Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible display devices use simple signal input for data display, then device complexity is reduced, but adaptability to various input systems and display modes is limited
Solution Approach 1:
The patent implements a function table that maps multiple input types (touch events, bend events, gesture events) to multiple display modes (page turning, enlargement/reduction, scrolling). This universal mapping structure allows the device to handle various input systems through a unified interface, achieving multi-functionality without proportionally increasing device complexity. The controller references the function table to determine appropriate display responses based on input type and location.
Solution Approach 2:
The patent changes the parameters of input detection by introducing multiple sensor types (touch sensor for touch events, flexible sensor for bend events) and varying detection parameters such as touch location, bend angle, and gesture patterns. These parameter changes enable the device to distinguish between different input types and trigger corresponding display modes, enhancing adaptability while maintaining manageable complexity through systematic parameter management.
2Ease of operation
If flexible display devices implement multiple display modes, then adaptability and usability are enhanced, but device complexity increases
Solution Approach 1:
The function table operates as a self-service mechanism where the controller automatically references the table to determine the appropriate display mode based on detected input events. This automated lookup process eliminates the need for complex decision-making algorithms or user configuration, allowing multiple display modes to be implemented while keeping the control logic simple and maintenance-free.
Solution Approach 2:
The function table is pre-configured with mappings between input types and display modes before device operation. This preliminary action of establishing the mapping relationships in advance allows the device to quickly respond to user inputs without real-time complex processing, enhancing usability while minimizing runtime complexity.
3Adaptability or versatility
If flexible display devices use touch sensor and flexible sensor for input detection, then input capability is enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the touch sensor and flexible sensor into a unified input detection system where both sensors work together to provide complementary information. The touch sensor detects touch events on the display surface, while the flexible sensor detects bend events that indicate gesture input. By combining these sensors and processing their outputs through a unified function table, the system achieves enhanced input capability while managing manufacturing complexity through integration rather than separate processing systems.
