Work Vehicle Display Controller Split Screen Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles face complexity in organizing and accessing large amounts of information on display devices, making it difficult for operators to efficiently and effectively control and maintain vehicle operations.
Innovation Solution
A method and system that utilize a touch screen display with a graphical user interface featuring a launcher icon, which upon selection, displays a first overlay with multiple application icons, allowing for a split-screen view and efficient organization of vehicle information, and returns to a single application view upon subsequent selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large amount of vehicle information is displayed on the touch screen, then the operator has access to comprehensive vehicle features and functions, but the display organization becomes complex and difficult to navigate
Solution Approach 1:
The display interface is segmented into multiple application modules (e.g., vehicle status, diagnostics, maintenance, settings) that can be independently selected and displayed. Each application represents a distinct functional area, allowing the operator to access comprehensive vehicle information while maintaining a simple, organized display structure by showing only one application at a time.
Solution Approach 2:
The patent introduces a temporal dimension to information access through the launcher icon interaction sequence. Instead of displaying all information simultaneously in a complex layout, the system uses sequential display across time (single application view → overlay with multiple applications → selected application view) to provide comprehensive access while maintaining display simplicity at any given moment.
2Adaptability or versatility
If all vehicle applications are displayed simultaneously on the overlay, then the operator can see multiple functions at once, but the display field becomes cluttered and harder to navigate
Solution Approach 1:
The overlay is segmented to display multiple application icons in a structured grid layout, allowing the operator to see available functions while maintaining visual organization. Each application icon represents a distinct functional area, and the segmented layout prevents clutter by providing clear visual separation between applications.
Solution Approach 2:
The overlay displays a limited set of application icons (a partial view of all possible applications) rather than attempting to show every single function simultaneously. This partial display approach maintains versatility by providing access to multiple applications while avoiding the clutter that would result from displaying excessive information at once.
3Adaptability or versatility
If the overlay remains visible continuously, then the operator has quick access to multiple applications, but it obscures the main display field and reduces visibility of the selected application
Solution Approach 1:
The overlay is designed as a dynamic, temporary interface element that appears only during the application selection process and automatically disappears when an application is selected or after a timeout period. This dynamic behavior allows the overlay to provide quick access to multiple applications without permanently obscuring the main display field, as it transitions from visible to invisible based on user interaction.
Solution Approach 2:
The overlay operates on a periodic interaction model: it appears when the launcher icon is activated, remains visible for a limited duration to allow application selection, and then disappears either upon selection or after timeout. This periodic appearance and disappearance pattern ensures that the overlay provides versatility when needed while minimizing obstruction of the main display field during normal operation.

AI summary
A work vehicle including a touch screen display, a work implement movably coupled to a frame, and a control module having a processor and a memory wherein the processor is configured to execute stored program instructions to display a graphical user interface having selectable application icons on one or more overlays. One of the overlays covers a first portion of the display field and a second portion of the display field displays an application selected by one of the selectable application icons. Selection of a split screen icon displays a second overlay on a second portion of the display field.
