Retractable Vehicle Display Panel With Arm Support for Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with large screens mounted on vehicle headlinings consume excessive power and are difficult to adjust to desired angles and arrangements, occupying valuable space.
Innovation Solution
A flexible display panel system with a housing, rollers, driving unit, and arm assembly that allows the panel to be drawn in and out, minimizing power consumption and enabling adjustable angles and arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire module of the display apparatus is moved to adjust the driving state, then the display apparatus can be positioned horizontally or vertically with the head lining, but a lot of power is consumed and it is difficult to provide the desired angle and arrangement
Solution Approach 1:
The display apparatus is divided into separate components: a movable display panel and a stationary housing. The display panel can be independently drawn in and out, allowing angle and arrangement adjustment without moving the entire module, thereby reducing power consumption while maintaining adaptability.
Solution Approach 2:
The display panel is designed to be dynamically adjustable through the drawing mechanism, enabling it to move between retracted and extended positions. This dynamic capability allows flexible positioning at various angles without requiring the entire module to be moved, optimizing both adaptability and energy efficiency.
2Area of moving object
If a large-screen display apparatus is mounted on the head lining, then various information and entertainment contents can be provided, but it occupies a lot of space inside the vehicle
Solution Approach 1:
The display panel is nested within the housing when not in use, drawn in to a retracted position. When needed, it is drawn out to provide a large display area. This nesting mechanism allows a large-screen display to be mounted on the head lining without permanently occupying excessive space, as the panel can be stored within the housing when not in use.
3Adaptability or versatility
If the display panel is made flexible to enable drawing in and out, then space utilization is improved and power consumption is minimized, but the panel requires support structures like arm assembly to maintain stiffness when drawn out
Solution Approach 1:
The display panel uses a flexible substrate that allows it to be drawn in and out of the housing. This flexibility enables space-saving retraction and reduces the need for rigid support structures during movement, while the arm assembly provides minimal support only when the panel is in the drawn-out position for display.
Solution Approach 2:
The support function is extracted from the entire mounting structure and concentrated into a specific arm assembly that only engages when needed. The arm assembly couples to the drawn-out display panel to provide stiffness only during the display state, rather than requiring continuous structural support, thereby reducing overall device complexity.

AI summary
A display apparatus for vehicle comprising: a display panel including a first surface designed to have at least one area that is flexibly deformed and display images and videos and a second surface that is a rear surface of the first surface; a housing installed on a head lining of the vehicle and having an internal space which the display panel is drawn into or out of; a plurality of rollers disposed inside the housing to guide a direction in which the display panel is drawn in or out; a driving unit providing force for the display panel to be drawn in or out; and an arm assembly coupled to at least a portion of the second surface to support the stiffness of the drawn-out display panel.
