Snap-fit Self-cleaning Vehicle Camera Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle camera cleaning systems are bulky, expensive, and difficult to service due to complex mounting mechanisms that occupy space and are unsightly, hindering the self-cleaning functionality of camera lenses.
Innovation Solution
A snap-fit configuration for the cleaning assembly that allows easy coupling and decoupling with the camera housing, utilizing flexible and rigid coupling members to securely attach and detach the fluid spray nozzle assembly, enabling efficient and space-saving self-cleaning of camera lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex mounting brackets are used to attach the cleaning nozzle, then the cleaning assembly is securely fixed, but the device becomes bulky and occupies valuable space
Solution Approach 1:
The cleaning assembly is divided into separable components (nozzle assembly and camera housing) that can be independently manufactured and assembled. The mounting bracket is designed as a separate element that interfaces with both components, allowing for modular assembly and reduced overall volume while maintaining secure fixation.
Solution Approach 2:
The cleaning nozzle assembly is integrated within or alongside the camera housing structure, with the mounting bracket nesting the cleaning components into the existing camera assembly footprint. This allows the cleaning function to be added without significantly increasing the overall volume occupied by the camera system.
2Strength
If complex mounting brackets are used to attach the cleaning nozzle, then the cleaning assembly is securely fixed, but the device becomes expensive and unsightly
Solution Approach 1:
The mounting bracket is designed to serve multiple functions: securing the cleaning nozzle, providing fluid pathway connections, and potentially serving as a structural element of the camera housing itself. This multi-functionality reduces the need for additional separate components, lowering manufacturing costs while maintaining secure fixation.
Solution Approach 2:
The mounting bracket is integrated with the camera housing structure rather than being a separate external component. The cleaning assembly is merged into the existing camera housing design, eliminating the need for additional brackets and reducing both manufacturing complexity and visual appearance issues.
3Reliability
If the cleaning assembly is permanently integrated, then the cleaning function is reliable, but servicing and removal of the nozzle becomes difficult
Solution Approach 1:
The mounting bracket incorporates reversible mounting mechanisms such as threaded fasteners, snap-fit connections, or bayonet mounts that allow the cleaning nozzle to be easily attached and detached. This dynamic mounting system maintains secure fixation during operation while enabling simple removal for servicing or replacement.
Solution Approach 2:
The cleaning nozzle is designed as a separable module that can be independently removed from the camera housing through the mounting bracket interface. This segmentation allows the nozzle to be serviced, cleaned, or replaced without affecting the permanent integrated components of the camera system, maintaining both reliability and ease of repair.
