Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmittable kinetic energy and cleaning power of liquid jets from flat jet nozzles decrease with increasing distance from the surface to be cleaned, especially in dense or viscous media, and existing solutions like using more powerful compressors are economically and technically limited.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If more powerful compressors are used to increase kinetic energy, then cleaning power is improved, but economic and technical limitations are increased
Solution Approach 1:
A gas inlet opening is introduced as an intermediary element that allows gas to enter the expansion zone. This gas acts as a mediator between the liquid jet and the surrounding medium, forming a gas curtain that preserves the liquid jet's geometry and prevents dispersion, thereby enhancing cleaning power without requiring more powerful compressors
Solution Approach 2:
The invention utilizes pneumatic principles by introducing gas into the expansion zone through the gas inlet opening. The gas forms a gas curtain that hydraulically supports the liquid jet, maintaining its shape and direction. This pneumatic-hydraulic interaction enables enhanced cleaning power through fluid dynamics rather than increased compressor power
2Adaptability or versatility
If the liquid jet is used in dense or viscous media, then cleaning application is improved, but kinetic energy transmission is reduced
Solution Approach 1:
The gas inlet opening serves as an intermediary that introduces gas into the expansion zone. This gas acts as a buffer between the liquid jet and the dense/viscous surrounding medium, forming a gas curtain that protects the liquid jet from rapid dispersion and maintains its kinetic energy transmission capability in challenging media conditions
Solution Approach 2:
The invention changes the physical parameters of the expansion zone by introducing gas, which alters the density and viscosity characteristics within the expansion zone. This parameter change enables the liquid jet to maintain its energy transmission properties when operating in dense or viscous media
3Speed
If the liquid jet exits the nozzle at high speed, then cleaning effect is improved, but jet dispersion increases with distance
Solution Approach 1:
The gas inlet opening introduces gas as an intermediary substance that forms a gas curtain around the liquid jet. This gas curtain acts as a protective boundary that maintains the liquid jet's geometry and prevents dispersion over distance, allowing high-speed jet exit while preserving jet stability
Solution Approach 2:
The system utilizes pneumatic principles to create a gas curtain that hydraulically supports the liquid jet. This gas-liquid interaction maintains the jet's shape and directionality, enabling high-speed exit while preventing dispersion through pneumatic-hydraulic coupling
