Solution Overview

Problem

Existing lock systems lack communication options between the lock and counter-lock, limiting coordinated unlocking and locking operations.

Innovation Solution

Incorporating communication means within the lock and counter-lock electronic devices, allowing for unidirectional or bidirectional data exchange via wireless or wired connections, enabling coordinated state changes and communication with other electrical devices like motorized door drives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If communication means are integrated into lock and counter-lock electronic devices, then coordinated locking and unlocking operations are enabled, but device complexity increases

Engineering Contradiction:
Improvecoordinated locking operationVSAvoidcommunication means integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates communication means directly into the existing lock electronic device and counter-lock electronic device, merging the communication function with the locking control function. This allows the lock and counter-lock to exchange data and coordinates their locking/unlocking operations without requiring separate communication hardware, thus improving reliability while managing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electronic devices in the lock and counter-lock are designed to perform multiple functions: traditional locking control and data exchange. By making the electronic devices universal, the patent enables coordinated operations without adding dedicated separate communication devices, addressing the contradiction between reliability improvement and complexity increase.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If bidirectional communication is implemented between lock and counter-lock, then synchronized door operations are achieved, but manufacturing cost increases

Engineering Contradiction:
Improvesynchronized door operationsVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent combines bidirectional communication capability into the existing electronic devices of the lock and counter-lock systems. By integrating the communication function rather than adding separate communication modules, the patent achieves synchronized door operations while minimizing the increase in manufacturing cost.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lock and counter-lock electronic devices serve themselves by performing both locking control and communication functions. This self-service approach allows bidirectional communication to be implemented using the existing electronic infrastructure, reducing the need for additional components and thereby controlling manufacturing costs while achieving synchronized operations.

Inventive Principle:
Principle #25Self-service
