Solution Overview

Problem

Current work management systems cannot perform meticulous management of work time in finer units, such as per ridge, in field farming environments.

Innovation Solution

A work management method and system that determines the operation status and work location of a work device in real-time, outputting a display image associating the device's operation status with the ridge it is working on, and optionally including the following device's position, to provide detailed work information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If work management is performed using conventional methods based on general position information, then overall work monitoring is possible, but meticulous management at the ridge level cannot be achieved

Engineering Contradiction:
Improvework management precisionVSAvoidridge-level work information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The field is segmented into multiple ridges, and the system determines which specific ridge the work device is operating on by matching the device's position with pre-stored ridge position information. This segmentation enables meticulous management at the ridge level rather than treating the entire field as a single unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A work management device acts as an intermediary between the work device and the user. It receives position information from the work device, determines the current ridge by comparing positions, and provides detailed ridge-level work information to the user, thereby bridging the gap between raw position data and meaningful work management information.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If detailed ridge-level work information is provided, then management precision is improved, but system complexity increases

Engineering Contradiction:
Improveridge identification precisionVSAvoidwork management system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Ridge position information is pre-stored in the work management device before work begins. This preliminary preparation allows the system to quickly determine which ridge the work device is on by simple position matching, avoiding the need for complex real-time calculations during actual work operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses position information copying and matching - it compares the current position of the work device with stored ridge position data to determine ridge identity. This copying approach simplifies the determination process compared to complex geometric calculations or machine learning methods.

Inventive Principle:
Principle #26Copying

AI summary

[Problem] For work in a field, management is assisted in a finer unit. [Solution] A work management method includes determining, based on operation information of a work device 30 that performs work in a field 500, an operation status of the work device 30 at each time. The work management method includes determining, based on the operation information of the work device 30, a ridge 510 on which the work device 30 performed work at each time. Furthermore, the work management method includes outputting work information indicating a display image 400, 400B representing the operation status of the work device 30 and the ridge 510 on which the work device 30 performed work in association with each other at each time.
