Work Vehicle Route Control for Multi-Part Field Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles equipped with multiple working parts struggle to accurately perform work across the entire target agricultural field, often leaving parts of the field unworked due to the design and operation of the working devices.
Innovation Solution
A work vehicle system that includes a work assistance apparatus capable of setting precise work start and end positions for a working device with multiple parts, allowing the vehicle to travel along a planned route while ensuring all parts of the field are worked efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a working device with multiple working parts is used to perform work while the vehicle travels, then work efficiency is improved, but work coverage accuracy deteriorates causing some parts of the field to be missed
Solution Approach 1:
The system pre-calculates and determines the optimal work start and end positions for each working part before the vehicle begins traveling. This preliminary positioning ensures that when the vehicle moves along the planned route, all working parts will cover their designated areas without missing any sections, thus resolving the contradiction between maintaining high productivity and ensuring complete work coverage accuracy
Solution Approach 2:
The working device is divided into multiple independent working parts, each with its own controlled work start and end positions. This segmentation allows each working part to be precisely positioned and controlled independently, ensuring that even when traveling at high speed, each part maintains accurate work coverage without interfering with others, thereby maintaining both productivity and precision
