Solution Overview

Problem

In existing work machines, operators face challenges in easily and intuitively comprehending the actuation state of the detection processor due to a large amount of information displayed on the display device.

Innovation Solution

A work machine control method that acquires a captured image of the monitoring area and displays it on a display device, with a valid object moving in a virtual circle on the image when the detection processor is enabled, allowing for intuitive visualization of the detection processor's state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a large amount of information is displayed on the display device to show detection processor actuation state, then the information completeness is improved, but the ease of operation deteriorates as operators may miss the actuation state or require constant gazing at the display device

Engineering Contradiction:
Improveinformation completenessVSAvoidease of operation
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent extracts the detection processor actuation state information from the main display screen and presents it through a separate audio output. The speaker outputs a predetermined sound when the detection processor is actuated, allowing operators to perceive the state through hearing rather than requiring visual attention to the display device. This extraction of information to a different sensory channel resolves the contradiction between information completeness and ease of operation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If detailed detection information is displayed on the display screen, then the measurement precision is improved, but the ease of operation deteriorates due to information overload requiring constant monitor gazing

Engineering Contradiction:
Improvedetection accuracyVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces audio output as an intermediary between the detection processor and the operator. Instead of requiring direct visual contact with the display device to understand detection processor state, the speaker acts as a mediator that conveys actuation state through sound. This intermediary allows operators to maintain full awareness of detection status while performing other operational tasks, resolving the contradiction between precise detection information and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

[Problem] To provide a work machine control method, a work machine control program, a work machine control system, and a work machine with which an operator can easily and intuitively comprehend an actuation state of a detector. [Solution] The work machine control method includes: acquiring a captured image Im100 of a monitoring area around a work machine; and displaying a display screen Dp1 including the captured image Im100 on a display device. The work machine control method further includes: in the case where a detection processor for detecting a detection target Ob1 in a monitoring area is enabled, displaying a valid object X1, which moves in at least one of a circumferential direction and a radial direction of a virtual circle centered on a reference point set for the captured image Im100, in a superimposed manner on the captured image on the display screen Dp1.
