Solution Overview

Problem

Existing fiber optic cable splicing modules lack flexibility and adaptability in routing fiber optic cables, making it difficult to install and maintain fiber optic connections, especially when transitioning between continuous and separated cables, and do not easily accommodate customer-specific preferences for security and ease of reconfiguration.

Innovation Solution

A splice module design with a patch unit that includes both patch points with detachable connections and passage points without connections, allowing for continuous routing of fiber optic cables, where patch points and passage points are strategically arranged to minimize spatial changes and maintain direct relationships, enabling easy installation and future modifications by allowing cables to be routed through or separated at adjacent points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If only patch points with detachable connections are provided, then ease of connection and disconnection is improved, but flexibility in routing continuous cables and adaptability to different customer requirements deteriorates

Engineering Contradiction:
Improveease of connection and disconnectionVSAvoidflexibility in routing continuous cables
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patch unit is segmented into two distinct types of connection points: patch points with detachable connection elements for pluggable connections, and passage points without detachable connection elements for continuous cable routing. This segmentation allows the system to simultaneously support both easy detachment/reconnection and continuous cable routing flexibility without compromising either function.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If patch points are densely arranged to maximize connectivity, then ease of operation is improved, but device complexity increases due to routing constraints

Engineering Contradiction:
Improveease of installation and maintenanceVSAvoidspatial arrangement complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Different local qualities are assigned to different connection points within the patch unit. Patch points are designed with detachable connection elements for easy pluggable connections, while passage points are designed without detachable elements to facilitate continuous cable routing. This local differentiation simplifies the overall spatial arrangement by providing clear functional distinction, reducing routing complexity despite high density.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If traditional splice module designs are used, then manufacturing simplicity is maintained, but adaptability to customer-specific preferences and future modifications deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidadaptability to customer requirements
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patch unit is designed with multi-functionality, incorporating both patch points for detachable connections and passage points for continuous routing within a single integrated structure. This universal design allows the same hardware to accommodate various customer requirements such as security preferences, provider switching needs, and future modifications without requiring custom manufacturing for each scenario.

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

AI summary

The invention relates to a splice module for fiber optic cables with splice trays and a patch unit which, in addition to patch points with a detachable connection device for one of the cables, also has through points without such a detachable connection device and instead an opening, wherein the patch points and the through points are closest to each other.
