Work Vehicle Meter Panel Layout for Dynamic Indicator Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing amount of information displayed on meter panels in agricultural and construction machines reduces visibility, making it difficult for operators to obtain necessary information, especially in smart agriculture and construction site operations.
Innovation Solution
An information display system with a meter panel unit featuring a display and a controller that manages indicator lighting and arrangement based on lighting and extinguishing timings, shifting indicators forward when conditions change, and using analog and digital displays to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If more kinds of information are displayed on the meter panel, then the functionality and information completeness improve, but the visibility and ease of obtaining necessary information deteriorate
Solution Approach 1:
The indicator display region is divided into multiple display positions arranged in order, with each position dedicated to displaying specific indicators. This segmentation allows the system to organize numerous indicators systematically, preventing information overload at any single location while maintaining comprehensive information display across the entire region.
Solution Approach 2:
The display positions of indicators are dynamically adjusted based on lighting and extinguishing timings. When an indicator is extinguished, its display position can be reallocated or shifted to accommodate newly lit indicators, ensuring that the most current and relevant information occupies optimal display positions for operator visibility.
2Loss of information
If the amount of information displayed increases, then the comprehensiveness of vehicle status monitoring improves, but the clarity and readability of individual indicators deteriorate
Solution Approach 1:
By dividing the indicator display region into multiple discrete display positions, each indicator is allocated a specific location rather than being crowded into a single area. This segmentation maintains clear distinction between individual indicators while collectively displaying comprehensive vehicle status information across the entire display region.
Solution Approach 2:
The system transitions from displaying all indicators simultaneously in a single dimension to organizing them across multiple display positions in sequence. This dimensional organization allows comprehensive information display while maintaining readability by distributing indicators across the spatial dimension of the display region.
3Loss of information
If more indicators are displayed simultaneously, then the monitoring coverage improves, but the operator's ability to quickly locate specific information deteriorates
Solution Approach 1:
The display region is segmented into ordered display positions, creating a systematic layout that facilitates quick scanning. Operators can efficiently locate specific indicators by following the ordered sequence of display positions rather than searching through a cluttered, undifferentiated display area.
Solution Approach 2:
Display positions are dynamically adjusted based on indicator lighting patterns. When certain indicators are extinguished, their positions can be repurposed or shifted to highlight currently active indicators, ensuring that operators always see relevant information in prominent positions, thereby reducing information retrieval time.

AI summary
An information display system for a work vehicle includes a meter panel unit including a display, and a controller configured or programmed to control the meter panel unit. The display includes an indicator display region to display a plurality of indicators, each indicating a status of a different component of the work vehicle. The controller is configured or programmed to cause the indicator display region to display one or more indicators among the plurality of indicators that satisfy their lighting conditions, and change an arrangement of the one or more indicators based on lighting and extinguishing timings of each of the plurality of indicators.
