Flexible Display Sliding Structure With Offset Motor Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with flexible displays, the movement of structures relative to each other, such as slide-in/out operations, require a driving structure that provides strong thrust without increasing the device thickness.
Innovation Solution
The electronic device includes a first housing, a second housing with a rack guiding the sliding, a flexible display with bendable or rollable areas, and a motor that transmits driving force to a gear along the rack, positioned to avoid overlapping the display area, allowing for a slim design and enhanced sliding capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a motor is positioned to provide strong thrust for sliding operations, then the sliding force is improved, but the device thickness increases
Solution Approach 1:
The motor is repositioned from a location that would increase device thickness to a location on the first housing that does not overlap with the flexible display area. This spatial reconfiguration allows the motor to be positioned in a different dimensional arrangement, providing the necessary thrust for sliding operations while maintaining a slim device profile.
Solution Approach 2:
The device is divided into distinct functional zones: the first housing containing the motor and rack, and the second housing containing the flexible display. This segmentation allows the motor to be positioned in the first housing where it can provide strong thrust without interfering with the display area, thereby resolving the contradiction between force generation and device thickness.
2Force
If the motor mounting space is enlarged to accommodate a high-torque motor, then the sliding capability is improved, but the available space for the flexible display is reduced
Solution Approach 1:
The device structure is segmented into two separate housings: the first housing dedicated to housing the motor and rack mechanism, and the second housing dedicated to the flexible display. This clear segmentation allows the motor mounting space to be enlarged in the first housing without encroaching on the display area in the second housing, thus resolving the spatial conflict between motor size and display area.
Solution Approach 2:
The motor is positioned in a location that does not overlap with the flexible display area when viewed from the front, utilizing the depth dimension and lateral spacing to accommodate both the enlarged motor mounting space and the full display area without conflict.

Function Achieved in This Case
This configuration enables stable relative movement and slide-in/out operations of the flexible display while minimizing the device thickness by enlarging the motor mounting space and using a motor with improved torque for sliding.
Implementation Method 1
a motor disposed on the first housing and configured to be capable of sliding relative to the second housing, the motor being configured to transmit a driving force to a gear configured to rotationally move along the rack
