Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible OLED screens with special shapes and sizes are customized for automotive displays, then the display can match various automotive interior radians and improve appearance, but the mold opening costs increase to 30-50 million yuan
Solution Approach 1:
The patent uses a universal rectangular OLED panel that can be folded into various shapes and sizes to create different display configurations. Instead of customizing molds for each display shape, a single rectangular panel design serves multiple automotive interior applications through folding, achieving versatility without proportionate cost increase
Solution Approach 2:
The rectangular OLED panel is divided into folding regions that can be bent at specific locations to create different display shapes. This segmentation allows the same panel to be configured for various automotive interior radians and display orientations without requiring separate custom molds for each configuration
2Reliability
If flexible OLED screens are customized for automotive displays, then the display effects are improved, but the manufacturing yield decreases due to low usage volume
Solution Approach 1:
A single rectangular OLED panel design serves multiple automotive display applications through folding configurations. This universal design enables mass production of standard rectangular panels with high yield, while post-manufacturing folding allows customization for different vehicle models and display requirements, maintaining quality without sacrificing productivity
Solution Approach 2:
The OLED panel is manufactured in a standard rectangular form with predetermined folding regions before being installed in the vehicle. This preliminary preparation allows high-volume production of standardized panels with consistent quality, while the folding step later adapts them to specific automotive applications without requiring low-yield custom manufacturing for each case
3Ease of manufacture
If a rectangular foldable OLED panel is used instead of customized flexible OLED screens, then the manufacturing cost decreases and yield increases, but the ability to match various automotive interior radians is reduced
Solution Approach 1:
The rectangular OLED panel incorporates folding regions that allow dynamic reconfiguration into various shapes and sizes. This dynamic folding capability enables a single standardized panel design to adapt to different automotive interior radians and display requirements, maintaining versatility while benefiting from the cost advantages of standardized manufacturing
Solution Approach 2:
The panel's effective display parameters (shape, size, orientation) are changed through folding rather than through custom manufacturing. By altering the physical configuration of a standard rectangular panel, the design achieves adaptability to various automotive interiors without requiring parameter-specific custom production, thus reducing manufacturing costs while maintaining versatility
