Atomizing Body Outflow Port Intersection Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing devices face issues with manufacturing tolerances affecting the reproducibility and performance due to irregularities in the edge of the atomizing body and potential contamination, leading to asymmetry and blockages in the outflow ports, which impact the vaporizing pattern and efficiency.
Innovation Solution
The atomizing device design positions the intersection of the outflow ports' central axes outside the vaporizing space, allowing for precise manufacturing and minimizing the influence of edge variations, with outflow ports formed on substrates that protrude beyond the vaporizing space, reducing obstruction and enabling standard separation techniques, and using high-precision techniques for precise structure creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the atomizing body is released by cleaving, cutting or sawing during manufacture, then the device can be produced, but irregularities in the edge of the body and contamination of the passage system occur, resulting in blockage and loss
Solution Approach 1:
The outflow ports are extracted from the edge of the atomizing body and positioned on the main surface, away from the separation zone. This extraction eliminates the problem of edge irregularities and contamination from cleaving, cutting or sawing processes, while maintaining the functionality of the outflow ports.
Solution Approach 2:
The outflow ports are formed on the main surface of the atomizing body before the separation process. This preliminary positioning ensures that the passage system is not contaminated during manufacturing, preventing blockage and loss while allowing standard separation techniques to be used.
2Device complexity
If the outflow ports are positioned close to the edge of the atomizing body, then the device structure is compact, but manufacturing tolerances cause asymmetry and variations in the vaporizing pattern
Solution Approach 1:
A distance element is introduced between the outflow ports and the edge of the atomizing body. This intermediary distance acts as a buffer that isolates the outflow ports from edge variations and manufacturing tolerances, ensuring consistent vaporizing patterns while allowing for standard manufacturing processes.
3Manufacturing precision
If high-precision techniques are used for structure creation, then manufacturing precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The outflow ports are formed using standard separation techniques that create consistent, repeatable structures. By positioning the outflow ports away from the separation zone and using established manufacturing methods, the need for complex high-precision techniques is eliminated while maintaining manufacturing precision.

Function Achieved in This Case
This design enhances reproducibility and reduces operational fluctuations, allowing for precise control over the vaporizing pattern and minimizing contamination, resulting in a more reliable and efficient atomizing device with reduced manufacturing complexity and cost.
Implementation Method 1
A set of liquid jets making said angle relative to each other and meeting at an intersection outside the body are thus formed on the delivery side. As a result of the collision of the two liquid jets they divide into small droplets at and close to the intersection and thus form a vapour. This process is also referred to as the 'impinging jet' principle

AI summary
An atomizing device, comprising an atomizing body (1) with an inlet (16) for receiving a fluid under increased pressure, and with at least one set of outflow ports (18) for allowing the fluid to escape on a delivery side with forming of a vapour. Imaginary central axes of the outflow ports directed in a flow direction herein enclose a mutual angle ( ) in order to intersect each other at an intersection (S). The atomizing body comprises a roof (21) and a bottom (11) which extend over at least a first distance (d1) beyond the set of outflow ports (18) and bound a vaporizing space (17) on either side. The intersection (S) of the imaginary central axes of the outflow ports lies at a second distance (d2) from the set of outflow ports, wherein the second distance (d2) is greater than the first distance (d1) and extends beyond the vaporizing space (17). In a further aspect of the invention the atomizing body is able and adapted to capture supplied radiation, thus forming heat. In a further aspect the atomizing body is in an envelope which at least on a boundary layer is adhered with a boundary layer to the atomizing body.
