Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional operation terminals display guidance and driving information uniformly, which can be bothersome for skilled operators as it includes unnecessary information, degrading convenience.

Innovation Solution

An operation assistance method and system that allows switching between displaying and hiding travel state information in specific areas of the operation terminal based on operator preferences, using first and second display areas for essential and optional information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If guidance information and driving information are uniformly displayed on the display device during autonomous travel, then all operators can access the information, but skilled operators find it bothersome due to unnecessary information

Engineering Contradiction:

Improvedisplay adaptabilityVSAvoidoperational convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display device is divided into multiple display areas (first display area and second display area) with different functions. The first display area shows guidance information while the second display area shows driving information, allowing operators to selectively view information based on their needs and skill level.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between different display modes based on the autonomous travel state. During autonomous travel, the system can switch between displaying detailed driving information and simplified guidance information, adapting to real-time operational requirements.

Inventive Principle:

Principle #15Dynamics

2Loss of information

If constant display of guidance information is provided, then operators can always see navigation details, but skilled operators experience degraded convenience due to information overload

Engineering Contradiction:

Improveinformation completenessVSAvoidoperational convenience

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system provides partial information display based on operational context. During autonomous travel, only essential guidance information is displayed in the first display area, while detailed driving information is selectively shown in the second display area only when needed, avoiding information overload for skilled operators.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system automatically adjusts the display content based on the autonomous travel state without requiring manual intervention from operators. The control device autonomously determines what information to display in each area, reducing the cognitive burden on operators.

Inventive Principle:

Principle #25Self-service

AI summary

A display processing unit causes displays a work screen on an operation device that is used for autonomous travel of a work vehicle. The display processing unit displays travel information on a location of the work vehicle in a display area included in the work screen. A setting processing unit switches between a setting to display travel information on a travel state of the work vehicle in display areas included in the work screen and a setting not to display the travel information in the display areas.
