Solution Overview

Problem

The labor-intensive process of installing fiber optic modules and making optical connections in large data distribution centers is inefficient due to the need for technicians to frequently move between the rear and front sections of equipment racks, leading to significant time and labor costs.

Innovation Solution

A fiber optic equipment chassis with a rail guide system that allows fiber optic modules to be installed and connected from the rear section, enabling technicians to guide modules towards the front end, reducing the need for frequent movement and streamlining the installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If fiber optic modules are installed from the front of the equipment rack, then technicians can access and connect modules easily, but technicians must frequently move between the rear and front sections of the rack, increasing installation time and labor

Engineering Contradiction:
ImproveAccess to fiber optic modulesVSAvoidInstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent inverts the conventional installation approach by enabling fiber optic modules to be installed from the rear of the equipment rack rather than the front. The guide system includes rear openings that allow modules to be inserted from the rear, eliminating the need for technicians to walk between the front and rear of the rack during installation.

Inventive Principle:
Principle #13The other way round (Inversion)

2Productivity

If a second technician is used to work in tandem with the first technician, then fiber optic cables can be loaded in the rear while modules are installed from the front, but this increases labor requirements

Engineering Contradiction:
ImproveInstallation efficiencyVSAvoidNumber of technicians required
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The guide system serves multiple functions: it guides modules during rear installation, provides structural support for the modules, and enables single-technician operation. This multi-functionality eliminates the need for a second technician while maintaining installation efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of time

If fiber optic modules are made rear-installable, then technicians can install modules from the rear section reducing movement, but the guide system structure becomes more complex

Engineering Contradiction:
ImproveTechnician movement timeVSAvoidGuide system structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The guide system is segmented into multiple components including guide rails, support structures, and opening mechanisms. This segmentation allows the complex function of rear installation to be achieved through simpler, modular elements that can be manufactured and assembled independently.

Inventive Principle:
Principle #1Segmentation

AI summary

Fiber optic equipment that supports one or more rear-installable fiber optic modules 22) is disclosed. The fiber optic equipment is comprised of a chassis defining a front end and a rear section. At least one guide system is disposed in the chassis and configured to receive at least one fiber optic module. The guide system may be provided in the form of a rail guide system (50). The at least one guide system receives the at least one fiber optic module from the rear section on the chassis and is configured to guide the fiber optic module toward the front end of the chassis. In this manner, a technician can make fiber optic connections to fiber optic modules and also install the fiber optic modules into the fiber optic equipment from the rear section of the chassis to reduce time and/or labor in making fiber optic connections. The rail guide system is provided on a tray (20) to which a hinged routing tray (36) can be attached at the front thereof.
