Edge Touch Screen Multitasking Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable devices are inconvenient for intuitively switching between application screens, as users must select a previously executed app button to access previously run applications, making it difficult to navigate between multiple open applications.
Innovation Solution
A portable device with an edge touch screen that displays the currently executed application in a main display area and previously executed applications in edge display areas, allowing users to switch screens by touching the edge panel or application drawer, providing visual, audible, and tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat touch screen is used, then the device structure is simple, but the user interaction intuitiveness is poor
Solution Approach 1:
The patent applies curvature to the touch screen by adding an edge touch screen that curves along the side surface of the device. This curved edge screen provides more intuitive user interaction for multitasking operations, allowing users to naturally access previously executed applications through the edge area without needing to return to the main screen center, thus resolving the contradiction between interaction intuitiveness and structural simplicity.
2Productivity
If only a main display area is used, then the display structure is simple, but the multitasking efficiency is low
Solution Approach 1:
The display area is segmented into a main display area and an edge display area. The main display area shows currently executed applications while the edge display area displays previously executed applications. This segmentation allows users to efficiently switch between applications by interacting with the edge area, significantly improving multitasking efficiency without requiring a completely redesigned display structure.
Solution Approach 2:
The patent extends the display functionality from a single main display area to include an additional edge display area along the side surface. This dimensional extension provides a new space for displaying previously executed applications, enabling more efficient multitasking while maintaining the original main display structure for currently executed applications.
3Adaptability or versatility
If a curved edge touch screen is added, then the screen interaction capability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent implements a curved edge touch screen that follows the side surface curvature of the device. This curved screen enhances interaction capability by providing natural edge-access gestures for multitasking. The curvature is designed to match the device's side surface, allowing the curved screen to be integrated as a cohesive structural element rather than a separate complex component, thereby managing manufacturing complexity while enhancing versatility.
