Replaceable Electronic Lock Core With Secure Retainment Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic locks face challenges in efficiently replacing the electronic lock core without replacing the entire lock, especially when physical security, cost, or logistical constraints are involved.
Innovation Solution
A system for replacing the electronic lock core within an electronic lock, featuring a retainment assembly with a screw, retainer ramp, and control lug that secures the core in place, using a screw guard magnetically engaged by a magnet to prevent unauthorized removal, and a cam lock mechanism to control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire electronic lock is replaced to ensure security, then security is improved, but cost and logistics are worsened
Solution Approach 1:
The electronic lock is divided into separable components: a reusable lock housing and a replaceable electronic lock core. The core contains the electronic components (microprocessor, encryption circuitry) that require replacement for security updates, while the housing and mechanical components can be retained, avoiding full lock replacement and reducing cost.
Solution Approach 2:
The electronic lock core is extracted as a distinct, removable module from the lock housing. This extracted core can be replaced independently to address security concerns without replacing the entire lock assembly, thereby reducing material consumption and cost while maintaining security.
2Ease of operation
If the electronic lock core is made easily replaceable, then ease of operation is improved, but security is worsened
Solution Approach 1:
The retainment assembly transitions between locked and unlocked states dynamically. The control lug engages with the control slot to secure the core during normal operation, but can be disengaged by rotating the control knob, enabling controlled replacement. This dynamic mechanism ensures security during use while allowing authorized replacement.
Solution Approach 2:
The control knob acts as an intermediary mechanism between the user and the retainment assembly. Rotating the knob actuates the control lug to disengage from the control slot, providing a controlled interface for core replacement that maintains security while enabling ease of operation for authorized users.
3Ease of operation
If the screw guard is made accessible for easy maintenance, then ease of operation is improved, but unauthorized removal is worsened
Solution Approach 1:
The screw guard transitions between a protected state (magnetically attached to the screw head) and an accessible state (removed). The magnetic attachment provides anti-theft protection during normal operation, while the controlled removal process allows authorized maintenance access when needed.
Solution Approach 2:
The magnet serves as an intermediary that creates a controlled access mechanism. The magnetic force secures the screw guard to prevent unauthorized removal, while authorized users can overcome this magnetic attachment to access the screw for maintenance, balancing security with serviceability.

AI summary
Electronic locks can provide improved security over mechanical locks. Despite the improved security of electronic locks, there may be occasions where it is desirable to replace the electronic lock. Replacing an electronic lock can be expensive and challenging, particularly if the electronic lock is being replaced by a different electronic lock produced by a different manufacturer. The present disclosure relates to an electronic lock with a replaceable lock core that enables replacing the electronic lock core with a new electronic lock core without needing to replace the entire electronic lock. Further, through use of access controls managed by the electronic lock and electronic key combination, and the unique mechanical configurations disclosed herein, it is possible to replace an electronic lock core without compromising security of a device or location secured by the electronic lock.
