Electromechanical Lock Core Coupling for Low-Part Secure Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromechanical locking systems are complex, cumbersome to manufacture and assemble, and require multiple parts, making them inefficient and difficult to use with different lock sets.
Innovation Solution
An electromechanical lock assembly with a lock core that is rotatably mounted within a lock body, featuring an annular element that is rotationally and axially displaced by a coupling device upon insertion of an appropriate key, and a blocking arrangement that prevents unauthorized rotation using a stationary blocking member and contact surfaces to ensure secure and efficient operation.

Engineering Contradiction Analysis
1Reliability
If a complex electromechanical locking system with multiple parts is used, then the locking function can be achieved, but the device complexity increases and manufacturing becomes cumbersome
Solution Approach 1:
The patent combines the lock core, annular element, coupling device, and blocking arrangement into a single integrated locking system. The lock core and annular element are mounted together on a common mounting surface, and the coupling device integrates multiple functions (rotational locking, axial positioning) into one mechanism. This merging reduces the total number of separate parts while maintaining reliable locking functionality.
Solution Approach 2:
The annular element serves multiple functions: it acts as a rotational lock when engaged with the coupling device, provides axial positioning through contact surfaces, and enables the blocking arrangement to prevent unauthorized rotation. The coupling device itself performs both rotational coupling and axial movement control. This multi-functionality reduces the need for separate components.
2Reliability
If traditional electromechanical locking systems are used, then locking can be achieved, but ease of manufacture and assembly deteriorates due to multiple parts
Solution Approach 1:
By integrating the lock core, annular element, and coupling device into a compact assembly mounted on a common surface, the patent simplifies manufacturing and assembly processes. Fewer separate parts mean fewer assembly steps and reduced manufacturing complexity while maintaining secure locking capability.
3Reliability
If multiple electrical actuators are used for locking and unlocking, then the locking function is achieved, but power consumption increases
Solution Approach 1:
The locking and unlocking mechanism uses manual key insertion and rotation to drive the lock core and annular element. The coupling device engages and disengages through the mechanical rotation of the key, eliminating the need for electrical actuators. This self-service mechanical operation significantly reduces power consumption while maintaining reliable locking and unlocking functions.
