Automatic Front Pin Latching System for Container Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional latching systems for securing containers to chassis require manual operation, leading to potential improper locking or unlocking, which can result in improper unloading or shifting during transport.
Innovation Solution
A front pin latching arrangement with automatic securement systems, including first and second latching systems and an interlock assembly, that automatically secure the container to the chassis by vertically moving a shelf and horizontally moving a pin through adjacent openings, ensuring fail-safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual latching systems are used, then the structure is simple, but the reliability of securement is reduced due to improper operation
Solution Approach 1:
The latching system automatically secures the container to the chassis without requiring manual operation. The system uses the weight of the container itself to trigger the latching mechanism, making the system self-actuating and eliminating human error in the latching process.
Solution Approach 2:
The patent replaces manual mechanical operation with an automatic mechanical system that uses springs and linkages to detect container placement and activate the latching mechanism, thereby improving reliability while maintaining mechanical simplicity.
2Ease of operation
If automatic latching systems are implemented, then operation reliability improves, but device complexity increases
Solution Approach 1:
The system automatically detects when a container is placed on the chassis and activates the latching mechanism without requiring operator intervention. The container's own weight triggers the actuation, making the system self-service and fully automated.
Solution Approach 2:
The latching mechanism is pre-positioned and spring-loaded, ready to engage automatically when the container is placed. The system performs the latching action in advance of any potential movement, ensuring securement is established before transport begins.
3Productivity
If manual latching is used, then the system is simple to operate, but productivity is reduced due to time-consuming manual intervention
Solution Approach 1:
The automatic latching system eliminates the time required for manual operation by using the container's placement and weight to automatically trigger the latching mechanism, significantly reducing the time needed to secure containers during loading operations.
Solution Approach 2:
The latching mechanism is pre-configured and spring-loaded to engage immediately upon container placement, eliminating delays associated with manual operation and accelerating the container securement process.
4Reliability
If conventional latching systems are used, then the structure is straightforward, but safety is compromised due to improper locking
Solution Approach 1:
The system automatically ensures proper locking by using the container's weight to trigger the latching mechanism, eliminating human error and ensuring consistent, safe securement without requiring complex additional safety features.
Solution Approach 2:
The latching system incorporates mechanical feedback through springs and linkages that detect whether the container is properly positioned and secured. The system provides tactile and visual feedback to confirm proper latching, ensuring safety without excessive complexity.

AI summary
A front pin arrangement for automatic securement of a container to a container chassis is provided. The front pin latching arrangement includes first and second latching systems disposed proximate two corners of a container chassis, wherein each of the first and second latching systems automatically secure the container to the container chassis. The front pin latching arrangement also includes an interlock assembly operably coupled to the first and second latching systems. The interlock assembly is configured to provide a fail-safe operation such that the first and second latching systems maintain securement of the container to the container chassis.
