Elastomeric Seal Ring for Pressurized Liquid Transfusion Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosolizers face challenges in maintaining a proper seal between miniature components, leading to pressure loss and imprecise dosage delivery due to their small size and high-pressure environment, which complicates manufacturing and assembly, and reduces the device's lifespan.
Innovation Solution
The aerosolizer design incorporates an elastomeric ring and nozzle combination within a receptacle covered by a cap, secured by a check nut, with specific surface treatments and dimensions to ensure a watertight or airtight seal, reducing leakage and corrosion, and enhancing adherence between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing methods are used in miniature aerosolizer components, then manufacturing precision can be maintained, but pressure loss and leakage occur due to difficulty in achieving proper seal
Solution Approach 1:
The patent employs an elastomeric seal ring (thin film) that flexes to conform to the nozzle opening, creating a reliable seal without requiring high manufacturing precision. The elastic material compensates for dimensional variations and assembly tolerances, preventing pressure loss and leakage in the miniature component environment.
2Volume of moving object
If components are made miniature to reduce device size, then portability is improved, but sealing becomes more difficult and costly
Solution Approach 1:
The elastomeric seal ring provides a simple, cost-effective sealing solution for miniature components. Its flexibility allows it to adapt to small variations in component dimensions, eliminating the need for complex sealing mechanisms that would increase manufacturing difficulty and cost in miniature scale.
3Power
If high pressure is applied for aerosolization, then aerosol generation is improved, but component wear and corrosion increase
Solution Approach 1:
The elastomeric seal ring creates a tight seal that prevents liquid medicament from penetrating between components. This containment reduces corrosion and wear on internal parts, extending device lifespan while maintaining the high pressure needed for effective aerosolization.
Solution Approach 2:
The seal ring is designed as a replaceable, inexpensive component that can be easily replaced when worn. This allows the main device body to have extended lifespan while the consumable seal ring absorbs the wear from high-pressure operation.

Data Source
AI summary
An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.
