Retractable Vehicle Screen Layout for Large Display in Tight Cabin Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle entertainment systems with rigid mechanical parts and electronic components occupy significant interior space, making it difficult to achieve an ideal retractable design that enhances passenger experience while conserving space.
Innovation Solution
A vehicle device featuring a light-emitting unit and a screen, where the screen is stored within the vehicle body and can be extended to provide a vertical length that optimally projects images without occupying excessive space, using adjustable angles and materials like semi-transparent screens and adjustable reflectance layers to ensure clear viewing and efficient use of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If traditional rigid mechanical displays are used, then the display area is large, but the interior space of the vehicle is significantly occupied
Solution Approach 1:
The patent transitions from a traditional planar display to a three-dimensional retractable display system. The display screen can be extended from a compact stored position within the vehicle body to a fully extended position where it projects outward, utilizing the third dimension (depth/extension) to provide a large display area without permanently occupying interior space. The screen is disposed at an angle relative to the vehicle body and can be adjusted along a projection direction, effectively using spatial dimensionality to resolve the contradiction between display size and space occupation.
Solution Approach 2:
The display system is designed to be dynamically adjustable rather than fixed. The screen can be retracted into or extended from the vehicle body according to operational needs. The angle of the screen relative to the vehicle body can be adjusted, and the projection distance can be varied. This dynamic capability allows the system to provide a large display area when needed while returning to a compact state to minimize interior space occupation when the display is not in use.
2Length of moving object
If the screen is extended to provide a large vertical length, then the viewing experience is enhanced, but the retraction space within the vehicle body is increased
Solution Approach 1:
The display screen is designed to be nested within the vehicle body when not in use. The screen can be fully retracted into a storage compartment or housing structure integrated into the vehicle body, similar to a nested doll configuration where the display element fits within the available internal space. This nesting approach allows for a long screen when extended while minimizing the space required when retracted.
Solution Approach 2:
The screen is disposed at an angle relative to the vehicle body rather than parallel to it. This angular configuration allows the screen to extend outward in a direction that utilizes available external space more efficiently. By projecting at an angle, the screen achieves a large vertical length and display area without requiring proportional increases in the retraction space within the vehicle body, as the extended position leverages the angular geometry to optimize space utilization.

AI summary
A vehicle device is provided, which includes a light-emitting unit and a screen separately disposed on a vehicle body. In a first state, the screen is stored in a first portion. In a second state, at least a part of the screen is stretched out of the first portion, and the screen has a vertical length of H, which satisfies: H=[(L−d)*tan(θd)]+[(L−d)*tan(θu)] and H<Hv. L is a first horizontal distance between a viewing point and a first barrier element. d is a second horizontal distance between the screen and the first barrier element in the second state. θd is a viewing angle below the horizontal plane when observes from the viewing point to the screen, with θd≤70 degrees. θu is a viewing angle above the horizontal plane when observes from the viewing point to the screen. Hv is a height of the space inside the vehicle.
