Rotatable Vehicle Display Screen Adapting to Driving Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display screens in autonomous vehicles are not suitable for viewing both vehicle functions in manual driving mode and multimedia content in autonomous driving mode due to limited space and differing display formats, necessitating an improved solution that adapts to different orientations and usage scenarios.
Innovation Solution
A multi-mode screen device with a display screen unit that automatically switches between portrait and landscape orientations based on driving modes, utilizing a translation unit with an inner and outer hollow shaft and guiding protrusions, and an electric motor for efficient rotation and axial displacement, allowing full screen area utilization and providing haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed orientation display screen is used, then the display format is simple and device complexity is low, but the display screen cannot adapt to different driving modes and loses versatility
Solution Approach 1:
The display screen unit is made rotatable and can dynamically change its orientation between portrait and landscape modes based on the driving mode. The screen is coupled with a rotating mechanism that allows it to pivot between different angular positions, transforming a static display into a dynamic one that adapts to operational requirements.
Solution Approach 2:
The display screen is designed to serve multiple functions by adopting different orientations. In portrait mode, it displays vehicle function information for manual driving; in landscape mode, it presents multimedia content for autonomous driving. This single screen structure thus performs multiple roles that would traditionally require separate display devices.
2Reliability
If the display screen orientation is manually changed, then device complexity is low, but driver distraction increases and safety decreases
Solution Approach 1:
The system incorporates feedback from the driving mode detection mechanism to automatically control the display orientation. When the vehicle transitions between manual and autonomous driving modes, the system receives this feedback signal and automatically rotates the display screen to the appropriate orientation, eliminating the need for manual intervention.
Solution Approach 2:
The display screen system serves itself by automatically adjusting its orientation based on the vehicle's operational state. The rotating mechanism is integrated with the vehicle's control system, allowing the display to self-adjust without requiring driver action, thus maintaining safety while providing appropriate display formats.
3Productivity
If a single display orientation is used, then device complexity is low, but screen area utilization is inefficient and productivity is reduced
Solution Approach 1:
The display screen unit is made rotatable and can dynamically change its orientation between portrait and landscape modes based on the driving mode. The screen is coupled with a rotating mechanism that allows it to pivot between different angular positions, transforming a static display into a dynamic one that adapts to operational requirements.
Solution Approach 2:
The solution introduces rotational freedom to the display screen, adding a dimensional aspect to its configuration. Instead of being fixed in one orientation, the screen can rotate around an axis, utilizing the available space more effectively and providing optimal viewing angles for different content types and driving scenarios.
