fault conditions by autonomously navigating to fault sites and capturing images without requiring human operator recognition or initialisation, eliminating the latency inherent in manual fault detection processes
3Reliability
If regular inspection rounds are scheduled with manual operation, then comprehensive coverage can be achieved, but constant operator monitoring is required
Solution Approach 1:
The UAV system performs self-monitoring and self-management during inspection rounds. The automatic control system independently manages navigation, positioning, and image capture sequences without requiring constant human supervision, enabling scheduled inspections to run autonomously while maintaining comprehensive coverage
Solution Approach 2:
The system incorporates feedback mechanisms where the controller continuously processes sensor data and adjusts operations accordingly. This automated feedback loop replaces the need for constant operator monitoring by providing real-time self-adjustment and verification of inspection quality

AI summary
A method for inspecting a solar panel of a solar power station is performed in a controller for an unmanned aerial vehicle, UAV, and includes the steps of: receiving an inspection request for a subset of the solar panels navigating, in a first stage, using radio signals, the UAV to an initial location in a vicinity of a particular solar panel of the subset of solar panels; positioning, in a second stage, the UAV using at least one near field sensor of the UAV; and capturing, using the infrared camera, an image of the particular solar panel.
