Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the flexible display device uses a simple structure without transmission assembly, then the device complexity is reduced, but the flexible screen is prone to shaking and pulling during rolling, expanding, and contracting processes
Solution Approach 1:
The transmission assembly acts as an intermediary mechanism between the roller device and the flexible screen. It includes a rack that guides the rotating shaft assembly, ensuring that the flexible screen moves smoothly during rolling, expanding, and contracting processes without shaking or pulling, thus improving screen stability while maintaining reasonable device complexity
Solution Approach 2:
The transmission assembly enables dynamic coordination between the roller device and the flexible screen. The rotating shaft assembly, guided by the rack, dynamically adjusts its position and rotation to match the screen's movement, preventing pulling and squeezing while maintaining smooth operation throughout the rolling and expanding cycles
2Reliability
If the flexible display device uses a transmission assembly with rack and rotating shaft, then the screen stability is improved, but the device complexity increases
Solution Approach 1:
The transmission assembly is segmented into distinct functional components: the rack structure that provides guidance, the rotating shaft assembly that provides rotational motion, and the connection mechanisms between them. This segmentation allows each component to perform its specific function efficiently while making the overall system easier to manufacture and maintain
Solution Approach 2:
The rack structure is designed to guide the rotating shaft assembly in advance, preventing any potential pulling or squeezing of the flexible screen before it can occur. The transmission assembly is pre-configured to ensure smooth coordination between components, cushioning against potential damage during the rolling and expanding processes

Implementation Method 1
the transmission assembly includes a pair of racks disposed on a bottom surface of the second supporting plate in parallel, wherein the rotating shaft assemblies are rotatably connected to the racks
Implementation Method 2
a guy, wherein one end of the guy is wound on the rotating shaft assemblies, and another end of the guy is wound on the roller device

AI summary
A flexible display device is provided. The display device includes an outer frame, a first supporting plate, a second supporting plate, a roller device, rotating shaft assemblies, and a transmission assembly. When the second supporting plate and the first supporting plate are expanded relatively or merged with each other, the transmission assembly guides the roller device and the rotating shaft assemblies to rotate simultaneously, ensuring smooth transmission of screens in a stretching process or a contracting process, and improving service life of a flexible display screen.
