Electromagnet Support for Flexible Display Volume and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current support structures for flexible display screens either fail to reduce volume effectively when folded or lack adequate support when expanded, lacking a solution that simultaneously facilitates volume shrinkage and expanded support.
Innovation Solution
A support structure comprising electromagnets with controlled magnetic poles, where a controller manages the repulsion and attraction of adjacent electromagnets to expand and roll up the flexible display screen, utilizing a flexible panel and electromagnets arranged on the inner surface to secure the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a folding mode support structure is used, then the flexible display screen is conveniently supported when expanded, but it is not easy to reduce the volume after folding
Solution Approach 1:
The support structure transitions from a static folding mechanism to a dynamic rolling mechanism driven by electromagnets. The electromagnets enable the flexible display screen to dynamically change between expanded and rolled states, optimizing both support capability and volume reduction through active control rather than passive mechanical folding.
Solution Approach 2:
The patent replaces traditional mechanical folding support structures with an electromagnetic actuation system. Electromagnets are used to control the rolling and unrolling of the flexible display screen, substituting complex mechanical linkages with a more compact electromagnetic driving mechanism that achieves both support and volume reduction.
2Volume of moving object
If a rolling mode support structure is used, then the flexible display screen can be rolled up with volume shrinkage, but there is no support structure, which is not conducive to supporting the flexible display screen after being expanded
Solution Approach 1:
The electromagnet system serves multiple functions: it acts as both the actuation mechanism for rolling/unrolling and the support structure when expanded. The same electromagnetic components that enable volume shrinkage also provide the necessary support when the flexible display screen is in its expanded state, eliminating the need for separate support structures.
Solution Approach 2:
The patent merges the actuation mechanism and support structure into a single integrated system. The electromagnets are positioned to simultaneously function as the driving force for rolling and as the structural support when expanded, combining what were previously separate functions into one unified mechanism.
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
Enables efficient volume reduction and effective support of the flexible display screen in both expanded and rolled states, enhancing user experience by ensuring stable expansion and tight rolling.
Implementation Method 1
Each electromagnet has a first surface and a second surface. The first surface is configured to be attached and secured to the flexible display screen so as to support the flexible display screen, and the second surface is at an acute angle to the first surface. When the support structure is expanded, the controller is configured to control second surfaces of two adjacent electromagnets to be mutually repelled; when the support structure is bent, the controller is configured to control second surfaces of two adjacent electromagnets to be mutually attracted.
