Solution Approach 1:

The patent applies the dynamics principle by making the sunlight reflection plate adjustable in angle. The reflection plate can be tilted to different angles according to seasonal variations in sun altitude, allowing the system to adapt to changing conditions rather than being fixed. This resolves the contradiction by enabling the system to maintain high sunlight transfer efficiency across different seasons while keeping the adjustment mechanism relatively simple.

Solution Approach 2:

The patent applies parameter changes by varying the tilt angle of the reflection plate based on seasonal changes in sun altitude. The angle parameter is adjusted to match the meridian altitude of the sun at different times of year, ensuring optimal sunlight transfer efficiency. This allows the system to respond to environmental changes without complex restructuring.
