Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional terminal enclosures in communication networks limit the number of cables that can enter through ports due to separate entry points for auxiliary wires, which can lead to exposure and deterioration of these wires.

Innovation Solution

A duct port nozzle with an auxiliary wire entry portion that provides a separate entry point for auxiliary wires, using a membrane seal to protect and ground the wires while allowing multiple ducts to be secured to the nozzle, optimizing the use of ports and protecting the wires from environmental exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If auxiliary wires enter through a separate port from ducts, then auxiliary wires can be protected from environmental exposure, but the number of cables that can enter through ports is limited

Engineering Contradiction:

Improveprotection of auxiliary wireVSAvoidnumber of cables entering cabinet

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The duct port nozzle is designed to perform multiple functions: it receives both ducts containing cables and auxiliary wires (such as trace wires or grounding wires) through the same structural component. The nozzle includes a duct receiving portion for cables and an auxiliary wire entry portion for auxiliary wires, allowing a single port structure to accommodate multiple types of wire entries without requiring separate dedicated ports for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the previously separate entry paths for ducts and auxiliary wires into a single integrated duct port nozzle structure. The auxiliary wire entry portion is combined with the duct receiving portion, allowing both cable-containing ducts and auxiliary wires to enter through the same nozzle assembly, thereby optimizing port utilization while maintaining protection for auxiliary wires.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If auxiliary wires enter through a separate port, then cable entry capacity is optimized, but auxiliary wires are exposed to environmental deterioration

Engineering Contradiction:

Improvecable entry capacityVSAvoidenvironmental exposure to auxiliary wire

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The auxiliary wire entry portion includes a membrane seal that provides protection for auxiliary wires while allowing them to pass through. The membrane acts as a flexible barrier that prevents environmental factors (moisture, contaminants) from reaching the auxiliary wires inside the cabinet, while still permitting the wires to enter and be properly terminated.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If multiple separate ports are provided for ducts and auxiliary wires, then protection is improved, but device complexity increases

Engineering Contradiction:

Improveprotection of wiresVSAvoidnumber of ports

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The duct port nozzle is designed as a multi-functional component that consolidates multiple entry functions into a single structure. It simultaneously accommodates duct receiving portions for cable-containing ducts and auxiliary wire entry portions for auxiliary wires, eliminating the need for multiple separate ports while maintaining comprehensive protection for all wire types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention combines previously separate port structures into a single integrated duct port nozzle assembly. The auxiliary wire entry portion and duct receiving portion are merged within the same nozzle structure, reducing the total number of separate ports required while ensuring both cable and auxiliary wire protection through the unified design.

Inventive Principle:

Principle #5Merging (Combining)
