Solution Overview

Problem

Existing cable hangers for above-ground cable configurations in energy production and transmission infrastructures face issues such as displacement during high winds, inadequate bonding, and material deterioration due to UV exposure, leading to potential safety hazards and high costs.

Innovation Solution

A cable hanger design featuring a support member with offset saddles and a hanging mechanism that secures to a support wire, ensuring balanced attachment and preventing rotation, while being made from durable materials to withstand harsh environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable hangers are used in above-ground configurations, then cable support is provided, but displacement during high winds occurs

Engineering Contradiction:

Improvecable support securityVSAvoidhanger position stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The cable hanger system is divided into multiple components: support members with saddles for cable retention, hanging mechanisms for attachment to support wires, and multiple cable hangers spaced along the support wire. This segmentation allows each component to perform its specific function while contributing to overall system stability against wind displacement

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable hangers are pre-installed on support wires before cable installation. This preliminary action ensures that the support structure is already in place to withstand wind loads, preventing displacement before it can occur during operation

Inventive Principle:

Principle #10Preliminary action

2Reliability

If cable hangers are made from durable materials, then resistance to UV deterioration is improved, but material costs increase

Engineering Contradiction:

Improveresistance to UV deteriorationVSAvoidmaterial cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The cable hangers utilize composite construction combining UV-resistant materials for external exposure areas with cost-effective materials for internal or protected areas. This allows the system to achieve necessary UV resistance while controlling overall material costs through strategic material selection in different components

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If hanging mechanism is offset on support member, then rotation is prevented, but device complexity increases

Engineering Contradiction:

Improverotation preventionVSAvoidhanging mechanism configuration

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The hanging mechanism is deliberately positioned offset from the center of the support member, creating an asymmetric configuration. This asymmetry generates a counterbalancing moment that prevents rotation of the cable hanger on the support wire, eliminating the need for additional anti-rotation components and actually simplifying the overall device

Inventive Principle:

Principle #4Asymmetry

AI summary

Systems are provided for a cable hangers. A system for cable hangers can include a cable hanger having a support member including a proximal end and a distal end. A plurality of saddles are attached to and extend from the support member, with each saddle of the plurality of saddles being configured to support at least one cable on a cable supporting surface. A hanging mechanism is arranged at the proximal end of the support member, where the hanging mechanism is offset on the support member.
