Locker Lock Assembly Multipoint Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current evidence lockers, both keyed and keyless, require improvements in design for efficient manufacturing without compromising performance, particularly in ensuring restricted access and tamper-proof mechanisms.
Innovation Solution
A locker design featuring a storage member with a front access opening and a lock assembly that includes movable locking members, actuated by an operator, to securely close the front door, and an alternate embodiment with a keyed mechanism requiring a key for access, both ensuring secure storage through multipoint locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keyed or keyless locking mechanisms are used in evidence lockers, then access control and security are maintained, but manufacturing complexity and time increase
Solution Approach 1:
The locking mechanism is divided into modular components: a lock body assembly that can be separately manufactured and then integrated into the locker frame. This segmentation allows parallel manufacturing of different parts, reducing overall production time while maintaining the secure locking function through the modular assembly process
Solution Approach 2:
The lock body assembly is designed as a universal component that can be applied to different locker configurations and models. This multi-functional design allows the same locking mechanism to serve various security requirements across different evidence locker types, simplifying manufacturing by using standardized parts rather than custom-designed locks for each application
2Reliability
If traditional locking mechanisms are used, then security functionality is achieved, but the number of parts and assembly complexity increase
Solution Approach 1:
Multiple traditional locking components are merged into a single integrated lock body assembly. This consolidation combines what would traditionally be separate parts (locking bolts, actuation mechanisms, mounting structures) into one unified component, reducing the total number of parts while maintaining all necessary locking functionalities through integrated design
3Reliability
If conventional locking mechanisms are used, then access restriction is achieved, but manufacturing time and cost increase
Solution Approach 1:
The lock body assembly is pre-assembled and pre-tested as a complete functional unit before being installed into the locker frame. This preliminary assembly action allows the locking mechanism to be manufactured and validated independently, reducing on-site assembly time and enabling parallel production processes that overall reduce manufacturing time while ensuring the access restriction capability is fully functional

AI summary
A locker that may either be opened in a keyed or keyless manner includes a locking mechanism formed predominantly of sheet components. The locking mechanism is designed to be carried by the frame of the locker, and is particularly suited to enable the locker to be used as an evidence locker or similar restricted access storage compartment. Various spring biases are used to force the locking mechanism to a locked position when the locking mechanism is appropriately triggered, such as by a pushbutton. The locking mechanism is designed to be substantially tamper proof and cannot be reset to an unlocked position without a key, if equipped, or access to a lock resetting lever arm that is only accessible through a rear opening of the locker.
