Single-Housing Electronic Locker Lock with Integrated Mechanical Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an electronic lock that is inexpensive, versatile, modular, easy to program, and user-friendly, particularly for lockers with standard three-hole door prep layouts, offering opposite-hand use and replacing traditional keyed or combination locks.
Innovation Solution
A compact electronic lock with a single housing containing all electronics on the front side of the locker door, featuring a keypad for code entry, a driver extending to the back to engage a mechanical latch or deadbolt, and a manual or motorized mechanism for operation, with a battery compartment accessible from the exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard two-housing electronic lock system is used, then security and electronic functionality are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the electronic lock housing and mechanical latch housing into a single integrated unit. The electronic components (keypad, circuit board, battery) are housed in one housing that directly engages with the latch mechanism, eliminating the need for separate front and back housings connected through door prep holes. This integration reduces installation complexity while maintaining security functionality.
2Reliability
If an electronic lock with keypad and electromagnetic latch is used, then security is improved, but ease of manufacture and cost increase
Solution Approach 1:
The patent replaces complex electromagnetic latch mechanisms with a simpler mechanical latch system that is directly actuated by the electronic motor. Instead of using electromagnetic fields to retract the latch, a small motor rotates a driver that mechanically moves the latch bolt. This substitution reduces manufacturing complexity and cost while maintaining electronic control functionality.
3Ease of manufacture
If a compact single-housing design is used, then ease of installation and cost are improved, but space for electronic components and mechanical features is reduced
Solution Approach 1:
The patent nests the electronic components (circuit board, keypad, battery compartment) within the single housing structure, arranging them in a compact configuration. The mechanical latch and driver mechanisms are integrated into the same housing volume, with components arranged concentrically and radially to maximize space utilization. This nesting approach allows all necessary components to fit within a compact single-unit design that maintains ease of installation.
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
The solution provides a low-power, easily installed electronic lock that is convenient to use, replacing traditional locks with enhanced security and versatility for various standard designs and user preferences.
Implementation Method 1
The latch device is moved to the retracted position by an electromagnetic or motorized mechanism in the outside housing
Implementation Method 2
The latch device is moved to the retracted position by an electromagnetic or motorized mechanism in the outside housing

AI summary
A locker lock fits a standard locker door three-hole door prep, with all electronics contained in a single housing mounted on the front of the locker door and a latch device behind the locker door. The locker lock preferably includes a keypad to allow rotation of a handle or knob, and also includes a manager's override and power jump terminal.
