Solution Overview
Problem
Conventional support systems for flexible display panels using electrorheological fluids require maintaining high viscosity for fixation, which is inefficient and consumes excessive power.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrorheological fluid's viscosity is maintained at a high degree for fixation, then the flexible display panel can be firmly fixed, but the power consumption increases excessively
Solution Approach 1:
The support system is divided into multiple independent support regions, each with its own application electrodes. This allows selective activation of only the necessary support areas rather than maintaining high viscosity across the entire electrorheological fluid, thereby reducing power consumption while maintaining fixation stability where needed.
Solution Approach 2:
The electrorheological fluid's viscosity is made non-uniform by applying electric fields only to specific local regions through application electrodes. This creates high viscosity locally at support points while maintaining low viscosity in other areas, achieving effective fixation with minimal power consumption.
2Reliability
If the electrorheological fluid's viscosity is increased for fixation, then the supported target can be held firmly, but the flexibility and deformability of the system is reduced
Solution Approach 1:
The support system dynamically adjusts the viscosity of the electrorheological fluid by controlling the application electrodes. The system can switch between a deformable state (low viscosity) for installation and positioning, and a fixable state (high viscosity) for stable support, providing both flexibility and fixation strength as needed.
Solution Approach 2:
The application electrodes are controlled to apply electric fields periodically or intermittently rather than continuously. This allows the electrorheological fluid to alternate between high and low viscosity states, enabling the system to achieve both deformability during adjustment and firm fixation during operation.
