Flexible Display Panel Winding Mechanism for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices with flexible display panels do not fully utilize the flexibility of the panels, as they are not designed to easily accept and withdraw the display for compact storage, limiting their size reduction and usability.
Innovation Solution
A portable device with a tubular case, a winding drum, and a support system that allows the flexible display panel to be wound and unwound easily, using a rotation driving unit to manage the display's extension and retraction, along with a support mechanism to maintain the panel outside the case for viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display panel is used as a fixed display component, then the display function is stable, but the flexibility and compact storage capability are not utilized
Solution Approach 1:
The display panel is designed to be dynamically extendable and retractable through a sliding mechanism. The panel can be pulled out from the case for viewing and pushed back for compact storage, transforming from a static to a dynamic configuration that adapts to different usage scenarios.
Solution Approach 2:
The display panel is nested within the case when not in use, with the case serving as a protective housing that contains the panel in a compact state. This nesting approach allows the flexible display to be stored efficiently while maintaining easy accessibility when needed.
2Area of stationary object
If the display panel is extended outside the case for viewing, then the display area is increased, but the device becomes unstable and may topple
Solution Approach 1:
The support leg is designed as a dynamic component that can be automatically extended when the display panel is pulled out and retracted when the panel is pushed in. This dynamic adjustment maintains the device's center of gravity and prevents toppling during both extended and retracted states.
Solution Approach 2:
The support mechanism incorporates a feedback system through elastic elements (springs) that sense the position of the display panel and automatically adjust the support leg extension accordingly. When the panel is extended, the spring tension changes, triggering the support leg to extend and provide additional stability.
3Ease of operation
If the support structure is added to maintain display panel outside the case, then the display usability is improved, but the device complexity increases
Solution Approach 1:
The support leg is designed as a self-actuating mechanism that automatically extends and retracts based on the display panel's position without requiring manual intervention. The elastic elements provide the necessary force for automatic adjustment, reducing mechanical complexity while improving usability.
Solution Approach 2:
The support leg serves multiple functions: it provides structural stability when the display is extended, acts as a protective barrier, and helps guide the display panel during extension and retraction. This multi-functionality reduces the need for separate components, thereby limiting overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the flexible display panel to be easily used and stored in a compact form, minimizing the device's overall size and preventing accidental toppling when placed on a surface, while allowing for various applications like cellular phone functions and flashlight use.
Implementation Method 1
a magnet member (41) and a magnetic body (13) corresponding to each other may be provided inside the leading end portion of the support (40) and the concave portion (12) so that the leading end portion of the support (40) is fixed inside the concave portion (12)

AI summary
The present invention relates to a portable device including a flexible display panel and having a new structure in which the flexible display panel is easily accepted and withdrawn to be used. In the portable device including a flexible display panel according to the present invention, when a support (40) is rotated using a rotation driving unit (100), a display panel (30) is withdrawn from a case (10) or the display panel (30) is accepted into the case (10). Therefore, the flexible display panel (30) is easily accepted and withdrawn to be used and since there is a feature that the flexible display panel (30) is wound in the form of rolled paper and maintained in a compact size when not used, there is an advantage capable of minimizing the overall size of the portable device.
