Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable electronic devices with flexible displays face issues of creases and tearing due to excessive curvature when rolled up, leading to display damage upon unfolding.
Innovation Solution
A foldable electronic device design incorporating a foldable casing and elastic members that connect the casing and flexible display, allowing for extensibility and preventing stretching-induced damage during folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display is bent along a shaft having a radius greater than the minimal bending curvature, then the device can be folded, but the flexible display will be stretched by the casing and may tear or damage
Solution Approach 1:
The patent uses a flexible display with minimal bending curvature capability, allowing the display to be rolled or folded without creases. The flexible display is designed to bend along a shaft with radius equal to its minimal bending curvature, avoiding stretching and tearing while maintaining display integrity during folding operations.
2Volume of moving object
If the flexible display is rolled up excessively small, then the device volume is reduced, but the flexible display cannot be unfolded normally due to excessive small curvature
Solution Approach 1:
The patent implements a dynamic folding mechanism where the flexible display can be rolled or folded to a compact size while maintaining the ability to unfold. The display is designed with minimal bending curvature requirements that allow compact storage while preserving full unfolding functionality, avoiding permanent deformation or creases.
3Area of stationary object
If a plurality of small-size displays are combined into a large-size screen, then the screen area is increased, but joints are generated and frame quality deteriorates
Solution Approach 1:
The patent uses a single flexible display that can be folded or rolled into segments for compact storage, but when unfolded provides a continuous large-size screen without joints. This eliminates the frame quality deterioration caused by joining multiple displays while maintaining the ability to achieve large screen area when needed.
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 flexible displays to maintain functionality and avoid tearing by providing flexibility, allowing for minimal volume when folded and maximal screen area when unfolded.
Implementation Method 1
the elastic member connects the foldable casing and the flexible display, so as to provide the flexible display the extending flexibility when being unfolded or folded
Data Source
AI summary
A foldable electronic device includes a foldable casing and a flexible display. The flexible display is disposed in the foldable casing, and is connected to the foldable casing through an elastic member, and the elastic member provides the flexible display the extending flexibility when being unfolded or folded together with the foldable casing, such that the flexible display is capable of being used as a display screen of the foldable electronic device.
