Solution Overview

Problem

The increasing demand for higher fiber density in telecommunications requires improved mechanisms for securely and efficiently managing tray arrangements within communications panel systems, particularly in terms of latching and cable management, to accommodate higher transmission capacities without compromising accessibility or stability.

Innovation Solution

A latching arrangement that utilizes a cable guide to actuate the latching mechanism, allowing the tray to be releasably held in multiple positions along a forward-rearward axis, with deflection members and biasing members ensuring secure engagement with catch surfaces on the chassis, and magnetically mountable cable guides for enhanced cable management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If trays are made stationary within the chassis, then system stability is improved, but accessibility to port members deteriorates

Engineering Contradiction:
Improvesystem stabilityVSAvoidaccessibility to port members
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The tray is designed to be movable between a retracted position (fully within the chassis) and an extended position (partially outside the chassis). This dynamic configuration allows the tray to transition between stable integration and improved accessibility, resolving the contradiction between system stability and ease of operation.

Inventive Principle:
Principle #15Dynamics

2Productivity

If fiber density is increased to meet transmission demand, then transmission capacity is improved, but complexity of cable management deteriorates

Engineering Contradiction:
Improvetransmission capacityVSAvoidcable management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cable management system is segmented into multiple cable guides that can be independently positioned and configured. Each cable guide can be magnetically mounted at different locations on the tray, allowing cables to be organized and routed efficiently even as fiber density increases, thus managing complexity through modular segmentation.

Inventive Principle:
Principle #1Segmentation

3Reliability

If latching arrangement is made secure with multiple stop members, then reliability of tray positioning is improved, but device complexity deteriorates

Engineering Contradiction:
Improvetray positioning reliabilityVSAvoidlatching arrangement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The latching arrangement utilizes spring-loaded stop members that automatically engage with catch surfaces on the chassis when the tray is inserted. The springs provide automatic biasing force, eliminating the need for additional actuators or complex control mechanisms, thereby achieving reliable automatic positioning with minimal complexity.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables secure and efficient sliding of tray arrangements between retracted and extended positions, improving accessibility and cable management, thereby supporting higher fiber densities and transmission capacities while maintaining system stability and ease of use.

Implementation Method 1

one of the first and second deflection members defines a biasing member to bias the first and second deflection members to neutral positions. Each of the first and second deflection members is moved to a respective actuated position against the bias of the biasing member. In an example, the biasing member includes a leaf spring.

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

one or more cable guides (e.g., front cable guides, rear cable guides, etc.) can be magnetically mounted to the tray arrangement. In certain example, each cable guide holds one or more magnets within respective cavities defined within a body of the cable guide.

Methodology Applied
Scientific EffectMagnetism: Magnetism

AI summary

A latching arrangement by which a tray arrangement is releasably held in one or more positions relative to a chassis is at least partially actuated by a cable guide extending forwardly from the tray arrangement. In some example latching arrangements, the cable guide is pivoted relative to the tray arrangement to release a stop member from the chassis. In other example latching arrangements, the cable guide is slid relative to the tray arrangement to release the stop member. Certain types of latching arrangements have a second stop member that is separately actuated by a different part (e.g., an actuation leg) of the latching arrangement.
