UAV Aerial Marker Installation via Automated Cable Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for installing aerial markers on cables are costly, hazardous, and inefficient, particularly due to the need for helicopters and manual wire wrapping, which poses risks to personnel and equipment, and are often impractical in remote or hard-to-reach locations.
Innovation Solution
An automated method using an unmanned aerial vehicle (UAV) with a modified flight control system for reverse thrust and bottom-tether conditions, combined with automatic cable fasteners, proximity sensors, gimbal systems, and cable contact sensors to safely and accurately attach aerial markers to cable spans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If helicopters are used for installing aerial markers, then installation capability in remote locations is improved, but installation cost and safety risks increase
Solution Approach 1:
The patent extracts the hazardous human operator from the installation process by using an unmanned aerial vehicle (UAV) to perform the marker installation. The UAV carries and deploys the aerial marker without requiring a lineman to manually handle equipment near live power lines, thereby eliminating the primary safety risks associated with helicopter-based manual installation while maintaining the ability to reach remote locations.
2Manufacturing precision
If manual wire wrapping methods are used, then installation precision is improved, but installation time and labor cost increase
Solution Approach 1:
The patent employs an automated fastening mechanism carried by the UAV that performs wire wrapping and marker attachment without human intervention. The system includes automated wire feeding, wrapping, and securing mechanisms that operate autonomously once the UAV positions the marker, thereby maintaining installation precision while dramatically reducing the time and labor required compared to manual methods.
Solution Approach 2:
The patent replaces the manual mechanical operations of wire wrapping and marker attachment with an automated mechanical system mounted on the UAV. This system uses motorized wire feeding, automated wrapping mechanisms, and controlled fastening devices to perform tasks that previously required skilled linemen to manually manipulate tools and materials, thereby improving efficiency while maintaining precision through automated control.
3Extent of automation
If climbing robots are used for cable installation, then automation level is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent transitions from ground-based climbing robots that move along the cable to an aerial platform that approaches the cable from above. This dimensional change allows the installation system to operate in three-dimensional space rather than being constrained to the one-dimensional cable surface, simplifying the mechanical interface between the installer and the cable while maintaining high automation through UAV navigation and control systems.
