Foldable Electronic Device Side-Edge Display for Folded-State Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable mobile phones with inward folding screens require users to unfold the device to view shortcut information, leading to inconvenience and reduced service life due to excessive folding.
Innovation Solution
A foldable electronic device with a specific arrangement of display areas, including a fourth display area between the second and third display areas, allowing shortcut information to be displayed and interacted with while the device is folded, reducing the need for frequent unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the foldable mobile phone uses an inward folding screen design, then the device achieves a compact folded form factor, but users cannot view shortcut information without unfolding the device
Solution Approach 1:
The display screen is segmented into multiple independent display areas (first display area, second display area, third display area, fourth display area) that can be arranged in different spatial configurations. The fourth display area is specifically positioned to be visible when the device is folded, allowing shortcut information to be displayed without requiring the device to be unfolded.
Solution Approach 2:
The patent introduces a new spatial dimension for displaying shortcut information by placing the fourth display area on the side edge of the device. This side-edge display area is visible when the device is folded, creating a new viewing dimension that does not require unfolding the main display areas.
2Loss of information
If users frequently unfold the foldable mobile phone to view shortcut information, then they can access the information, but the service life of the device is reduced due to excessive folding cycles
Solution Approach 1:
The fourth display area is pre-configured to display shortcut information (such as time, battery level, and other quick access data) while the device is in the folded state. This preliminary arrangement of information display eliminates the need for users to unfold the device to access frequently viewed information, thereby reducing folding cycles and extending device service life.
3Device complexity
If the foldable mobile phone displays only on the main display areas, then the display structure is simple, but interaction functionality is limited when the device is folded
Solution Approach 1:
The fourth display area serves multiple functions: it displays shortcut information, provides interaction capabilities, and maintains a relatively simple overall display structure. This side-edge display area enables the device to perform multiple functions (information display, user interaction) while remaining in the compact folded state, enhancing adaptability without significantly increasing structural complexity.

AI summary
A foldable electronic device that includes a first display area, a second display area, a third display area, and a fourth display area, when the foldable electronic device is bent inwards to be in a folded state, shortcut information is displayed and interaction is performed using the fourth display area and the third display area to enable a user to view information and perform the interaction without unfolding the foldable electronic device.
