Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display arrangement is provided with a kinematic design for folding in and out, then the display arrangement can be adjusted to provide entertainment programs, but the space requirement and structural complexity increase
Solution Approach 1:
The patent combines multiple functions (folding, pivoting, locking, and adjusting) into a single integrated lever mechanism. The lever mechanism incorporates guide sliders, pivot levers, and locking elements that work together to achieve both the folded-in and folded-out positions while maintaining a compact structure. This merging of functions reduces the overall space requirement compared to separate mechanisms for each function.
Solution Approach 2:
The display arrangement employs a dynamic lever mechanism that transitions between different states (folded-in and folded-out) through controlled movement. The guide sliders move along guide rails, and the pivot levers rotate about pivot axes, enabling the display to dynamically adjust its position. This dynamic design allows the display to occupy minimal space when folded in while providing full adjustment capability when folded out.
2Adaptability or versatility
If a kinematic display arrangement is implemented, then the display can be folded in and out, but the device complexity increases
Solution Approach 1:
The lever mechanism serves multiple functions simultaneously: it guides the folding motion through guide sliders, enables pivoting through pivot levers, provides locking through locking elements, and allows for adjustment of the display position. This multi-functionality reduces the need for separate mechanisms, thereby reducing overall device complexity despite the kinematic capabilities.
Solution Approach 2:
The lever mechanism is segmented into distinct functional components (guide sliders, pivot levers, locking elements) that are coupled together in a coordinated manner. Each component has a specific function, but they work together as an integrated system. This segmentation allows for easier manufacturing and assembly while maintaining the complex kinematic functionality.
3Volume of moving object
If a space-saving arrangement is used, then the installation space is reduced, but the reliability and security of display adjustment may be compromised
Solution Approach 1:
The locking elements are designed to automatically engage at predetermined positions during the folding and pivoting motion. The guide sliders and pivot levers are configured so that the locking action occurs naturally as part of the adjustment sequence, ensuring the display is securely locked in the desired position without requiring additional space for separate locking mechanisms.
Solution Approach 2:
The lever mechanism acts as an intermediary between the drive unit and the display arrangement, transmitting and controlling the motion while ensuring reliable positioning. The guide sliders and pivot levers mediate the movement, and the locking elements provide secure engagement, all within a compact structure that maintains reliability.

AI summary
A device for adjusting a display arrangement for a vehicle roof includes a lever mechanism for pivoting open and in, and for moving the display arrangement with movable guide sliders and pivot levers which are coupled to one another, a spring element with two spring arms, a fixed spring guide element with a guide portion and a first end stop, wherein an end portion of the first spring arm engages in the guide portion and can be moved inside the guide portion along the guide rail, and a rotatably mounted locking element which is coupled to the second guide slider. The locking element can be transferred by means of the first guide slider and the spring element from a first state in which the display arrangement is folded in and locked, into a second state in which the display arrangement is unlocked and can be pivoted open or pivoted in.
