Flexible Vehicle Display Pivot Arm for Compact Stowage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with flexible screens face challenges such as increased space requirements, limited adaptability to changing installation conditions, and wear due to guiding over rollers, while also suffering from distorted display content and visibility issues.
Innovation Solution
A display apparatus featuring a flexible screen device and a pivot mechanism with a motor and pivot arm, allowing the screen to be bent along a circular arc for stowage and deployed variably for use, with a carrier layer and display layer composite providing structural flexibility and inherent stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen device is guided over a roller for movement, then the screen can be transported from stowed to use position, but this leads to increased wear of the rear side of the screen
Solution Approach 1:
A flexible support structure with inherent stiffness is introduced as an intermediary between the screen device and the housing. This support structure assumes the screen device in a curved configuration in the retracted position and in a substantially planar configuration in the deployed position, thereby eliminating the need for roller guidance and preventing screen wear while enabling smooth transitions between positions
2Volume of moving object
If the screen device is bent along a circular arc for stowage, then space requirements are reduced, but the display surface becomes distorted and less visible
Solution Approach 1:
The support structure is designed to be flexible enough to assume a curved configuration during stowage but maintains sufficient inherent stiffness to transition to and hold a substantially planar configuration during deployment. This dynamic adaptability allows the screen to achieve both compact stowage and distortion-free display visibility
3Ease of manufacture
If the display apparatus is designed with fixed dimensions, then construction is simplified, but adaptability to changing installation conditions is limited
Solution Approach 1:
The flexible support structure with inherent stiffness enables the display apparatus to adapt to different installation conditions by allowing variable deployment positions. The structure can assume different curved configurations during stowage and different planar configurations during deployment, providing versatility without requiring complex adjustable mechanisms
Solution Approach 2:
The support structure's ability to change its configuration parameters (curved vs. planar, different deployment angles) allows the display apparatus to adapt to varying installation conditions. The inherent stiffness of the support structure enables these parameter changes while maintaining structural integrity and screen visibility

AI summary
A display device includes a flexible screen device and a pivot mechanism. The flexible screen device is movable between a stowed position, in which the flexible screen device is bent along a circular arc and stowed in a housing, and a use position, in which the flexible screen device protrudes at least partially from the housing. The pivot mechanism is configured to move the flexible screen device between the stowed position and the use position, and includes a motor and a pivot arm. The pivot arm is rotatably mounted on a foot region of the flexible screen device so as to be pivotable about an axis of rotation. The pivot arm is configured to receive a torque from the motor to move the foot region along the circular arc. The flexible screen device is thereby alternately pushed into the use position and pulled into the stowed position.
