Flexible Display Volume Control via Housing Slide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in enhancing user convenience for volume control while maintaining portability and providing a larger screen.
Innovation Solution
An electronic device with a flexible display that includes a housing, a flexible display that can be exposed or retracted, a speaker, and a processor. The processor controls the speaker to adjust the volume based on the extension or contraction of the flexible display, and the display shows a graphical user interface related to the volume value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is expanded to provide a larger screen, then the portability deteriorates due to increased size and weight
Solution Approach 1:
The patent implements a flexible display that can dynamically change its physical state between folded and unfolded configurations. This allows the display area to expand from a compact folded state to a large unfolded state, providing both portability when folded and large screen area when unfolded, thus resolving the contradiction between display area and device weight/portability.
2Area of stationary object
If the display area is expanded to provide a larger screen, then the portability deteriorates due to increased size
Solution Approach 1:
The flexible display enables the device to transition between compact and expanded states. When folded, the device maintains a small form factor for portability; when unfolded, it provides a large display area for enhanced viewing experience, effectively resolving the contradiction between display area and device size.
Solution Approach 2:
The flexible display is configured to be folded within the housing, allowing the display area to be nested in a compact form when not in use and expanded when needed, similar to a nested doll structure, thus resolving the contradiction between large display area and compact device size.
3Ease of operation
If the volume is automatically adjusted based on display extension, then the user convenience improves, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The system automatically adjusts the volume based on the display extension state without requiring manual user intervention. The processor detects the display state and autonomously controls the speaker volume, providing self-service functionality that improves user convenience while avoiding the need for complex manual control mechanisms.
Solution Approach 2:
The system implements feedback control where the processor continuously monitors the display extension state and adjusts the speaker volume accordingly. This closed-loop feedback mechanism automatically adapts the volume to the current display state, improving user convenience while maintaining relatively simple control architecture through direct state-to-volume mapping.

AI summary
An example electronic device may include a housing, a flexible display, wherein at least a portion of the flexible display which is positioned in the housing is configured to be exposed to an outside of the housing as the housing slides, a speaker, and a processor operatively connected with the speaker and the flexible display. The processor may be configured to control the speaker to output a first sound at a first volume value while a state of the housing is a normal state, identify a size of a first area of the flexible display exposed to the outside, based on a first slide of the housing to change the state of the housing to an extended state, and control the speaker to output the first sound at a second volume value higher than the first volume value based on a size of the first area while the state of the housing is the extended state.
