Motor Vehicle Screen Adjuster With Single Spindle Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen adjustment devices in motor vehicles require multiple components and additional installation space, limiting flexibility and increasing complexity due to the use of spindle drives and levers, which adversely affect visibility and accessibility.
Innovation Solution
A screen adjustment device utilizing an electromotive drive unit and a positioning mechanism with a spindle drive and rail arrangement, minimizing components and installation space, allowing for smooth, play-free guidance and swiveling of the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two permanently mounted spindle drives and an additional lever are used to move and rotate the screen, then the screen can be adjusted between parking and operating positions, but additional installation space and additional components are required which limits flexibility
Solution Approach 1:
The patent combines the functions of two separate spindle drives and a lever into a single spindle drive mechanism. The screen is directly coupled to the spindle drive, eliminating the need for additional levers and reducing component count while maintaining the ability to adjust the screen between parking and operating positions.
Solution Approach 2:
The patent removes unnecessary components from the screen adjustment mechanism. By using a single spindle drive with direct coupling, the design extracts and eliminates the redundant lever and second spindle drive, reducing device complexity while preserving adjustment functionality.
2Ease of operation
If two permanently mounted spindle drives and an additional lever are used, then the screen can be adjusted, but additional installation space is required which is limited in the dashboard
Solution Approach 1:
The patent merges multiple adjustment functions into a single compact spindle drive mechanism, significantly reducing the installation space required in the dashboard while maintaining full screen adjustability between parking and operating positions.
Solution Approach 2:
Instead of using multiple distributed components (two spindle drives and a lever) that require scattered installation space, the patent inverts the approach by using a single centralized spindle drive with direct coupling, consolidating the mechanical footprint and optimizing dashboard space utilization.
3Stability of the object's composition
If the screen is guided in a groove on the back by means of a pin for stabilization, then the screen position is stabilized, but additional components are required which limits flexibility
Solution Approach 1:
The patent extracts and eliminates the pin and groove stabilization mechanism by implementing direct coupling between the screen and spindle drive. The screen is directly mounted to the spindle drive assembly, providing inherent stability without requiring separate guiding components.
Solution Approach 2:
The patent combines the stabilization function into the main spindle drive assembly itself. The screen is directly coupled to the spindle drive, integrating the support and stabilization functions into a single unified structure, thereby eliminating the need for separate pin and groove components.
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
Reduces the number of components and installation space, enhancing flexibility and visibility by eliminating fluttering and rattling noises while enabling larger adjustment angles with reduced susceptibility to vibrations.
Implementation Method 1
the screen adjustment device comprises at least one electromotive drive unit
Implementation Method 2
The spindle drive comprises at least one threaded spindle with a spindle nut coupled to it
Data Source
AI summary
A screen adjustment device for a motor vehicle is provided that comprises a screen reversibly movable between a parking position and at least one operating position and/or screen support for mounting such a screen. At least one electromotive drive unit generates an actuating force which causes an adjustment of the screen and/or screen support. A positioning mechanism guides the screen and/or screen support between the parking position and at least one operating position and transmits the actuating force. The positioning mechanism having at least one spindle drive with a threaded spindle and with a spindle nut arranged on it. The spindle drive being coupled to the screen and/or to the screen support and to the drive unit.
