Shovel Cab Display Layout for Continuous Surroundings Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of shovels face challenges in simultaneously viewing the surroundings and navigating the equipment while accessing menu screens for settings and information, as existing systems often require them to switch between views, disrupting operational visibility.
Innovation Solution
Integration of image capturing devices and a display system within the shovel's cab, allowing operators to view captured images and menu screens simultaneously, with the ability to switch between different image displays without altering the overhead view, enabling continuous operational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device shows a menu screen for settings and information, then the operator can access shovel configurations and data, but the operator cannot simultaneously view the captured image of surroundings, forcing a switch that disrupts operational visibility
Solution Approach 1:
The display device is divided into multiple display regions: a first display region that continuously shows the captured image from the image capturing device, and a second display region that displays the menu screen. This segmentation allows both the menu interface and the situational awareness video feed to be visible simultaneously, eliminating the need to switch between views and maintaining operational visibility while accessing shovel settings and information.
2Adaptability or versatility
If the display device switches between menu screen and captured image, then the operator can access settings, but the operator's view of surroundings is disrupted
Solution Approach 1:
The display device is divided into multiple display regions: a first display region that continuously shows the captured image from the image capturing device, and a second display region that displays the menu screen. This segmentation allows both the menu interface and the situational awareness video feed to be visible simultaneously, eliminating the need to switch between views and maintaining operational visibility while accessing shovel settings and information.
Solution Approach 2:
The captured image display in the first display region continues uninterrupted while the menu screen is displayed in the second region. This continuity ensures that the operator maintains constant situational awareness of the surroundings throughout menu interactions, preventing safety incidents that could occur during view switching.
3Ease of operation
If the display device shows only the menu screen, then the operator can configure settings, but the operator cannot monitor the surroundings simultaneously
Solution Approach 1:
The display device is divided into multiple display regions: a first display region that continuously shows the captured image from the image capturing device, and a second display region that displays the menu screen. This segmentation allows both the menu interface and the situational awareness video feed to be visible simultaneously, eliminating the need to switch between views and maintaining operational visibility while accessing shovel settings and information.

AI summary
A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab mounted on the upper turning body, multiple image capturing devices mounted on the upper turning body, a display device provided in the cab, and an operation part provided in the cab. The display device includes an image display part configured to display a captured image captured by at least one of the image capturing devices and a menu screen. The image display part is configured to display the menu screen while displaying the captured image, in response to the operation part being operated.
