Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a folding display device uses a simple support structure for the folding area, then the device complexity is reduced, but the structural stability during folding and unfolding deteriorates
Solution Approach 1:
The support structure is divided into multiple support plates arranged in sequence along the folding axis direction. Each support plate is independently configurable with specific length and width dimensions, allowing the structure to be segmented into functional units that can be optimized individually while maintaining overall structural stability during folding operations.
Solution Approach 2:
The support plates are configured with varying lengths and widths based on their positions in the folding area. The length of each support plate in the folding axis direction increases from both ends toward the center, while the width increases from the center toward both ends. This dynamic configuration allows the structure to adapt to the curvature changes during folding and unfolding, maintaining stability without requiring excessive complexity.
2Manufacturing precision
If the support plates have uniform dimensions, then the manufacturing precision is improved, but the adaptability to varying curvatures deteriorates
Solution Approach 1:
Each support plate is assigned different dimensional characteristics based on its local position within the folding area. The length and width of support plates vary according to their specific location, with the length increasing from ends toward center and width increasing from center toward ends. This local quality approach ensures that each plate is optimally sized for its specific role in accommodating curvature variations.
Solution Approach 2:
The patent systematically changes the dimensional parameters (length and width) of support plates based on their positions. By adjusting these parameters according to location-specific requirements, the structure achieves high adaptability to varying curvatures during folding operations while maintaining precise manufacturing specifications for each individual plate.
3Volume of moving object
If the folding area has high curvature, then the compactness during folded state is improved, but the mechanical stress on components increases
Solution Approach 1:
The support plates are dynamically configured with varying dimensions to match the curvature profile of the folding area. The length increases from ends toward center while width increases from center toward ends, creating a gradient structure that distributes mechanical stress more evenly across the folding area during high-curvature folding states, reducing peak stress on individual components.
Solution Approach 2:
By changing the dimensional parameters of support plates according to their positions, the structure optimizes the distribution of mechanical stress during folding. The parameter variations allow the support structure to better accommodate high curvature while maintaining compactness, as each plate's dimensions are tailored to its specific stress conditions.

AI summary
A display device includes a display module including a folding area that is configured to fold with respect to a folding axis that is substantially parallel to a first direction and first and second non-folding areas arranged in a second direction crossing the first direction with the folding area interposed therebetween. A first body is disposed under the first non-folding area. A second body is disposed under the second non-folding area. A center body is disposed under the folding area. A plurality of support plates extending in the first direction, arranged in the second direction, are disposed between the center body and the folding area and are rotatably coupled with each other. Lengths in the second direction of the support plates increase as a curvature of the folding area decreases.
