Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices lack the ability to freely change curvature without risking damage to the display panel, limiting their adaptability and usability in various applications.
Innovation Solution
A display device with an open frame structure and a drive mechanism that allows for the flexible change of curvature by using a side frame and drive unit to apply attraction or repulsion forces, adjusting the gap between the flexible display panel and rigid bar, and incorporating a hinge-coupled wing plate to alter the curvature of the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used to enable curvature changes, then adaptability is improved, but the display panel may be damaged during curvature adjustment
Solution Approach 1:
A support frame is introduced as an intermediary structure between the drive mechanism and the flexible display panel. The support frame provides a stable structural basis that guides and supports the curvature adjustment process, preventing direct stress concentration on the display panel that could cause damage while enabling the desired curvature changes.
Solution Approach 2:
The support frame acts as a protective structure that anticipates and prevents potential damage to the flexible display panel during curvature adjustment. By providing structural support and guidance before the curvature change occurs, the system prevents stress concentration and potential panel failure.
2Ease of operation
If mechanical actuators are used to change display curvature, then curvature control is achieved, but the device structure becomes complex
Solution Approach 1:
The support frame is designed with movable connections that allow dynamic adjustment of the flexible display panel's curvature. The frame structure itself is configured to enable bending movements, transforming the static support structure into a dynamic system that adapts to curvature changes without requiring complex external actuators.
Solution Approach 2:
The support frame serves multiple functions simultaneously: it provides structural support, guides the curvature adjustment, protects the display panel, and enables the bending movement. This multi-functionality reduces the need for separate mechanical actuators and other auxiliary components, simplifying the overall device structure.
3Adaptability or versatility
If the gap between flexible display panel and rigid bar is reduced to increase curvature range, then curvature adaptability is improved, but the risk of display panel damage increases
Solution Approach 1:
The support frame serves as an intermediary that enables the flexible display panel to approach closer to the rigid bar while preventing direct contact and potential damage. The frame structure distributes and manages the stress that arises during curvature adjustment, allowing for a reduced gap and increased curvature range without compromising panel integrity.
