Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-density fiber optic equipment requires advanced management and access solutions due to the increasing demand for fiber density in telecommunications, as traditional systems face challenges in efficiently organizing and accessing densely packed optical fibers.
Innovation Solution
A drawer-based telecommunications chassis with a slide assembly that includes tray rails and guides, featuring detents and flexible cantilever arms for latching, allowing trays to slide between stored and extended positions without increasing the overall width, enabling efficient access and organization of fiber optic equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional copper transmission equipment is used, then the system is easier to manage and access, but the transmission capacity and density are limited
Solution Approach 1:
The system is divided into multiple抽屉 (drawers) that can be independently accessed and managed. Each drawer contains organized fiber bundles and connection points, allowing technicians to work with specific fiber groups without disturbing the entire system. This segmentation maintains ease of operation while enabling high fiber density through systematic organization.
Solution Approach 2:
The patent transitions from two-dimensional surface mounting to three-dimensional spatial utilization by implementing vertical stacking of multiple drawers within a single chassis. This dimensional change allows significantly higher fiber density by exploiting the vertical space, while each drawer remains independently accessible through front-facing openings, preserving operational efficiency.
2Quantity of substance
If high-density fiber handling equipment is developed, then fiber density increases, but the complexity of organizing and managing fibers increases
Solution Approach 1:
The complex fiber management task is segmented into multiple drawers, each handling a specific subset of fibers. This division reduces the organizational complexity within each drawer while achieving high overall density through the cumulative capacity of multiple segmented units stacked vertically within the chassis.
Solution Approach 2:
Multiple drawers are nested vertically within a single chassis structure, with each drawer containing organized fiber bundles. This nested arrangement achieves high fiber density by efficiently utilizing vertical space, while the hierarchical organization (chassis → drawers → fiber bundles) simplifies management by creating clear levels of abstraction.
3Quantity of substance
If more drawers are added to increase capacity, then the transmission capacity increases, but the overall width of the chassis increases
Solution Approach 1:
Instead of adding drawers horizontally which would increase chassis width, the patent stacks drawers vertically within the same footprint. This dimensional transition from horizontal to vertical arrangement allows multiple drawers to be accommodated within the same width, thereby increasing equipment capacity without expanding the chassis width.
Solution Approach 2:
The equipment capacity is segmented into multiple independent drawers that can be stacked vertically. This segmentation allows the system to achieve high capacity through vertical stacking rather than horizontal expansion, maintaining a compact chassis width while accommodating multiple functional units.

AI summary
A slide assembly for slidably coupling a telecommunications tray to a telecommunications chassis includes a rail configured for mounting to the chassis, the rail defining a rail sliding cavity flanked by a first detent adjacent a first end and a second detent adjacent a second end of the rail, the rail further comprising first and second chassis mounting features, the first and the second chassis mounting features are oriented with respect to each other such that if two of the same rails are aligned and brought together in a juxtaposed relationship with the first and second chassis mounting features facing each other, the first and the second chassis mounting features can nest relative to each other so as to not increase the total width of the two rails. A guide configured for mounting to the telecommunications tray defines a guide sliding cavity configured to slidably receive the rail such that the rail sliding cavity and the guide sliding cavity face each other, the guide defines a pin connected thereto via a flexible cantilever arm, at least a portion of the pin extending into the rail sliding cavity when the rail and the guide are in a sliding relationship for latching by the first and second detents of the rail in providing two predetermined stop positions for the guide.
