Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid display panel is used, then the display structure is simple and stable, but the device consumes significant space and is inconvenient to use
Solution Approach 1:
The display panel is divided into a first non-folding area, a second non-folding area, and a first folding area between them. This segmentation allows different portions of the display to have different functional characteristics, with the folding area enabling compactness while non-folding areas maintain display functionality.
Solution Approach 2:
The display panel transitions from a static rigid structure to a dynamic flexible structure that can change between folded and unfolded states. The electromagnetic regions and magnetic regions enable controlled dynamic positioning, allowing the display to adapt its shape and size based on operational requirements.
2Adaptability or versatility
If a flexible display panel with electromagnetic regions is used, then the device can be folded and compacted, but the device complexity increases
Solution Approach 1:
The electromagnetic regions and magnetic regions are integrated directly into the flexible display panel structure. The retainer component combines multiple electromagnetic regions and magnetic regions in a single assembly that works together to maintain folded states, reducing the need for separate mechanical locking mechanisms.
Solution Approach 2:
Traditional mechanical folding mechanisms (hinges, locks, springs) are replaced with an electromagnetic field-based system. The electromagnetic force generated between electromagnetic regions and magnetic regions provides the holding force for folded states, eliminating complex mechanical components and reducing overall device complexity.
3Area of moving object
If electromagnetic regions are placed in non-display areas, then the display area is maximized, but the manufacturing precision requirements increase
Solution Approach 1:
The electromagnetic regions and magnetic regions are strategically positioned in specific non-display areas with predetermined geometric patterns. This local placement optimizes the electromagnetic force distribution while maintaining maximum display area, and the fixed patterns simplify manufacturing alignment requirements compared to distributed positioning.

AI summary
A foldable display device includes a flexible display panel and a retainer. The flexible display panel includes a first non-folding area, a second non-folding area, and a first folding area between the first and second non-folding areas. The retainer includes at least one first electromagnetic region in the second non-folding area and at least one first magnetic region in the first non-folding area. The first and second non-folding areas face each other when the flexible display panel is in a first folded state in the first folding area. The first folded state is maintained by an electromagnetic force generated between the at least one first electromagnetic region and the at least one first magnetic region.
