Solution Overview

Problem

Viticulturists face challenges in preserving vine health, particularly in protecting the root network of grape-producing vines from adverse weather conditions, erosion, and nutrient depletion, which existing methods like crop cover are inefficient and costly.

Innovation Solution

An adaptive tillage control system using cutting and casting rotary discs that aerosolizes and casts soil to predetermined areas, adjusting soil displacement based on acceleration, velocity, soil type, and disc angles to provide consistent protection and enhance plant growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If crop cover is planted over root zones to reduce erosion and provide protection, then root protection and erosion control are improved, but labor costs increase and nutrient depletion occurs

Engineering Contradiction:

Improveroot protectionVSAvoidnutrient depletion

Core Design Contradiction:

Object-affected harmful factorsVSLoss of substance

Solution Approach 1:

The patent extracts the protective function from crop covers and transfers it to soil itself by aerosolizing and casting soil over root zones. This eliminates the need for external crop covers that deplete nutrients, while using the soil medium itself to provide the protective barrier against erosion and adverse weather conditions.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an aerosolized soil medium as an intermediary substance that delivers protection to root zones. This aerosol soil acts as a mediator that can be precisely deposited where needed, providing consistent protective coverage without the nutrient depletion issues of traditional crop covers.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If crop cover is used to protect root zones, then erosion control is improved, but labor costs and operational complexity increase

Engineering Contradiction:

Improveerosion controlVSAvoidlabor costs

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical system of planting and maintaining crop covers with an aerosol delivery system that directly deposits soil particles. This substitution eliminates the need for manual crop cover installation and management, significantly reducing labor costs while maintaining effective erosion control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses the vineyard's own soil as the protective material, eliminating the need to import or manage external crop covers. The aerosolized soil is sourced from the same environment, creating a self-sufficient system that reduces operational complexity and labor requirements.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If traditional tillage methods are used, then soil manipulation is achieved, but consistent protective coverage across root zones cannot be provided

Engineering Contradiction:

Improvesoil manipulationVSAvoidprotective coverage consistency

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent transforms soil from a static, bulk material into a controlled aerosol medium with adjustable parameters including particle size distribution, velocity, and deposition density. This parameter control enables precise delivery of consistent protective coverage across varying root zones, overcoming the limitations of traditional tillage methods.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system transitions from static soil manipulation to dynamic aerosol delivery, where soil particles are suspended, transported, and deposited in real-time according to controlled parameters. This dynamic approach allows adaptive adjustment of protective coverage to match the specific needs of different root zones within the vineyard.

Inventive Principle:

Principle #15Dynamics

AI summary

An adaptive tillage control system includes a crossbar, a connecting bar, and cutting and casting rotary discs (discs) that are responsive to an adaptive tillage controller that facilitate angular positioning of the discs. Each disc has a convex outer vertical surface on an exterior side opposite a concave outer vertical surface at its inner side. The discs form a first pair of discs having convex outer vertical surfaces facing outward and a concave outer vertical surface facing inward. The discs also form a second pair of discs having a convex outer vertical surfaces facing outward and the concave outer vertical surface facing inward. The angular positions of the first pair of discs and the second pair of discs are based on a depth sensitivity coefficient that varies with geometric shapes of the discs and varies with the soil type that the discs manipulate.
