Distribution Tie Removal Tool With Multi-Effector Unwinding Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing distribution ties from power lines are unsafe and can damage the conductor, as they often involve using inappropriate tools like knives or screwdrivers, posing risks to linemen and the power lines.
Innovation Solution
A handheld tool with a body and effector portions, featuring a handle, head, bights, and teeth, designed to securely engage and unwind distribution ties from power cables by aligning with the cable's axis and rotating to displace the tie ends, allowing safe and efficient removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specialized tool is designed for removing distribution ties, then lineman safety and protection of power lines is improved, but device complexity increases
Solution Approach 1:
The tool head is divided into multiple effector portions (first, second, third, and fourth effector portions), each with specific geometries designed for different stages of the distribution tie removal process. This segmentation allows each portion to perform a specialized function while collectively solving the overall removal task safely and effectively.
Solution Approach 2:
Different effector portions have different local geometries and properties optimized for specific functions: the first effector portion has a geometry for engaging the distribution tie, the second has a geometry for unwinding it, the third provides support, and the fourth offers additional engagement capability. This local quality differentiation enables the tool to perform multiple operations safely without requiring multiple separate tools.
2Device complexity
If general-purpose tools like knives or screwdrivers are used to remove distribution ties, then device complexity is reduced, but harmful factors increase due to risk of injury and damage
Solution Approach 1:
The tool acts as an intermediary device between the lineman and the distribution tie, providing controlled engagement and removal mechanisms that prevent direct contact with dangerous components. The effector portions serve as intermediaries that safely interact with the distribution tie, eliminating the need for linemen to use inappropriate general-purpose tools that could cause injury or damage.
Solution Approach 2:
The tool's effector portions are designed to preemptively engage and control the distribution tie before removal begins, preventing uncontrolled movement or snapping that could cause harm. The preliminary engagement by the first effector portion secures the distribution tie in a controlled manner, eliminating the safety risks associated with using knives or screwdrivers that lack proper engagement mechanisms.
