Adjustable Nonconductive Line Holder for Conductor Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current line holders are stationary and unable to safely move or reposition energized conductors, posing a risk to power line workers due to inadequate clearance and inability to adjust for different angles or heights, leading to potential arc flashes and injuries.
Innovation Solution
A nonconductive line holder with a telescoping shaft and adjustable head, featuring securement points and rollers, allows for safe repositioning of conductors out of the working area, providing adjustable length and angle configurations to enhance worker safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary line holder is used to hold conductors, then the conductor can be secured in place, but the conductor cannot be moved out of the working area, creating safety hazards for workers
Solution Approach 1:
The line holder is designed with a telescoping shaft that can extend and retract, and an adjustable head that can be positioned at different angles and heights. This dynamic structure allows the conductor to be securely held while also being repositioned out of the working area when needed, resolving the contradiction between security and repositioning capability
Solution Approach 2:
The line holder is divided into multiple segments including a telescoping shaft with adjustable sections and a separately adjustable head. This segmentation allows independent adjustment of each component to achieve both secure conductor holding and the ability to move the conductor out of the working area
2Adaptability or versatility
If the line holder structure is made complex with adjustable components, then conductor repositioning capability is improved, but device complexity increases
Solution Approach 1:
The telescoping shaft and adjustable head are designed with mechanical extension and locking mechanisms that provide multiple position options without requiring complex control systems. The adjustability is achieved through straightforward mechanical means that maintain structural integrity while providing versatility
Solution Approach 2:
The line holder allows adjustment of key parameters such as shaft length, head angle, and head height through mechanical means. These parameter changes provide adaptability for different conductor sizes and working conditions while using relatively simple adjustment mechanisms
3Adaptability or versatility
If the line holder is designed to accommodate different conductor sizes and angles, then adaptability is improved, but the device becomes heavier and more complex
Solution Approach 1:
The telescoping shaft can be extended or retracted to accommodate different conductor sizes and positions, and the head can be adjusted to various angles. These parameter adjustments provide versatility without requiring multiple different holder units, thereby avoiding the weight increase that would result from a more robust fixed structure
Solution Approach 2:
The line holder is designed as a universal tool that can handle various conductor sizes and angles through its adjustable components. This multi-functionality is achieved in a single device rather than requiring multiple specialized holders, balancing adaptability with reasonable weight

AI summary
A nonconductive line holder for repositioning a conductor for a line worker to safely work. The line holder has a head, a shaft, and a base. The head is configured to receive and secure a conductor. The shaft can be adjustable or nonadjustable. The base is configured to attach to a base. The line holder attaches to the base and allows a line worker to adjust the positioning of a conductor within the head.
