Synchronized Door Lock Mechanism for Emergency Escape

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing escape door lock mechanisms require separate unlocking of top and bottom locks, which wastes time and hinders emergency escape due to the sequential operation of these locks.

Innovation Solution

A door lock device featuring a synchronized unlocking mechanism that interconnects the top and bottom locks through an acting assembly and operation assembly, allowing both locks to be unlocked simultaneously via a coordinated mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate unlocking of top and bottom locks is used, then each lock can be secured independently, but the unlocking time is increased and emergency escape is hindered

Engineering Contradiction:

Improvelock securityVSAvoidunlocking time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the unlocking functions of the top lock and bottom lock into a single integrated mechanism. The operating assembly, through the acting member and driving member, simultaneously actuates both lock structures, allowing them to be unlocked together by a single operation rather than requiring separate unlocking actions for each lock.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The acting assembly is pre-configured with acting portions that are positioned to engage both the first lock structure and second lock structure in advance. When the driving member rotates, the acting portions are already in place to immediately push both locks to their unlocked positions, eliminating the need for sequential operation.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If separate unlocking of top and bottom locks is used, then each lock can be controlled independently, but the operational complexity increases during emergency situations

Engineering Contradiction:

Improvelock control flexibilityVSAvoidemergency operation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the control of top and bottom locks into a single operating assembly. The actuating mechanism with the driving member simultaneously controls both lock structures, reducing the number of operations required during emergencies while maintaining the ability to secure both locks independently when needed.

Inventive Principle:

Principle #5Merging (Combining)

3Loss of time

If synchronized unlocking mechanism is implemented, then unlocking time is reduced, but the device complexity increases

Engineering Contradiction:

Improveunlocking timeVSAvoidmechanism complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces an acting assembly as an intermediary mechanism between the driving member and the lock structures. The acting member with its acting portions serves as a mediator that translates the rotation of the driving member into simultaneous linear motion that pushes both locks to their unlocked positions, achieving synchronization without requiring complex direct linkage between the two locks.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A door lock device is provided and includes: a lock assembly having a first lock structure and a second lock structure; an acting assembly interlocked with the first lock structure and the second lock structure; and an operation assembly interlocked with the acting assembly so as to unlock the first lock structure and the second lock structure synchronously. Therefore, when the lock assembly is in the form of top and bottom locks, the top and bottom locks can be unlocked at the same time, so as to allow an escape door to be opened quickly, thereby facilitating emergency escape.
