Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed rigid frame structure is used, then structural stability is maintained, but the ability to change display panel curvature is lost
Solution Approach 1:
The patent applies the dynamics principle by transforming the static rigid frame into a dynamic mechanism with movable arms and joints. The frame now includes arms that can pivot and extend, allowing the display panel curvature to be adjusted dynamically while maintaining structural integrity through controlled mechanical motion
Solution Approach 2:
The frame is segmented into multiple independent arms and joints rather than a single rigid structure. This segmentation allows each arm to move independently to achieve different curvature configurations, enabling both adaptability and stability through modular mechanical components
2Adaptability or versatility
If the display panel is made flexible to enable curvature change, then adaptability improves, but manufacturing precision and structural integrity may be compromised
Solution Approach 1:
The patent introduces mechanical arms and joints as intermediary components between the control system and the flexible display panel. These intermediaries provide precise mechanical control over the panel's curvature, ensuring manufacturing precision is maintained even as the panel becomes more flexible and adaptable
3Adaptability or versatility
If a complex mechanism is added to enable curvature change, then adaptability increases, but device complexity increases
Solution Approach 1:
The patent employs flexible mechanical arms and thin-film structural components that can bend and pivot to achieve curvature adjustment. This approach enables adaptability through flexible structures rather than complex rigid mechanisms, reducing overall device complexity while maintaining the ability to change display panel curvature
