Solution Overview

Problem

Current fiber access terminals struggle to support multiple optical cable connection methods, such as field-mountable optical connectors, fast connectors, and splicing, requiring operators to purchase different terminals based on connection scenarios.

Innovation Solution

An optical cable connection apparatus is designed with a top cover, bottom housing, flap, optical fiber connection module, and splicing assemblies, allowing for the connection of optical cables through on-site fabrication of field-mountable connectors, use of fast connectors, and splicing, thereby supporting multiple connection methods within a single apparatus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fiber access terminal is used, then device complexity is reduced, but it cannot support multiple connection methods (FMC, fast connector, splicing)

Engineering Contradiction:
Improveconnection method compatibilityVSAvoidterminal structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fiber access terminal is designed with multiple functional modules including an optical cable connection module for FMC and fast connector connections, and a splicing module for splicing operations. This multi-functional design allows a single terminal to support all three connection methods (FMC, fast connector, and splicing), eliminating the need for separate terminals for each connection type while maintaining comprehensive connection capabilities

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

Solution Approach 2:

The terminal is divided into distinct functional modules: an optical cable connection module containing optical cable holes and connection interfaces, and a splicing module containing splicing slots and spool structures. This segmentation allows each module to handle specific connection methods independently, making the overall system versatile while keeping each component relatively simple and manageable

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If different fiber access terminals are purchased for different connection scenarios, then connection compatibility is achieved, but operational complexity and cost increase

Engineering Contradiction:
Improveconnection scenario supportVSAvoidterminal selection and management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The terminal integrates multiple connection capabilities into a single device, allowing operators to use one terminal for all connection scenarios rather than selecting and managing multiple specialized terminals. The optical cable connection module handles FMC and fast connector connections, while the splicing module handles splicing operations, simplifying operational complexity

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

3Adaptability or versatility

If splicing modules are added to support splicing connection, then connection versatility improves, but device complexity increases

Engineering Contradiction:
Improvesplicing connection supportVSAvoidmodule structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The splicing function is segmented into distinct components: splicing slots for positioning and securing spliced cables, and spool structures for managing loose cable sections. This segmentation allows the splicing module to be designed as a relatively simple, self-contained unit that can be integrated into the terminal without significantly increasing overall complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The splicing module is merged with the optical cable connection module within the same terminal housing, sharing common structural elements such as the bottom housing and top cover. This merging approach allows the terminal to support splicing connections while minimizing the increase in device complexity by reusing existing structural components

Inventive Principle:
Principle #5Merging (Combining)
