Solution Overview

Problem

Existing work vehicles require adjustments when a work machine is replaced, and operators may overlook these changes, leading to inappropriate work performance.

Innovation Solution

A method for determining a match or mismatch between past and current work machines attached to the vehicle, with a determination processing unit and notification processing unit to inform the operator of any discrepancies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If work machine replacement is allowed for versatility, then adaptability improves, but work appropriateness deteriorates due to operator oversight

Engineering Contradiction:

Improvework machine replaceabilityVSAvoidwork appropriateness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The control device automatically detects work machine replacement through identifier reading and compares current machine information with stored information. It provides feedback to the operator by displaying notifications when replacement is detected, ensuring the operator is aware of the change and can verify work appropriateness without manual checking

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-monitoring of work machine status and automatic detection of replacements. The control device independently tracks machine identifiers and manages the information comparison process, reducing reliance on operator attention and manual verification procedures

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If manual adjustment procedures are required for work machine replacement, then work customization improves, but operational complexity increases

Engineering Contradiction:

Improvework customizationVSAvoidadjustment procedure simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical adjustment procedures with an automated information processing system. The control device uses identifier reading devices, storage units, and processing algorithms to automatically detect and respond to work machine replacements, eliminating the need for operators to manually track and adjust settings

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The control device acts as an intermediary between the work machine and the operator. It reads machine identifiers, stores information, detects replacements, and communicates with the operator through notifications, simplifying the interaction and removing complex manual adjustment procedures

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

[Problem] To provide a method for controlling a work vehicle, a work vehicle control program, a work vehicle control system, and a work vehicle that easily performs more appropriate work. [Solution] A method for controlling a work vehicle 1 is a method for controlling the work vehicle 1 to which a work machine 400 is detachably attached and includes determining a match/mismatch between first information and second information and notifying a result of determination. The first information is information about a first work machine that is attached as the work machine 400 to the work vehicle 1 at a first time point in the past. The second information is information about a second work machine that is attached as the work machine 400 to the work vehicle 1 at the current time point.
