Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices are often mounted in fixed locations within the vehicle interior, failing to meet the viewing needs of occupants in different positions.
Innovation Solution
A display device with a track providing an arc-shaped trajectory and drive mechanisms that allow the display screen to move along varying curvatures and flip to desired positions, using motors and lead screws for synchronized movement and flipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is fixedly mounted in the vehicle interior, then the mounting structure is simple and stable, but the viewing needs of occupants in different positions cannot be met
Solution Approach 1:
The display device is transformed from a fixed static mounting to a dynamic movable system. The display screen can move along an arc-shaped trajectory and flip to different positions, allowing it to adapt to various viewing angles and occupant positions while maintaining a relatively simple overall structure through controlled motion mechanisms.
Solution Approach 2:
The mounting structure is divided into multiple independent components including a track system, drive mechanisms, and link mechanisms. This segmentation allows each component to perform its specific function (positioning, driving, connecting) independently, achieving complex adaptive movement through coordinated simple parts rather than a monolithic complex structure.
2Adaptability or versatility
If the display device is mounted on the roof to improve viewing angles, then the viewing needs of different positions can be met, but the device cannot be easily adjusted or repositioned
Solution Approach 1:
The display device incorporates drive mechanisms that enable dynamic adjustment along the arc-shaped track and flipping motion. This allows the display to be easily repositioned and adjusted to different viewing angles, transforming a static roof-mounted display into a dynamically adjustable system that maintains ease of operation while improving viewing adaptability.
3Adaptability or versatility
If the display screen is made movable to accommodate different viewing positions, then viewing needs are met, but the mounting structure becomes more complex
Solution Approach 1:
The complex movement system is segmented into distinct functional modules: the track provides the arc-shaped trajectory, drive mechanisms generate motion, and link mechanisms connect components. This modular segmentation manages complexity by assigning specific functions to separate components that work together, rather than requiring a single complex integrated system.
Solution Approach 2:
The track is designed with an arc-shaped trajectory having varying curvature that matches the roof contour. This curved geometry allows the display to move naturally along a predetermined path, simplifying the control requirements compared to linear or multi-axis movements, while still achieving diverse viewing angles through the arc motion and flipping capability.

AI summary
The present invention relates to a display device for an interior space of a vehicle and a vehicle comprising the same. The display device comprises a display screen; a track configured to provide an arc-shaped trajectory having a varying curvature; and first and second drive mechanisms, each of the first and second drive mechanisms being connected to the display screen and movably mounted to the track. The display device is configured to drive the display screen to move along the arc-shaped trajectory by making the first and second drive mechanisms move synchronously along the track; and drive the display screen to flip by keeping one of the first and second drive mechanisms fixed at either position on the track and moving the other drive mechanisms along the track. The display device is able to meet the viewing needs of people located at different locations in the vehicle, thus enhancing driving and riding experience.
