Work Vehicle Meter Panel Layout for Concurrent Fault Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural and construction machines require a meter panel that can display a variety of information with high visibility, as existing systems become cluttered and obscure important data with increased information display needs.
Innovation Solution
An information display system with a meter panel unit featuring a primary region for primary vehicle information and a sub-region for fault notifications, maintenance alerts, and other details, allowing concurrent display without obscuring the primary information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If more kinds of information are displayed on the meter panel, then the information completeness is improved, but the visibility of critical information deteriorates
Solution Approach 1:
The display region is divided into a primary region for critical vehicle information and a sub-region for fault notifications and additional information. This segmentation allows both types of information to be displayed simultaneously without obscuring critical data, resolving the contradiction between information completeness and visibility.
Solution Approach 2:
Different regions of the display are assigned different functional qualities: the primary region maintains high visibility for critical information while the sub-region provides detailed fault information. This local differentiation allows the system to provide comprehensive information while preserving visibility where it matters most.
2Loss of information
If detailed fault notification information is displayed, then the diagnostic information completeness is improved, but the primary vehicle information visibility deteriorates
Solution Approach 1:
The display is segmented into distinct functional zones where the sub-region specifically handles fault notification information while the primary region maintains vehicle operation information. This spatial segmentation ensures that detailed fault information can be displayed without compromising the visibility of primary vehicle information.
Solution Approach 2:
Instead of competing for the same display space, fault information is placed in a separate dimensional space (the sub-region), allowing both primary information and detailed fault notifications to coexist without visual interference, effectively adding a new dimension to the information hierarchy.

AI summary
An information display system for a work vehicle includes a meter panel unit including a display element and a first control device configured to control the meter panel unit. The display element includes a display region including a primary region to display a primary image indicating primary information about the work vehicle, and a sub-region to display a fault notification image notifying a user of details of a fault occurring in the work vehicle or a history of faults that have occurred in the work vehicle in the past. When the first control device displays the primary image in the primary region, and a fault diagnosis result is notified from a second control device configured to perform fault diagnosis of the work vehicle, the first control device, in response to a notification of the fault diagnosis result, displays the fault notification image including a message notifying the details of the fault occurring in the work vehicle in the sub-region while maintaining the primary image in the primary region.
