Hinge Lock Integrating Security with Pivot Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and cabinet locks are difficult to install and do not provide adequate security while being easy to use.
Innovation Solution
A sleeve-shaped lock designed to fit around the pivot pin of a hinge, featuring a groove and a cap that applies pressure to the hinge connectors, preventing movement and requiring no additional installation steps beyond sliding onto the pivot pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locks (deadbolt, spring lock, security chain) are installed, then security is provided, but installation becomes difficult and complex
Solution Approach 1:
The invention extracts the locking function from complex conventional lock mechanisms and relocates it to the hinge itself. The hinge lock integrates the locking mechanism directly into the hinge assembly, eliminating the need for separate deadbolts, spring locks, or security chains, thereby simplifying installation while maintaining security.
Solution Approach 2:
The hinge serves multiple functions: it enables door movement and simultaneously provides security through the integrated lock mechanism. The same hinge structure that allows the door to open and close also contains the locking components, making the hinge a multi-functional element that reduces overall system complexity.
2Reliability
If child safety locks with bendable rods or electromagnetic mechanisms are used, then security is provided, but installation becomes difficult
Solution Approach 1:
The invention removes the complex installation requirements of child safety locks by integrating the locking mechanism into the hinge. Instead of requiring separate installation of bendable rods or electromagnetic devices, the security feature is built into the hinge structure itself, simplifying installation to merely mounting the hinge.
Solution Approach 2:
The invention merges the child safety lock functionality with the hinge mechanism. The locking components are combined with the hinge assembly, creating a unified structure that provides both the structural function of the hinge and the security function of the child safety lock without requiring separate installation steps.
3Reliability
If the lock restrains hinge movement effectively, then security is enhanced, but the lock structure becomes more complex
Solution Approach 1:
The invention combines the lock structure with the hinge assembly, merging two functional elements into one integrated unit. The locking components are incorporated within the hinge structure itself, eliminating the need for separate lock mechanisms and reducing overall structural complexity while maintaining effective restraint of hinge movement.
Solution Approach 2:
The hinge assembly serves dual purposes: enabling door movement and providing security through the integrated lock. By making the hinge multi-functional, the invention avoids adding separate lock structures, thereby enhancing security without proportionally increasing structural complexity.

AI summary
A security lock that retrains movement of a hinge is described. A locking system that includes a hinge that includes a first connector, a second connector and a pivot pin, the first connector pivotable relative to the second connector around the pivot pin, and a lock configured to be positioned over the pivot pin to restrain movement of the first connector is described.
