Tree Shaking Engagement Member for Bark-Safe Branch Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing snow or debris from tree branches are inefficient and difficult to implement, particularly due to the challenge of reaching high branches and the risk of damaging the tree bark.
Innovation Solution
A tree shaking device with an S-shaped engagement member featuring concave regions of varying radii, coupled to a pole via a threaded attachment, allows for automated shaking of branches using a reciprocating saw or similar device, minimizing bark damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If poles and other devices are used to shake branches, then snow and debris can be removed from branches, but the devices may not properly engage the branches
Solution Approach 1:
The engagement member features concave regions with specific radii of curvature that match the local geometry of tree branches. The first concave region has a first radius and the second concave region has a second radius, allowing the device to adapt to different branch sizes and shapes. This localized geometric matching ensures reliable engagement with the branch surface while maintaining effective shaking capability for snow removal.
2Productivity
If conventional shaking devices are used on high branches, then debris can be removed, but it is difficult to reach high branches
Solution Approach 1:
The device is designed to be attached to a pole that serves as an intermediary tool for reaching high branches. The coupling portion of the engagement member connects to the pole, allowing the user to extend their reach to high branches safely without climbing. The pole acts as a mediator between the user and the high branches, enabling effective debris removal from elevated positions.
3Productivity
If branches are shaken to remove snow, then snow removal is achieved, but tree bark may be damaged
Solution Approach 1:
The concave regions of the engagement member are designed with specific radii of curvature that match natural branch geometries, distributing the shaking force evenly across the branch surface. This localized geometric adaptation prevents concentration of stress on specific points, thereby protecting the bark from damage while maintaining effective snow removal capability.
Solution Approach 2:
The engagement member's concave regions are designed to cradle and cushion the branch during the shaking process. The curved surfaces provide a protective interface between the shaking device and the branch, absorbing and distributing mechanical stresses before they can reach the bark, thereby preventing damage while enabling effective snow removal.
