Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display size is changed to maintain portability and provide larger screen when needed, then the display versatility and portability are improved, but the measurement precision of the display area is worsened due to sensor measurement errors
Solution Approach 1:
The system continuously monitors the flexible display position using sensor modules and implements feedback control by comparing measured positions with expected positions. When deviations are detected, the system generates correction values to adjust the display area, ensuring accurate content presentation despite display size changes.
Solution Approach 2:
The system dynamically changes display parameters including display area size, resolution, and refresh rate based on the actual flexible display position and expansion state. This allows the display to adapt to different sizes while maintaining measurement precision through real-time parameter adjustment.
2Ease of operation
If the flexible display expands and contracts frequently to adapt to user needs, then the ease of operation is improved, but the reliability of content display is worsened due to accumulated measurement errors
Solution Approach 1:
The system performs preliminary calibration of sensor modules and establishes reference positions before normal operation. Correction values are pre-calculated based on expected display configurations, allowing the system to quickly compensate for measurement errors during frequent expansion and contraction operations.
Solution Approach 2:
The system implements continuous feedback monitoring of display position and content alignment. When measurement errors are detected during frequent operations, the system automatically generates and applies correction values to maintain content display reliability throughout the operation cycle.
3Adaptability or versatility
If sensor modules are used to track flexible display position for dynamic sizing, then the adaptability is improved, but the device complexity is worsened due to additional sensors and correction mechanisms
Solution Approach 1:
The sensor modules are designed to serve multiple functions: tracking flexible display position, determining expansion state, and providing data for both user interface updates and content rendering corrections. This multi-functionality reduces the need for separate specialized sensors and simplifies the overall system architecture.
Solution Approach 2:
The system merges the position tracking and content alignment correction functions into a unified processing framework. The processor integrates sensor data, calculates display area adjustments, and coordinates content rendering corrections in a single coordinated system, reducing complexity compared to separate independent subsystems.

AI summary
According to certain embodiments, an electronic device, comprises a sensor module; a flexible display; and a processor operatively connected to the sensor module and the flexible display, wherein the processor is configured to: measure a first position of the flexible display using the sensor module, thereby resulting in a measured first position value, measure a second position of the flexible display using the sensor module based on a movement of the flexible display, thereby resulting in a measured second position value, determine a change amount in movement of the flexible display using the measured first position value and a measured second position value, thereby resulting in a determined movement change, correct the measured second position value using a threshold based on the determined movement change amount of the flexible display, thereby resulting in a corrected second position value, and display a screen based on the corrected second position value.
