Linearly Movable Spray Nozzle for Vehicle Camera Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cleaning devices with spray nozzles face challenges in effectively cleaning curved surfaces and have high wear on components due to direct pressure on check valves, leading to reduced durability and efficiency.
Innovation Solution
A cleaning device with a linearly movable, extendable spray nozzle unit that is connected to a liquid supply source, where the pressure of the cleaning liquid indirectly acts on a check valve, allowing for adjustable angle dispensing and reduced stress on components, enabling effective cleaning of vehicle cameras and lenses with increased device lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning liquid pressure acts directly on the check valve, then the cleaning liquid can be supplied effectively, but the wear on the check valve increases leading to reduced durability
Solution Approach 1:
A movable spray nozzle unit is introduced as an intermediary between the cleaning liquid supply and the check valve. The spray nozzle unit absorbs the pressure of the cleaning liquid and translates it into mechanical movement, preventing direct pressure transmission to the check valve and thereby reducing wear while maintaining effective cleaning liquid supply
2Ease of manufacture
If the spray nozzle is fixed, then the device structure is simple, but the cleaning liquid cannot be supplied effectively to curved surfaces
Solution Approach 1:
The spray nozzle is transformed from a fixed structure to a dynamically movable one. The spray nozzle unit can extend and retract linearly, allowing it to adapt its position and angle relative to curved surfaces during operation, thereby improving cleaning effectiveness while maintaining relatively simple structural design
3Productivity
If the spray nozzle unit is extended for cleaning, then the cleaning angle is improved, but the device complexity increases
Solution Approach 1:
The spray nozzle system is segmented into a movable spray nozzle unit and a stationary housing. This segmentation allows the spray nozzle unit to be independently extended or retracted to achieve optimal cleaning angles, while the housing remains simple and stationary, thereby improving cleaning capability without significantly increasing overall device complexity

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 device effectively cleans vehicle cameras and lenses by allowing for adjustable angle dispensing and reduced wear on components, extending the device's operational period and simplifying the cleaning process without the need for manual or motorized adjustments.
Implementation Method 1
the spray nozzle unit being able to be moved by means of pressure of the cleaning liquid when the cleaning liquid is supplied
Implementation Method 2
the pressure of the cleaning liquid acts indirectly on a check valve of the cleaning device for passing on the cleaning liquid
