Automatic Container Chassis Latch for Reliable Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional latching devices for container chassis are manually operated, leading to improper locking or unlocking, which can result in improper loading/unloading and potential container shifting or loss during transport.
Innovation Solution
A container retention device with a housing, actuator, link assemblies, and a locking member that automatically secures the container to the chassis upon placement, utilizing a linkage mechanism and actuation device to ensure securement without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of latching devices is used, then the device complexity is reduced, but the reliability of proper locking/unlocking deteriorates
Solution Approach 1:
The latching system automatically secures the container to the chassis without manual intervention. The actuator detects when the container is properly positioned and automatically actuates the locking mechanism, eliminating the need for manual operation while ensuring reliable locking.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated actuation system that uses sensors and automated mechanisms to detect container placement and trigger the locking sequence, improving reliability while managing complexity through automation.
2Reliability
If manual operation of latching devices is used, then the ease of operation is improved, but the reliability of securement deteriorates
Solution Approach 1:
The system performs the securement function automatically without requiring operator intervention. The actuator monitors container placement and autonomously executes the locking sequence, ensuring reliable securement while simplifying the operator's task to merely positioning the container.
3Reliability
If automatic latching system is implemented, then the reliability of securement is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an automated actuation system with sensors and control mechanisms to replace manual operation. This substitution improves securement reliability by eliminating human error while managing the increased complexity through integrated automated control.
Solution Approach 2:
The actuator includes sensing capabilities that detect container placement and provide feedback to the control system. This feedback mechanism ensures reliable securement by confirming proper positioning before actuating the locking mechanism, managing complexity through intelligent control.
4Productivity
If manual locking/unlocking is used, then the ease of operation is improved, but the productivity of loading/unloading deteriorates
Solution Approach 1:
The automatic latching system performs the securement function autonomously, eliminating the time required for manual locking operations. The actuator automatically detects container placement and executes locking, significantly improving loading/unloading productivity while requiring minimal operator action.

AI summary
A container retention device comprises a housing and an actuator having a first portion disposed in the housing and a second portion movable between a first position inside the housing to a second position outside the housing. The device further comprises a first link assembly in the housing engageable by the first portion of the actuator and movable in response to movement of the second portion between the first and second positions. Also, a second link assembly is disposed in the housing having a third portion engageable by the first link, a fourth portion, and a fifth portion disposed between the third portion and the fourth portion wherein the third portion and the fourth portion are rotatable about the fifth portion in response to movement of the first link assembly. A locking member is extendable outside the housing in response to movement of the second portion to the first position. A container retention method is also disclosed.
