Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices with increasing screen sizes face issues of size and portability, as they tend to crumple and get damaged when bent due to their bending properties.
Innovation Solution
A middle frame comprising a first and second framework component, chain link elements, a flexible element, and rotors that allow for rotary and slideable connections, distributing stress and compensating for shape changes to enhance bending properties and reduce damage.

Engineering Contradiction Analysis
1Area of moving object
If flexible display devices are made with large screen sizes, then the display area is improved, but the device becomes more prone to crumpling and damage when bent
Solution Approach 1:
The middle frame is divided into multiple chain link elements (first chain link element, second chain link element, third chain link element, fourth chain link element) that are connected through rotors. This segmentation allows the frame to flex and distribute stress across multiple segments rather than concentrating force on a single point, thereby preventing crumpling while maintaining large display area.
Solution Approach 2:
The chain link elements are configured to be movable relative to each other through rotors, enabling the middle frame to dynamically adapt its shape during bending. The rotors allow controlled rotation and movement of chain links, transforming the rigid structure into a flexible yet durable configuration that resists damage while accommodating large screen sizes.
2Ease of operation
If flexible display devices are made bendable, then portability is improved, but the device structure becomes more complex
Solution Approach 1:
The rotors serve multiple functions: they connect chain link elements, enable relative movement between links, provide rotational joints for flexibility, and distribute mechanical stress. This multi-functionality reduces the need for additional specialized components, maintaining structural efficiency while achieving bendability for improved portability.
Solution Approach 2:
The middle frame employs a chain link structure with rotors that creates a flexible yet robust framework. This flexible structure allows the display device to be bent without damage, enhancing portability while the modular chain link design keeps the overall structural complexity manageable through repeated use of standardized components.
