Flexible Assembly Limit Structure for Foldable Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small-sized electronic devices have display screens that are too small, necessitating the use of multiple devices for different purposes, which compromises portability and data management due to varying interfaces, batteries, and storage requirements.
Innovation Solution
An electronic device with a flexible assembly and limit structure that allows the display to be expanded or folded, enabling dual-mode operation between a large-sized tablet PC and a small-sized smartphone mode, using a housing with a flexible display, positioning assembly, and a flexible assembly that limits rotation, allowing the device to function as both a large-sized and small-sized screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-sized display screen is used, then the reading horizon and display area are improved, but the volume, weight, and portability deteriorate
Solution Approach 1:
The display system is segmented into a rigid display panel and a flexible support structure that can be independently configured. The flexible assembly includes a flexible circuit board and support frame that can be folded or unfolded, separating the display area function from the structural volume function.
Solution Approach 2:
The flexible assembly introduces dynamic configurability to the device structure. The flexible circuit board and support frame can transition between folded and unfolded states, allowing the display area to dynamically expand or contract while maintaining a compact form factor when folded.
2Adaptability or versatility
If multiple electronic devices are carried, then different display sizes and functions are achieved, but the portability and convenience deteriorate
Solution Approach 1:
The device incorporates universal functionality by integrating both large-screen and small-screen modes within a single device. The flexible assembly enables the same device to function as either a tablet or smartphone depending on its configuration state, eliminating the need for multiple separate devices.
Solution Approach 2:
The dynamic flexible assembly allows the device to transform between different functional modes. By folding or unfolding the flexible circuit board and support frame, the device can switch between tablet mode (large screen) and smartphone mode (small screen), providing versatility without requiring multiple devices.
3Adaptability or versatility
If different operating interfaces and storage devices are used in multiple devices, then specific device functions are optimized, but the data management complexity increases
Solution Approach 1:
The device uses a universal operating interface and storage system that functions consistently across both tablet and smartphone modes. This unified approach eliminates the need for multiple different interfaces and storage devices, simplifying data management while maintaining functional versatility.
4Manufacturing precision
If a flexible assembly with positioning assembly is added, then the rotation control and positioning accuracy are improved, but the device complexity increases
Solution Approach 1:
The positioning assembly acts as an intermediary mechanism between the flexible assembly and the housing. It provides controlled positioning at specific angles (fully folded, partially folded, fully unfolded) without requiring complex continuous control systems, thereby achieving positioning accuracy with moderate complexity.
Solution Approach 2:
The positioning assembly is segmented into discrete positioning points corresponding to different usage modes. Rather than providing continuous adjustment, the system offers specific predetermined positions (tablet mode, smartphone mode, intermediate positions), which simplifies the control mechanism while maintaining sufficient positioning accuracy for each mode.

AI summary
An electronic device with a flexible assembly, comprising a housing, a positioning assembly and a flexible display, is provided. The housing comprises a first cover plate, a second cover plate and a flexible assembly. The flexible assembly is bendably connected to the first and second cover plates, so that the first cover plate closes on the second cover plate or opens to a limit angle with respect to the second cover plate and then stops. The positioning assembly is disposed on the housing for positioning the first cover plate, the flexible assembly and the second cover plate in an open state or a closed state. When the first cover plate opens to the limit angle with respect to the second cover plate, the positioning assembly prevents the first cover plate from rotating in a reverse direction with respect to the second cover plate.
