Outdoor Telecom Cabinet with Segmented Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor telecommunications cabinets lack robustness, compactness, and water-tightness, and are not well-suited for managing optical fibre cabling and connections when accessed by multiple telecommunication operators, particularly in mutualization applications, leading to complexity and maintenance challenges.
Innovation Solution
A single-piece outdoor telecommunications cabinet with two compartmentalized areas, one for user network connections and another for external fibre-optic telecommunication networks, utilizing optical fibre patch cords and a connector holder for temporary storage and protection of connectors, allowing secure access and simplified management by different operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple telecommunication operators access the cabinet to connect their external fibre-optic networks, then the cabinet provides mutualization functionality, but the management of optical fibre cabling and connections becomes complex and maintenance becomes difficult
Solution Approach 1:
The cabinet interior is divided into multiple operator-specific compartments, each housing dedicated optical fibre cabling and connection elements for a specific telecommunication operator. This segmentation allows each operator to manage their own cabling independently within their designated compartment, preventing the complexity that would arise from mixed cabling while maintaining mutualization functionality across multiple operators.
2Ease of operation
If optical fibre connectors are left exposed for easy connection, then the ease of operation is improved, but the connectors are vulnerable to damage and contamination
Solution Approach 1:
Optical fibre connectors are nested within protective housings that are integrated into the cabinet structure. The connectors can be accessed and connected through designated openings in the housings, allowing easy operation while the housings provide protection against damage and contamination. The nested structure maintains connector accessibility while ensuring their protection.
3Reliability
If the cabinet structure is made robust and water-tight for outdoor use, then the reliability is improved, but the ease of manufacture decreases
Solution Approach 1:
The cabinet is constructed as an assembly of separate components including the case, closure doors, and internal compartments that can be manufactured independently using standard fabrication processes. The robust and water-tight properties are achieved through designed joints and sealing elements between these segments, allowing each component to be manufactured separately with easier processes while the assembled structure provides the required outdoor durability.
