Interchangeable Electromechanical Lock Core with Blocking Cam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mechanical interchangeable lock cores require costly and inconvenient replacement when a key is compromised, posing a security risk and necessitating the rekeying or replacement of all locks, whereas contactless RFID technologies offer easier maintenance but are not easily adopted due to the entrenched installed base of mechanical locks.
Innovation Solution
An electromechanical lock core that can be inserted into existing mechanical lock housings, controlled by a contactless reader and credential, allowing secure access and maintenance without full lock replacement, featuring a blocking cam and actuator mechanism for secure insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical interchangeable lock cores are used, then the installed base is entrenched and familiar, but replacement is costly and inconvenient when keys are compromised
Solution Approach 1:
The patent replaces the traditional mechanical key-based control system with an electromechanical system that uses contactless RFID credentials. The lock core includes a contactless reader that communicates with RFID credentials, and an actuator that converts electromagnetic signals into mechanical motion to control the blocking cam. This substitution eliminates the need for mechanical key manipulation while maintaining the interchangeable core functionality, thereby improving security without compromising maintenance convenience.
Solution Approach 2:
The electromechanical lock core is designed to be universally compatible with existing mechanical lock housings while incorporating multiple functions: contactless RFID credential verification, electromechanical actuation of the blocking cam, and maintenance mode activation. This multi-functionality allows a single device to replace both traditional mechanical locks and electronic access control systems, making it easier to adopt without full infrastructure replacement.
2Reliability
If electromechanical locks with contactless control are adopted, then security is improved and maintenance is easier, but the entire lock must be replaced to upgrade from mechanical
Solution Approach 1:
The patent segments the lock system into two independent parts: the lock housing (which remains mechanical and existing) and the interchangeable electromechanical core (which contains the contactless reader, actuator, and blocking cam). This segmentation allows customers to upgrade only the core component while retaining the existing housing, significantly reducing replacement complexity and cost compared to replacing the entire lock assembly.
Solution Approach 2:
The electromechanical core is designed to nest within the existing mechanical lock housing. The core contains the contactless reader, actuator mechanism, and blocking cam in a compact arrangement that fits within the standard housing dimensions. This nesting approach allows the advanced electromechanical functionality to be integrated into traditional lock configurations without requiring new housing or extensive installation modifications.
3Ease of operation
If mechanical locks are replaced with electromechanical locks, then contactless control and easier maintenance are achieved, but the cost and complexity of full lock replacement increases
Solution Approach 1:
By segmenting the lock system into a reusable housing and an upgradeable core, the patent reduces installation costs. Existing mechanical housings can be retained and reused, and only the core needs to be installed or replaced. This segmentation allows for modular installation where the core can be independently handled, reducing labor costs and material waste associated with replacing entire lock assemblies.

AI summary
The invention concerns an electromechanical lock. More specifically, the invention concerns an interchangeable electromechanical lock core that is equipped with a blocking cam that secures the lock core in a mating housing. The blocking cam may be coupled to a plug and the plug may be coupled to a knob. Once both couplings have occurred, the knob can be turned to actuate the blocking cam.
