Aircraft Cargo Loading Device With Spring-Biased Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cargo loading/unloading systems for aircraft are inefficient for packages with large weight and volume, as they struggle to securely transport and release such items without human intervention, leading to delays and increased costs due to timing constraints.
Innovation Solution
A package loading/unloading device featuring a base with a tongue, a rod with a loop, and spring-biased arms that securely attach to the package during flight and release it upon landing, using a cable and a tape to ensure secure transport and automatic unloading without human interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a racket with cable loop system is used for package delivery, then packages with small weight and volume can be securely transported, but packages with large weight and volume cannot be easily freed from the racket
Solution Approach 1:
The invention divides the attachment system into two independent parts: a base that remains on the aircraft and a movable arm that extends to the package. This segmentation allows the system to handle various package sizes by adjusting the arm's position and length, resolving the contradiction between secure attachment and adaptability to different package dimensions.
Solution Approach 2:
The movable arm can dynamically adjust its position and orientation based on package characteristics. The arm pivots on the base and can be positioned at different angles and distances, enabling the system to adapt to packages of varying weight and volume while maintaining secure attachment through the cable mechanism.
2Reliability
If manual unloading is required at the destination, then package security is maintained during transport, but delivery efficiency is reduced due to waiting time for personnel arrival
Solution Approach 1:
The system enables self-service unloading by using the package's own weight to automatically trigger the release mechanism. When the aircraft lands and the cable loses tension, the spring-loaded arm automatically returns to its initial position, freeing the package without requiring manual intervention, thus improving delivery efficiency while maintaining security during transport.
Solution Approach 2:
The spring mechanism is pre-loaded during manufacturing to automatically trigger package release when the aircraft lands. This preliminary setup eliminates the need for manual unloading operations at the destination, as the system is already configured to automatically perform the release action based on the landing event.
3Reliability
If the aircraft waits for personnel to arrive at the agreed location, then package security is ensured, but time is wasted waiting for personnel arrival
Solution Approach 1:
The automatic release system eliminates the need for personnel to be present at the agreed location. The system performs the unloading function autonomously based on the aircraft's landing event, completely eliminating waiting time for personnel arrival while maintaining package security during the transport phase.
Solution Approach 2:
The invention replaces the manual mechanical unloading process with an automated spring-loaded mechanical system that triggers automatically upon landing. This substitution eliminates the need for human intervention in the unloading process, removing the time loss associated with waiting for personnel arrival.

AI summary
A cargo loading/unloading device for an aircraft includes a base, two arms pivotally movable on top of the base and a push rod pivotally connected to the base and sandwiched between the two arms. A cable extends through the push rod and forms into a loop after passing through a bottom end of the push rod so that a package is able to be securely transported with the cooperation of the push rod and the two arms and be released onto the arms when the package weight is not functioning.
