Sensor-Activated Cargo Locking for Faster ULD Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft cargo handling systems require manual engagement and disengagement of lock mechanisms, which is labor-intensive and time-consuming.
Innovation Solution
An intelligent cargo handling system with automated locking mechanisms, featuring a drive assembly and sensor-controlled locking mechanism that automatically retains and releases unit load devices (ULDs) using a motor-driven pawl system, reducing the need for manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual engagement and disengagement of lock mechanisms is used, then the system structure remains simple, but labor intensity increases and time consumption increases
Solution Approach 1:
The locking mechanism automatically engages and disengages without requiring manual operation. The system uses sensors to detect the presence of unit load devices and automatically activates the drive assembly to lock or unlock the mechanisms, eliminating the need for manual labor while maintaining operational simplicity
Solution Approach 2:
The patent replaces manual mechanical operation with an automated system comprising sensors, a controller, and a motor-driven drive assembly. This substitution eliminates manual labor while introducing controlled complexity through electronic components that manage the locking mechanism

If automated locking mechanisms are implemented, then labor intensity decreases and productivity increases, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical operation with an automated system comprising sensors, a controller, and a motor-driven drive assembly. This substitution eliminates manual labor while introducing controlled complexity through electronic components that manage the locking mechanism
Solution Approach 2:
The system incorporates sensors that detect the presence and position of unit load devices, providing feedback to the controller. The controller uses this feedback to automatically activate or deactivate the drive assembly, ensuring the locking mechanism operates only when needed and maintains appropriate engagement states

AI summary
A cargo handling system (20) for restraining a unit load device includes a structural channel (22) having a hollow interior (24), and a locking mechanism (26) associated with the structural channel (22). The locking mechanism (26) is movable to engage the unit load device. A motor assembly (50) is coupled to the at least one locking mechanism (26). The motor assembly (50) is operable to automatically move the at least one locking mechanism (26) upon detection of the unit load device at or approaching a desired position adjacent the at least one locking mechanism (26).
