Work Machine Periphery Display With Variable Caution Zone Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing periphery monitoring systems for large work machines, the small area occupied by the region near the turning radius in bird's-eye view images results in a narrow caution zone, making it difficult for operators to understand the monitoring state efficiently.
Innovation Solution
A periphery display device that creates a bird's-eye view image with varying display magnifications between the turning radius and offset peripheral lines, enhancing the visibility of caution zones by doubling the magnification within the turning radius and maintaining it outside, allowing for easier identification of objects and regions requiring caution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a uniform display magnification is used in the entire bird's-eye view image, then the overall layout is simple and easy to implement, but the caution zone near the turning radius becomes too narrow to be clearly visible
Solution Approach 1:
The patent applies different display magnifications to different regions of the bird's-eye view image. Specifically, the caution zone between the peripheral line and offset peripheral line uses a first display magnification, while the work machine region inside the peripheral line uses a second display magnification. This local differentiation ensures that the caution zone is sufficiently visible without compromising the overall simplicity of the display system.
2Loss of information
If the display magnification in the caution zone is increased to improve visibility, then the caution zone becomes more distinct, but the work machine region may become distorted or difficult to recognize
Solution Approach 1:
The patent carefully selects different magnification values for different regions. The caution zone uses a magnification that enhances visibility of potential hazards, while the work machine region uses a magnification that maintains accurate geometric representation. This selective approach allows each region to be optimized for its specific purpose without compromising the other.

AI summary
There is provided a periphery display device for a work machine, which displays a bird's-eye view image around the work machine. A display magnification of a region between a peripheral line having a turning radius of the work machine and an offset peripheral line surrounding the peripheral line is different from a display magnification of a region inside the peripheral line.
