Solution Overview

Problem

Current methods for securing bundles of cables to a purlin, such as using PVC tubing, are costly, labor-intensive, and hinder inspection, replacement, or addition of cables.

Innovation Solution

A cable hanger system comprising support legs, a landing compartment, and securing hooks formed from a single piece of material, allowing secure attachment to a purlin without the need for PVC tubing, enabling easy access and modification of cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If PVC tubing is used to secure cables to a purlin, then the cables are secured, but material costs and labor costs increase

Engineering Contradiction:

Improvecable securingVSAvoidmaterial costs and labor costs

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The cable hanger combines multiple functions into a single integrated component: the body holds cables, the first leg secures to the purlin, and the second leg provides additional support. This eliminates the need for separate PVC tubing and reduces both material costs and installation labor.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cable hanger is designed to be self-installing through its leg structure that directly attaches to the purlin flanges, eliminating the need for additional fastening materials like PVC tubing. The component serves its own securing function without requiring external auxiliary materials.

Inventive Principle:

Principle #25Self-service

2Reliability

If PVC tubing is used to secure cables to a purlin, then the cables are secured, but inspection, replacement, or addition of cables becomes difficult

Engineering Contradiction:

Improvecable securingVSAvoidinspection, replacement, or addition of cables

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cable hanger design allows cables to be individually accessed within the body structure. The open design of the hanger body enables workers to inspect, replace, or add cables without removing the entire securing system, unlike PVC tubing which requires complete removal for any cable modification.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If a single piece of material is formed into a cable hanger with support legs and securing hooks, then device complexity is reduced, but manufacturing precision requirements increase

Engineering Contradiction:

Improvesingle piece structureVSAvoidforming precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The cable hanger is formed from a single piece of material through forming processes that change the material's shape parameters. The design accommodates standard material dimensions and forming capabilities, with the legs and body created through controlled deformation rather than requiring ultra-precise machining, thus balancing simplicity with manufacturability.

Inventive Principle:
