Display Area Allocation for Priority-Based Multi-App Screen Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control devices for vehicles do not efficiently utilize the display area, leading to suboptimal allocation of application areas and potential conflicts when different applications with varying types and priorities are activated.
Innovation Solution
A display control device that includes an obtainer to detect trigger operations for placing second target areas in a display, determining optimal placement without overlapping existing first areas, and managing display-position constraints to allocate areas based on priority and type, using a controller to manage display area usage efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a second target area is placed in a display area that already contains first areas allocated to first applications, then the display area utilization is improved, but area allocation conflicts and overlapping occur
Solution Approach 1:
The display area is segmented into multiple regions (first areas for first applications and second target area for second application). The controller divides the display area into distinct non-overlapping segments, allowing multiple applications to coexist without conflict by allocating specific regions to each application type based on priority and area type.
2Adaptability or versatility
If multiple applications with different types and priorities are allocated to the same display area, then the adaptability of the display system is improved, but the complexity of area management increases
Solution Approach 1:
Different regions of the display area are assigned different qualities or priorities. First areas and second target areas have distinct characteristics based on application type and priority. The controller applies different allocation rules to different regions, allowing high-priority applications to occupy preferred areas while lower-priority applications fill remaining spaces, thereby managing complexity through localized differentiation.
Solution Approach 2:
The system performs preliminary classification of applications by type and priority before allocating display areas. The controller pre-determines which applications should occupy first areas versus second target areas based on their characteristics, and pre-establishes allocation rules for different area types. This preliminary organization simplifies subsequent area management operations.
3Productivity
If the display area is dynamically reconfigured to accommodate different application combinations, then the productivity of the display system is improved, but the stability of existing area allocations deteriorates
Solution Approach 1:
The display area allocation is made dynamic rather than fixed. The controller can reconfigure the display area by replacing first areas with second target areas based on current application requirements, priority levels, and area type classifications. This dynamic adjustment allows the system to optimize display efficiency for different scenarios while maintaining stable allocation rules through the structured first area/second target area framework.

AI summary
A display control device includes: a screen manager that obtains operation information indicating that a trigger operation has been performed to trigger placement of a second target area allocated to a second application in a display area including at least one first area; and a screen generator that determines, when the operation information is obtained, whether to perform the placement, performs the placement without placing the at least one first area in the display area when it is determined to perform the placement, determines, when one of the at least one first applications is different from the second application in type and it is determined to perform the placement, whether to place a second area allocated to the first application in the display area, and places the second area in the display area, when it is determined to place the second area in the display area.
