Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is separated by bending, then the flexible display apparatus can be used for various mobile apparatuses, but there is a lack of comprehensive control methods for utilizing shape deformation
Solution Approach 1:
The patent segments the bending detection into multiple sensing units positioned at different locations and orientations on the flexible display apparatus. Each sensing unit detects bending in specific directions, and the controller integrates these segmented detection results to determine overall shape deformation, resolving the contradiction by making the complex control method manageable through modular sensing
Solution Approach 2:
The patent creates a universal control method that can be applied to various flexible display apparatuses regardless of their specific configuration. The controller uses a standardized approach to detect shape deformation through multiple sensing units and applies predetermined operations based on the detected deformation, making the control method universally applicable while maintaining versatility
2Measurement precision
If multiple sensing units are arranged in different directions to detect shape deformation, then the detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by positioning sensing units at specific strategic locations on the flexible display apparatus rather than uniformly distributing them. Each sensing unit is placed where it can detect specific types of bending most effectively, optimizing detection accuracy while minimizing the total number of sensing units required
Solution Approach 2:
The patent adds dimensional complexity to the detection system by arranging sensing units in different spatial orientations and directions. This multi-dimensional arrangement allows the system to detect shape deformation from multiple angles simultaneously, improving measurement precision without requiring a proportional increase in the number of sensing units
3Ease of operation
If the flexible display apparatus responds to different bending types with different operations, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the flexible display apparatus to automatically interpret and respond to user bending gestures without requiring additional input mechanisms. The sensing units and controller work together to detect shape deformation and autonomously execute predetermined operations, making the device easier to operate while managing control complexity through automation
Solution Approach 2:
The patent uses parameter changes by varying the detection thresholds and response criteria for different types of bending deformations. The controller adjusts its operation based on the magnitude, direction, and duration of detected shape deformation, allowing intuitive user interaction while managing control complexity through parameter-based decision making

AI summary
A flexible display apparatus is provided. The flexible display apparatus includes a display, a sensor which senses shape deformation of the display, a storage which, if a shape deformation is sensed, stores operation state information of a first operation state of the flexible display apparatus prior to the first shape deformation being performed, and a controller which performs a function corresponding to the first shape deformation if a second shape deformation different from the first shape deformation is sensed, returns to the first operation state according to the operation state information stored in the storage.
