Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing unmanned aerial vehicle (UAV) systems, as disclosed in PTL 1, lack improvements in safety and efficiency during flight operations.
Innovation Solution
A lifting system comprising an unmanned aerial vehicle (UAV), a first device attachable to and detachable from the UAV, a first wire connecting the first device and the UAV, a first reel for reeling in the first wire, a second device attachable to and detachable from a package, a second wire connecting the first device and the second device, a second reel for reeling in the second wire, and a controller that manages the detachment and reeling of these components when the UAV is in a separated position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UAV maintains continuous connection to ground control stations via wires, then communication reliability is improved, but the risk of accidents and operational flexibility deteriorate
Solution Approach 1:
The system divides the connection into multiple independent wire segments (first wire between UAV and first device, second wire between first device and second device). Each wire can be independently managed and reeled in, allowing the system to maintain communication reliability through multiple pathways while reducing the harmful effect of a single point of failure or entanglement accident.
2Ease of operation
If the UAV operates independently without wire management systems, then operational flexibility is improved, but safety and control precision deteriorate
Solution Approach 1:
The system employs self-service mechanisms where the reels automatically reel in the wires when the UAV detaches or when wire length needs to be reduced. The controller autonomously manages the wire reeling operations based on UAV position and status, maintaining safety and control precision while allowing the UAV operational flexibility to detach and reattach as needed.
3Ease of operation
If the wire length is increased to allow greater UAV movement range, then operational flexibility is improved, but the risk of wire entanglement and accidents increases
Solution Approach 1:
The system dynamically adjusts the wire length configuration through the reel mechanism. The wires can be extended when the UAV needs to move to a new position and reeled in when the UAV returns or when proximity is required. This dynamic wire management allows the system to achieve greater movement range while minimizing wire entanglement risk through controlled wire length adjustment.

AI summary
A lifting system includes an unmanned aerial vehicle, a thruster device, a first wire, a first reel, a second thruster device, a second wire, a second reel, and a controller. When the unmanned aerial vehicle is in a position separated from the ground, the controller detaches the first thruster device and the second thruster device from the unmanned aerial vehicle, causes the first reel to reel out the first wire, detaches the second thruster device from the first thruster device, and causes the second reel to reel out the second wire.
