Vehicle Flexible Display with Movable Roller Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices face challenges in minimizing interference with other dashboard components, maintaining a non-obstructive field of vision, and efficiently managing power consumption while providing a large display area, especially when their size and shape are not adaptable to varying usage scenarios.
Innovation Solution
A vehicle display device with a flexible design that includes a first frame coupled to the dashboard, a second frame movable vertically, and actuators allowing the display to change size and shape by moving upward, downward, and laterally, with rollers and moving bodies to support the flexible display, enabling it to expand and contract uniformly, thus optimizing space usage and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device is made large to provide more information, then the display area increases, but it interferes with other dashboard components and blocks the field of vision
Solution Approach 1:
The display device is designed with movable and expandable features, allowing it to dynamically adjust its size and position. The second frame can move vertically relative to the first frame, and the flexible display can expand horizontally using rollers and moving bodies, enabling the display to adapt between large and compact states based on usage requirements.
Solution Approach 2:
The flexible display is designed to be stored in a compact form within the dashboard when not in use. The display can be folded or rolled into a smaller configuration that nests within the dashboard structure, similar to a nested doll, and only expands to full size when needed for viewing.
2Object-affected harmful factors
If the display device is made movable to avoid blocking field of vision, then the field of vision improves, but the device complexity increases
Solution Approach 1:
The display device incorporates vertical movement capability through actuators that move the second frame relative to the first frame. This dynamic positioning allows the display to rise above the dashboard when needed and retract below when not in use, eliminating field of vision blocking while maintaining operational functionality.
3Area of moving object
If the flexible display is expanded to increase display area, then the information provision improves, but the tension uniformity and stability may be compromised
Solution Approach 1:
Rollers are introduced as intermediary components between the flexible display and the expansion mechanism. These rollers support the flexible display during horizontal expansion, distributing the mechanical stress uniformly across the display surface and preventing deformation or uneven tension that would occur with direct mechanical attachment.
4Volume of moving object
If the display device is kept compact in dashboard, then the space utilization improves, but the display area available for information decreases
Solution Approach 1:
The flexible display incorporates expandable sections with rollers and moving bodies that enable horizontal expansion. When space is available, the display can extend to provide a large viewing area. When space is constrained, the display can be contracted to a compact form that fits within the dashboard, dynamically adapting to spatial requirements.

AI summary
A display device for a vehicle includes a first frame configured to be coupled to a dashboard of the vehicle, a second frame configured to move vertically relative to the first frame, and a flexible display having a first area that extends along the second frame and defines a flat surface and a second area that is configured to extend from the first area, where the display device is configured to vary a shape of the second area. The display device further includes a first roller that extends in an upward-downward direction and that supports an inner surface of the flexible display to allow the second area to be curved around the first roller, a first moving body is coupled to the second area, and a second actuator configured to move the first roller and the first moving body laterally relative to the second frame.
