Electronic Lock Linking Module for Dual-Rotation Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic locks require two identical control mechanisms, leading to complex structures prone to failure and safety concerns, especially in emergency situations like power outages where users inside the vault may be trapped.
Innovation Solution
A linking module that uses a single driving member to simultaneously control a pair of identical structures through a linking member, allowing simultaneous rotation of two rotating members and clutch modules, simplifying the control structure and ensuring one-way access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two identical control mechanisms are used for internal and external control, then the electronic lock can provide both internal and external access control functions, but the structure becomes complex and prone to failure
Solution Approach 1:
The patent merges two identical control mechanisms into a single integrated control structure. The first and second rotating members are connected through a linking mechanism that shares common components (linking member, driving member, driven portion), allowing both internal and external control functions to be achieved through one unified structure rather than two separate mechanisms.
Solution Approach 2:
The single control structure is designed to perform multiple functions - it can control both the first rotating member (for internal access) and the second rotating member (for external access) through the same driving member and linking mechanism, making the system universal and multi-functional while reducing overall complexity.
2Ease of operation
If automatic unlocking mechanism upon power outage is adopted, then users inside the vault can unlock the door during emergency, but users outside the vault can freely enter the vault after power outage, resulting in loss of anti-theft function
Solution Approach 1:
The patent inverts the traditional automatic unlocking approach. Instead of automatically unlocking upon power outage, the system is designed so that the internal control mechanism (first rotating member) can be operated during emergency, while the external control mechanism (second rotating member) requires power. The linking mechanism ensures that when power is out, only the internal side can function, maintaining security while providing emergency escape.
Solution Approach 2:
The system dynamically adjusts its control characteristics based on power availability. When power is normal, both internal and external control mechanisms function as designed. When power fails, the system automatically transitions to a state where only internal control is available, providing dynamic adaptability to emergency conditions while maintaining security protocols.

AI summary
A linking module (60) for an electronic lock (100) has a first rotating member (61) and a second rotating member (62). Both the first rotating member (61) and the second rotating member (62) are connected to a linking member (64). The linking member (64) is connected to a driving member (67). The linking member (64) is driven by the driving member (67), enabling the linking member (64) to drive the first rotating member (61) and the second rotating member (62) to rotate simultaneously, thereby simplifying the control structure of the electronic lock greatly.
