Drone Delivery Wire Guide and Auto-Separation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional delivery drones using wire lifting devices require manual unloading and are prone to wire shaking due to rotor wind, complicating the loading and unloading process and increasing the risk of accidents.
Innovation Solution
A delivered article loading apparatus for drones featuring a lifting body and a disposable hanging body that automatically separates from the wire upon ground contact, combined with a guide member that protects and stabilizes the wire to prevent shaking from rotor wind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire lifting device is used to support delivered articles, then the drone can perform delivery operations, but the wire is shaken by rotor wind causing accidents and operational disturbances
Solution Approach 1:
The patent introduces a guide member as an intermediary component between the rotor and the wire. This guide member redirects the wind flow from the rotor away from the wire, preventing the wire from being shaken while maintaining the lifting function. The guide member acts as a mediator that manages the interaction between the rotor wind and the wire.
2Ease of operation
If a hanging tool is used to support delivered articles, then loading and unloading operations can be performed, but manual separation is required increasing operational complexity
Solution Approach 1:
The patent implements a self-service mechanism where the wire automatically detaches from the hanging tool when the delivered article contacts the ground. The system uses the weight and position of the delivered article to trigger automatic separation, eliminating the need for manual intervention. This self-service feature enhances both automation and ease of operation.

AI summary
Disclosed is a delivered article loading apparatus, which is mounted to a lifting wire installed at the drone to be capable of lifting. The delivered article loading apparatus includes a lifting body installed at a lower end of the lifting wire; and a disposable hanging body coupled to be selectively connected to or separated from the lifting body and having a hooking unit at a lower portion thereof, wherein the lifting body and the disposable hanging body are automatically separated by a mechanical or electromagnetic interaction therebetween.
