Rotatable Vehicle Display Layout for Overlapping Screen Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle display devices lack the flexibility to efficiently present a variety of information to drivers and passengers, particularly in autonomous vehicles where multiple types of data need to be displayed safely and space-efficiently.
Innovation Solution
A display device for vehicles featuring a housing with a first fixed display and a second rotatable display that overlaps the first display, driven by a module within the housing, allowing for adjustable display modes and expanded information presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple fixed displays are installed to provide comprehensive information, then information completeness is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent implements a rotatable display module that can dynamically change its orientation and position. The display module is coupled with a rotating mechanism allowing it to switch between different viewing angles and overlap with other displays, enabling one physical display to serve multiple informational purposes that would traditionally require multiple fixed displays.
Solution Approach 2:
The rotatable display module is designed to perform multiple functions: it can display information independently, overlap with the first display to expand the display area, and adjust its position based on different usage scenarios. This multi-functionality reduces the need for separate dedicated displays for different information types.
2Loss of information
If display area is expanded to show more information, then information presentation capability is improved, but space occupation and structural complexity increase
Solution Approach 1:
The patent introduces rotational movement as an additional dimension to the display system. Instead of only expanding the display area horizontally or vertically, the second display module can rotate to create overlapping display regions, effectively utilizing the third dimension (rotation angle) to expand the functional display area without proportionally increasing the physical footprint.
Solution Approach 2:
The rotatable display module can be positioned to overlap with the first display, creating a nested or layered display configuration. When rotated to certain positions, the second display partially overlaps the first display, allowing both displays to be visible simultaneously in a compact arrangement, effectively nesting one display within the visual space of the other.
3Reliability
If fixed display configuration is used for safety, then reliability is improved, but adaptability to different information needs deteriorates
Solution Approach 1:
The patent replaces the static fixed display configuration with a dynamic rotatable display system. The rotating mechanism allows the display module to adapt its position and orientation based on different information presentation needs while maintaining reliable connection and power supply through the rotating coupling.
Solution Approach 2:
The system allows changing the rotational angle parameter of the second display module to adapt to different information presentation requirements. By adjusting this single parameter (rotation angle), the display system can transform between different configurations to suit various information display needs while maintaining structural reliability.

AI summary
Disclosed is a display device for a vehicle. The display device for a vehicle comprises: a housing which is elongated and provides a receiving space therein; a first display fixed to the outside of the housing; a second display adjacent to the first display outside the housing and rotatably coupled to the housing; and a driving module installed in the receiving space of the housing and connected to the second display to rotate the second display, wherein, while the second display is rotated, a portion of the second display may overlap the first display.
