Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable display devices face challenges in achieving a larger display area while maintaining portability, as they occupy significant space and require complex connection components that increase production costs and reduce efficiency.
Innovation Solution
A foldable display device design combining a foldable flexible display screen with a stretchable screen, featuring a rewinding component that provides elastic pulling force, allowing for a larger display area when unfolded and compact storage when folded, with automatic adjustment to prevent damage during folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current foldable display devices use compensation design for connection components, then the flexible display screen is protected from damage during bending, but the structural design becomes complicated and occupies large space
Solution Approach 1:
The patent uses a flexible display screen that can bend and fold without requiring complex rigid connection components. The flexible nature of the display screen itself provides the necessary compliance during bending, eliminating the need for elaborate compensation mechanisms while maintaining protection against damage.
2Reliability
If current foldable display devices use compensation design for connection components, then the flexible display screen is protected from damage during bending, but production costs increase and production efficiency decreases
Solution Approach 1:
By relying on the inherent flexibility of the display screen rather than complex connection components, the manufacturing process is simplified. This reduces production steps, lowers costs, and improves efficiency while still ensuring the screen remains protected during folding operations.
3Area of moving object
If foldable flexible display screen is combined with stretchable screen, then display area is enlarged and portability is improved, but structural complexity increases
Solution Approach 1:
The patent combines foldable and stretchable screen technologies into a single integrated flexible display system. This merging approach achieves larger display area and improved portability without proportionally increasing structural complexity, as the two functions are unified in one continuous flexible structure rather than requiring separate mechanisms.
