Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If coil spring assemblies are used in flexible display devices, then the devices can achieve rolling, expanding, and contracting functions, but the service life is reduced due to shaking and screen pulling or squeezing
Solution Approach 1:
The patent removes the coil spring assembly from the flexible display device structure. By extracting this problematic component, the invention eliminates the source of shaking and screen damage while maintaining the core functionality through alternative means (roller devices and supporting plates).
Solution Approach 2:
The patent divides the flexible display device into distinct functional modules: roller devices for rolling motion, supporting plates for structural support, and transmission mechanisms for coordinated movement. This segmentation allows each component to perform its specific function without causing interference or damage to the flexible screen.
2Weight of moving object
If flexible screens are made thin and lightweight, then portability and flexibility are improved, but the screens become more susceptible to damage during movement
Solution Approach 1:
The patent employs supporting plates positioned beneath the flexible screen to provide preemptive structural support. These plates prevent the thin, lightweight screen from undergoing excessive deformation or damage during rolling and expanding operations, cushioning it against mechanical stress before damage can occur.
Solution Approach 2:
The patent utilizes flexible supporting plates that can deform with the screen while maintaining structural integrity. These plates adapt to the screen's thin and flexible nature while providing the necessary strength to protect against damage during movement operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents the flexible display screens from being pulled or undulated, thereby improving the service life and user experience by ensuring synchronized movement and reducing mechanical stress.
Implementation Method 1
the gear and rack mechanisms can be ensured to operate synchronously in the stretching and contracting processes
Implementation Method 2
Through the transmission manner of the gear and rack mechanisms coordinating with the guy, smooth transmission of the screens in a stretching process or a contracting process is ensured

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.
