Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual control of UAV is used for solar panel inspection, then high-quality image capture can be achieved, but inspection time increases and operator latency in fault detection occurs
Solution Approach 1:
The UAV is equipped with autonomous navigation capabilities using GPS coordinates and automated control systems that enable it to independently navigate to inspection locations, position itself, and capture images without continuous manual operator intervention. The system self-manages the inspection process while maintaining image quality through programmed positioning accuracy.
2Measurement precision
If manual control of UAV is used for solar panel inspection, then high-quality image capture can be achieved, but operator intervention is required continuously
Solution Approach 1:
The UAV system performs self-navigation using GPS coordinates, self-positioning at inspection points, and automated image capture sequences. The autonomous control system manages flight paths, hovering positions, and camera operation without requiring continuous manual input, thereby increasing automation while preserving image quality through programmed precision.
3Ease of operation
If UAV positioning is not precise, then automated control can be simplified, but image capture quality deteriorates
Solution Approach 1:
The UAV employs feedback mechanisms through near-field sensors that continuously monitor position relative to the solar panel and provide real-time data to the control system. This feedback enables automated adjustment of positioning to maintain optimal capture angles and distances, ensuring image quality while preserving automation through closed-loop control.
4Measurement precision
If UAV flies too close to solar panel for detailed inspection, then image quality improves, but UAV may shadow the panel affecting inspection accuracy
Solution Approach 1:
The system implements local quality optimization by adjusting UAV positioning based on the specific inspection requirements of each solar panel. The automated control system calculates optimal positions that balance proximity for detailed imaging with sufficient distance to avoid shadowing, creating locally optimized capture conditions for each panel while maintaining overall automation.

AI summary
It is presented a method for inspecting a solar panel of a solar power station. The method is performed in a controller for an unmanned aerial vehicle, UAV, and comprises 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 solarpanel.
