Flexible Display Panel Curvature Adjustment via Gear-Driven Frame Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies lack the ability to seamlessly transition between flat and curved modes, limiting user experience and immersion in visual content.
Innovation Solution
A display apparatus featuring a flexible display panel with adjustable frames and spacers, including a gear system, allows for easy conversion between flat and curved modes by altering the distance between frames, enabling the display panel to maintain a flat shape or curve based on user preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed rigid frame structure is used, then structural stability is improved, but the ability to change display curvature is lost
Solution Approach 1:
The frame structure is designed with adjustable components that allow it to transition between fixed and flexible states. The distance between first and second frames can be dynamically changed using a gear system, enabling the display to switch between flat and curved modes while maintaining structural integrity in each state.
Solution Approach 2:
The frame is divided into multiple segments (first frame, second frame, and additional frames) that can move independently relative to each other. This segmentation allows the structure to maintain stability when frames are fixed at specific distances while enabling curvature adjustment when frames are repositioned.
2Shape
If the distance between frames is increased, then the display can maintain a flat shape, but the immersion effect is reduced
Solution Approach 1:
The distance between frames is made dynamically adjustable rather than fixed. A gear system with racks and pinions enables smooth transition between larger distances (flat mode for viewing comfort) and smaller distances (curved mode for immersion), allowing the display to adapt its shape characteristics based on usage requirements.
3Adaptability or versatility
If a curved display mode is implemented, then immersion is improved, but the display panel stress increases
Solution Approach 1:
The display panel is designed as a flexible component that can bend to match the curved frame configuration. The flexible nature of the panel allows it to conform to the curved shape without excessive stress, while the frame structure provides support to distribute and manage the mechanical loads during curvature transitions.
Solution Approach 2:
The frame structure and spacer system are designed to control and limit the degree of curvature, preventing the display panel from bending beyond safe stress thresholds. The adjustable spacing between frames provides predetermined stopping points that cushion the panel from excessive mechanical stress while still achieving the desired curved display effect.
