Innovation Solution

A reforestation machine equipped with a barrier installation device that automatically installs a weed barrier around planted areas, restricting weed growth without requiring significant worker effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If weed barriers are installed manually to restrict weed growth, then plant growth is protected from being hindered, but significant worker effort and time are required

Engineering Contradiction:
Improveweed growth restrictionVSAvoidworker effort
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The reforestation machine performs self-service by automatically installing weed barriers around planted trees through an integrated barrier installation device, eliminating the need for separate manual weed barrier installation operations and reducing worker effort

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent merges the reforestation function (planting trees) with the weed barrier installation function into a single integrated machine, allowing both operations to be performed simultaneously or in sequence without requiring separate manual operations

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If weed barriers are installed manually to protect planted areas, then plant growth is protected, but the installation process is time-consuming

Engineering Contradiction:
Improveweed growth restrictionVSAvoidinstallation time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The barrier installation device is positioned to install weed barriers around newly planted trees immediately after planting, performing the protective action in advance before weeds have a chance to establish, thereby reducing the overall time required for weed management

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The machine maintains continuous operation by seamlessly transitioning between planting trees and installing weed barriers without requiring separate manual intervention, ensuring uninterrupted productive action across the reforestation area

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A reforestation machine includes: a main body; a planting device which plants a plant body for reforestation at a predetermined position of soil; a traveling device which allows the main body and the planting device to travel; a power source which drives the traveling device; and a barrier installation device which installs a weed barrier, restricting the growth of weeds growing around a position in which the plant body is planted, around the predetermined position of the soil.
