Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications enclosures face challenges in maximizing fiber management within a given volume while ensuring versatility for different types of optical connections and maintaining water and contaminant resistance, particularly in re-enterable closures.
Innovation Solution
A fiber management organizer for telecommunications closures featuring a main body with distinct cable management regions, a rotatable tray assembly, and a demarcation cover that provides selective access, utilizing snap-fit connections and locking mechanisms for enhanced flexibility and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the closure is designed to be re-enterable with separate access panels, then ease of operation is improved, but water and contaminant resistance may be compromised
Solution Approach 1:
The closure is divided into separate access panels that can be opened independently while maintaining the overall sealed structure. Each panel can be accessed without opening the entire closure, allowing maintenance operations while preserving the protective enclosure.
Solution Approach 2:
Gel seals are used as intermediary sealing elements between the access panels and the main closure body. These gel seals provide water and contaminant resistance while allowing the panels to be opened and closed for access.
2Productivity
If the organizer is sized to maximize fiber management capacity within a given volume, then productivity is improved, but device complexity increases
Solution Approach 1:
The organizer employs nested trays and compartments that can be stacked and configured in multiple levels within the closure volume. This nested arrangement maximizes the use of available space for fiber management while maintaining a relatively simple overall structure.
Solution Approach 2:
The organizer utilizes vertical stacking and multi-level tray arrangements to expand fiber management capacity in the vertical dimension rather than only horizontally. This approach increases capacity without proportionally increasing the footprint or overall complexity.
3Object-affected harmful factors
If the closure includes comprehensive sealing blocks at all port locations, then water and contaminant resistance is improved, but device complexity increases
Solution Approach 1:
Gel seals are applied specifically at port locations and access panel interfaces where water and contaminant ingress is most likely to occur. This localized sealing approach provides effective protection without requiring comprehensive sealing throughout the entire closure structure.

AI summary
A fiber management organizer for a telecommunications closure includes a main body defining a first cable management region, a tray assembly extending over at least a portion of the first cable management region, the tray assembly including a tower mounted to oppositely positioned side walls of the main body, a plurality of trays rotatably mounted to the tower such that the trays are rotatable about an axis orthogonal to the longitudinal axis; and a cover support part disposed between the main body and the tower, the cover support part covering at least a portion of the first cable management region and supporting a central portion of the tower above the first cable management region. A demarcation cover can also be provided with the tray assembly to secure the trays in a closed position and limit access to the trays. The cover can be locked closed and unlocked. When unlocked, the cover can be pivoted to one or more stable open positions to provide access to the sensitive area without having to completely remove the cover from the organizer.
