Nozzle Unit with Vortex Chambers for Pharmaceutical Dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for pharmaceutical media fail to achieve a satisfactory atomized discharge, especially when multiple nozzles are used, due to complex and costly structures that do not produce a high-quality spray jet.
Innovation Solution
A nozzle unit with distinct vortex chambers for each discharge nozzle, connected upstream to the common supply channel, imparts a twist to the medium, allowing for improved atomization and a better spray pattern, utilizing a basic and top component design for cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple discharge orifices are directly connected to a common supply channel, then the dispenser can discharge pharmaceutical medium through multiple nozzles simultaneously, but the medium is discharged in a largely non-atomized condition
Solution Approach 1:
The invention divides the common supply channel into multiple separate supply channels, each leading to its own vortex chamber and discharge orifice. This segmentation allows each nozzle to receive independently controlled medium flow, enabling proper atomization at each discharge point while maintaining multi-nozzle simultaneous operation capability.
Solution Approach 2:
The invention introduces vortex chambers as intermediary components between the supply channel and discharge orifices. These vortex chambers impart rotational motion to the medium before discharge, transforming the non-atomized flow into an atomized spray pattern, thus mediating between the supply system and the discharge requirement.
2Manufacturing precision
If a common vortex chamber is connected upstream of multiple discharge orifices, then atomization can be achieved, but the structure becomes complex and laborious to produce
Solution Approach 1:
Instead of using a single common vortex chamber, the invention segments the vortex chamber function into multiple separate vortex chambers, each associated with one discharge orifice. This segmentation simplifies the overall structure by allowing each vortex chamber to be independently designed and manufactured, reducing complexity while maintaining atomization quality.
Solution Approach 2:
The invention combines multiple simple vortex chamber units into a single integrated nozzle unit assembly. While each vortex chamber is simple and easy to produce, their combination within the unified dispenser structure achieves both atomization quality and manufacturing simplicity, avoiding the complexity of a single large common vortex chamber.
3Manufacturing precision
If each discharge nozzle has its own vortex chamber, then high-quality atomized spray jets can be delivered, but manufacturing costs increase
Solution Approach 1:
The invention segments the atomization function into multiple identical or similar vortex chamber units, each serving one discharge nozzle. This segmentation allows for standardized manufacturing of each unit, which can be produced using the same tooling and processes, thereby reducing per-unit manufacturing costs despite having multiple chambers.
Solution Approach 2:
The invention maintains consistent geometric parameters and design specifications across all vortex chambers in the nozzle unit. By standardizing the vortex chamber dimensions, inlet configurations, and outlet orientations, the manufacturing process becomes repetitive and efficient, reducing overall manufacturing costs while ensuring consistent spray jet quality across all nozzles.
