Solution Overview

Problem

Existing work systems with multiple work machines struggle to set travel routes with high accuracy, leading to inefficiencies in coordinated work operations.

Innovation Solution

An arithmetic device that sets travel routes for each work machine with a work start point, end point, and intermediate points on a map, ensuring a predetermined width and enclosing the work region with multiple travel routes to enhance accuracy and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple work machines conduct work in cooperation, then work efficiency is improved, but travel route setting accuracy deteriorates

Engineering Contradiction:
Improvework efficiencyVSAvoidtravel route setting accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent divides the work region into multiple segments by setting intermediate points on the outer edge, creating multiple travel routes that enclose the work region. Each work machine is assigned a specific travel route segment, allowing coordinated operation while maintaining precise route definition through systematic division of the overall work area.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If travel routes are set with high accuracy, then work precision is improved, but route complexity increases

Engineering Contradiction:
Improvework precisionVSAvoidroute complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent performs preliminary route planning by setting work start points, end points, and intermediate points on the outer edge before actual work execution. The arithmetic device pre-calculates multiple travel routes that enclose the work region with predetermined width, allowing machines to follow predetermined paths without real-time complex calculations, thus maintaining precision while reducing operational complexity.

Inventive Principle:
Principle #10Preliminary action
