Rollable Display Support Member Guide Groove Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance the mechanical stability and protectiveness of a rollable electronic device while maintaining portability and minimizing the risk of external impact to the display.
Innovation Solution
The electronic device incorporates a support member with a fixed portion under the first display area, a moving portion under the second display area, and a protrusion that inserts into a guide groove in the housing, allowing the support member to slide relative to the housing and providing protection to the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to allow full utilization of multimedia services, then the display area is improved, but the device size increases and portability deteriorates
Solution Approach 1:
The patent implements a rollable display structure where the display panel can dynamically change its effective area by rolling up or extending. The display panel is coupled with a support member that includes a moving portion capable of sliding relative to the housing, allowing the display to transition between a compact rolled state and an extended viewing state, thus resolving the contradiction between large display area and small device size
Solution Approach 2:
The display panel is configured to be rolled into the housing when not in full use, with the support member and guide groove structure enabling the display to nest within the device boundaries. This nesting mechanism allows the large display area to be contained within the compact device form factor, maintaining portability while providing extended display capability when needed
2Adaptability or versatility
If the housing is made movable to enable display rolling operation, then the display flexibility is improved, but the mechanical stability deteriorates
Solution Approach 1:
The support member is divided into a fixed portion and a moving portion that can slide relative to each other along the guide groove. This segmentation allows the display to have flexibility for rolling operation through the moving portion while the fixed portion maintains mechanical stability and structural integrity during the rolling process
Solution Approach 2:
The guide groove acts as an intermediary structure that constrains and guides the movement of the support member. The groove provides a defined path for the moving portion to slide along, ensuring controlled and stable motion while enabling the necessary flexibility for display rolling operation
3Ease of operation
If the display is exposed to the outside in the side surface portion, then the display accessibility is improved, but the vulnerability to external impact increases
Solution Approach 1:
The support member extends to surround at least a portion of the display panel, creating a protective structure before any impact occurs. This support structure acts as a cushioning element that absorbs and distributes external forces, protecting the display from damage while allowing it to remain accessible on the side surface of the device

AI summary
An electronic device can include a first housing, a second housing accommodating a portion of the first housing and including a guide groove formed in a first edge thereof, a flexible display including a first display area arranged on the first housing, and a second display area extending from the first display area. The second display area is configured so as to move on the basis of the sliding movement of the first housing in a first direction; and a support member including a fixed portion arranged below the first display area, a moving portion arranged below the second display area, and a protrusion extending from the moving portion and inserted in the guide groove. The protrusion may include a first area protruding in a second direction perpendicular to the first direction and a second area extending from the first area in a third direction different from the second direction.
