Flexible Display Middle Frame With Sliding Compensation for Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices experience slippage when bent, leading to a fixed frame size that prevents a frameless setting, as the size of the display device remains unchanged, compromising portability with increasing screen size.
Innovation Solution
A flexible display module middle frame with a bending structure that allows the first and second frames to rotate relative to each other, enabling three states: inward-folded, outward-folded, and unfolded, with sliding connection frames that adjust to compensate for slippage, using bevel gears and transmission components for synchronized motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size middle frame is used to support the flexible display module, then the frame structure is simple and easy to manufacture, but the frame cannot accommodate slippage during bending, preventing a frameless setting and reducing portability
Solution Approach 1:
The middle frame is designed with dynamic characteristics, allowing it to change shape and size during bending operations. The frame includes movable components that enable it to adapt its configuration between folded and unfolded states, transforming from a static structure to a dynamic one that can accommodate the flexible display module's slippage and achieve a frameless setting.
Solution Approach 2:
The middle frame is divided into multiple segments or components that can move relative to each other. This segmentation allows different parts of the frame to independently adjust during bending, with some portions expanding or contracting to compensate for display module slippage, thereby enabling the frameless setting while maintaining structural integrity.
2Reliability
If the frame size is increased to prevent slippage exposure, then the display module is securely supported, but the device size increases and portability decreases
Solution Approach 1:
The frame employs dynamic adjustment mechanisms that allow it to expand or contract based on the bending state. During folding operations, the frame extends to prevent slippage exposure, while in unfolded states, it retracts to minimize device size, thus maintaining reliability without permanently increasing device dimensions.
Solution Approach 2:
The frame components are designed to nest within each other or collapse into a compact configuration when not in use. This nesting capability allows the frame to provide full support during bending operations, then retract to a minimal profile, preventing slippage exposure without permanently increasing the device's overall size.
3Adaptability or versatility
If a fixed middle frame is used, then the manufacturing process is simple, but the frame cannot adjust to different bending states, requiring a larger frame width that compromises portability
Solution Approach 1:
The frame incorporates dynamic elements such as movable joints, sliding components, or articulated structures that enable automatic adjustment to different bending states. These dynamic features allow the frame to adapt its geometry during folding and unfolding operations, providing the required adaptability while maintaining relatively simple manufacturing processes through the use of standardized mechanical components.
