Rollable Display Support Structure for Adjustable Screen Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices have fixed, rigid structures that cannot adjust their screen size, making them unsuitable for various applications and programs.
Innovation Solution
A retractable display device with a rollable display screen that can be adjusted in size by rolling and unrolling, featuring a flexible display panel supported by a spine-like structure and mechanisms for smooth deployment and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid fixed structure is used for display devices, then structural stability is improved, but adaptability for different applications and screen sizes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid fixed structure into a retractable mechanism that allows the display screen to extend and retract. The screen can be adjusted from a compact retracted state to an extended viewing state, enabling the same device to adapt to different application scenarios such as portable use, desktop viewing, or large-screen presentations, thereby resolving the contradiction between structural stability and adaptability.
2Area of moving object
If a large screen display device is used, then viewing quality for large audiences is improved, but compactness for storage and transport deteriorates
Solution Approach 1:
The patent implements the nesting principle by designing the display screen to be retractable into the housing body. When not in use, the screen is completely retracted and stored within the compact housing, reducing the device's volume to a portable size. When needed, the screen extends outward to provide a large viewing area, thus resolving the contradiction between screen area and storage volume.
3Ease of manufacture
If the screen size is fixed, then manufacturing simplicity is improved, but versatility for different programs and applications deteriorates
Solution Approach 1:
The patent applies dynamics by implementing a retractable screen mechanism that allows a single device to provide multiple screen sizes. The device maintains manufacturing simplicity by using a unified housing and display assembly, while the retractable mechanism enables versatility for different programs and applications by adjusting the screen extension length, thus resolving the contradiction between manufacturing simplicity and versatility.

AI summary
The disclosure relates to retractable display device (1) including a housing (3) having an internal space (31) defined therein, a rolling axle (32) positioned in the housing (3), an electronic display and a support structure (21) attached to a rear surface of the electronic display. The support structure (21) includes a plurality of juxtaposed support elements (210) capable of being rolled around the axle (32) with the electronic display in a storage position and of being unrolled upward, at least partially out of the housing (3), to provide a substantially planar front surface on which visual information may be displayed.
