Solution Overview

Problem

Fiber optic modules face challenges with disorganization and tangling of cables, inadequate slack storage, and difficult access due to back-entry configurations, which complicate maintenance and require multiple splice modules for different splicing scenarios.

Innovation Solution

A multi-layer splice module with a hinged transparent cover, separate layers for cable, splice, and pigtail storage, front-entry openings, and adaptable adapter plates to accommodate various adapter types, allowing for organized routing and storage of multi-fiber cables and facilitating easy maintenance within confined spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a multi-fiber cable is routed to a splice module with back entry opening, then the module can store excess slack and facilitate splicing, but the cable may become disorganized and tangled within the module

Engineering Contradiction:
Improvesplicing connection reliabilityVSAvoidcable organization and maintenance accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The module is divided into multiple functional layers: a first layer for receiving and organizing the multi-fiber cable with separate channels for each fiber, a second layer for splicing operations, and a third layer for storing excess cable slack. This segmentation prevents cable tangling by providing dedicated pathways for each fiber while maintaining splicing functionality.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If a splice module is configured with back entry opening for cable access, then splicing can be performed, but maintenance becomes difficult due to confined access

Engineering Contradiction:
Improvemodule installationVSAvoidmaintenance accessibility
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The module provides dual access methods: traditional back entry for initial installation and a hinged cover on the front face for maintenance. This inversion of the typical access pattern allows technicians to perform maintenance from the front of the rack without requiring back access, significantly improving ease of repair while maintaining installation capabilities.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If multiple splice modules are carried to a site to accommodate different splicing scenarios, then both single fiber and mass fusion splicing can be supported, but the device complexity and number of components increases

Engineering Contradiction:
Improvesplicing type flexibilityVSAvoidnumber of splice modules required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The module is designed with universal adaptability to perform multiple splicing functions: single fiber splicing, mass fusion splicing, and cable storage. The configurable adapter plate and multi-layer structure allow the same module to adapt to different splicing scenarios, eliminating the need to carry multiple specialized modules while maintaining full functionality.

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

4Ease of operation

If adapters are mounted with front opening configuration in telecommunications rack, then cable access is improved, but the splice module becomes difficult to install and maintain

Engineering Contradiction:
Improvecable accessVSAvoidinstallation and maintenance difficulty
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The module utilizes the vertical dimension within the rack space by implementing a multi-layer stacked structure. Cables enter from the front and are routed vertically through dedicated channels to each layer, allowing front access while organizing cables in the vertical dimension to prevent tangling and simplify installation and maintenance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
