Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to freely change the curvature of the display panel and require structures that can accommodate bending or flattening while minimizing thickness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid frame structure is used to support the display panel, then structural stability is improved, but the ability to change curvature is lost
Solution Approach 1:
The frame structure is designed with dynamic characteristics, allowing it to transition between flat and bent states. The frame includes flexible portions that can elastically deform to accommodate curvature changes of the display panel while maintaining structural integrity during transitions.
Solution Approach 2:
The frame incorporates flexible portions with specific structural characteristics that enable elastic deformation. These flexible portions act as thin film structures that can bend and return to original shape, allowing the rigid frame to adapt to panel curvature changes without compromising overall stability.
2Adaptability or versatility
If a flexible structure is used to allow curvature change, then adaptability is improved, but structural stability deteriorates
Solution Approach 1:
The frame is divided into multiple portions: rigid portions that provide structural stability and flexible portions that enable curvature adaptation. This segmentation allows different parts of the frame to perform different functions - rigid sections maintain stability while flexible sections accommodate shape changes.
Solution Approach 2:
Different portions of the frame have different structural qualities - some areas are designed to be rigid for stability, while specific flexible portions are designed to be deformable for curvature adaptation. This local differentiation of properties allows the frame to simultaneously achieve both stability and adaptability.
3Stability of the object's composition
If thick structural components are used to maintain stability during bending, then structural stability is improved, but device thickness increases
Solution Approach 1:
The frame uses thin flexible portions with optimized structural characteristics that can maintain stability during bending without requiring increased thickness. These thin film structures rely on elastic deformation rather than mass for their stability during curvature changes.
Solution Approach 2:
The frame incorporates composite structural characteristics combining rigid and flexible materials or structures in specific configurations. This composite approach allows thin sections to achieve both flexibility for bending and sufficient stability through material property optimization rather than thickness increase.
