UAV Nest Docking and Winch Delivery for Precise Package Lowering

The patent applies beforehand cushioning by implementing a controlled descent mechanism that reduces the package's descent velocity before ground contact. The system uses a winch mechanism with variable speed control to gradually reduce the lowering speed, ensuring the package reaches the ground at a safe velocity that prevents impact damage while still maintaining efficient delivery timing.

The patent applies dynamics by implementing a variable velocity control system that adjusts the package lowering speed dynamically during descent. The system transitions from higher initial velocities to progressively lower velocities as the package approaches the ground, optimizing the balance between delivery speed and impact prevention through continuous velocity modulation rather than maintaining a constant low speed throughout the entire descent.

The patent applies self-service by implementing an autonomous landing system where the UAV independently tracks and lands on the moving target without requiring complex external control algorithms. The UAV uses onboard sensors and processors to autonomously calculate the moving target's trajectory, adjust its own flight path, and execute precise landing, thereby achieving high landing precision while maintaining relatively simple overall system architecture.

The patent applies segmentation by separating the battery charging function from the UAV's operational structure. The battery is designed as a modular component with integrated charging contacts that allow the battery to be charged independently while remaining connected to the UAV system. This segmentation enables the battery to be removed for dedicated charging without requiring UAV power loss or rebooting, as the charging process occurs autonomously at the battery level.

The patent applies self-service by implementing an autonomous charging system where the UAV automatically docks with the charging station and establishes electrical contact without operator intervention. The charging contacts are designed to engage automatically when the UAV lands on the charging pad, eliminating the need for manual cord attachment. This self-service mechanism maintains continuous power supply capability while significantly reducing operational complexity and material wear from repeated manual connections.
