Vehicle Display System with Movable Screen for Obstruction Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems are not readable in all driving situations due to obstruction by the steering wheel or other objects, posing a risk to driving safety as critical information may not reach the driver.
Innovation Solution
A system comprising a first immovable display and a second movable display with a scanning device and processing unit to determine the driver's position and display content obscured by the second display, ensuring that obscured information is dynamically presented on the second display to maintain driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single display device is used in the vehicle, then the device complexity is reduced, but the information accessibility to the driver deteriorates when the display is obscured by the steering wheel or other objects
Solution Approach 1:
The display system is segmented into a first display device and a second display device. The first display device provides primary information, while the second display device acts as a supplementary display that becomes active when the first display is obscured. This segmentation allows the system to maintain information accessibility without requiring a completely redundant display system.
Solution Approach 2:
The second display device serves as an intermediary solution between the driver and the obscured first display device. When the steering wheel or other objects block the primary display, the second display device mediates by providing the same information through an alternative path, ensuring the driver continues to access critical information.
2Device complexity
If the first display is positioned at a fixed location, then the device complexity is reduced, but the information accessibility deteriorates when the driver moves or the steering wheel rotates
Solution Approach 1:
The system introduces dynamic behavior through the second display device, which is movable or rotatable unlike the fixed first display device. When the driver moves or the steering wheel rotates, the second display device can adjust its position or orientation to maintain visibility, creating a dynamic adaptation to changing driving conditions without overcomplicating the overall system.
Solution Approach 2:
The system changes the parameter of display visibility by activating the second display device when the first display becomes obscured. This parameter change approach allows the system to adapt to different driving situations (steering angle, driver position) without physically reconfiguring the entire display system, maintaining simplicity while improving accessibility.
3Loss of information
If the second display is made transparent to minimize obstruction, then the information accessibility is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The second display device utilizes transparent or translucent display technology that allows light to pass through, making the display itself partially transparent. This color/optical property change enables the display to provide information without completely blocking the view of the first display or the road, reducing the need for high manufacturing precision while maintaining visibility.
Solution Approach 2:
The second display device employs composite material structures that combine transparent display components with supporting elements. This composite approach allows the display to maintain structural integrity and functionality while achieving the desired transparency level, balancing manufacturing feasibility with information accessibility.

AI summary
An apparatus for providing information on board a vehicle includes a first display; a second display; a scanning device for capturing a position of a person on board the vehicle; and a processing device. The processing device is configured to: determine a constellation in which the second display is located between the first display and the person; determine a display content of the first display that is covered by the second display; and provide the determined display content on the second display.
