Solution Overview

Problem

Conventional techniques for aligning work starting positions in agricultural field operations often result in deviations across different work routes, leading to inconsistent planting patterns.

Innovation Solution

A method and system that involve setting a work starting reference position and adjusting each work starting position based on a predetermined supply interval and route-specific settings to ensure alignment across multiple work routes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional technique aligns work ending position on current travel with work starting position in next work route, then work continuity is improved, but work starting positions deviate across different work routes

Engineering Contradiction:
Improvework continuityVSAvoidwork starting position alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent segments the field into multiple work routes and establishes a common reference position for each route. By dividing the overall positioning task into route-specific segments that all reference the same baseline, the system achieves both continuous workflow and precise alignment across routes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary positioning by establishing a common work starting reference position before actual planting begins. This advance preparation ensures that all subsequent work routes start from precisely aligned positions, eliminating cumulative deviations while maintaining operational continuity.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If work starting position is adjusted for each work route independently, then alignment precision is improved, but system complexity increases

Engineering Contradiction:
Improvework starting position alignmentVSAvoidpositioning system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent creates a universal reference position that serves all work routes simultaneously. This single common reference point performs the alignment function for every route, eliminating the need for multiple independent positioning systems and reducing overall system complexity while maintaining precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent establishes an equipotential reference framework where all work routes originate from the same gravitational baseline (reference position). This creates a unified positioning potential across the entire field, simplifying the positioning system while ensuring consistent alignment precision across all routes.

Inventive Principle:
Principle #12Equipotentiality

AI summary

Provided are a work method, a work system, and a work program that can align a work starting position of each work route in an entire field. An acquisition processing unit 112 obtains a plant interval Lt of agricultural materials. A setting processing unit 115 sets a work starting reference position Px, which is a reference position for setting a work starting position Ps where supply work of the agricultural materials is started, and sets the work starting position Ps corresponding to each of a plurality of work routes on the basis of the plant interval Lt and the work starting reference position Px.
