Quick Release Connector for Utility Power Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively reduce excess loading forces on utility poles during severe weather events, leading to damage and prolonged power restoration times, as they do not adequately interface with existing distribution systems to prevent damage and enable rapid power restoration.
Innovation Solution
A quick release connector that detects and releases power lines from utility poles when a predetermined load is reached, allowing the line to fall to the ground while keeping components attached for easy reattachment, integrating with existing infrastructure without requiring special tools or skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If power lines are permanently fixed to utility poles, then structural stability is improved, but damage occurs during severe weather events due to excess loading forces
Solution Approach 1:
The connector transitions from a static permanent fixation to a dynamic system that can change state based on loading conditions. The quick-release mechanism allows the connector to automatically transition from a locked state (providing structural stability) to an unlocked state (allowing line release) when excessive forces are detected, thereby preventing pole damage during severe weather events.
Solution Approach 2:
The connector is designed to respond to changes in mechanical parameter (force/load) by transitioning between locked and unlocked states. When the applied force exceeds a predetermined threshold, the connector's internal mechanism detects this parameter change and automatically releases the power line, preventing damage to the utility pole while maintaining stability under normal operating conditions.
2Stability of the object's composition
If power lines are permanently fixed to utility poles, then structural stability is improved, but restoration time increases when damage occurs
Solution Approach 1:
The system enables dynamic response to damage conditions by automatically transitioning from a locked to unlocked state when excessive forces are detected. This dynamic capability allows the power line to be quickly released and repositioned without requiring complex repair operations, significantly reducing restoration time while maintaining structural stability during normal operation.
Solution Approach 2:
The quick-release connector enables the power line to be quickly discarded (released) from its fixed position when damage occurs, and then recovered (reattached) to a new location. This process is much faster than traditional permanent fixation methods, allowing utility crews to rapidly restore power by simply repositioning the line rather than performing extensive repairs.
3Productivity
If quick release mechanisms are added to power distribution systems, then rapid power restoration is enabled, but device complexity increases
Solution Approach 1:
The quick-release connector is designed as a self-service mechanism that automatically detects excessive forces and releases the power line without requiring external intervention or complex control systems. The inherent mechanical design includes force-sensing elements and release mechanisms that activate automatically, enabling rapid power restoration while keeping the device relatively simple in construction.

Function Achieved in This Case
The quick release connector effectively reduces damage to poles and power lines, enabling rapid power restoration by releasing lines before excessive tension causes damage, thus minimizing economic and time-related costs associated with power outages.

AI summary
A quick release connector for tensioned power lines, the connector comprising: a first component, said first component attached to a power line segment; and a second component attached to a second generally collinear power line segment, said second component comprising a locking clamp mechanism that selectively clamps the first component and automatically releases upon the application of a longitudinal force of predetermined magnitude along the clamp.
