Flexible Vehicle Display Tensioning for Adjustable Panoramic Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in vehicles are limited by installation space and laws, restricting the size and position of rigid displays, and there is a need for more dynamic size adjustment that also considers the display's width, rather than just height, to accommodate various applications and aesthetics.
Innovation Solution
A flexible display surface element, such as an OLED screen, is used with a clamping and restoring mechanism that allows adjustment in both height and width, utilizing a kinematic system with a clamping element, deflection element, and restoring element to change the display's size and shape, enabling a panoramic format without rolling, which reduces material stress and visibility issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid display is permanently installed to provide a stable display surface, then the display structure is simple and stable, but the display size and position cannot be adjusted dynamically
Solution Approach 1:
The display surface element transitions from a static rigid structure to a dynamic flexible structure that can change its configuration. The flexible display surface element can be extended in the first direction and widened in the second direction, allowing dynamic adjustment of display size and shape according to different application scenarios.
Solution Approach 2:
The patent employs a flexible display surface element made of flexible material that can be bent, extended, and widened. This flexible film structure replaces the traditional rigid display panel, enabling the display to adapt to different sizes and shapes while maintaining structural integrity through the tensioning mechanism.
2Area of moving object
If the display surface is extended in one direction only to increase height, then the adjustment mechanism is simple, but the display cannot achieve panoramic format or significant area increase
Solution Approach 1:
The patent extends the display adjustment from one dimension (height only) to two dimensions by adding width adjustment capability. The flexible display surface element can be extended in the first direction (height) and simultaneously widened in the second direction (width), achieving panoramic format and significantly increasing the display area.
Solution Approach 2:
The kinematics system is designed to dynamically adjust both the extension and widening of the flexible display surface element, allowing the display to transition between various sizes and shapes including panoramic formats, providing versatile display capabilities.
3Volume of moving object
If a flexible display is rolled up to reduce size, then the display can be compacted, but material stress and visibility issues occur
Solution Approach 1:
Instead of rolling the flexible display into a compact coil, the patent uses a dynamic tensioning mechanism that keeps the display surface taut and flat during retraction. The clamping element and return element work together to maintain the display in a tensioned state, preventing material stress and visibility issues while still achieving compact storage.
4Area of moving object
If the display width is increased to achieve panoramic format, then the display area is enlarged, but more installation space is required
Solution Approach 1:
The patent employs a dynamic widening mechanism where the flexible display surface element can be extended in the width direction only when needed for panoramic format. During normal operation or when panoramic display is not required, the display maintains a compact width, significantly reducing the required installation space while still providing the capability for large-area panoramic display when needed.

Function Achieved in This Case
This solution allows for continuous adjustment of the display area, reducing installation space requirements and minimizing the risk of kinks or dirt accumulation, while maintaining clear visibility and protecting the material, enabling a wide range of display sizes and formats, particularly useful in vehicles where space is limited.
