Solution Overview

Problem

Current securing mechanisms for cables in communications equipment enclosures, such as cable glands and cable ties, are costly, require skilled installation, and lack flexibility, leading to challenges in configuring networks and manufacturing dedicated solutions that do not adapt to changing market demands.

Innovation Solution

A cable port entry system with inner and outer hooks that engage with optical hardware components, enabling proper routing of cables within fiber optic terminals, and incorporating strain relief assemblies and connector adapters for secure and adaptable installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable glands are used to secure cables at entry points, then cable stability and sealing are improved, but installation cost increases and installer skill requirements increase

Engineering Contradiction:

Improvecable stabilityVSAvoidinstallation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive cable glands with a disposable cable tie system. The cable ties are inexpensive, pre-formed plastic ties that can be easily installed and discarded after use, eliminating the need for expensive reusable cable glands while maintaining cable sec

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If cable glands are used to secure cables, then cable stability is improved, but installer skill requirements and installation time increase

Engineering Contradiction:

Improvecable stabilityVSAvoidinstaller skill requirements

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cable tie system is designed to be self-installing without requiring skilled technicians. The pre-formed cable ties with r-shaped hooks automatically engage with the cable and enclosure features, allowing any installer to secure cables quickly without specialized training or tools

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The cable ties are pre-formed with molded r-shaped hooks and cutting notches during manufacturing. This preliminary preparation eliminates the need for installers to perform complex assembly steps, reducing skill requirements while maintaining secure cable attachment

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If dedicated solutions are manufactured for specific network configurations, then cable routing stability is improved, but adaptability to changing market demands decreases

Engineering Contradiction:

Improvecable routing stabilityVSAvoidadaptability to changing market demands

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The cable tie system with standardized r-shaped hooks and universal mounting features can accommodate multiple cable types, sizes, and routing configurations. The same basic cable tie design works across different network equipment and cable port arrangements, providing both stable cable routing and adaptability to changing market demands

Inventive Principle:

Principle #6Universality (Multi-functionality)
