Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing telecommunications enclosures require disconnection and re-termination of existing voice and data cabling for retrofit installations, disrupting service and lacking adaptability for mounting over existing equipment or on racks.

Innovation Solution

A telecommunications enclosure system with removable doors and U-shaped perforated knock-outs allows mounting over existing cabling without disconnection, using slotted holes for secure attachment to racks and backboards, enabling full enclosure and airflow management with optional fans for improved security and access control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing telecommunications enclosures are used for retrofit installations, then service continuity is maintained, but adaptability for mounting over existing equipment is limited

Engineering Contradiction:

Improveadaptability for mountingVSAvoidenclosure structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The enclosure is divided into multiple modular components including side walls, top/bottom plates, mounting flanges, and knock-out sections. This segmentation allows the enclosure to be adapted to different mounting configurations (backboard mounting or rack mounting) by selectively assembling components, thereby improving adaptability without significantly increasing overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The enclosure design incorporates universal mounting flanges with multiple hole patterns that can accommodate both backboard mounting and rack mounting applications. The same basic enclosure structure serves multiple functions depending on how the mounting flanges are configured and attached, eliminating the need for completely different enclosure designs for different installation scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If existing cabling is disconnected and re-terminated for enclosure installation, then security and protection are improved, but service interruption occurs

Engineering Contradiction:

Improveservice continuityVSAvoidexposure to damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The enclosure design includes pre-planned knock-out sections and cable access points that are prepared during manufacturing. These pre-defined openings allow cables to be routed through the enclosure walls without requiring disconnection or re-termination of existing connections, thereby maintaining service continuity while still providing protective enclosure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The enclosure acts as an intermediary structure that accommodates existing cabling through dedicated cable access openings and knock-out sections. Rather than requiring direct connection modification, the enclosure provides intermediate pathways for cables to pass through securely, protecting the cabling while maintaining operational continuity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If removable doors are added for security access control, then security is improved, but device complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidenclosure structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The enclosure incorporates removable or hinged doors that can be dynamically opened or closed based on access requirements. This dynamic feature allows the enclosure to transition between secured and accessible states, providing security when needed while allowing easy access for maintenance or cable management without requiring complete structural redesign.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If mounting flanges with multiple aperture options are used for versatile installation, then adaptability is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Improvemounting flexibilityVSAvoidaperture alignment

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mounting flanges are designed as separate, pre-fabricated components with standardized aperture patterns. By segmenting the mounting features into distinct, modular elements, the manufacturing precision requirements are concentrated on individual components rather than the entire enclosure assembly, making high-precision aperture alignment more achievable through standardized production processes.

Inventive Principle:

Principle #1Segmentation

AI summary

Telecommunications enclosure system comprising a first enclosure and second enclosure with each halving a pair of vertical mounting flanges. Bach mounting flange comprises a row of identical round apertures with a slotted aperture disposed at the end of each row of round apertures so that a bolt or screw is used to mount first enclosure to a backboard or equipment rack enclosing pre-selected equipment. The first enclosure further comprising a plurality of U-shaped perforated knock-outs so that existing cabling can be routed outside said first enclosure. The telecommunications enclosure system is configured to mount on an equipment rack having a first side and second side wherein said first enclosure is mounted on said first side of said telecommunications rack and said second enclosure is mounted on said second side of said telecommunications equipment rack so that telecommunications equipment is completely enclosed on all sides thereby preventing unauthorized access.
