Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing welded conduit systems on utility and light poles cause wear on cabling due to rough edges and allow insect intrusion, leading to damage and aesthetic issues, while traditional sealing methods are unappealing and hinder maintenance.

Innovation Solution

A Cable Protection Sleeve with split halves that snap together to encase cables, featuring internal bristles for protection against wear and insect penetration, and a rounded edge to prevent cable damage and secure sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welded conduit is used to protect cabling, then cable protection is provided, but rough edges cause cable wear

Engineering Contradiction:

Improvecable protectionVSAvoidcable wear

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent applies a flexible conduit sleeve made of smooth material that covers the rigid welded conduit. This flexible outer layer provides a smooth surface that prevents cable wear while the inner rigid conduit maintains structural protection. The sleeve can be slipped over the conduit and secured, creating a composite protection system that combines the advantages of both rigid and flexible materials.

Inventive Principle:

Principle #30Flexible shells and thin films

2Strength

If welded conduit is used, then cable protection is provided, but insects can still intrude through gaps

Engineering Contradiction:

Improvecable protectionVSAvoidinsect intrusion

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The flexible conduit sleeve acts as a continuous barrier that seals around the cables, preventing insects from entering through gaps between the rigid conduit and cables. The flexible material conforms to the cable shapes and creates a tight seal, while still allowing the rigid conduit to provide structural protection.

Inventive Principle:

Principle #30Flexible shells and thin films

3Object-affected harmful factors

If waxy substance is used to seal gaps, then insect intrusion is prevented, but appearance becomes unappealing and maintenance is difficult

Engineering Contradiction:

Improveinsect intrusion preventionVSAvoidmaintenance accessibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The flexible conduit sleeve is provided as a separate, removable component that can be easily installed and removed without affecting the permanent welded conduit structure. This segmentation allows maintenance personnel to access cables by removing the flexible sleeve, perform maintenance, and reinstall the sleeve, eliminating the need to work around messy sealant.

Inventive Principle:

Principle #1Segmentation

4Object-affected harmful factors

If waxy substance is used to seal gaps, then insect intrusion is prevented, but aesthetic appearance deteriorates

Engineering Contradiction:

Improveinsect intrusion preventionVSAvoidaesthetic appearance

Core Design Contradiction:

Object-affected harmful factorsVSShape

Solution Approach 1:

The flexible conduit sleeve provides a clean, uniform appearance that conceals the messy gap between the rigid conduit and cables. It creates a professional-looking finish that can be selected in various colors to match the pole or conduit, eliminating the unsightly appearance of oozing sealant while maintaining the seal against insects.

Inventive Principle:

Principle #30Flexible shells and thin films
