Vehicle Cabin Ceiling Display for Immersive Media and Natural Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle media systems fail to provide an immersive media experience for occupants, relying on external visual and auditory experiences that are often poor, especially in unfavorable traffic or weather conditions, leading to a less enjoyable ride.
Innovation Solution
A moodroof display system that uses the vehicle cabin ceiling as a display space, utilizing sensors to determine states such as weather and occupant emotions, and displaying media content on moodroof displays or projection surfaces, allowing the ceiling to remain open for natural light and air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If displays are placed on dashboard and headrests, then vehicle information can be displayed to occupants, but the visual experience is not immersive and occupies limited space
Solution Approach 1:
The patent transitions from traditional 2D dashboard and headrest displays to a 3D immersive display system that projects images onto the ceiling surface and uses spatial audio technology. This dimensional change creates a virtual reality environment that surrounds occupants, providing both larger effective display area and immersive visual experience simultaneously.
Solution Approach 2:
The system embeds multiple display surfaces and audio elements within the vehicle cabin structure. The ceiling acts as a canvas for projected images, while speakers are integrated into the cabin walls and ceiling, creating a nested configuration that maximizes space utilization and creates an immersive environment without adding external bulk.
2Adaptability or versatility
If ceiling is closed to provide display space, then immersive media content can be displayed, but natural light and air flow are blocked
Solution Approach 1:
The ceiling is designed as a dynamic structure that can transition between open and closed states. When media content needs to be displayed, the ceiling closes to provide the projection surface. When natural light and air flow are desired, the ceiling opens. This dynamic adaptability allows the system to switch between different functional states based on occupancy needs.
Solution Approach 2:
The ceiling serves multiple functions: it acts as a structural element for the vehicle, a projection surface for media displays, and a controllable barrier for light and air flow. This multi-functionality allows a single component to address both the media display requirement and the natural lighting requirement without needing separate dedicated structures.
3Reliability
If conventional displays are used, then vehicle information can be presented, but the experience is less enjoyable in unfavorable traffic or weather conditions
Solution Approach 1:
The system introduces a virtual reality intermediary environment that mediates between the occupants and the external environment. Instead of directly experiencing unfavorable external conditions through conventional displays, occupants are presented with a controlled virtual environment that can compensate for or replace the external visual experience, maintaining information delivery while shielding from environmental harm.
Solution Approach 2:
The system converts the limitation of being enclosed in a vehicle (which normally isolates occupants from enjoyable external environments) into a benefit by creating a controlled virtual reality space. The enclosure that previously prevented immersive experience now becomes a contained environment where virtual reality can be effectively delivered, transforming the harmful isolation into a beneficial immersive medium.

AI summary
Techniques for an augmented media experience in a vehicle cable include a first display surface positioned on a ceiling of the vehicle cabin, a second display surface positioned on the ceiling of the vehicle cabin, a memory storing a media application and a processor coupled to the memory. The first display surface is movable relative to the second display surface. The processor, when executing the media application performs the steps of deploying the first display surface to a deployed position where the first display surface is positioned between a first glass panel in a ceiling of the vehicle cabin and an interior of the vehicle cabin and displaying media content in the vehicle cabin using the first display surface and the second display surface.
