Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid displays are used in portable terminals, then structural stability is maintained, but spatial arrangement flexibility and functionality are limited
Solution Approach 1:
The patent employs flexible display panels that can be bent, folded, or rolled without compromising structural integrity. The display device includes flexible sensors, touch sensors, and pressure sensors integrated into the flexible structure, enabling the device to maintain functionality while adapting to various spatial configurations and user interactions.
2Adaptability or versatility
If flexible display technology is implemented, then spatial arrangement flexibility is enhanced, but device complexity increases due to multiple sensors and processing requirements
Solution Approach 1:
The flexible display device integrates multiple sensor types (flexible sensors, touch sensors, pressure sensors) that can detect various input events (bends, touches, pressures). These sensors share a common processing architecture that determines event types and executes corresponding operations, allowing one system to perform multiple functions including display flexibility, touch detection, and pressure sensing.
Solution Approach 2:
The patent combines multiple sensing capabilities into a unified flexible display structure. The flexible sensor, touch sensor, and pressure sensor are integrated layers within the same display panel, sharing common support structures and processing circuits, thereby reducing overall device complexity compared to separate systems.
3Ease of operation
If simple signal input is used, then device operation is straightforward, but interaction capability and data display versatility are limited
Solution Approach 1:
The flexible display device dynamically adapts its interaction modes based on the type of input detected. The processor determines whether the input is a bend event, touch event, or pressure event, and automatically executes the appropriate operation from a list of predefined operations. This dynamic response system maintains ease of operation while significantly enhancing interaction capability and data display versatility.
