Solution Overview

Problem

Conventional electronic locks require two identical control mechanisms for internal and external operation, leading to complex structures prone to failure and safety concerns during power outages, particularly in secure environments like bank vaults.

Innovation Solution

A linking module that uses a single driving member to simultaneously control a pair of identical structures through a linking mechanism, comprising rotating members, linking members, and a driving member, allowing synchronized operation of internal and external handles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two identical control mechanisms are used for internal and external operation, then the electronic lock can be controlled from both sides, but the structure becomes complex and prone to failure

Engineering Contradiction:

Improvecontrol capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

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 member that shares a common pivoting portion, allowing both internal and external handles to operate a unified locking mechanism rather than two separate ones, thereby reducing structural complexity while maintaining bidirectional control capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The common pivoting portion serves multiple functions: it acts as the rotation axis for both the first and second rotating members, and simultaneously functions as the pivoting axis for the linking member. This multi-functional design eliminates the need for separate pivot points for each handle, simplifying the overall structure while enabling control from both sides of the door

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If automatic unlocking mechanism upon power outage is adopted, then users inside can escape during emergencies, but users outside can freely enter the vault, resulting in loss of anti-theft function

Engineering Contradiction:

Improveemergency safetyVSAvoidsecurity vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the traditional automatic unlocking approach by implementing automatic locking instead. Upon power outage detection, the electronic locking mechanism automatically engages, ensuring that users inside remain secured while preventing unauthorized entry from outside. This inverted approach maintains security during emergencies rather than compromising it for escape access

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A linking module for an electronic lock has a first rotating member and a second rotating member. Both the first rotating member and the second rotating member are connected to a linking member. The linking member is connected to a driving member. The linking member is driven by the driving member, enabling the linking member to drive the first rotating member and the second rotating member to rotate simultaneously, thereby simplifying the control structure of the electronic lock greatly.
