Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flexible display screen is kept in a fixed shape, then the structure is simple and easy to manufacture, but the visual experience deteriorates due to aesthetic fatigue
Solution Approach 1:
The display screen transitions from a static fixed shape to a dynamic configurable shape. The screen can be adjusted between flat and curved states, and can maintain different curved shapes according to the adsorption plate's configuration, enabling shape adaptability while maintaining manufacturing simplicity through the adsorption mechanism
Solution Approach 2:
The adsorption plate serves as an intermediary between the flexible display screen and the housing. It provides the curved surface that the screen adheres to, enabling shape changeability without requiring complex integrated structures. The adsorption plate can be independently configured and replaced, separating the shape-control function from the screen and housing
2Adaptability or versatility
If the flexible display screen is made changeable in shape, then the visual experience improves, but the device complexity increases due to additional components
Solution Approach 1:
The adsorption plate performs multiple functions: it provides structural support for the flexible display screen, defines the curved shape configuration, and enables shape transformation through its replaceable design. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in device complexity
Solution Approach 2:
The flexible display screen utilizes its own flexibility property to conform to the adsorption plate's curved surface through adsorption forces. The screen's inherent material characteristics are leveraged to achieve shape changeability without requiring additional active control mechanisms or complex actuation systems
3Area of stationary object
If the flexible display screen is unrolled and displayed, then the display area increases, but the screen becomes vulnerable to deformation and damage
Solution Approach 1:
The adsorption plate provides localized support and constraint to the flexible display screen at the curved surface interface. This localized adsorption force stabilizes the screen in its unrolled displayed state, preventing deformation and damage while maintaining the increased display area
