Solution Overview

Problem

Current methods for managing and maintaining telecommunications networks and systems, particularly in relation to fiber optic cables, are inadequate for efficient repair, maintenance, and upgrades, and lack effective cable routing solutions.

Innovation Solution

The adapter cassette with a wedge-shaped housing and angled fiber optic adapters, combined with a quick-release cover, provides efficient access and minimizes space usage, allowing for easy integration into enclosures and panels, and facilitates better cable routing by angling exterior connections for improved routing flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If fiber optic adapters are mounted at an angle relative to the front plane, then cable routing flow is improved and space usage is minimized, but device complexity increases

Engineering Contradiction:
Improvecable routing flowVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The fiber optic adapters are mounted at an angle (e.g., 45 degrees) relative to the front plane of the housing, creating an asymmetric configuration that optimizes cable routing flow and minimizes space usage while maintaining functional effectiveness

Inventive Principle:
Principle #4Asymmetry

2Ease of repair

If a quick-release cover is implemented, then access to internal components is improved and maintenance time is reduced, but device complexity increases

Engineering Contradiction:
Improveaccess to internal componentsVSAvoiddevice complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The housing is segmented into a main body and a removable quick-release cover, allowing the cover to be easily detached for access to internal components and then quickly reattached to restore protection, thereby simplifying maintenance operations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover transitions from a static enclosed structure to a dynamic removable component with quick-release latches, enabling rapid state changes between closed (protected) and open (accessible) configurations for efficient maintenance

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If the adapter cassette is designed to minimize space usage, then area efficiency is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvearea efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The angled fiber optic adapters are nested within the housing structure in a space-efficient arrangement, with components positioned to utilize available volume optimally, reducing the overall footprint of the adapter cassette

Inventive Principle:
Principle #7Nested doll (Nesting)
