Work Machine Display Guidance for Blind Spot Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machines, such as shovels, do not effectively assist operators by providing information on areas in front of the upper swing structure, leading to reduced operational efficiency and increased risk of accidents.
Innovation Solution
A work machine configuration that includes a lower traveling structure, an upper swing structure, an attachment, a surrounding area monitor, and a display device to present guidance to the operator regarding detected objects in the surrounding area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera is attached to the upper swing structure to capture images of blind spots, then the operator can see areas previously invisible, but the operator still lacks clear guidance on the positional relationship between the attachment and surrounding objects
Solution Approach 1:
The system creates a virtual copy of the real-world scene by capturing images with the camera and superimposing them with graphical information (guidelines and distance indicators) to form a composite display. This virtual representation is shown on the display device, allowing the operator to see both the actual surroundings and the positional relationship with the attachment simultaneously, thereby resolving the contradiction between visibility and operational safety
Solution Approach 2:
The display device acts as an intermediary between the camera's visual information and the operator's decision-making. By processing the camera image and adding graphical overlays (guidelines and distance indicators), the display device mediates the information flow to provide clear positional relationships, transforming raw visual data into actionable guidance that improves operational safety
2Measurement precision
If guidelines are displayed over the camera image to indicate distance, then the operator receives distance information, but the guidance is insufficient for comprehensive spatial awareness
Solution Approach 1:
The system enhances the two-dimensional camera image by adding multiple layers of graphical information that represent three-dimensional spatial relationships. The guidelines and distance indicators are superimposed on the image plane, creating a multi-layered display that conveys depth, distance, and positional relationships simultaneously, thus resolving the contradiction between precise measurement and comprehensive spatial awareness

AI summary
A work machine includes a lower traveling structure, an upper swing structure swingably mounted on the lower traveling structure, an attachment attached to the upper swing structure, a surrounding area monitor, and a display. The display is configured to display guidance with respect to an object detected by the surrounding area monitor.
