Foldable Display Geartrain Hinge for Large Screens and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phone designs, particularly in the pursuit of full-screen displays, face challenges in portability and usability due to increasing screen sizes, power consumption, and lack of innovation, leading to inconvenient multimedia and network applications.
Innovation Solution
A foldable display design featuring a main screen and auxiliary screen connected by a synchronous geartrain mechanism, allowing transformation between folded and unfolded states, maintaining screen length and enabling easy carrying and high-quality display experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen size is increased to improve multimedia and network application experience, then the display quality is improved, but the portability deteriorates
Solution Approach 1:
The display screen is divided into two separate screens (first screen and second screen) that can be independently folded and stacked. This segmentation allows the large total screen area to be achieved while maintaining compact portability when folded, as the two screens can be nested within each other.
Solution Approach 2:
The patent introduces a folding dimension to transform the 2D screen area problem into a 3D spatial solution. By folding the second screen relative to the first screen along a folding line, the device achieves a large unfolded screen area while maintaining a compact folded form factor that fits within the dimensions of a single screen.
2Ease of operation
If a foldable mechanism is introduced to improve portability, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent employs flexible display screens that can be bent and folded without breaking. The flexible nature of the screens themselves serves as the folding mechanism, eliminating the need for complex mechanical hinges or articulation systems while still achieving the desired portability through folding capability.
3Area of moving object
If the screen is made into a whole screen to improve display quality, then the area is improved, but the power consumption increases
Solution Approach 1:
The display is segmented into two separate screens that can be independently controlled. When the device is in folded mode, only the necessary screen area needs to be active, allowing power consumption to be optimized based on the actual usage scenario rather than always powering a large continuous screen area.

AI summary
A foldable display includes a body, a main screen, and an auxiliary screen. The main screen and the auxiliary screen are connected by a foldable mechanism transformable between a folded state and an unfolded state. In the unfolded state, the main screen and the auxiliary screen are sided together to transform into a whole screen.
