UAV Cargo Release Control Using Post-Detachment Load Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts face issues with appropriate cargo release during automated transport, as the cargo may get caught on the aircraft, leading to unsuccessful detachment and potential safety hazards.
Innovation Solution
A control method is implemented that includes detachment control, load detection, and subsequent aircraft control based on the mechanical load detected, allowing the aircraft to take appropriate actions such as takeoff, hovering, or landing depending on the success or failure of cargo detachment, ensuring safety and accurate movement.

Engineering Contradiction Analysis
1Productivity
If automated detachment control is performed, then operational efficiency is improved, but cargo may not be appropriately released due to catching on aircraft parts
Solution Approach 1:
The patent implements a feedback mechanism by detecting mechanical load on the support portion or connecting portion after detachment control is performed. Based on the detected load status, the system determines whether cargo detachment was successful or failed, and automatically adjusts subsequent aircraft movement accordingly. This closed-loop feedback ensures reliable cargo release while maintaining automated operation efficiency.
2Productivity
If the aircraft continues movement after detachment control, then operational continuity is improved, but unsafe movement may occur if cargo detachment fails
Solution Approach 1:
The system uses mechanical load detection as feedback to determine cargo detachment status before allowing subsequent aircraft movement. If detachment is confirmed successful (load reduced to threshold or below), the aircraft proceeds with scheduled movement. If detachment fails (load remains above threshold), the aircraft restricts movement or hovers, preventing unsafe operation while maintaining operational continuity when conditions permit.
3Reliability
If the aircraft restricts movement after detachment control, then safety is improved, but operational efficiency deteriorates
Solution Approach 1:
The system implements conditional movement restriction based on real-time mechanical load feedback. Rather than universally restricting movement after detachment control, the system selectively restricts movement only when cargo detachment fails (load above threshold). When detachment succeeds (load at or below threshold), the aircraft continues scheduled operations without restriction. This feedback-based approach ensures safety while minimizing impact on operational efficiency.

AI summary
An UAV 1 performs a detachment control to detach a cargo supported by a support portion 117 or connected a connecting portion 118, and thereafter, performs a load detection process of detecting a mechanical load applied to the support portion 117 or the connecting portion 118. And then An UAV 1 performs different control according to the mechanical load, with respect to a movement of the UAV 1 after the detection of the mechanical load.
