Slam Latch Mechanism for Quick Container Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage container latching mechanisms require manual manipulation of handles or knobs to lock and unlock, which can be inconvenient, especially in emergency situations where quick access is necessary, and they often lack sufficient security features.
Innovation Solution
A slam latch mechanism using a spring loading mechanism with rotatably engaged rods and strikers, allowing the container or tonneau cover to be secured with a single motion by slamming it shut, eliminating the need for direct manipulation of the locking mechanism and providing enhanced security through multiple contact points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual handles or knobs are used for locking, then the mechanism is simple to manufacture, but it requires time-consuming manual manipulation and lacks quick access capability
Solution Approach 1:
The slam latch mechanism automatically latches when the container is closed by simply slamming it shut, without requiring manual manipulation of handles or knobs. The spring-loaded rod automatically engages with the striker upon closure, enabling self-service operation that achieves both quick closure and automatic locking.
2Reliability
If traditional locking mechanisms are used, then the device complexity is low, but the security against tampering is insufficient
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a spring-loaded rod with offset, multiple strikers positioned at different locations, and a paddle handle. This segmentation allows the system to achieve enhanced security through multiple contact points while maintaining relative simplicity in each individual component's design.
Solution Approach 2:
The invention adds a spatial dimension to the locking mechanism by positioning multiple strikers at different locations around the container perimeter. The rod engages with these strikers at various points, creating a multi-point locking system that enhances security without requiring complex mechanical structures in any single location.
3Reliability
If multiple contact points are used for locking, then security is enhanced, but the mechanism complexity increases
Solution Approach 1:
The single rod serves multiple functions: it engages with multiple strikers at different locations, provides the locking action, and can be actuated by a simple paddle handle. This multi-functionality allows the system to achieve enhanced security through multiple contact points without proportionally increasing the number of separate components, as one rod performs the work of what would traditionally require multiple locking elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and secure closure of storage containers and tonneau covers with a single hand motion, ensuring immediate access without keys and providing increased security against tampering and unauthorized access.
Implementation Method 1
A lock comprises a handle and a spring loading mechanism, wherein the handle is rotatably engaged to the spring loading mechanism
Implementation Method 2
A rod is in a rotational engagement with the lock, and the rod having an offset that interacts with the striker in a locking relationship

AI summary
A slam type locking mechanism is described. The locking mechanism allows a storage container with the locking mechanism to be slammed shut in a single motion. The operator may slam the lid or door to the container using a single hand that is only pressing or pushing the lid or door closed. The slam type locking mechanism includes a lock having a lock housing, a handle, and a spring loading mechanism. The handle is rotatably engaged to the spring loading mechanism. The rods are in a rotational engagement with the lock, wherein the rods have an offset that interacts with a striker on the container or lid in a locking relationship.
