Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in vehicles are limited by rigid designs, restricting size and position flexibility, and cannot dynamically change size in both height and width to accommodate various applications and limited installation space.
Innovation Solution
A flexible display surface element using a kinematic mechanism and restoring element, such as a spring, allows the display to be clamped and stretched, enabling adjustable size and form factor between minimum and maximum sizes, with a control unit managing adjustments based on usage modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid display is permanently installed in a vehicle, then the display provides stable structural support and easy installation, but the display size and position cannot be dynamically adjusted, limiting adaptability to different applications and installation spaces
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid, fixed display into a flexible, adjustable display surface that can dynamically change its size and shape. The display surface element is made flexible and can be extended or retracted using a kinematic mechanism, allowing it to adapt to different installation spaces and application requirements while maintaining structural integrity through controlled movement rather than rigid construction
Solution Approach 2:
The patent implements the nesting principle by designing the display surface element to be rollable and storable within a limited installation space. When not in use or when a smaller display size is required, the flexible display surface can be rolled up or folded into a compact form that occupies minimal space, similar to how nested dolls store smaller objects within larger ones. This allows the display to provide both large and small display configurations from a single integrated structure
2Area of stationary object
If the display surface is extended in only one direction (height), then the installation space requirement is reduced, but the display area expansion is limited and cannot achieve panorama format
Solution Approach 1:
The patent applies the dimensionality change principle by enabling the display surface to expand not only in the vertical direction (height) but also in the horizontal direction (width). This is achieved through a kinematic mechanism that allows bidirectional extension of the flexible display surface, transforming it from a unidimensionally adjustable display to a two-dimensionally adjustable display. This enables the display to achieve panorama format and various aspect ratios, significantly increasing the display surface area without proportionally increasing the installation space footprint
3Adaptability or versatility
If a flexible display surface element is used to enable size adjustment, then adaptability increases, but the display surface may develop wrinkles and visibility may be compromised
Solution Approach 1:
The patent implements the flexible shells and thin films principle by using a flexible display surface element that can be dynamically adjusted in size and shape. This flexible surface is designed to maintain sufficient flatness and tension during operation to ensure clear visibility of displayed content, while still allowing for controlled extension and retraction. The flexibility enables the display to adapt to different formats and installation configurations without compromising the structural integrity or visual quality of the display surface
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for continuous adjustment of display surface size and format, reducing installation space requirements and minimizing wrinkles, while ensuring clear visibility and protection of the display content, suitable for various vehicle usage modes.
Implementation Method 1
The display surface element is not rolled up in a starting position, thus in the position in which a smaller display surface is available than in a panorama position, but rather clamped or stretched by a second kinematic mechanism and a restoring element, for example a spring.

AI summary
A display device may include a flexible display surface element having a display surface, and an adjustment unit which includes a clamping element in form of a rod and arranged such that the rod moves in a first adjustment direction, a restoring element arranged on the clamping element, and a deflection element in form of a rod. A first side edge of the display surface element is arranged on a length of the clamping element. A second side edge of the display surface element opposite the first side edge is connected to the clamping element via the restoring element. A surface of the display surface element is bent and has a bending region. A length of the deflection element extends in same direction as the clamping element, the deflection element extends within the bending region of the bent display surface element and is arranged such that the deflection element moves in a second adjustment direction to change a distance between the deflection element and the clamping element.
