Solution Overview

Problem

In existing work machines, displaying an edged image reduces the visible area for state information, potentially decreasing the visibility of critical machine states.

Innovation Solution

A work machine control method that detects targets in a monitoring area and displays a detection object on the screen with a changed display mode based on the detection result, with the object arranged along the outer peripheral edge of the display screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If an edged image is displayed to show detection targets, then detection target visibility is improved, but the visible area for state information is reduced

Engineering Contradiction:
Improvedetection target visibilityVSAvoidvisible area for state information
Core Design Contradiction:
Measurement precisionVSArea of stationary object

Solution Approach 1:

The detection object is positioned along the peripheral edge of the display screen, utilizing the peripheral dimension rather than the central area. This dimensional repositioning allows detection target information to be displayed without occupying the central visible area needed for state information, thereby resolving the contradiction between detection visibility and state information display area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If a detection object is displayed along the peripheral edge, then detection target information is preserved, but visual recognition property may be degraded

Engineering Contradiction:
Improvedetection target information preservationVSAvoidvisual recognition property
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The detection object is displayed using a color different from the background color to enhance visual recognition. This color differentiation ensures that even though the detection object is positioned at the periphery, it remains visually distinct and recognizable, preventing degradation of visual recognition properties while preserving detection target information.

Inventive Principle:
Principle #32Color changes
