Work Vehicle Display Device for Urea Water Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles with internal-combustion engines and exhaust gas processing devices may overlook critical information, leading to delayed detection of abnormalities and missed maintenance opportunities due to insufficient or unnoticed display of exhaust gas processing device states.
Innovation Solution
A work vehicle display device that alternates between two images, displaying the same device information related to the exhaust gas processing device's state in similar formats, with the option to switch images via an input device or events, ensuring the operator's attention is drawn to the residual urea water level and any abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display device shows exhaust gas processing device information, then the operator can monitor the device state, but the operator may still overlook the information if it is not sufficiently prominent
Solution Approach 1:
The display control unit alternates between displaying a first image and a second image in a periodic manner. This periodic switching makes the exhaust gas processing device information stand out by changing the display context, thereby drawing the operator's attention without requiring continuous prominent display that would clutter the interface.
Solution Approach 2:
The display system dynamically switches between different image modes (first image during work, second image when not working) based on the work vehicle's operational state. This dynamic adaptation ensures the information is displayed in the most appropriate context, making it more likely to be noticed while maintaining ease of operation.
2Adaptability or versatility
If the display device shows different images for different work states, then the information can be contextually relevant, but the operator may miss information when switching between images
Solution Approach 1:
The display control unit is designed to display the same exhaust gas processing device information in both the first image and the second image, using the same display form. This universal approach ensures that regardless of which image is currently displayed, the critical information remains accessible, combining adaptability to different work states with consistent information availability.
3Loss of information
If the display device prominently shows exhaust gas processing information, then the operator notices it, but the display becomes cluttered and less user-friendly
Solution Approach 1:
Instead of continuously displaying prominent exhaust gas processing information that would clutter the interface, the system uses periodic switching between first and second images. This allows the information to be emphasized at appropriate intervals without permanently increasing display complexity or creating a cluttered interface.

AI summary
A work vehicle display device included in a work vehicle including an internal-combustion engine that generates power and an exhaust gas processing device that processes exhaust gas discharged from the internal-combustion engine using urea water, the work vehicle display device includes: a display unit configured to display an image; and a display control unit configured to display either a first image or a second image different from the first image in the display unit, wherein the display control unit displays device information having a same content related to a state of the exhaust gas processing device in the first image and the second image.
