Solution Overview

Problem

Optical transition boxes are limited by requiring specific cross-section and size matching with in-line cable ducts, leading to the need for multiple designs and increased dimensions that protrude from building walls, affecting aesthetics and installation efficiency.

Innovation Solution

An optical transition box design that positions adjacent to the in-line cable duct, with the in-line cable entering and exiting through windows in the duct, allowing for reduced box dimensions and using a cable protection cover to manage optical connections between in-line and drop cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the optical transition box contains a portion of the in-line cable duct, then the connection between the duct and box is secured, but the box dimensions increase and multiple designs are required to match different duct cross-sections

Engineering Contradiction:
Improveconnection stabilityVSAvoidduct cross-section compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system is divided into separate functional components: the in-line cable duct remains distinct from the optical transition box, with only the cable (not the duct) passing through. This segmentation allows the duct and box to be independently designed and sized, eliminating the need for multiple box designs to match different duct cross-sections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the in-line cable from the in-line cable duct and routes it through the optical transition box separately. By taking out the cable from the duct and making them independent, the box no longer needs to accommodate or match the duct's cross-section, enabling a standardized box design to work with various duct sizes and shapes.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the optical transition box contains a portion of the in-line cable duct, then the structural integration is improved, but the box protrudes more from the building wall affecting aesthetics

Engineering Contradiction:
Improvestructural integrationVSAvoidprotrusion from wall
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The in-line cable duct is extracted from the optical transition box structure, allowing the box to be positioned closer to the wall without needing to accommodate a large duct portion inside. This reduces the box's protrusion from the building wall while maintaining proper cable routing and connection functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If multiple optical transition box designs are used to match different duct cross-sections, then the fit between duct and box is optimized, but the device complexity and inventory requirements increase

Engineering Contradiction:
Improveduct-box fitVSAvoidnumber of designs
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

A single, standardized optical transition box design is created that can serve multiple functions with different duct cross-sections. By decoupling the box from the duct and using separate cable routing, one universal box design replaces the need for multiple specialized designs, simplifying manufacturing and reducing inventory complexity.

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

Solution Approach 2:

The system segments the duct and box into independent components with standardized interfaces. This allows the box to maintain consistent dimensions and manufacturing specifications regardless of the duct variant, reducing device complexity while maintaining proper integration through standardized cable connection points.

Inventive Principle:
Principle #1Segmentation

AI summary

It is disclosed an optical transition box assembly comprising an optical transition box, the optical transition box comprising a base and a cover. The base comprises two sidewalls. Each of the two sidewalls has a first opening allowing an in-line optical cable to enter the base and to exit said base. The optical transition box assembly further comprises a cable protection cover removably engageable with the base and, when engaged with the base, suitable to cover the first opening of one of the two sidewalls.
