Ultrasonic Fragrance Atomiser Wick and Carrier Solvent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasonic atomizers face inefficiencies due to poorly aligned interfaces between vibrating plates and liquid fragrance sources, leading to inconsistent fragrance release and spray formation issues, with high delivery rates causing incomplete atomization and low rates resulting in poor fragrance distribution.
Innovation Solution
The use of high concentrations of branched or iso-alkanes as carrier solvents in fragrance compositions, specifically between 50% and 98% by weight, along with a polypropylene wick and controlled activation settings, enhances atomization efficiency and reduces residues, while the refill system with a wick prevents clogging and allows for easy fragrance changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high delivery rate of liquid fragrance is used, then fragrance release rate is improved, but spray formation and incomplete atomization occur
Solution Approach 1:
The patent changes the chemical composition parameters of the carrier liquid by incorporating specific surfactants and co-solvents that modify surface tension and volatility characteristics, enabling the liquid to atomize properly at higher delivery rates without forming spray or residues
Solution Approach 2:
The patent introduces surfactants as intermediary substances that mediate between the liquid fragrance and the vibrating plate interface, improving wetting properties and ensuring consistent liquid transfer at higher rates while maintaining complete atomization
2Reliability
If low delivery rate of liquid fragrance is used, then complete atomization is achieved, but fragrance distribution is poor
Solution Approach 1:
The patent modifies the physical parameters of the carrier liquid through surfactant addition, which enhances atomization efficiency and allows the system to achieve complete atomization at higher delivery rates, thereby improving fragrance distribution without compromising atomization quality
3Ease of operation
If conventional carrier liquids are used, then device operation is simple, but residues and particle drop out occur
Solution Approach 1:
The patent changes the chemical composition of the carrier liquid by incorporating specific surfactants and co-solvents that reduce surface tension and improve volatility, resulting in complete atomization without residues or particle drop out while maintaining ease of device operation
Solution Approach 2:
The patent creates a composite carrier liquid system combining surfactants, co-solvents, and fragrance compounds that work synergistically to prevent residue formation and particle drop out, improving overall atomization performance without complicating device operation

Implementation Method 1
They usually comprise a vibrating plate... The contact between the piezo vibrating plate and the source of the liquid fragrance must be in finely balanced to allow for successful operation.
Implementation Method 2
a means to transport the liquid fragrance to the plate for atomisation... The liquid transport member moves liquid from the reservoir to the plate by wicking or capillary action.
