Fibre Tray Pivot Mechanism for Enclosure Space Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fibre-optic distribution enclosures often face challenges in flexibility during installation in spaces with limited room for moving fibre trays out of their storage positions, leading to difficulties in accessing and splicing optical fibres due to rigid orientations and space constraints.
Innovation Solution
A fibre-optic distribution enclosure design featuring dual fibre tray support means that allow the fibre tray to be moved into two distinct storage positions, with the first and second spaces intersecting, enabling flexibility in orientation and space usage without requiring reorientation of the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fibre tray is designed to move between storage and access positions in a distribution closet with limited space, then the enclosure can protect fibres effectively, but the installer cannot access the fibre tray for splicing due to space constraints
Solution Approach 1:
The fibre tray is designed to be movable between a storage position (where it is concealed within the enclosure for protection) and an access position (where it can be pulled out for splicing operations). This dynamic positioning allows the same component to serve both protective and accessible functions depending on operational needs.
Solution Approach 2:
The invention introduces a new spatial dimension by allowing the fibre tray to move not only along the horizontal axis but also by rotating about a pivot point. This rotational movement enables the tray to be positioned in different orientations, providing access from multiple directions and solving the space constraint problem in distribution closets.
2Ease of manufacture
If the enclosure is designed with a fixed orientation for the feeder cable entrance port, then the cable routing is simplified, but the enclosure cannot be installed in different orientations to accommodate limited space
Solution Approach 1:
The fibre tray is designed to be movable between a storage position (where it is concealed within the enclosure for protection) and an access position (where it can be pulled out for splicing operations). This dynamic positioning allows the same component to serve both protective and accessible functions depending on operational needs.
Solution Approach 2:
The invention introduces a new spatial dimension by allowing the fibre tray to move not only along the horizontal axis but also by rotating about a pivot point. This rotational movement enables the tray to be positioned in different orientations, providing access from multiple directions and solving the space constraint problem in distribution closets.
3Volume of stationary object
If the fibre tray occupies a fixed space in the enclosure, then the enclosure size is minimized, but the tray cannot be moved to an accessible position for splicing
Solution Approach 1:
The fibre tray is designed to be movable between a storage position (where it is concealed within the enclosure for protection) and an access position (where it can be pulled out for splicing operations). This dynamic positioning allows the same component to serve both protective and accessible functions depending on operational needs.
Solution Approach 2:
The invention introduces a new spatial dimension by allowing the fibre tray to move not only along the horizontal axis but also by rotating about a pivot point. This rotational movement enables the tray to be positioned in different orientations, providing access from multiple directions and solving the space constraint problem in distribution closets.

AI summary
Fibre-optic distribution enclosure, comprising a fibre tray (200), a storage volume (500) for storing the fibre tray (200) in the fibre-optic distribution enclosure when the fibre tray (200) is in a first tray storage position, and a enclosure base. The enclosure base comprises first and second fibre tray support means (270, 271) for movably fixing the fibre tray (200) to the enclosure base such that the fibre tray (200) can be moved into a first or into a second tray storage position in the storage volume, respectively. The fibre tray (200) occupies a first space (S1) in the first storage position, and a second space (S2) in the second storage position, and the first space (S1) and the second space (S2) intersect, i.e. they have space in common.
