Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foldable display panel is designed with multiple regions and support bodies to enable various configurations, then the adaptability and versatility of the display is improved, but the device complexity increases due to additional components and structural elements
Solution Approach 1:
The display panel is divided into multiple regions (first region, second region, third region, fourth region) that can be independently folded and configured. The support structures are also segmented into first and second support bodies, each capable of independently supporting different regions. This segmentation enables the display to achieve various configurations (unfolded, folded, partially folded) without requiring a completely complex unified structure.
Solution Approach 2:
The support bodies are designed with universal functionality to support multiple regions in different configurations. The first support body can support either the first region alone or both the first and second regions when folded. Similarly, the second support body can support either the fourth region alone or both the third and fourth regions when folded. This multi-functionality reduces the need for dedicated support structures for each possible configuration.
2Ease of operation
If magnetic coupling portions are added to connect support bodies, then the ease of operation and configuration changes is improved, but the device complexity increases due to additional magnetic components
Solution Approach 1:
The patent replaces traditional mechanical coupling mechanisms (such as hinges, clips, or fasteners) with magnetic coupling portions. The first and second support bodies include magnetic coupling portions that automatically attract and connect when brought into proximity, enabling easy configuration changes without manual assembly or disassembly of mechanical parts. This substitution simplifies the user interaction while reducing the complexity of moving parts.
Solution Approach 2:
The magnetic coupling portions enable the support bodies to self-connect and self-align when brought into proximity. The magnetic attraction force automatically guides the coupling portions into proper alignment and maintains the connection, eliminating the need for precise manual positioning or additional locking mechanisms. This self-service capability improves ease of operation while minimizing additional components.
3Volume of moving object
If the display panel is folded to increase portability, then the volume and portability are improved, but the manufacturing precision requirements increase to ensure proper alignment and support
Solution Approach 1:
The support bodies act as intermediary elements between the folded regions of the display panel. When the display is folded, the support bodies maintain the relative positions and alignment of the folded regions, compensating for any dimensional tolerances or misalignments that may occur during manufacturing or assembly. This intermediary function reduces the stringency of manufacturing precision requirements while ensuring proper configuration.
Solution Approach 2:
The magnetic coupling portions utilize magnetic field strength as a controllable parameter to ensure proper connection and alignment. By adjusting the magnetic coupling force, the system can accommodate variations in manufacturing tolerances and ensure reliable connection across different folding configurations. This parameter-based approach allows for greater manufacturing flexibility while maintaining alignment precision.

AI summary
A foldable display is disclosed. In one aspect, the foldable display includes a foldable display panel including first to fourth regions adjacent to each other. The foldable display also includes a first support located on a rear surface of the first region and a second support located on a rear surface of the fourth region. The foldable display panel is configured to be arranged in a first configuration in which the foldable display panel is unfolded and a second configuration in which the foldable display panel is folded so that the first support supports the first and second regions and the second support supports the third and fourth regions.
