Solution Overview

Problem

Existing cutting devices for trimming tree branches are inefficient and lack the ability to remotely and effectively climb the tree, leading to manual labor and increased time for branch removal.

Innovation Solution

A cutting device comprising a collar with movable climbing units that frictionally engage the tree, allowing the collar to spiral upward and downward, equipped with a cutting unit for branch removal, and featuring motors, worm gears, and rollers for controlled movement and cutting, along with a data collection unit for logging yield analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual labor is used for branch removal, then device complexity is reduced, but productivity and time efficiency deteriorate

Engineering Contradiction:
Improvebranch removal efficiencyVSAvoidcutting device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cutting device is divided into distinct functional modules: a collar assembly for tree engagement, climbing units with motors and worm gears for vertical movement, and cutting units with chainsaws for branch removal. Each module operates independently but coordinates through a control system, enabling automated tree climbing and cutting while maintaining manageable complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device employs self-contained climbing units with integrated motors and worm gear mechanisms that automatically ascend and descend the tree without external assistance. The cutting units are positioned and operated autonomously based on collar location, eliminating the need for manual intervention in climbing and cutting operations

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automated climbing mechanism is added, then ease of operation improves, but device complexity worsens

Engineering Contradiction:
Improveremote operation capabilityVSAvoidclimbing mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Manual climbing operations are replaced with automated electrical motors that drive the climbing units up and down the tree. The worm gear mechanisms provide mechanical advantage for vertical movement while allowing easy control through electrical signals, substituting complex manual climbing procedures with simpler remote electrical operation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

A control system acts as an intermediary between the operator and the climbing mechanism, receiving remote commands and translating them into coordinated motor movements. This intermediary layer simplifies operation by abstracting the complexity of the climbing mechanism from the user interface

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of stationary object

If collar spirals upward and downward along tree, then coverage area increases, but device complexity worsens

Engineering Contradiction:
Improvetree coverage areaVSAvoidcollar movement system
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The collar transitions from a static position to a dynamic system that can spiral upward and downward along the tree through coordinated rotation of climbing units. This dynamic movement allows the collar to access multiple heights and positions on the tree, increasing coverage area while the spiral motion pattern provides efficient path planning

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The collar adds vertical dimensionality to its operation by spiraling upward and downward along the tree trunk, transitioning from two-dimensional horizontal coverage to three-dimensional volumetric coverage. This vertical movement capability enables the system to service the entire tree canopy from base to top

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An automated tree cutting assembly includes a collar that may be positioned around a tree. A plurality of climbing units is movably coupled to the collar. The climbing units frictionally engage the tree thereby facilitating each of the climbing units to urge the collar around and up the tree. Each of the climbing units is positionable at selected angle with respect to the collar. Thus, each of the climbing unit units may urge the collar to travel in a spiral along the tree thereby facilitating the collar to climb upwardly and downwardly along the tree. A cutting unit is movably coupled to the collar to cut branches from the tree when the collar is positioned around the tree.
