Rollable Display Housing Extension for Screen Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with rollable displays face challenges in efficiently managing screen sharing and multitasking while maintaining portability and usability.
Innovation Solution
An electronic device with a rollable display and a movable housing that allows for the extension of the display area, enabling the simultaneous display of shared and non-shared screens, with the ability to switch between them based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is expanded using a rollable display, then the screen size is increased, but the device complexity increases
Solution Approach 1:
The display transitions from a static fixed-size screen to a dynamic rollable structure that can expand and contract. The second housing moves between retracted and extended positions, allowing the display area to dynamically change from a first size to a second size, resolving the contradiction between large display area and device complexity by providing adaptability rather than a permanently complex structure
Solution Approach 2:
The display system is segmented into a first display area and a second display area that can be independently controlled. The second housing containing the rollable display is separated from the first housing, allowing independent movement and control of the extended display portion, which simplifies the overall system architecture while achieving expanded display capability
2Area of stationary object
If the second housing is made movable to extend the display, then the display area is increased, but the ease of operation decreases
Solution Approach 1:
The system pre-configures the movable second housing and rollable display mechanism in advance, so that when screen sharing is needed, the display can be quickly extended to a second size. The housing and display components are pre-positioned and prepared, reducing the operational complexity during actual use
Solution Approach 2:
The movable second housing serves multiple functions: it contains the rollable display, provides structural support for the extended display area, and enables both screen sharing mode (when extended) and portable mode (when retracted). This multi-functionality reduces the need for separate components, simplifying operation
3Adaptability or versatility
If the display is extended for screen sharing, then the multitasking capability is improved, but the portability decreases
Solution Approach 1:
The display system dynamically adapts its size based on usage requirements. For multitasking and screen sharing, the second housing extends to provide a larger second display area. For portability, the second housing retracts to minimize the device length. This dynamic adaptability resolves the contradiction by allowing the device to optimize its physical dimensions according to the current operational context
Solution Approach 2:
The rollable display and second housing are nested within the first housing when not in use, similar to a nested doll structure. The extended display components can be stored inside the main body, allowing the device to maintain a compact form factor for portability while being capable of expanding to a larger configuration for multitasking and screen sharing applications

AI summary
An electronic device is provided. The electronic device includes a first housing, a second housing disposed to be movable with respect to the first housing, a rollable display inserted into the first housing or withdrawn from the first housing based on sliding-in or sliding-out of the second housing, a motor driving module disposed inside the first housing or the second housing and configured to move the second housing in a first direction or a second direction, communication circuitry, at least one processor, and memory storing instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to display a first screen in an exposed area of the rollable display, move the second housing in the second direction so that the exposed area of the rollable display is extended, display a shared screen shared with an external electronic device, in a first area corresponding to an exposed area before the rollable display is extended, of extended exposed area,, based on a user input received through the first screen, and transmit information, related to the shared screen, to the external electronic device through the communication module.
