Solution Overview

Problem

Existing telecommunications enclosures face challenges in efficiently coupling cables to cable ports, particularly in cramped locations, and require complex pressurization systems for sealing, which complicates assembly, maintenance, and structural integrity.

Innovation Solution

A telecommunications enclosure design featuring a base with an outer structure and inner assembly, where sealing modules are removably inserted, allowing cable access without disturbing the outer structure, and enabling individual replacement or closure of cable ports, using elastically deformable elements for sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex pressurization system is used for sealing cable ports, then sealing efficiency is improved, but device complexity and structural integrity are worsened

Engineering Contradiction:
Improvesealing efficiencyVSAvoidpressurization system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base is divided into an outer structure and a removable inner assembly, allowing the sealing function to be separated from the main structural component. This segmentation eliminates the need for complex pressurization systems while maintaining sealing efficiency through simpler elastomeric seals.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner assembly containing the cable ports and seals is extracted as a separate removable component from the outer structure. This extraction allows the sealing mechanism to be simplified and replaced easily without affecting the overall structural integrity of the enclosure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If cable ports are sealed with a unified base structure, then structural integrity is improved, but ease of repair and maintenance are worsened

Engineering Contradiction:
Improvestructural integrityVSAvoidcable port replacement ease
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The base structure is segmented into a permanent outer structure and a removable inner assembly. This allows the outer structure to maintain structural integrity while the inner assembly can be easily removed and replaced for maintenance or repair of cable ports.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner assembly is designed as a disposable or replaceable component that can be removed and replaced without damaging the outer structure. This facilitates easy maintenance and repair while preserving the integrity of the main enclosure structure.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If the entire base is removed for cable access, then ease of operation is improved, but loss of time and productivity are worsened

Engineering Contradiction:
Improvecable coupling easeVSAvoidassembly disassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The base is segmented into an outer structure and an inner assembly, allowing operators to access cable ports by removing only the inner assembly rather than the entire base. This reduces the time and effort required for cable coupling operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner assembly is pre-configured with all necessary cable ports and sealing components, allowing for quick removal and replacement without requiring complex disassembly or reconfiguration during maintenance operations.

Inventive Principle:
Principle #10Preliminary action

4Strength

If sealing modules are permanently integrated into the base, then structural integrity is improved, but adaptability and ease of manufacture are worsened

Engineering Contradiction:
Improvebase structural integrityVSAvoidcable port configuration flexibility
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The base is divided into an outer structure and removable inner assemblies that can be configured differently. This segmentation provides adaptability for different cable port configurations while maintaining the structural integrity of the outer enclosure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outer structure is designed as a universal component that can accommodate different inner assemblies with varying cable port configurations. This multi-functionality allows the same outer structure to support different sealing module arrangements.

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