Solution Overview

Problem

Existing field-work support terminals cannot effectively manage the progress of work operations, making it difficult for operators to track and oversee the entire work process.

Innovation Solution

A control device equipped with a first acquiring portion for work target regions and a second acquiring portion for worked regions, generating progress information based on this data, and displaying an index to indicate work progress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the field-work support terminal displays work history information, then the operator can review past work data, but the operator cannot grasp the overall work progress against the entire work

Engineering Contradiction:
Improvework progress informationVSAvoidwork progress management
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments work information into distinct components: work history (past data) and work progress (current status). The display control portion separates these functions, allowing work history to be displayed in one area while work progress indicators are shown in another area, enabling the operator to access both types of information simultaneously without confusion

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a work progress indicator as an intermediary element that mediates between the raw work data and the operator's understanding. This indicator serves as a visual bridge that translates complex work status data into easily comprehensible progress information, allowing operators to grasp overall work completion status at a glance

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the field-work support terminal displays detailed work history, then comprehensive work data is available, but it becomes difficult for the operator to manage work progress efficiently

Engineering Contradiction:
Improvework data completenessVSAvoidwork progress management time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The display interface is segmented into distinct functional zones: one for detailed work history and another for work progress indicators. This segmentation allows comprehensive work data to be stored and displayed without overwhelming the operator, as the progress management functions are separated into a dedicated display area with simplified visual indicators

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements partial display of work history information in the progress management area. Instead of showing all detailed work history data in the progress management section, only relevant summary information is displayed, while comprehensive details remain accessible in the dedicated work history area. This partial action approach prevents information overload while maintaining data completeness

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A control device and a work vehicle that an operator can easily manage progress of a work are provided. A control device (80) includes a first acquiring portion (802), a second acquiring portion (803), a generating portion (804), and a display processing portion (86). The first acquiring portion (802) acquires first information on a work target region in which a work vehicle (1) travels and works in a field(98). The second acquiring portion (803) acquires second information on a worked region in which the work vehicle (1) has worked. The generating portion (804) generates progress information indicating progress of a work by the work vehicle (1) on the basis of the first information and the second information. The display processing portion (86) causes an index indicating the progress information to be displayed on the display portion (73).
