Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor guard structures fail to adequately protect personnel and equipment from dangerous voltages and currents when stringing conductors in energized zones, and are often impractical or difficult to deploy, especially when using crane or boom trucks.
Innovation Solution
An electrically insulated, collapsible boom-mountable temporary conductor guard structure with a U-shaped frame and conductive rollers that supports sagging conductors, mounted on a crane or truck boom, featuring a swivel mechanism for easy deployment and storage, and electrical insulators to prevent grounding hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a boom mounted temporary conductor guard structure is used to catch and support moving conductors, then protection from physical sagging is improved, but electrical insulation from energized conductors is not provided
Solution Approach 1:
The patent introduces electrical insulators as an intermediary component between the boom-mounted conductor guard structure and the boom itself. These insulators create an electrical barrier that prevents harmful current flow from energized conductors to the ground through the boom and equipment, while still allowing the structure to perform its mechanical function of catching and supporting sagging conductors.
2Object-affected harmful factors
If traditional guard structures are used, then electrical protection is provided, but deployment difficulty increases in certain locations
Solution Approach 1:
The patent transforms the static, difficult-to-deploy traditional guard structures into a dynamic, mobile boom-mounted system. The boom can be positioned and adjusted to various locations, making deployment flexible and adaptable to different site conditions. The insulators are integrated into this mobile system, maintaining electrical protection while eliminating the deployment difficulties of fixed structures.
3Ease of operation
If the conductor guard structure is mounted on a crane or boom truck, then ease of deployment is improved, but electrical insulation is compromised
Solution Approach 1:
The patent incorporates electrical insulators as intermediary components between the boom-mounted conductor guard structure and the boom itself. These insulators create an electrical barrier that prevents harmful current flow from energized conductors to the ground through the boom and equipment, while still allowing the structure to perform its mechanical function of catching and supporting sagging conductors.

AI summary
A temporary insulated conductor guard structure is mountable on an electrical insulator. The electrical insulator is mounted on the distal end of a crane or truck boom. The conductor guard structure includes a U-shaped frame having a horizontal elongate beam and a pair of stub arms upwardly extending from opposite ends of the beam. Elongate rigid, electrically conductive rollers are rotatably mounted to each of the stub arms and the beam so as to form an electrically conductive rolling surface extending around the interior of the U-shaped frame for rotationally supporting sagging electrical conductors thereon.
