Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foldable display is implemented to enable flexible form factors, then adaptability and versatility are improved, but the display may remain in unintended states (partially folded or unfolded) causing operational issues
Solution Approach 1:
The system continuously monitors the actual display state through sensors and compares it with the expected state. When a discrepancy is detected (e.g., display partially folded when fully folded is expected), the system generates feedback signals to trigger corrective actions, ensuring the display returns to the intended state and maintaining reliable operation.
Solution Approach 2:
The system determines the expected display state in advance based on the current operation mode before the user interacts with the device. By pre-establishing what the display state should be, the system can proactively detect and correct deviations, preventing operational issues before they occur.
2Device complexity
If the display state is not properly managed, then device complexity is reduced, but operational errors and user experience deteriorate
Solution Approach 1:
The system automatically monitors, determines, and corrects display state deviations without requiring user intervention. The electronic device self-manages the display state by detecting discrepancies between actual and expected states and autonomously triggering corrective actions, thereby maintaining operational accuracy while minimizing added complexity.
3Reliability
If corrective actions are automatically triggered, then reliability is improved, but device complexity and power consumption increase
Solution Approach 1:
The system replaces complex mechanical state detection and correction mechanisms with electronic sensing and software-based state determination. By using sensors to detect display state and software algorithms to determine expected states and trigger corrections, the system achieves high reliability while keeping the physical hardware relatively simple.
