Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of sensors (touch sensors, bending sensors) are configured on the flexible display to provide different operation modes, then the user interaction becomes more intuitive and versatile, but the cost and device complexity increase
Solution Approach 1:
The patent applies universality by enabling pressure sensors to perform multiple functions that previously required different sensor types. The pressure sensors detect both touch operations (clicking, pressing) and bending operations by analyzing pressure values, pressure areas, and pressure variances, allowing a single sensor type to replace multiple specialized sensors while maintaining versatile display mode support
Solution Approach 2:
The patent applies parameter changes by utilizing different parameters from the same sensor type (pressure sensors) to detect different operations. By analyzing variations in pressure values, pressure areas, and pressure variances, the system distinguishes between touch operations and bending operations using a single sensor type, thereby reducing device complexity while maintaining adaptability
2Ease of operation
If multiple types of sensors are configured on the flexible display to detect different operations, then the user interaction becomes more intuitive, but the cost of the flexible display increases
Solution Approach 1:
The patent reduces manufacturing cost by applying universality, where pressure sensors serve multiple detection purposes. Instead of manufacturing and assembling multiple specialized sensors (touch sensors, bending sensors), the system uses a single type of pressure sensor to detect both touch and bending operations, simplifying the manufacturing process and reducing component costs while maintaining intuitive user interaction
3Device complexity
If fewer types of sensors are used to reduce cost and complexity, then the manufacturing becomes simpler and cost decreases, but the ability to provide different operation modes may be limited
Solution Approach 1:
The patent resolves this contradiction by applying parameter changes, where the system extracts multiple operation types from a single sensor type by analyzing different parameters. The pressure sensors generate pressure values, and the system analyzes pressure areas and pressure variances to distinguish between different operations (touch vs. bending), thereby maintaining adaptability while reducing device complexity
Solution Approach 2:
The patent applies segmentation by dividing the detection process into distinct analysis stages. The system segments the pressure sensor data into different operational categories (touch operations, bending operations) based on pressure area and pressure variance thresholds, allowing a single sensor type to provide multiple display modes through systematic data analysis

AI summary
A flexible display and a controlling method thereof are provided. The flexible display includes a plurality of pressure sensors, a display unit and a processing unit, wherein the processing unit is connected to the pressure sensors and the display unit. The processing unit obtains pressure values from each of the pressure sensors within a time unit and generates a pressure area and a pressure variance according to the pressure values from each of the pressure sensors. The processing unit further determines a display mode of the display unit according to the pressure area and the pressure variance. Therefore, the flexible display is capable of providing several kinds of display mode only based on the equipped pressure sensors.
