Display Control Layout for Cross-Area Drag-and-Drop Buttons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control devices for in-vehicle systems face challenges in allowing drag-and-drop operations between multiple display areas controlled by different execution layers, while maintaining user-friendly interfaces and minimizing design man-hours.
Innovation Solution
A display control device with a third display control unit that enables drag-and-drop operations between different display areas by displaying specific buttons for user instruction, allowing operations within and between areas, and creating shortcut buttons, thus facilitating user interaction while minimizing design modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display areas are used separately according to execution layer, then design man-hours are reduced and OS modification impact is localized, but drag-and-drop operation across display areas is restricted
Solution Approach 1:
The patent introduces a touch operation area as an intermediary space between separate button arrangement areas. This touch operation area receives drag-and-drop operations from buttons in one display area and transfers them to the corresponding display area, enabling cross-area operations without requiring all buttons to be in a single unified display area. This mediator approach maintains the benefits of separate display area management while restoring user-friendly drag-and-drop functionality.
2Ease of operation
If all operation buttons are displayed in one display area, then drag-and-drop operation is enabled, but design man-hours increase when OS modification is needed
Solution Approach 1:
The patent segments the button arrangement areas into separate display areas corresponding to different execution layers (OS layer and application layer). Each display area independently manages its own buttons, allowing localized modifications when the OS is updated. The touch operation area serves as a bridge that enables drag-and-drop operations across these segmented areas without requiring a unified button arrangement, thus maintaining ease of operation while reducing design man-hours.
3Adaptability or versatility
If multiple display programs with different execution layers are used, then system maintainability is improved, but user interaction across layers becomes complex
Solution Approach 1:
The touch operation area acts as an intermediary that simplifies user interaction across multiple execution layers. Users can perform drag-and-drop operations in the touch operation area without needing to understand or navigate the complex layer structure. The system automatically handles the transfer of operations between display areas corresponding to different execution layers, maintaining simple user interaction while preserving the adaptability benefits of multiple display programs.

AI summary
A display control unit includes: a first display control unit and a second display control unit that display operation buttons in a first display area and a second display area, respectively; and a third display control unit that displays, in the second display area, a first button for instructing a moving operation of the operation buttons in the second display area and a second button for instructing a moving operation of the operation buttons between the first display area and the second display area.
