Vehicle Camera Mounting With Integrated Cleaning Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of optical systems, including camera and cleaning devices, on vehicle body elements is complex and prone to errors due to the need for precise alignment and secure mounting, especially when exposed to environmental factors like rain and dust that degrade image quality.
Innovation Solution
A mounting arrangement that includes a housing element with flexible tongues for securing the optical device, a fluid projection device integrated with the housing, and a fixing element with snap tabs and latching feet for easy assembly and secure attachment to the vehicle body, allowing for pre-assembly and simple snap-on installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera and cleaning device are directly mounted to a support, then the assembly is secure and stable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The camera housing and cleaning device are integrated into a single unified structure where the cleaning device is mounted on the camera housing itself. This merging of components allows them to be installed as one unit, simplifying the assembly process while maintaining secure mounting through the integrated design with multiple attachment points and interlocking mechanisms.
2Reliability
If the camera housing and fluid spray device are directly mounted to a support, then the mounting is secure, but the assembly requires precise alignment and is prone to errors
Solution Approach 1:
The mounting system is divided into modular components with standardized interfaces. The camera housing and cleaning device are separate modules that connect through predefined mounting points and alignment features, allowing for easier assembly without requiring high precision alignment while maintaining secure attachment through the segmented design with multiple connection points.
3Device complexity
If the optical system is exposed to rain and dust, then the system remains simple and accessible, but image quality degrades due to contamination
Solution Approach 1:
The cleaning device is integrated directly onto the camera housing, allowing it to self-clean the optical elements without requiring external cleaning systems. The fluid spray device is positioned to directly target the lens and sensor areas, enabling the system to maintain its own optical cleanliness autonomously while keeping the overall system design simple and compact.
