Security Pin With Asymmetric Profile For Container Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container cover/door locking systems lack high security measures to prevent unauthorized access and forceful rotation, as well as protection against direct abuse to the locking mechanism.
Innovation Solution
A security pin with a metal sleeve and non-cylindrical profile, encased in a metal collar, that requires a designated driver for rotation and is protected by a metal barrier to prevent unauthorized access and direct contact with the locking mechanism, ensuring smooth operation and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard locking mechanism is used, then ease of operation is maintained, but security against unauthorized access and forceful rotation is insufficient
Solution Approach 1:
A security pin with a specially patterned head acts as an intermediary between the driver and the locking mechanism. The pin head requires a matching patterned driver for rotation, while the pin shaft interfaces with the locking mechanism through a non-cylindrical profile. This intermediary component provides security without complicating the overall operation.
Solution Approach 2:
The security pin head features an asymmetric pattern (such as stars, circles, or squares) that must match the driver pattern. This asymmetric design prevents unauthorized rotation while allowing legitimate users with the correct driver to operate the lock easily. The non-cylindrical shaft profile also employs asymmetry to ensure proper alignment and operation.
2Reliability
If the security pin directly contacts the locking mechanism, then operational simplicity is maintained, but vulnerability to direct abuse and damage increases
Solution Approach 1:
The security pin is nested within a metal sleeve or collar that provides protective structure. The pin shaft extends through the locking mechanism body without direct contact between the pin head and the locking mechanism components. This nested arrangement protects the locking mechanism from direct abuse while maintaining operational functionality.
Solution Approach 2:
The metal barrier or locking mechanism body acts as an intermediary between the security pin and external forces. This intermediary structure prevents direct transmission of abusive forces to the pin head and locking components, while still allowing the pin shaft to rotate and operate the latch through its non-cylindrical profile interface.
3Reliability
If the pin head is exposed without protection, then ease of access is maintained, but vulnerability to forceful rotation and damage increases
Solution Approach 1:
The pin head is nested within a metal sleeve or collar that provides protective structure. The pin shaft extends through the locking mechanism body without direct contact between the pin head and the locking mechanism components. This nested arrangement protects the locking mechanism from direct abuse while maintaining operational functionality.

AI summary
Container cover/door with high security locking system comprises a metal cover/door having a first through opening surrounded by a first metal sleeve or collar extending inwardly from the outer surface of the cover/door. Fixedly attached to the inner surface of the cover/door is a metal bracket having a second through opening surrounded by a second metal sleeve or collar that extends outwardly within the first collar. The locking system comprises a locking mechanism including a spring loaded latch contained within a housing mounted to an inner surface of the metal bracket, and a security pin having a pin head that is encased within the second collar with a close tolerance therebetween, and a pin shaft of a smaller diameter than the pin head that extends inwardly from the pin head through an opening in the locking mechanism.
