Annular Camera Lens Cleaning Device with Integrated Spray Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera cleaning systems are inefficient due to either single spray nozzles with low distribution efficiency or multiple nozzles requiring separate supply lines, and they often obstruct the camera's field of view with spray nozzles positioned adjacent to or above the lens.
Innovation Solution
A cleaning device featuring an annular channel with multiple cleaning agent spraying elements, such as deflectors or spray nozzles, that surrounds the camera lens, allowing for efficient distribution of cleaning agents without individual supply lines for each nozzle and minimizing visual obstruction by adjusting the position and number of spraying elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple spray nozzles are used for cleaning the camera cover, then cleaning efficiency is improved, but device complexity increases due to requiring separate supply lines for each nozzle
Solution Approach 1:
The patent combines multiple spray nozzles into a single integrated cleaning device housing that receives one cleaning agent supply line. The housing distributes the cleaning agent to multiple nozzles internally, merging multiple functions into one component. This reduces device complexity by eliminating the need for separate supply lines for each nozzle while maintaining high cleaning efficiency through multi-nozzle spray distribution.
2Productivity
If spray nozzles are positioned adjacent to or above the camera objective, then cleaning coverage is improved, but the field of view is restricted
Solution Approach 1:
The patent positions the spray nozzles in an annular arrangement around the camera objective rather than directly above or adjacent to it. This spatial reconfiguration in a different dimensional arrangement (circular/annular pattern) allows the nozzles to spray cleaning agent onto the camera cover from multiple angles around the periphery, maintaining comprehensive cleaning coverage while keeping the nozzles positioned away from the direct optical path of the camera lens, thus preserving the field of view.
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
The system provides a compact, effective cleaning solution that optimizes cleaning efficiency and field of view by adjusting parameters like water pressure, spray time, and deflector placement, reducing visual impairment and allowing installation in confined spaces.
Implementation Method 1
at least two cleaning agent spraying elements which are arranged in a cleaning agent spraying portion which is connected to the cleaning agent feed line, for distributing the cleaning agent on the cover to be cleaned
