Foldable Display Apparatus for Motor Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern motor vehicle displays face challenges with space efficiency and user handling due to fixed display sizes and the limitations of elastic or flexible screens that require tension and may snap back unexpectedly, causing visual confusion and safety issues.
Innovation Solution
A foldable display apparatus with a folding device that allows the display surface to be enlarged or reduced without elastic resistance, using a hinge or swinging mechanism that can be controlled electronically or mechanically, allowing for adjustable display angles and reduced construction space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size display screen is used in motor vehicles, then the display content is stable and reliable, but the construction space is wasted and the display cannot be adapted to different usage scenarios
Solution Approach 1:
The display surface device is divided into multiple display regions that can be independently folded or swung relative to each other. The folding device creates separable segments that can be configured in different arrangements, allowing the display to adapt between compact storage and expanded viewing areas without requiring a fixed large structure throughout.
Solution Approach 2:
The display surface device transitions from a static fixed-size screen to a dynamic reconfigurable structure. The folding device enables the display regions to move between folded and unfolded states, allowing the display size and configuration to change based on operational requirements, thus improving adaptability while reducing space when compact.
2Ease of operation
If an elastic or flexible screen is used to enable folding, then the display can be compacted when not in use, but the screen is under tension and may snap back unexpectedly causing visual confusion and safety issues
Solution Approach 1:
The patent replaces elastic or flexible materials that rely on tension and elastic recovery with a rigid folding mechanism. Instead of using material elasticity to enable folding, the invention uses a mechanical folding device with hinges or swinging joints that allow controlled movement without continuous tension, eliminating the risk of unexpected snap-back while maintaining foldability.
Solution Approach 2:
The invention changes the fundamental parameter of how folding is achieved - from elastic deformation under tension to rigid body rotation around hinges. This parameter change transforms the folding mechanism from one that stores elastic energy to one that uses controlled mechanical rotation, improving reliability while maintaining ease of operation.
3Loss of information
If additional screens are added to provide more display content, then the information availability increases, but visual confusion arises and rapid locating of certain display content becomes difficult
Solution Approach 1:
The foldable display surface device serves multiple functions: it can be fully unfolded to provide maximum display area for comprehensive information, partially folded to highlight specific regions, or fully folded for compact storage. This single multi-functional device replaces the need for multiple separate screens, maintaining information availability while improving content locatability through controlled configuration.
Solution Approach 2:
The dynamic folding capability allows the display to adapt its configuration based on information priority. Important or time-sensitive content can be displayed in always-visible regions that remain accessible even when partially folded, while secondary content can be in folded-away sections. This dynamic reconfiguration improves ease of locating important information compared to static multi-screen arrangements.

AI summary
A display device has a display surface with at least two display regions for displaying display content, and a folding device configured to fold the display surface. The folding device can optionally have a rail element which runs parallel to a direction of extent of one of the display regions and is arranged displaceably parallel thereto. A lever element of the folding device has a first end arranged on the rail element, and a second end with at least one holding element arranged on a foldable display region.
