Solution Overview

Problem

Existing work management systems for work vehicles often result in incomplete work areas due to deviations between planned routes and actual travel paths, requiring manual rework which decreases efficiency and increases operational costs.

Innovation Solution

A work management system equipped with a positioning device to measure the vehicle's position and a control device that creates a rework route for areas where work remains, allowing the vehicle to autonomously perform rework along a planned route, thereby improving workability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If autonomous work is performed along a planned work route, then work efficiency is improved, but deviation between planned route and actual travel path causes remaining work spots

Engineering Contradiction:
Improvework efficiencyVSAvoidroute accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system performs preliminary detection of remaining work spots during autonomous operation, then automatically generates rework routes before manual intervention is needed. This preliminary action eliminates the need for manual rework by preparing the correction path in advance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the actual travel path against the planned work route, detects deviations that create remaining work spots, and automatically generates corrective rework routes. This feedback loop ensures route accuracy is maintained despite autonomous operation variations.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If manual rework is performed for remaining work spots, then work completeness is improved, but workability deteriorates due to increased manual intervention

Engineering Contradiction:
Improvework completenessVSAvoidworkability
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs self-correction by automatically detecting remaining work spots and generating rework routes without manual intervention. The work vehicle autonomously identifies its own incomplete work areas and creates correction paths, eliminating the need for manual rework operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical rework operations with automated electronic route generation and vehicle navigation. The control device substitutes human operators by automatically creating rework routes based on detected remaining work spots, reducing manual labor requirements.

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

AI summary

To provide a work management system for a work vehicle capable of easily performing rework of a spot where work remains even when remaining work occurs to thereby improve workability. A work management system for a work vehicle according to an embodiment is provided with a work vehicle 10 performing work by a work machine 30 while traveling and a control device 100 controlling the work vehicle 10 to work and travel along a planned work route Rw which is previously set by using a measurement result of a positioning device 50, which includes an information terminal 120 receiving an input of information of a spot where work remains A2 at which work remains in a place where work is finished and outputting the inputted information of the spot where work remains A2 to the control device 100, in which the control device 100 creates a rework route R1 for performing rework of the inputted spot where work remains A2 by the work vehicle 10.
