Switchable Lock Modes for Privacy and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing room door locks with a single back-locking structure cannot meet the varying privacy requirements of users across different usage scenarios.
Innovation Solution
A lock with multiple switchable operating modes, featuring a front lock body, rear lock body, connecting rod, electric clutch mechanism, mechanical lock cylinder, identification module, and a first linkage mechanism that allows the lock to be switched between two operating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single back-locking structure is used, then the lock structure is simple, but it cannot meet varying privacy requirements in different usage scenarios
Solution Approach 1:
The lock implements dynamic functionality by enabling the moving member to switch between first and second operating positions, allowing the lock to adapt between different operating modes (first operating mode with electric unlocking and second operating mode without electric unlocking) to meet varying privacy requirements
Solution Approach 2:
The lock achieves multi-functionality by integrating both electric clutch mechanism and mechanical lock cylinder, enabling it to perform multiple functions: electric unlocking in first operating mode and key-based mechanical unlocking in second operating mode, thus accommodating different usage scenarios
2Adaptability or versatility
If multiple operating modes are added, then the lock functionality is expanded, but the device complexity increases
Solution Approach 1:
The patent merges the electric clutch mechanism and mechanical lock cylinder into a single integrated locking system, where both mechanisms share common components such as the driving member and connecting rod, reducing overall complexity while maintaining multiple operating modes
Solution Approach 2:
The locking function is segmented into two independent but complementary mechanisms: electric clutch mechanism for electric unlocking and mechanical lock cylinder for key-based unlocking, allowing each mechanism to operate independently while contributing to the overall multi-mode functionality

AI summary
A lock with multiple switchable operating modes has a first operating mode and a second operating mode. In the first operating mode, a moving member can trigger a first switch member, so that a control module can control the electric clutch mechanism to work only when receiving specific identification information, thereby limiting a condition that the lock can be opened. In the second operating mode, the moving member can drive a blocking member to move so as to prevent a first clutch member and a driving member from being engaged, in this case, any identification information input cannot achieve electric unlocking, and a mechanical lock cylinder can only be unlocked using a key.
