Retractable Vehicle Display Layout for Space and Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices have limited space utilization due to fixed installation positions, require separate accommodation spaces for larger displays, and inefficiently use power as the entire screen is operated regardless of the display's exposure.
Innovation Solution
A flexible display device for vehicles that includes a casing with an opening, a retractable or extendable display part, a display driver for moving the display part, and a display winder for winding the display part based on its movement. The device allows for multiple extension modes and includes sensors to detect the display's state and control its exposure.
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 is limited and forward visibility decreases as display size increases
Solution Approach 1:
The display device transitions from a fixed installation to a movable one, allowing the display to be repositioned or retracted as needed. The housing can move the display between an extended state (visible to driver and passenger) and a retracted state (stored in accommodation space), providing dynamic adaptability to different usage scenarios and improving space utilization.
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 limits space utilization
Solution Approach 1:
The display device is nested within the housing structure, with the accommodation space integrated into the housing rather than being a separate component. The display can be retracted into the housing when not in use, allowing the accommodation function to be nested within the existing vehicle dashboard structure, thereby minimizing additional space requirements.
3Illumination intensity
If the entire screen is operated in LCD mode, then the display is always visible, but power consumption is inefficient as all power is used regardless of display exposure
Solution Approach 1:
The display device dynamically adjusts its operational state based on exposure needs. The housing can extend the display to full visibility when needed and retract it when not needed, allowing the system to optimize power consumption by controlling the display's active state according to actual usage requirements rather than maintaining constant full-power operation.

AI summary
A flexible display device for a vehicle includes a casing having an opening, a display part to be retracted or extended into or out of the casing through the opening, a display driver configured to move the display part, and a display winder configured to wind the display part based on movement of the display part.
