Solution Overview

Problem

Existing communication modules with separate overvoltage protection modules face challenges such as increased wiring effort and incorrect wiring, which can lead to communication failures due to electromagnetic interference and surges, especially in industrial settings where copper cables are being upgraded to fiber optics.

Innovation Solution

A communication module with a pluggable overvoltage protection module integrated into the communication circuit, featuring a gas arrester, protective diode, or thyristor, which reduces wiring effort and prevents incorrect connection through a secure single connection side, and includes a data interface for fault detection and reporting, allowing for remote monitoring and status querying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate surge protection modules are used for communication modules, then overvoltage protection is provided, but wiring effort increases and incorrect wiring may occur

Engineering Contradiction:
Improveovervoltage protectionVSAvoidwiring effort
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the communication module and surge protection module into a single integrated unit. The surge protection circuit is built into the communication module housing, eliminating the need for separate surge protection devices and reducing wiring complexity while maintaining protection functionality

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If separate surge protection modules are used, then overvoltage protection is achieved, but incorrect wiring and installation errors increase

Engineering Contradiction:
Improveovervoltage protectionVSAvoidinstallation correctness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By integrating the surge protection function directly into the communication module, the patent eliminates the separate installation step that could lead to wiring errors. The unified design ensures that protection is automatically configured correctly when the communication module is installed

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated design makes the surge protection self-configuring - it automatically works correctly when the communication module is installed without requiring separate wiring or configuration steps that could introduce errors

Inventive Principle:
Principle #25Self-service

3Ease of repair

If pluggable surge protection module is integrated, then replacement of defective components is enabled, but device structure becomes more complex

Engineering Contradiction:
Improvecomponent replacementVSAvoidmodule structure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The patent divides the communication module into separable functional units - the communication circuit and the surge protection module - where the surge protection module can be independently removed and replaced. This modular segmentation enables easy replacement of defective components while maintaining an organized internal structure

Inventive Principle:
Principle #1Segmentation
