Rollable Vehicle Display Adjusting Screen Size for Driving Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle display devices obstruct the driver's field of vision and require increased screen size for more information, complicating the vehicle's front area as various control systems are installed, especially in autonomous driving modes.
Innovation Solution
A processor-controlled rollable display system that adjusts screen size based on vehicle driving conditions or user input, allowing for customizable display sizes in autonomous and normal driving modes, including options for navigation, multimedia, and rear monitoring functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the screen size of the vehicle display device is increased to provide more information to the driver, then the information display capability is improved, but the display obstructs the driver's field of vision
Solution Approach 1:
The display device employs a rollable screen that can dynamically change its size and shape between extended and retracted states. The screen transitions from a large flat configuration that provides comprehensive information display to a compact rolled-up state that minimizes visual obstruction, allowing the system to adapt its physical dimensions based on real-time driving conditions and information display requirements
Solution Approach 2:
The display device changes its physical parameters (size, shape, position) by rolling the screen into different configurations. The screen can transform from a large rectangular display to a compact cylindrical or folded form, fundamentally altering its spatial occupation and visual impact on the driver's field of vision while maintaining the same display content capability
2Quantity of substance
If the screen size of the vehicle display device is increased, then more information can be displayed, but the front area of the vehicle becomes more complex and requires more installation space
Solution Approach 1:
The rollable display mechanism allows the screen to be nested within itself by rolling into a compact form factor. When not in use or when minimal display is required, the large screen is rolled into a small cylindrical or folded package that fits within a compact housing, significantly reducing the space required in the vehicle's front area while maintaining the capability to expand to a large display when needed
Solution Approach 2:
The display system transitions from a static large-screen configuration to a dynamic rollable mechanism that can adjust its size and shape. This dynamic capability allows the display to be compact during autonomous driving or when information display is not needed, reducing the complexity and space requirements in the vehicle front area, and expand when comprehensive information display is required

AI summary
A device for controlling a vehicle display device may include: a processor to determine a vehicle driving condition, and adjust a screen size of the vehicle display device based on the determined vehicle driving condition; and a storage to store information determined by the processor.
