Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure liquid projection nozzles have fixed geometries, leading to increased cycle time and inefficiency in industrial operations due to the need for nozzle switching between different applications, excessive cleaning solution consumption, and environmental concerns from over-flooding.
Innovation Solution
A high-pressure liquid projection assembly with a variable spray pattern is achieved through a nozzle housing with a venturi, fluid chamber, and control port connected to a variable flow pressurized liquid source, allowing for adjustment of the liquid projection pattern via a valve, enabling a single nozzle to perform multiple operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed geometry nozzles are used for different applications, then each application requires a dedicated nozzle, but this increases cycle time and operational complexity due to nozzle switching
Solution Approach 1:
The nozzle is designed with a fixed geometry internal structure that can perform multiple functions (deburring, cleaning, washing) by adjusting operational parameters such as liquid flow rate and pressure, eliminating the need for physical nozzle changes between different applications
Solution Approach 2:
The nozzle incorporates adjustable parameters including variable liquid flow rate control and movable components that allow dynamic adaptation to different applications while maintaining a fixed geometric structure, enabling a single nozzle to replace multiple fixed-geometry nozzles
2Adaptability or versatility
If fixed geometry nozzles are used for different applications, then each application requires a dedicated nozzle, but this increases device complexity due to multiple nozzles and fluid couplings
Solution Approach 1:
A single fixed geometry nozzle design is capable of performing multiple applications (deburring, cleaning, washing) through parameter adjustment, eliminating the need for multiple specialized nozzles and the complex fluid coupling mechanisms required for switching between them
3Ease of operation
If steady state liquid projection is used during cleaning operation, then the cleaning operation is simple, but excessive cleaning solution is consumed and the part is over-flooded reducing efficiency
Solution Approach 1:
The cleaning operation uses dynamically adjustable liquid flow rates rather than steady state projection, allowing the system to optimize solution usage by matching the flow rate to the specific cleaning requirements, thereby preventing over-flooding and reducing cleaning solution consumption while maintaining operational simplicity
Solution Approach 2:
The system changes operational parameters including liquid flow rate and pressure to optimize cleaning efficiency, allowing variable control over the liquid projection to prevent excessive solution consumption and part over-flooding while maintaining ease of operation

AI summary
A high-pressure liquid projection assembly for cleaning and/or deburring industrial parts, having a housing with an inlet adapted for connection with a pressurized liquid source, an outlet and a fluid passageway connecting the inlet to the outlet. A fluid chamber is formed in the housing and disposed around an intermediate portion of the passageway. At least one opening is formed in the housing which fluidly connects the chamber to the passageway while a control port on the housing is fluidly connected to the chamber. The control port is adapted to be connected to a variable flow pressurized liquid source to thereby vary the projection cone pattern from the outlet as a function of the valve opening.
