Solution Overview

Problem

Users of electronic devices face inconvenience when switching from a closed to an opened state in one-handed manipulation mode due to the need for repositioning the screen, especially when a flexible display is extended vertically, making it difficult to control the upper end of the screen.

Innovation Solution

An electronic device that controls the properties of a one-handed mode screen based on the user's grip, determining the extension direction of the screen to minimize user inconvenience during transitions from a closed to an opened state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the flexible display is extended in the vertical direction when switching from closed to opened state, then the display area is increased, but the one-handed mode screen extends toward the upper end making it difficult for the user to control

Engineering Contradiction:
Improvedisplay areaVSAvoidcontrol accessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the one-handed mode screen position adjustable rather than fixed. The screen can dynamically change its position between upper and lower ends based on the extension state of the flexible display, allowing the system to adapt to different usage scenarios and maintain ease of operation throughout the transition from closed to opened state.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of screen position (upper end vs. lower end) based on the extension state of the flexible display. When the display is extended, the system switches the one-handed mode screen from the upper end position to the lower end position, thereby maintaining user accessibility while preserving the increased display area.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the one-handed mode screen is displayed at the last used position, then the display position is maintained for consistency, but the user experiences inconvenience when the extension direction opposes the grip direction

Engineering Contradiction:
Improvedisplay position consistencyVSAvoiduser convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent makes the one-handed mode screen position dynamic rather than statically maintaining the last used position. The system detects the user's grip state and flexibly adjusts the screen position between upper and lower ends, allowing the display to adapt to the user's current hand position while maintaining operational convenience.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system automatically detects the user's grip state and autonomously adjusts the one-handed mode screen position without requiring manual intervention. The electronic device serves itself by monitoring grip sensors and automatically repositioning the screen to the appropriate end, thereby maintaining both consistency and user convenience.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the housing slides from closed to opened state during one-handed manipulation, then the device functionality is enhanced, but the one-handed mode screen extends making it difficult to control

Engineering Contradiction:
Improvedevice functionalityVSAvoidscreen control
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by linking the one-handed mode screen position to the housing extension state. When the housing slides from closed to opened state, the system dynamically switches the screen position from upper end to lower end, ensuring that the screen remains accessible despite the physical transformation of the device.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary action by detecting the housing extension state in advance and proactively adjusting the one-handed mode screen position before the user encounters control difficulties. This anticipatory adjustment ensures seamless transition and maintains ease of operation throughout the sliding process.

Inventive Principle:
Principle #10Preliminary action

AI summary

Disclosed are an electronic device for controlling properties of a one-handed mode screen according to grip types and a method for controlling the same. The electronic device according to an embodiment herein may be configured to display, on the flexible display, a one-handed mode screen that is reduced and displayed according to a predetermined ratio corresponding to a first screen, detect that a second housing is moved with respect to a first housing while the one-handed mode screen is displayed, and determine, based on the detection of the movement of the second housing, the extension direction of the one-handed mode screen according to whether a first grip sensor disposed at the edge of the first housing among the grip sensors senses that a user's body portion grips an upper end of the first housing.
