Solution Overview
Problem
Current electronic devices with flexible display screens face challenges in maintaining structural strength and longevity when expanding the screen, as they are prone to damage during expansion.
Innovation Solution
An electronic device design that includes a flexible display screen, a support plate, and an adjusting mechanism, allowing the support plate to switch between flat and bent states to support the screen, thereby enhancing structural strength and extending the screen's lifespan during expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flexible display screen is used to achieve screen expansion, then the screen area is increased, but the overall structural strength decreases and the flexible display screen becomes easy to damage
Solution Approach 1:
The support structure is divided into multiple support ribs that can independently adjust their positions. Each support rib can be individually controlled to provide localized support to different regions of the flexible display screen, thereby maintaining overall structural strength while accommodating the expanded screen area.
Solution Approach 2:
The support ribs are designed to be adjustable and movable rather than fixed. The adjusting mechanism allows the support ribs to dynamically change their positions and orientations to match the contours of the flexible display screen in different expansion states, providing continuous structural support throughout the range of motion.
2Area of moving object
If a flexible display screen is used to achieve screen expansion, then the screen area is increased, but the flexible display screen becomes easy to damage
Solution Approach 1:
The support ribs are positioned and adjusted in advance to provide support before the flexible display screen undergoes expansion or bending. This preliminary support prevents the screen from experiencing uncontrolled stress and deformation during the expansion process, thereby reducing the risk of damage and improving reliability.
Solution Approach 2:
The adjustable support structure acts as a cushioning mechanism that absorbs and distributes stresses before they can cause damage to the flexible display screen. By providing pre-positioned support, the system mitigates harmful forces during screen expansion and bending operations.
3Strength
If the support plate is made adjustable to support the flexible display screen in different states, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The support structure utilizes thin, flexible support ribs that can bend and conform to the flexible display screen's shape. This approach provides the necessary structural support while maintaining flexibility and avoiding the need for complex rigid mechanical assemblies, thereby reducing overall device complexity.
Solution Approach 2:
The support ribs are designed to change their geometric parameters (position, orientation, curvature) in response to the flexible display screen's state. By adjusting these parameters rather than using complex mechanical linkages, the system achieves adaptable support with simpler mechanics.

AI summary
Electronic device is provided. The electronic device includes a flexible display screen; a support plate, fixedly arranged corresponding to at least part of the flexible display screen; and an adjusting mechanism, for driving the support plate to support the flexible display screen in a first state and driving the support plate to support the flexible display screen in a second state. The first state of the support plate is a flat support state. The second state of the support plate is a bent support state.
