Dual-Screen Hinge Structure for Multi-Side Viewing and Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dual-screen displays are limited in their ability to be viewed from multiple sides due to the design of the hinge mechanism, which restricts the opening angle and user experience.
Innovation Solution
A dual-screen display system utilizing a hinge device with bevel gears and connectors that allows the first display screen to rotate until its front surface abuts the front surface of the second display screen and its back surface abuts the back surface, enabling both screens to be positioned on different sides for multiple viewers, with a support for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge device is used to connect two display screens, then the screens can be rotated to different angles, but the shell design limits the opening angle range
Solution Approach 1:
The display device is divided into two independent display screens (first display screen and second display screen) that can be independently adjusted. Each screen has its own support structure, allowing them to be positioned at different angles and orientations without mutual interference, thus achieving multi-angle viewing while avoiding shell structure limitations.
Solution Approach 2:
The patent extends the adjustment from a single plane to multiple dimensions by allowing the first and second display screens to be positioned not only at different angles but also on different sides (front and back). This spatial arrangement enables viewing from multiple directions simultaneously, resolving the contradiction between angle adaptability and structural limitations.
2Adaptability or versatility
If the first display screen rotates to abut against the second display screen, then multiple people can view from different sides, but the rotation mechanism becomes more complex
Solution Approach 1:
The rotation mechanism is segmented into independent support structures for each display screen. The first support supports the first display screen and allows independent rotation, while the second support does the same for the second display screen. This segmentation simplifies the overall mechanism compared to a single complex coupled rotation system.
Solution Approach 2:
The support structures are designed with universal functionality to handle both display screens similarly. Each support can independently rotate and position its associated screen, providing multi-functionality that achieves multi-side viewing without requiring a specially complexed dedicated mechanism for each screen.
3Ease of operation
If dual-screen display is folded in abutting manner, then it becomes convenient to carry, but the hinge device must support both rotation and folding functions
Solution Approach 1:
The folding function is achieved through segmented support structures rather than a traditional hinge. The first and second supports can be independently adjusted and positioned, allowing the device to be folded into a compact abutting configuration for portability while avoiding the complexity of a multi-functional hinge that would need to handle both rotation and folding.
Solution Approach 2:
The support structures are designed to be dynamically adjustable, allowing the display screens to transition between various configurations including the folded abutting position for carrying. This dynamic adjustability provides portability without requiring a fixed complex hinge mechanism, as the supports can be repositioned as needed.

AI summary
The present disclosure discloses a dual-screen display. The dual-screen display includes a first display screen, a second display screen and a hinge device. The first display screen is electrically connected to the second display screen; the first display screen is connected to the second display screen through the hinge device. The first display screen rotates until a front surface of the first display screen abuts against a front surface of the second display screen, and a back surface of the first display screen abuts against a back surface of the second display screen. By using the hinge device, the first display screen can rotate until the front surface of the first display screen abuts against the front surface of the second display screen, and the back surface of the first display screen abuts against the back surface of the second display screen.
