Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional flexible screen devices lack reliable support mechanisms, limiting their operability and practicality as they cannot fully utilize the characteristic of flexible deformation.
Innovation Solution
A system for controlling deformation of a flexible screen, comprising a flexible screen body with a metal layer and a current-controlled deformation layer made of electrorheological fluid or metal-water complex, regulated by a hardness regulation circuit that adjusts current flow to soften or harden the layer, allowing the screen to form desired shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible screen is made attachable on a support with a given shape, then the screen has reliable support and improved stability, but the flexible deformation capability is limited and the screen can only display on a curved surface
Solution Approach 1:
The patent applies a current-controlled deformation layer that can dynamically change its properties based on applied current. The layer transitions between soft and hard states, allowing the screen to adapt its shape and support characteristics in real-time rather than being fixed to a predetermined curved surface.
Solution Approach 2:
The patent changes the physical parameter of the deformation layer by controlling its hardness through current application. The layer's hardness parameter can be adjusted between soft and hard states, enabling the screen to achieve both flexible deformation and stable support configurations as needed.
2Adaptability or versatility
If the flexible screen is made completely flexible without support, then the flexible deformation capability is maximized, but the operability and practicability deteriorate due to lack of reliable support
Solution Approach 1:
The system dynamically adjusts the support characteristics by controlling the deformation layer's hardness through current. When operability is needed, the layer softens to allow flexible manipulation; when stability is needed, the layer hardens to provide reliable support.
Solution Approach 2:
The deformation layer serves dual functions: it provides flexible deformation when needed and self-generates support stability when required, eliminating the need for separate rigid support structures.
3Ease of operation
If a rigid support structure is used to provide stable support, then the operability is improved, but the flexible deformation capability is reduced and the screen cannot change shape freely
Solution Approach 1:
The patent uses a deformation layer whose hardness parameter can be changed through current control. The layer transitions from soft to hard state to provide support only when needed, allowing the screen to maintain full shape change capability while obtaining operability support on demand.
