Flexible Display Lifting Structure Without Multiple Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curled OLED display modules require multiple motors to lift and lower screens, resulting in complex structures and larger sizes, making them inconvenient to carry.
Innovation Solution
A display device with a flexible display screen that uses a chain module, connecting rods, and a screen supporting plate to lift and lower the screen without motors, reducing complexity and size by incorporating a storage component and lifting component within a casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple motors are used to lift and lower the flexible display screen, then the screen lifting and lowering function is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple motor functions into a single lifting component that integrates the chain module, connecting rod, and screen supporting plate. This merging of functions reduces the number of separate motors needed while maintaining the screen lifting and lowering capability, directly resolving the contradiction between operational functionality and device complexity.
Solution Approach 2:
The lifting component is designed as a multi-functional mechanism that can lift and lower the flexible display screen while also providing structural support. The connecting rod and chain module work together to perform multiple functions (lifting, supporting, and stabilizing) that would otherwise require separate components, thereby reducing overall device complexity.
2Ease of operation
If multiple motors are used to lift and lower the flexible display screen, then the screen lifting and lowering function is achieved, but the device size increases
Solution Approach 1:
By merging the lifting, supporting, and stabilizing functions into a single integrated lifting component, the patent reduces the overall volume required for these functions. The chain module and connecting rod are compactly arranged to minimize the space occupied by the lifting mechanism, directly addressing the device size issue.
Solution Approach 2:
The lifting component is designed with nested elements where the chain module is housed within the casing, and the connecting rod is positioned within the space created by the chain module arrangement. This nesting approach minimizes the overall device volume while maintaining full lifting functionality.
3Shape
If the flexible display screen is made scrollable inside the casing, then the curling radius is reduced, but the storage component complexity increases
Solution Approach 1:
The storage component is segmented into functional zones: the flexible display screen is separated from the lifting component, and the chain module is positioned in a dedicated space. This segmentation allows the screen to be curled to a smaller radius without interfering with other components, while the storage component maintains a manageable complexity through organized spatial separation.

AI summary
A display device includes a casing, a flexible display screen, a storage component, and a lifting component. The lifting component includes a chain module, one or more connecting rods, and a screen supporting plate. The chain module is connected to the screen supporting plate, the screen supporting plate is connected to the connecting rod and another end of the flexible display screen. The chain module is connected to the screen supporting plate and configured to drive the screen supporting plate to lift and lower, so that the screen supporting plate drives the flexible display screen and the connecting rod to lift and lower.
