Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional static display screens are installed in the instrument panel, then the display device structure is simple and easy to manufacture, but the display effect is poor due to varying display conditions and external light interference
Solution Approach 1:
The display screen is transformed from a static fixed installation to a dynamic foldable structure that can rotate and adjust its orientation. The screen includes a folded portion and multiple unfolded portions that can be rotated relative to each other, allowing the display surface to dynamically adapt to different viewing angles and lighting conditions, thereby improving display effect while maintaining manufacturing feasibility
Solution Approach 2:
The display device changes its physical parameters (orientation angle, surface area orientation) through rotation mechanisms. By adjusting the rotation angle of unfolded portions relative to the folded portion, the display screen can optimize its orientation to reduce external light interference and improve visibility under varying driving conditions
2Device complexity
If traditional fixed display screens are used, then the device structure is simple, but the display device is not suitable for a plurality of driving modes
Solution Approach 1:
The foldable display structure enables dynamic reconfiguration of the screen orientation and angle through rotation mechanisms, allowing the display to adapt to different driving modes (e.g., normal driving, parking, charging) without requiring multiple separate display devices, thus improving versatility while controlling structural complexity
Solution Approach 2:
The display device is designed to serve multiple functions across different driving scenarios. The same foldable display structure can be adjusted to provide optimal viewing angles for driver information display, passenger entertainment, charging interface display, and other modes, making a single device suitable for multiple driving modes

Function Achieved in This Case
The foldable design enhances display quality by using OLED screens and effectively blocks external light, improving the display experience across various driving modes.
Implementation Method 1
the second unfolded portion rotates around the rotating component within a rotation range from 0° to 180°
Implementation Method 2
a light-blocking component is disposed on edges of both sides of the display device perpendicular to the rotating component respectively... the light-blocking component unfolds as the display device unfolds, or folds as the display device folds
