Motor Vehicle Camera Carrier Device Spring Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier devices for motor vehicle windshields face challenges in accurately positioning camera housings due to complex mounting processes and difficulty in aligning cameras relative to the base plate and windshield, leading to potential instability and increased cone of vision size.
Innovation Solution
A carrier device with a base plate secured to the windshield, featuring holding elements with spring elements that press directly onto rod-shaped components of the camera housing, allowing for precise positioning and reduced cone of vision by minimizing the distance between the camera and windshield, and utilizing three holding elements for stable mounting and adjustable orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring elements are mounted on the base plate and frame to press the camera housing, then the camera housing can be secured, but the mounting process becomes complex and positioning becomes difficult
Solution Approach 1:
The holding element is formed as an integral unit with the base plate, combining the base plate and holding element into a single component. This eliminates the need for separate mounting of holding elements and reduces the number of assembly steps, thereby simplifying the mounting process while maintaining secure camera housing attachment
Solution Approach 2:
The spring element is extracted from the complex frame structure and integrated directly into the holding element that is formed as one piece with the base plate. This extraction and integration simplifies the overall structure by reducing the number of separate components and making the mounting process more straightforward
2Reliability
If spring elements and curved leaf springs are used to secure the camera housing, then the housing can be clamped, but precise positioning of the camera relative to the base plate becomes difficult
Solution Approach 1:
The holding element with spring element is pre-formed as an integral part of the base plate during manufacturing. This preliminary integration ensures that the holding element is precisely positioned relative to the base plate before the camera housing is even installed, eliminating positioning difficulties that would occur with separate mounting components
Solution Approach 2:
By merging the holding element and base plate into a single integral component, the patent eliminates the positioning alignment issues that arise when separate components are assembled. The unified structure ensures precise and consistent camera positioning relative to the base plate
3Ease of manufacture
If the camera is positioned farther from the pane, then the camera housing can be easily mounted, but the cone of vision diameter increases
Solution Approach 1:
The patent replaces complex mechanical clamping systems with spring elements that provide secure attachment while allowing the camera housing to be positioned closer to the pane. The spring mechanism provides sufficient holding force with simpler construction, enabling reduced camera-to-pane distance without compromising mounting ease
Solution Approach 2:
The spring element design allows for adjustment of the pressing force and positioning characteristics, enabling optimization of the camera-to-pane distance. By modifying spring parameters (material, dimensions, pre-compression), the system achieves both easy mounting and reduced cone of vision diameter

Function Achieved in This Case
Enables improved camera positioning with reduced wobbling, precise alignment, and a smaller cone of vision, allowing for a smaller camera housing footprint and cap size, while applying forces only to the rod-shaped components, ensuring stable and defined camera placement.
Implementation Method 1
at least one spring element, which is formed to apply pressure directly to a rod-shaped component
Data Source
AI summary
A carrier device for attachment to a pane of a motor vehicle is disclosed. The carrier device has a base plate which is able to be secured to the pane, on which base plate a carrier arrangement is formed to hold a housing of at least one camera. The carrier arrangement includes at least one holding element having at least one spring element which is designed to apply pressure to a rod-shaped component which is arranged on the housing of the camera and which protrudes beyond a wall of the housing, the pressure acting in the direction towards the second side of the base plate. A pane of a motor vehicle on which such a carrier device is placed is also disclosed.
