Retractable Vehicle Display Support for Space and Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices have limited space utilization due to fixed installation positions, increased space requirements for larger displays, and inefficiencies in power usage since the entire screen operates regardless of exposure.
Innovation Solution
A flexible display device with a retractable and extendable design, featuring a display driver, a display winder, and a display support unit that includes a housing, a supporter, and a supporter fixture with a movable plate, lock plate, and cam mechanism to control the display's exposure and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a fixed display is installed in a vehicle, then the display can be positioned at a specific location, but the space utilization in the vehicle is limited and forward visibility decreases as display size increases
Solution Approach 1:
The patent implements a movable display device that can dynamically adjust its position along a guide mechanism, transforming from a fixed installation to a dynamic reconfigurable system. This allows the display to move between different locations (driver side, passenger side, or retracted) to optimize space utilization and forward visibility while maintaining adaptability to different usage scenarios
Solution Approach 2:
The display device utilizes a three-dimensional movement path along a guide, allowing it to transition between multiple spatial positions rather than being confined to a single fixed location. This dimensional mobility enables the system to optimize both space utilization and forward visibility by positioning the display in the most appropriate location for each usage scenario
2Adaptability or versatility
If a pop-up style movable display is used, then the display can be extended when needed, but a separate accommodation space is required which increases the overall size
Solution Approach 1:
The display device is designed to be nested within the dashboard structure when retracted, utilizing the existing dashboard volume rather than requiring a separate accommodation space. The guide mechanism and motor assembly are integrated into the dashboard, allowing the display to be stored compactly within the same volume that houses other dashboard components
3Area of stationary object
If the entire LCD screen operates regardless of exposure degree, then the full display area is available, but power efficiency decreases
Solution Approach 1:
The patent implements selective activation of display segments based on the actual usage scenario. The control unit can activate only the necessary portion of the display (e.g., only the driver-side portion when the driver needs information, or only the extended portion when the display is moved), rather than powering the entire screen. This local activation approach maintains full display area availability when needed while significantly reducing power consumption during partial usage

AI summary
The present disclosure relates a display device and a vehicle equipped with the display device. The display device may include a display driver configured for moving a display, a display winder operatively engaged to the display driver and configured for winding and unwinding the display according to the movement of the display, and a display support unit supporting the display. The display support unit may include a housing having an opening formed therein to allow the display to be retracted and extended, a supporter having a top end hinged to a top end portion of the display and supporting the display, and a supporter fixture fixing the supporter.
