Solution Overview

Problem

Existing agricultural machines are not suitable for maintaining unharvested crops in a way that prevents undesired or inappropriate travel on the field, leading to potential damage.

Innovation Solution

An agricultural machine equipped with a satellite-based adjustment device that uses tramline information and position data to guide the machine along pre-established tramlines, ensuring it travels within the headland area without damaging unharvested crops, utilizing a tractor and implement with a computing device and data storage for precise navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the agricultural machine travels freely on the agricultural field during maintenance operations, then the machine has operational flexibility, but the unharvested crop in the headland area suffers damage from inappropriate travel paths

Engineering Contradiction:
Improveoperational flexibilityVSAvoidcrop damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system pre-defines valid travel paths (tramlines) before maintenance operations begin. The adjustment device uses these pre-established paths to guide the agricultural machine, preventing crop damage while maintaining operational flexibility through structured navigation options.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adjustment device acts as an intermediary between the operator and the agricultural field. It processes the desired travel path and provides guidance signals to the steering system, mediating between operational flexibility needs and crop protection requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the agricultural machine uses traditional guidance methods without satellite-based adjustment, then the system is simpler, but the machine cannot accurately follow tramlines to prevent crop damage

Engineering Contradiction:
Improvesystem simplicityVSAvoidpositioning accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system replaces traditional mechanical guidance methods with satellite-based GPS/GNSS positioning and electronic control. This substitution enables high-precision tracking of tramlines and headland areas, allowing accurate navigation to prevent crop damage while maintaining relative system simplicity through standardized satellite communication protocols.

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

3Device complexity

If the agricultural machine operates without automated path adjustment, then the control system is less complex, but the machine makes unwanted impacts on unharvested crops in the headland area

Engineering Contradiction:
Improvecontrol system complexityVSAvoidcrop protection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The adjustment device continuously receives satellite-based position information and compares it with the predefined tramline and headland area data. This feedback loop enables real-time path correction and ensures the agricultural machine stays on valid travel paths, reliably preventing crop damage while maintaining manageable control system complexity.

Inventive Principle:
Principle #23Feedback
