Automatic Locking Mechanism for Cargo Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual operation of twist locks for connecting cargo containers or equipment modules to mounting surfaces is time-consuming, dangerous, and results in incomplete interconnection, especially when containers are stacked closely, posing a security risk and accessibility issues.
Innovation Solution
An automatic locking mechanism with a housing and elongated shaft element that can be displaced and rotated to engage with standard ISO container corners, using hydraulic, electrical, or mechanical drive means for secure and stable interconnection, preventing unintentional movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of twist locks is used to connect containers to mounting surfaces, then the operator can control the locking process, but the operation is time-consuming and dangerous due to heavy container weights
Solution Approach 1:
The locking mechanism performs the locking operation automatically without requiring manual intervention. The system uses the container's own weight and positioning to trigger the locking action, where the container essentially locks itself into place through the automatic detection of correct positioning and subsequent engagement of the locking elements.
Solution Approach 2:
The patent replaces the manual mechanical operation of twist locks with an automated system that uses sensors to detect container positioning and automatically actuates the locking mechanism through electrical or electronic control systems, eliminating the need for manual mechanical manipulation.
2Productivity
If containers are arranged in stacks closely positioned to maximize space utilization, then space efficiency is improved, but operators cannot access all twist locks for complete interconnection
Solution Approach 1:
The automatic locking mechanism eliminates the need for operator access to tighten locks. The system automatically detects when containers are correctly positioned and engages the locking elements without requiring any manual intervention, making the locking process independent of operator accessibility.
Solution Approach 2:
The patent introduces a new dimension of operation by moving from manual ground-level access to automated remote operation. The locking mechanism is actuated from a distance or automatically, changing the operational dimension from physical proximity to remote or automated control, thereby solving the accessibility problem.
3Reliability
If manual locking operations are performed on heavily stacked containers, then some locks can be secured, but the operator faces safety risks and cannot reach all locking points
Solution Approach 1:
The locking system performs the interconnection function automatically without human involvement. The mechanism detects container positioning and executes the locking sequence autonomously, ensuring complete interconnection of all locking points while eliminating operator exposure to safety risks associated with heavy container stacks.
Solution Approach 2:
The patent introduces an automated control system as an intermediary between the container positioning and the locking action. This intermediary system uses sensors and actuators to mediate the locking process, ensuring that all locks are secured completely and reliably without requiring direct human intervention in the dangerous stacking environment.
