Flexible Display Sliding Structure With Motor-Rack Support Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays require an efficient arrangement structure for peripheral components to accommodate sliding housings, particularly for driving modules like motors and racks, to support the transformation of display areas.
Innovation Solution
An electronic device with a flexible display is designed to include a first housing, a second housing that moves relative to the first, a flexible display that moves within the internal space, support members, and a motor with a pinion gear and rack gear system to facilitate the sliding motion of the housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor and rack gear system is added to enable sliding housing movement, then the display area can be expanded and contracted, but the device complexity increases
Solution Approach 1:
The rack gear is integrated with the support member that holds the flexible display, merging the driving function with the support function into a single component. This reduces the number of separate parts while maintaining the ability to expand and contract the display area through motor-driven sliding motion.
2Adaptability or versatility
If the flexible display is made to move within the internal space, then the display area can be variable, but the arrangement structure of peripheral components becomes more difficult
Solution Approach 1:
The flexible display is positioned to move along the longitudinal axis of the device, utilizing the length dimension rather than expanding in width or height. This allows the display area to vary while maintaining a compact cross-sectional profile, making it easier to arrange peripheral components in the transverse directions.
3Adaptability or versatility
If the second housing is made movable relative to the first housing, then the display area can be transformed, but the structural integrity may be compromised
Solution Approach 1:
The housing is divided into two separate housings that can move relative to each other, with the flexible display positioned between them. This segmentation allows independent movement of each housing while maintaining overall structural integrity through the coordinated motion mechanism and support structures.
Solution Approach 2:
The flexible display can be bent into curved or folded configurations during the sliding motion, allowing smooth transformation between extended and retracted states. This curvature capability enables the display to accommodate the relative movement of housings while maintaining structural continuity and integrity.

AI summary
An electronic device is provided. The electronic device includes a first housing, a second housing configured to move with respect to the first housing, a flexible display disposed between the first housing and the second housing, the flexible display including an internal region that at least partially moves within an internal space of the electronic device based on a movement of the second housing with respect to the first housing, a support member including a first support member supporting an end portion of the internal region of the flexible display and a plurality of second support members supporting a portion of the flexible display excluding the end portion, a motor including a pinion gear and disposed in the first housing, and a rack gear engaged with the pinion gear and having an end coupled to the first support member, wherein the rack gear and the first support member move in a same direction as a moving direction of the first housing with respect to the second housing based on driving of the motor.
