Extendable Vehicle Display Screen for Content Transfer Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in motor vehicles face issues where moving display content from one screen to another often results in the original content being covered or reduced in size, distracting the driver and compromising visibility of important information.
Innovation Solution
Incorporating an extendable screen that can be shifted between retracted and extended positions, allowing display content to be moved without altering the original content's size or visibility, using a control unit to activate the adjustment device based on user actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If display content is moved from the second screen to the first screen, then the moved content becomes visible on the first screen, but the original content of the first screen is covered or reduced in size
Solution Approach 1:
The patent extends the display area by projecting an extendable screen from the first screen in a direction perpendicular to its surface, transforming a 2D display problem into a 3D spatial solution. This allows multiple display contents to be shown simultaneously without overlapping or reducing visibility of original content.
Solution Approach 2:
The display system is segmented into a first screen, an extendable screen, and a second screen that can function independently. When content is moved to the first screen, the extendable screen provides additional display area, effectively segmenting the display tasks across multiple surfaces to prevent content overlap and driver distraction.
2Area of stationary object
If the display area is extended to show moved content, then both original and moved content can be displayed, but the device complexity increases
Solution Approach 1:
The extendable screen is nested within or integrated with the first screen housing, allowing it to be stored compactly when not in use and deployed only when needed. This nesting approach increases display area on demand while minimizing the permanent structural complexity and space requirements.
Solution Approach 2:
The extendable screen incorporates an adjustment device that allows dynamic changing of the display area based on operational needs. The screen can extend and retract or rotate to different positions, providing flexible display capacity without requiring a permanently complex multi-screen configuration.

AI summary
The examples may relate to a method for displaying display content on an extendable screen and to a display device for a motor vehicle. The display device may include at least a first and a second screen, configured to present respective display contents. The extendable screen may be arranged in a housing of the display device and configured to able to be shifted by an adjustment device between an extended position, in which the extendable screen is extended out of the housing, and a retracted position, in which the extendable screen is recessed in the housing. The display device may include a control unit configured to activate the adjustment device to shift the extendable screen into the extended position, and to display the display content on the extendable screen, when a user action for moving display content from the second screen onto the first screen is detected.
