Cam Lock With Secondary Core Assembly For Code Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Combination locks are inconvenient when users forget the code, as they cannot be unlocked without destruction, leading to unnecessary costs for temporary locker users and managers.
Innovation Solution
A cam lock design featuring an inner and outer shell, main and secondary core assemblies, an identification assembly, and a tongue, allowing users to find the correct code by cooperating with the secondary core assembly using a key to unlock the secondary core, making the lock convenient for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a combination lock is used, then no keys are required and the lock is compact, but the lock cannot be unlocked if the code is forgotten without destruction
Solution Approach 1:
The lock is divided into two independent core assemblies: a main core assembly for normal combination lock operation, and a secondary core assembly for recovery when the code is forgotten. This segmentation allows the system to maintain keyless operation while providing a separate backup mechanism that doesn't require destruction to access.
Solution Approach 2:
A tongue mechanism acts as an intermediary between the two core assemblies. The tongue can be rotated by either the main core assembly (when code is known) or the secondary core assembly (when code is forgotten), translating both input methods into the same locking/unlocking action. This intermediary allows seamless switching between normal operation and recovery mode.
2Reliability
If the combination lock is destroyed to change the code, then the lock can be accessed, but costs are incurred for destruction and replacement
Solution Approach 1:
The secondary core assembly enables the lock to reset its own code without external intervention or destruction. When the code is forgotten, users can use a key to operate the secondary core assembly, which rotates the tongue to unlock the lock and allows access to reset the main combination. This self-service capability eliminates the need for costly professional intervention or lock replacement.
Solution Approach 2:
Instead of discarding the entire lock when the code is forgotten, the system recovers functionality by activating the secondary core assembly as a backup mechanism. The secondary core assembly serves as a recoverable resource that can be used to regain access and reset the primary combination, preserving the main lock body and avoiding replacement costs.
3Device complexity
If a simple combination lock structure is used, then the lock is compact and easy to manufacture, but there is no way to recover the code when forgotten
Solution Approach 1:
The patent combines two core assemblies (main and secondary) and a tongue mechanism into a single integrated lock body. Despite the increased functionality, the overall structure remains compact because both core assemblies share the same housing and operate through the common tongue mechanism. This merging allows code recovery capability to be added without significantly increasing the lock's size or manufacturing complexity.

AI summary
The main objective of the present invention is to provide a cam lock that allows the user to find the correct code when forgetting. The cam lock has an inner shell, an outer shell, a main core assembly, a secondary core assembly, a tongue and an identification assembly. A cover of the outer shell and the inner shell are secured to each other and are mounted rotatably with the rear casing of the outer shell. The main and secondary core assemblies are mounted in the inner shell. Either the main and secondary core assemblies is unlocked, the tongue is rotatable. The identification assembly cooperates with the secondary core assembly to find the code via unlocking the secondary core assembly. Therefore, the cam lock is convenient for use.
