Flexible Touchscreen Icon Transition via Curved Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices with rigid touchscreens limit user interface flexibility, as they cannot adapt to various shapes or folding configurations, restricting the ability to seamlessly transition applications between different screen regions.
Innovation Solution
A mobile device featuring a flexible touch-screen with an external, internal foldable, and curved-surface touch-screen region, where icons can be moved between these regions based on folding angles, allowing for dynamic execution of applications across different screen areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid touchscreen is used in conventional mobile devices, then the device structure is simple and easy to manufacture, but the user interface flexibility and ability to adapt to various shapes is limited
Solution Approach 1:
The touchscreen is divided into multiple independent regions: a first touch-screen region, a second touch-screen region, and a curved-surface touch-screen region coupling them. Each region can be independently controlled and activated based on folding state, allowing flexible user interface adaptation without requiring the entire device structure to be complex.
Solution Approach 2:
The system dynamically activates or deactivates specific touch-screen regions based on the folding angle of the internal foldable touch-screen region. When the folding angle exceeds a threshold, the device transitions between different operational modes, automatically moving icons and adjusting which regions are active, thereby adapting the user interface to the current physical state.
2Adaptability or versatility
If a flexible touch-screen with multiple regions is implemented, then user interface flexibility and adaptability are improved, but the device complexity increases due to additional components and control mechanisms
Solution Approach 1:
The curved-surface touch-screen region serves multiple functions: it couples the first and second touch-screen regions physically, acts as a transition zone for icon movement, and can display content itself when activated. This multi-functional design reduces the need for separate components for each function.
Solution Approach 2:
The curved-surface touch-screen region acts as an intermediary between the first and second touch-screen regions. It facilitates the transition of icons and content between these regions during folding operations, providing a smooth user experience while managing the complexity of the flexible display system.
3Ease of operation
If icons are moved between touch-screen regions based on folding angle, then application switching convenience is improved, but the control mechanism complexity increases
Solution Approach 1:
The system automatically detects the folding angle and autonomously determines which touch-screen region should be active. Icons are automatically moved to appropriate regions based on the folding state without requiring manual user intervention, making the application switching process seamless and convenient.
Solution Approach 2:
The system continuously monitors the folding angle of the internal foldable touch-screen region and uses this feedback to dynamically adjust the active display region. When the folding angle exceeds a predetermined threshold, the system triggers icon movement and region activation/deactivation, creating a responsive control mechanism that adapts to user actions.

AI summary
A mobile device includes a touch-screen having an external touch-screen region, an internal foldable touch-screen region, and a curved-surface touch-screen region that couples the external touch-screen region and the internal foldable touch-screen region, and a body to which the touch-screen is attached, wherein the device is configured to move at least one icon corresponding to at least one executing application program to the curved-surface touch-screen region in response to a folding angle of the internal foldable touch-screen region when a folding operation of the internal foldable touch-screen region is performed.
