Transparent Display Rear Cover Roller for Tilt-Stable Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with transparent panels lack an efficient mechanism for opening and closing the rear, which can lead to tilting of the cover, compromising visibility and functionality.
Innovation Solution
A display device design that includes a transparent display panel, a cover for the rear, a roller for winding/unwinding the cover, and a drive assembly using wires and a motor to move the cover, minimizing tilting and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is added to the rear of the transparent display panel, then protection and closure functionality are improved, but the risk of tilting increases due to improper mounting structure
Solution Approach 1:
The patent employs a flexible cover that can be wound around a roller, allowing the cover to adapt to the rolling mechanism while maintaining stability. The flexibility enables the cover to be properly positioned and secured without rigid mounting structures that could cause tilting.
Solution Approach 2:
The cover is designed to be dynamically movable through the rolling mechanism, transitioning between opened and closed states. This dynamic design allows for controlled positioning during operation while maintaining stability when closed, preventing tilting issues associated with static mounting.
2Ease of operation
If a rolling mechanism is implemented to open and close the cover, then ease of operation is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent extracts the cover from a fixed mounting structure and attaches it to a rolling mechanism, separating the cover function from rigid structural support. This extraction allows the cover to be operated independently through rolling while simplifying the overall mounting structure.
Solution Approach 2:
The roller acts as an intermediary between the drive assembly (wires and motor) and the cover. This intermediary component translates the linear motion of the wires into rotational motion of the roller, which in turn controls the cover's opening and closing, reducing direct mechanical complexity.
3Extent of automation
If wires and motor are used to drive the roller, then automation level is improved, but manufacturing complexity increases
Solution Approach 1:
The wire assembly is designed to automatically engage with the roller and cover mechanism upon assembly. The wires are configured to naturally route through guides and attach to the roller, reducing the need for complex alignment procedures and manual adjustment during manufacturing.
Solution Approach 2:
The drive system is segmented into modular components: the motor, the wire assembly with guides, and the roller with cover. This segmentation allows each component to be manufactured and tested independently, then assembled together, simplifying the overall manufacturing process while maintaining automated control.

AI summary
A display device is disclosed. The display device includes: a display panel with translucency; a cover disposed at a rear of the display panel; a roller adjacent to one side of the display panel and extending along the one side, the roller around which the cover is wound or from which the cover is unwound; and a drive assembly which moves the cover in a direction away from or toward the one side of the display panel, wherein the drive assembly includes: a first wire adjacent to one end of the cover in a longitudinal direction of the roller, and fixed to the cover; a second wire adjacent to the other end of the cover in the longitudinal direction of the roller, and fixed to the cover; and a motor providing power to the first wire and the second wire.
