Articulating Drone Chainsaw for Stable Remote Branch Trimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trimming tree branches is a dangerous occupation due to the risk of falls, electrocution, and loss of balance when using chainsaws on ladders or extension poles, and existing drones have not been utilized effectively for safe tree trimming.
Innovation Solution
A drone equipped with a chainsaw on an articulating arm, a self-leveling hub, and a rotational pivoting swivel coupling, allowing safe and remote tree trimming by maintaining balance and stability, with a protective cage and multiple motors for stable flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an operator uses a chainsaw on a ladder or extension pole to trim tree branches, then the trimming operation can be performed, but the operator faces high risk of falls, loss of balance, and electrocution
Solution Approach 1:
The patent introduces a drone as an intermediary carrier to transport the chainsaw to the trimming location. The drone flies to the target area and hovers while the chainsaw operates, eliminating the need for the operator to physically position themselves on ladders or extension poles near power lines and falling branches.
Solution Approach 2:
The patent replaces the mechanical system of the operator physically climbing ladders and manually operating the chainsaw with an automated aerial system. The drone's flight control system and automated positioning replace the operator's physical movements, allowing remote operation from ground level.
2Length of moving object
If a chainsaw is placed on an extension pole for remote operation, then the operator can stand at a distance, but the weight of the chainsaw at the end of the pole creates difficulty in control due to extended cantilever effect
Solution Approach 1:
The drone acts as an intermediary that carries the chainsaw wirelessly, eliminating the physical extension pole. The drone's flight control system manages the distance and positioning, removing the cantilever effect that would otherwise make the chainsaw difficult to control.
3Ease of operation
If an operator stands on a ladder while operating a chainsaw, then the trimming operation can be performed, but a fall from the ladder can be catastrophic
Solution Approach 1:
The drone serves as an intermediary platform that carries the chainsaw to the trimming location, allowing the operator to remain on solid ground. This eliminates the need for the operator to climb ladders, thereby removing the risk of catastrophic falls while maintaining the ability to perform tree trimming operations.
Solution Approach 2:
The patent replaces the mechanical system requiring the operator to physically position themselves on elevated structures with an automated aerial delivery system. The drone transports and positions the chainsaw autonomously, substituting the operator's physical presence at height with remote ground-based control.

AI summary
An attachment for an unmanned aerial vehicle (UAV) for trimming tree branches. An articulating arm is mounted to the UAV with a battery powered chain saw positioned along the end of a second articulating arm. The chainsaw allows for the trimming of remote trees and bushes previously only accessible by a ladder or bucket lift. The payload is adjustable forward/aft to maintain the drones center of gravity. The drone includes a remote control receiver, and an antenna allowing an operator to control all aspects of the drone from a remote position.
