Solution Overview

Problem

Existing optical fiber racks face difficulties in specifying a desired optical fiber among a large number of fibers, making maintenance and operations challenging due to entanglement and disorganization.

Innovation Solution

The optical fiber rack incorporates a rack part with termination units, an optical fiber housing part with a back plate and first dividing bodies arranged vertically, allowing for easy positioning and separation of optical fiber bundles using first and second dividing bodies and optical fiber guides, preventing entanglement and facilitating selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple optical fiber bundles are housed in the optical fiber housing part, then the quantity of optical fibers increases, but it becomes difficult to specify a desired optical fiber among the large number of fibers

Engineering Contradiction:
Improvequantity of optical fibersVSAvoidease of specifying desired optical fiber
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The optical fiber housing part is divided into multiple sections using first dividing bodies arranged vertically. Each dividing body creates separate holding parts that isolate specific optical fiber bundles, allowing operators to easily locate and specify desired fibers among the large quantity by referring to the segmented structure and corresponding labels.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If optical fiber bundles are densely arranged in the optical fiber housing part, then the space utilization increases, but the optical fiber bundles become entangled

Engineering Contradiction:
Improvespace utilization of housing partVSAvoidorderliness of optical fiber bundles
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

Vertical dividing bodies partition the housing part into distinct sections, preventing optical fiber bundles from entangling while maintaining dense arrangement. Each section holds specific bundles separately, ensuring orderliness is preserved even when space utilization is maximized.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first dividing bodies are arranged in the vertical direction (up-down direction), utilizing the vertical dimension to separate optical fiber bundles horizontally. This dimensional approach allows dense packing while maintaining separation, preventing entanglement through spatial organization in multiple dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the holding part of the first dividing body is positioned closer to the back plate, then the structure is more compact, but the optical fiber bundles cannot be easily positioned and separated

Engineering Contradiction:
Improvestructural compactnessVSAvoidease of positioning and separating optical fiber bundles
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The holding parts of the first dividing bodies are positioned at different distances from the back plate, creating varying depths that facilitate easy positioning and separation of optical fiber bundles. This dynamic positioning allows operators to access and manipulate bundles without compromising the overall compact structure.

Inventive Principle:
Principle #15Dynamics
