Flexible Display Sliding Mechanism for Compact Device Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In compact electronic devices, flexible displays face challenges in being accommodated and expanded without interfering with internal structures, such as optical sensors, leading to potential damage and operational issues.
Innovation Solution
The design incorporates a sliding mechanism with a flexible display that has a cutout portion to accommodate and expose additional screen area, allowing the display to overlap regions containing electronic components while maintaining light transmission and avoiding mechanical interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a flexible display is partially accommodated inside a compact electronic device, then portability is improved, but the display cannot be expanded without interfering with internal structures
Solution Approach 1:
The flexible display is divided into a first region mounted on the first structure and a second region that can be selectively accommodated in or extracted from the second structure. This segmentation allows the display to be partially stored within the compact device while enabling expansion when needed, resolving the contradiction between portability and display expansion capability.
2Area of moving object
If a flexible display is extracted to expand screen area, then display size is increased, but the display may mechanically interfere with internal structures causing damage
Solution Approach 1:
A second structure is introduced as an intermediary between the flexible display and the first electronic component. This second structure receives and guides the second region of the flexible display during accommodation and extraction operations, preventing direct mechanical interference with the first electronic component while enabling display expansion. The intermediary structure ensures both display size increase and component protection.
3Weight of moving object
If a flexible display is accommodated inside the electronic device, then portability is improved, but the display may overlap and interfere with optical sensor operation
Solution Approach 1:
The second structure is designed with a first face and a second face, creating distinct functional zones. The flexible display's second region is positioned between these faces, allowing it to overlap the first electronic component's location while the structure's geometry ensures light can reach the optical sensor without being blocked by the display. This local structural quality enables both compact accommodation and sensor functionality.
4Weight of moving object
If the electronic device is made smaller for greater portability, then portability is improved, but space for accommodating flexible display is reduced
Solution Approach 1:
The second structure utilizes three-dimensional space by having the flexible display positioned between its first and second faces. This vertical/dimensional arrangement allows the display to be accommodated within a compact footprint while still providing sufficient space for the display's second region. The dimensional arrangement maximizes space utilization, enabling compact device design with adequate accommodation volume.

AI summary
An electronic device is provided, which includes an expanding flexible display. The electronic device includes a first structure including a first face facing a first direction and a second face facing a second direction opposite to the first direction; a second structure that encloses at least a part of the first structure, and configured to guide a sliding movement of the first structure in a direction parallel to the first face or the second face of the first structure; a flexible display including a first region mounted on the first face of the first structure and a second region, which is different from the first region, the second region configured to be accommodated in the second structure or exposed to a first face of the second structure depending on the sliding movement of the first structure; and a first electronic component inside the second structure and exposed through a second face of the second structure, the second face of the second structure facing the second direction and facing away from a first face of the second structure. The flexible display includes an overlapping region at a portion of the flexible display that overlaps a region in which the first electronic component is disposed.
