Solution Overview

Problem

Current passive optical networks face challenges in efficiently extending fiber optic services to new areas due to limitations in modular and protective enclosures for optical fiber connections, splices, and splitters, which affect network reliability and complexity.

Innovation Solution

A telecommunications enclosure with modular elements, such as splitter modules and storage trays, that allow for secure, flexible, and expandable fiber optic connections, including pivotable covers, anchoring systems, and cable management features to accommodate fiber growth and separate feeder and branch cables, enhancing network reliability and ease of maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional non-modular enclosures are used for fiber optic connections, then structural simplicity is maintained, but adaptability and ease of maintenance deteriorate

Engineering Contradiction:
ImproveadaptabilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The enclosure is divided into modular components including removable trays, separable compartments for different fiber types, and independent access points. This segmentation allows the system to adapt to different configuration needs while maintaining overall structural integrity, resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular trays and compartments are designed to perform multiple functions - accommodating different fiber types (feeder, branch, distribution), providing splice protection, enabling cable management, and facilitating maintenance access. This multi-functionality increases adaptability without proportionally increasing complexity.

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

2Productivity

If fiber optic services are extended to new areas, then network coverage is improved, but network complexity and management difficulty increase

Engineering Contradiction:
Improvenetwork extension efficiencyVSAvoidnetwork complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The enclosure provides segregated compartments for different fiber categories (feeder fibers in one section, branch fibers in another, distribution fibers in a third). This segmentation simplifies network extension by allowing independent management of each fiber type, enabling productivity improvement without proportional complexity increase.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular trays act as intermediaries between the fixed enclosure structure and the variable fiber connections. These trays can be easily installed, removed, and reconfigured, serving as a flexible interface that simplifies network extension while containing complexity within standardized components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of repair

If modular components are added to the enclosure, then ease of maintenance and adaptability improve, but device complexity increases

Engineering Contradiction:
Improveease of maintenanceVSAvoidcomplexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The enclosure features removable trays and separable compartments that can be independently accessed and maintained. This segmentation allows maintenance personnel to service specific components without disassembling the entire system, improving ease of repair while the modular design keeps complexity manageable through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Problematic or failed components such as splice trays, connectors, or cable management elements can be individually extracted from the enclosure for repair or replacement. This extraction capability significantly improves maintenance ease while the standardized extraction interfaces prevent complexity from escalating.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If cable management features are added to separate feeder and branch cables, then connection reliability improves, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcomplexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The enclosure provides dedicated segregated compartments and routing channels for feeder cables and branch cables. This physical segmentation prevents cable confusion and connection errors, improving reliability while the standardized compartment design keeps the added complexity predictable and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the enclosure are designed with specific local qualities - feeder cable sections have particular routing characteristics, branch cable sections have different organization patterns, and distribution areas have specialized access points. This local optimization improves connection reliability without requiring complete system redesign, limiting complexity increases.

Inventive Principle:
Principle #3Local quality
