Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is made bendable to enable curvature change between flat and curved modes, then the adaptability and user experience are improved, but the reliability and stability are worsened due to noise and abrasion from repeated bending
Solution Approach 1:
The display device is divided into multiple parts connected by hinge components, allowing the display module to be segmented into sections that can independently bend and rotate. This segmentation enables curvature change while distributing mechanical stress, thereby maintaining reliability during repeated bending operations.
Solution Approach 2:
The hinge component includes torque adjustment mechanisms that allow dynamic adjustment of torque parameters to maintain the display module in different states (flat, curved, or intermediary). By adjusting the torque parameter, the system can adapt to different curvature requirements while maintaining stability and preventing excessive wear through controlled mechanical resistance.
2Ease of operation
If the hinge component allows repeated bending between flat and curved states, then the ease of operation is improved, but the durability is worsened due to wear and tear from continuous movement
Solution Approach 1:
The hinge component incorporates stoppers that engage with the display module at specific positions (flat state, curved state, and intermediary states). These stoppers provide beforehand cushioning by limiting the range of motion and preventing excessive bending, thereby reducing wear on the hinge components and extending device longevity while maintaining ease of operation.
Solution Approach 2:
The torque adjustment mechanisms provide feedback control by allowing the user to adjust the torque based on the desired curvature state. This feedback mechanism enables precise control over the bending force, preventing over-bending and reducing mechanical wear while maintaining operational ease.
3Reliability
If stoppers are added to maintain the display module in specific states, then the stability is improved, but the device complexity increases
Solution Approach 1:
The stoppers are integrated into the hinge component structure, merging the state-maintenance function with the existing hinge mechanism. This integration allows the stoppers to work in conjunction with the torque adjustment mechanisms, providing state maintenance (flat, curved, or intermediary) without requiring separate complex systems, thereby limiting the increase in device complexity.
