Segmented Display Frame for Variable Curvature and Edge Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to freely change the curvature of their display panels, limiting their flexibility and adaptability to different viewing angles and applications.
Innovation Solution
A display device design that includes a flexible display panel, a flexible inner plate coupled to the display panel, a frame covering the edge of the inner plate, and a drive module to power the bending or flattening of the inner plate and display panel. The frame features a top cover fixed to the inner plate and a side cover fixed to the display panel, with a gap between them that increases as the display panel is bent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made flexible to enable curvature change, then adaptability and flexibility are improved, but structural stability and reliability deteriorate
Solution Approach 1:
The frame is divided into multiple separate cover portions (first cover portion, second cover portion, third cover portion, fourth cover portion) that can move independently relative to each other. This segmentation allows each portion to adapt to curvature changes while maintaining overall structural integrity, resolving the contradiction between flexibility and stability.
Solution Approach 2:
The frame transitions from a static rigid structure to a dynamic structure where cover portions can move relative to each other during curvature changes. The gaps between cover portions increase or decrease dynamically based on the bending state, enabling the frame to adapt while maintaining reliability.
2Reliability
If the frame is made rigid to maintain structural integrity, then reliability is improved, but flexibility and adaptability to curvature changes deteriorate
Solution Approach 1:
The frame is segmented into multiple cover portions with gaps between them, allowing the structure to maintain integrity through controlled separation rather than rigid connection. This enables curvature adaptation while preserving structural reliability.
Solution Approach 2:
The frame incorporates flexible characteristics through gaps between cover portions that allow bending and deformation. This enables the rigid-looking frame to adapt to curvature changes while maintaining its structural integrity.
3Adaptability or versatility
If the gap between frame covers increases during bending, then flexibility and curvature adaptation are improved, but exposure of internal structures and aesthetic appearance deteriorate
Solution Approach 1:
A filler component is introduced as an intermediary element to fill the gaps between frame cover portions during bending. This mediator prevents internal structure exposure and maintains aesthetic appearance while allowing the necessary curvature adaptation.
Solution Approach 2:
The gap that initially appears as a harmful defect (exposing internal structures) is converted into a beneficial feature by introducing filler components. The filler components can be elastically deformed or displaced to fill gaps dynamically, turning the potential harm into a solution that maintains both flexibility and appearance.
