Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray devices face challenges in effectively atomizing fluids at high pressures while maintaining durability and cleaning internal components, as high-pressure water systems are prone to wear and blockages.
Innovation Solution
A nozzle assembly with a base body and inserter, where a first fluid is discharged through a lower-pressure supply line and a second fluid with a higher pressure is introduced through a guide groove, creating a swirling force to atomize the first fluid and facilitate internal cleaning by reversing flow direction for foreign substance removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-pressure water is supplied to the spray pipe to increase atomization effect, then the atomization of water is improved, but the durability of parts deteriorates due to high-pressure wear
Solution Approach 1:
The spray system is divided into multiple nozzles, each operating at lower pressure individually, rather than one high-pressure nozzle. This segmentation allows the atomization function to be distributed across multiple lower-pressure outlets, reducing wear on each component while maintaining overall atomization effectiveness.
Solution Approach 2:
The patent employs a nested structure where multiple nozzles are integrated into a common spray pipe system. The lower-pressure nozzles are nested within the overall high-flow system, allowing each nozzle to operate independently at optimized lower pressures while contributing to the collective atomization performance.
2Manufacturing precision
If high-pressure water is used to spray through nozzles, then the atomization effect is enhanced, but the system becomes more susceptible to blockages and wear
Solution Approach 1:
By segmenting the spray function into multiple nozzles operating at lower pressures, the system reduces the harmful effects of high pressure on each individual nozzle, minimizing wear and blockage susceptibility while preserving atomization quality.
Solution Approach 2:
The patent changes the pressure parameter from high to lower pressure across multiple nozzles, and adjusts the flow distribution parameters to achieve effective atomization without the detrimental effects of high pressure on nozzle durability and blockage resistance.
3Device complexity
If a single high-pressure nozzle is used, then the system structure is simple, but the atomization effect is insufficient and durability is reduced
Solution Approach 1:
The spray function is segmented into multiple nozzles along the spray pipe, where each nozzle contributes to the overall atomization effect. This segmentation improves atomization quality compared to a single nozzle while keeping the overall structure relatively simple through the integrated pipe design.
Solution Approach 2:
The spray pipe serves multiple functions: it acts as both the structural conduit for water flow and as the mounting structure for multiple nozzles. This multi-functionality allows the system to achieve improved atomization through multiple outlets while maintaining structural simplicity through the integrated pipe design.
4Area of stationary object
If multiple nozzles are connected to the spray pipe to improve atomization, then the spray coverage is increased, but the system complexity and pressure requirements increase
Solution Approach 1:
The spray pipe is designed to serve multiple functions simultaneously: it provides structural support, conducts water flow, and mounts multiple nozzles. This multi-functionality allows the system to achieve wide spray coverage through multiple nozzles while minimizing additional complexity by using the existing pipe structure for multiple purposes.
Solution Approach 2:
The spray coverage area is segmented into multiple zones, each served by an individual nozzle at lower pressure. This segmentation achieves wide overall coverage while keeping each nozzle simple and operating at manageable pressure levels, reducing system complexity compared to a single high-pressure system.
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 nozzle assembly efficiently atomizes fluids into small particles, ensures wide-area coverage, and effectively cleans the system by using the higher-pressure second fluid to break apart and remove blockages, maintaining system integrity and functionality.
Implementation Method 1
a second fluid with a higher pressure is introduced into the nozzle assembly through the guide groove, the second fluid forming a vortex, and thus, the first fluid is sprayed more finely
Implementation Method 2
the first fluid is sprayed more finely due to the collision with the second fluid having a swirling force
Implementation Method 3
When the end of the nozzle assembly is blocked, the flow direction of the second fluid is changed, and thus, the second fluid moves in a direction opposite to the moving direction of the first fluid
