Find Innovative SolutionsGenerate Solutions

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 reference position to ensure alignment across multiple work routes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional techniques align work ending position 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:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent divides the field into multiple work routes and establishes a common reference position for each route. By segmenting the alignment task into route-specific calculations based on a shared reference, the system maintains work continuity while ensuring consistent starting positions across all routes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimensional approach by using a common reference position across all work routes rather than aligning only adjacent routes. This dimensional shift from pairwise alignment to multi-route centralized alignment resolves the contradiction between continuity and precision.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

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 alignmentVSAvoidposition setting system

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent performs preliminary calculation of work starting positions for all routes based on a predetermined common reference position before actual work begins. This advance preparation eliminates the need for complex real-time adjustments during operation, reducing system complexity while maintaining precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a universal reference position that serves all work routes simultaneously. This single reference point enables consistent alignment across multiple routes without requiring separate complex alignment systems for each route, thereby reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An acquisition processing unit obtains a plant interval of agricultural materials. A setting processing unit sets a work starting reference position, which is a reference position for setting a work starting position where supply work of the agricultural materials is started, and sets the work starting position corresponding to each of a plurality of work routes on the basis of the plant interval and the work starting reference position.
