A flexible display integrated into a blade assembly that slides around a single device housing, transitioning between extended, retracted, and peek positions in response to user swipe gestures, with automatic state changes based on sensor inputs and artificial intelligence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a translating flexible display is implemented to provide a larger display surface area, then the display area is increased, but the device complexity increases due to the translation mechanism
Solution Approach 1:
The flexible display is nested within the device housing, allowing it to be stored compactly when not in use and deployed when needed. The display can be translated between retracted and extended positions, effectively providing a larger display surface area while maintaining a compact form factor when closed.
Solution Approach 2:
The display transitions from a static to a dynamic configuration, allowing it to change position between retracted and extended states. This dynamic capability enables the display to adapt its surface area based on user needs while maintaining a compact form factor when closed.
2Device complexity
If manual button presses are required for transitions between display states, then the device complexity is reduced, but the ease of operation deteriorates due to cumbersome manual transitions
Solution Approach 1:
The mechanical button-pressing system is replaced with a sensor-based detection system. Sensors detect user gestures or contextual conditions, and the display automatically transitions between states based on these detections, eliminating the need for manual button presses and improving ease of operation.
Solution Approach 2:
The display system performs self-service by automatically detecting user intent through sensors and autonomously transitioning between display states without requiring manual intervention. This self-service capability improves ease of operation while maintaining reasonable device complexity.
3Ease of operation
If automatic state changes based on sensor inputs are implemented, then the ease of operation is improved, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The manual mechanical control system is substituted with an automated sensor-based control system. Sensors detect user gestures or environmental conditions, and the control system automatically adjusts the display state, improving ease of operation despite the added complexity of sensors and control logic.
4Adaptability or versatility
If the display transitions between extended and retracted positions, then the adaptability is improved, but the loss of time increases due to transition duration
Solution Approach 1:
The display employs dynamic translation mechanisms that enable rapid transitions between extended and retracted positions. The dynamic design allows the display to quickly adapt to different usage scenarios, minimizing transition time while maintaining high adaptability.

AI summary
A method in an electronic device includes detecting, with a flexible display carried by a blade assembly that is slidably coupled to a device housing and movable between at least an extended position and a retracted position, user input defining a swipe gesture. The method then includes translating, by a translation mechanism operable with the blade assembly, the blade assembly toward the extended position in response to the swipe gesture.
