Flexible Display One-Handed Mode Control by Grip Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices with flexible displays face inconvenience when switching from a closed to an opened state in one-handed mode, as the screen extension direction is not adjusted according to the user's grip, making it difficult to control the extended portion.
Innovation Solution
An electronic device with a flexible display and grip sensors on its housings determines the extension direction of the one-handed mode screen based on the user's grip, adjusting the screen display accordingly when transitioning from a closed to an opened state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen is extended in a fixed direction when transitioning from closed to opened state, then the display structure is simple, but the one-handed mode screen becomes difficult to control when the extension direction does not match the user's grip
Solution Approach 1:
The patent applies dynamics by making the screen extension direction adjustable rather than fixed. The system dynamically changes the extension direction based on detected grip patterns, allowing the one-handed mode screen to adapt to different user grips (e.g., left hand vs. right hand, upper grip vs. lower grip). This resolves the contradiction by enabling easy operation across multiple scenarios while using a relatively simple sensor-based detection mechanism.
Solution Approach 2:
The patent changes the parameter of screen extension direction based on grip detection results. When the grip sensor detects different grip patterns (such as gripping position and orientation), the system adjusts the extension direction parameter accordingly. This allows the screen to extend in directions that match the user's grip, improving controllability without requiring complex mechanical structures.
2Ease of operation
If the one-handed mode screen displays at a fixed position, then the display control is simple, but the user experiences inconvenience when having to re-position the screen after switching device states
Solution Approach 1:
The patent applies preliminary action by detecting the user's grip pattern before the screen extension occurs. The grip sensor captures grip information in advance, and the system pre-determines the appropriate extension direction and screen position based on this detected grip state. This eliminates the need for users to manually re-position the screen after state transitions, as the system has already adjusted the screen position proactively based on the detected grip.
Solution Approach 2:
The system uses feedback from grip sensors to automatically adjust screen position and extension direction. The sensor continuously monitors grip patterns, and this feedback information is used to dynamically reposition the one-handed mode screen. This closed-loop approach ensures the screen is always in the optimal position for the current grip, eliminating the time loss associated with manual re-positioning.
3Adaptability or versatility
If grip sensors are added to detect user grip, then the one-handed mode screen can be adapted to user grip, but the device structure becomes more complex
Solution Approach 1:
The patent applies self-service by using the device's existing structural components (housing edges, corners) to serve as grip detection zones. The grip sensors are integrated into the housing structure, utilizing the natural contours and edges that users already contact when gripping the device. This approach enables grip detection and screen adaptation without adding significant structural complexity, as the device structure itself is leveraged for sensing purposes.

AI summary
Disclosed are an electronic device for controlling attributes of one-handed mode screen on the basis of a grip shape and a method for controlling same. An electronic device according to an embodiment of the present document may be configured to display, on a flexible display, a one-handed mode screen which is reduced and displayed according to a predetermined ratio so as to correspond to a first screen, detect, while the one-handed mode screen is displayed, that a first housing is moved, and determine, on the basis of the detection of the movement of the first housing, the direction of expansion of the one-handed mode screen depending on whether a grip of a portion of a user's body on the top portion of the first housing is sensed by a first grip sensor, among grip sensors, which is disposed on the edge of the first housing.
