Lock Coupling Slide for Independent Switching Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks lack flexibility and security in access control, as the switching function often requires operating a latch, which can complicate operation and reduce security when trying to independently manage locking and switching functions.
Innovation Solution
A lock design featuring a rotatable lock nut with two nut parts and a coupling slide, where the coupling slide is actuated by the locking cylinder to engage or disengage the nut parts, allowing for independent control of the switching function without affecting the latch, enhancing flexibility and security by allowing the bolt to be locked in multiple positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the switching function is implemented by operating the latch, then the locking and switching functions are integrated, but the operation becomes more complex and security is reduced
Solution Approach 1:
The lock mechanism is divided into independent functional modules: the latch for basic locking and the coupling slide for switching function. This segmentation allows each component to perform its specific function without interfering with the other, resolving the contradiction between integrating switching functionality and maintaining operational simplicity.
Solution Approach 2:
The coupling slide acts as an intermediary element between the lock cylinder and the latch mechanism. It receives actuation from the lock cylinder and translates it into appropriate latch positioning, enabling the switching function to be activated without directly operating the latch, thus maintaining operational simplicity.
2Adaptability or versatility
If the latch is operated for switching, then the switching function can be activated, but the locking security is compromised when the bolt is extended
Solution Approach 1:
By separating the switching function into a distinct coupling slide mechanism independent from the latch, the system can activate switching without compromising the latch's security function. The coupling slide operates separately and does not interfere with the latch's ability to secure the bolt in extended positions.
Solution Approach 2:
The coupling slide is designed to be actuated by the lock cylinder in a controlled sequence, preparing the switching function activation before it affects the latch. This preliminary action ensures that the locking security is maintained until the switching function is properly initiated through the coupling slide mechanism.
3Reliability
If multiple pre-locked positions are provided, then security is enhanced, but the device complexity increases
Solution Approach 1:
The coupling slide mechanism serves multiple functions: it controls the switching function, manages the pre-locked positions, and coordinates with the latch mechanism. This multi-functionality allows the system to provide multiple pre-locked positions for enhanced security without proportionally increasing device complexity, as one component performs several critical roles.
