Foldable Display Slide Structure for Drop-Induced Screen Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable display devices suffer from deformation and poor display quality when dropped due to the displacement and deformation of middle frame structures, which are only fixed by plastic frames.
Innovation Solution
A display device design that includes a middle frame component with rotatably connected middle frame bodies, a slide component with slidably connected slide elements, and elastic elements that make the slide elements slide away from the gap between the middle frame bodies, thereby maintaining a stretching effect on the display screen during drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display screen is fixed only by plastic frames to the middle frame structures, then the device complexity is reduced and ease of manufacture is improved, but the display screen deforms during the dropping process resulting in poor display quality
Solution Approach 1:
The support structure is segmented into multiple components: plastic frames for basic fixation, slide components with sliding elements for additional support, and elastic elements for dynamic adjustment. This segmentation allows each component to perform its specific function while collectively preventing display screen deformation during drops.
Solution Approach 2:
The slide components are designed to dynamically adjust their position along the sliding direction during the dropping process. The elastic elements enable the slide components to move and adapt to impact forces, maintaining continuous support on the display screen's non-bending region to prevent deformation.
2Reliability
If a slide component with elastic elements is added to apply tensile force on the display screen, then the display screen deformation is prevented, but the device complexity increases
Solution Approach 1:
The slide components act as intermediary elements between the plastic frames and the display screen. These intermediaries provide additional support and dynamic adjustment capability, distributing the support function across multiple components rather than requiring a single complex fixation mechanism.
Solution Approach 2:
The elastic elements change their physical state (compression/expansion) in response to impact forces during dropping. This parameter change allows the support structure to adapt dynamically to varying impact conditions, maintaining display screen stability without requiring complex active control mechanisms.
3Reliability
If the slide elements are designed to slide perpendicular to the gap extending direction, then the tensile force is effectively applied to prevent bending, but the manufacturing precision requirements increase
Solution Approach 1:
The sliding direction is specifically designed to be perpendicular to the gap extending direction at the local level where the slide components interact with the middle frame structures. This local optimization ensures effective tensile force application while the overall structure maintains manufacturing feasibility through standardized component designs.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents deformation and maintains a flat display screen during drops by ensuring the slide component always applies a tensile force to the display screen, preventing bending and deformation.

AI summary
A display device is provided. The display device includes a middle frame component, a slide component, elastic elements, and a display screen. The middle frame component includes at least two middle frame bodies connected rotatably. The slide component includes at least two slide elements. The slide elements are slidably connected to the middle frame bodies correspondingly. The elastic elements are connected between the middle frame bodies and the slide elements. The display screen is connected to the slide component. By disposing the slide component, poor display incurred by occurrence of deformation is prevented when the display screen drops.
