Nebulizing Device for Deep Skin Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for delivering substances with active principles, such as those used in cosmetic and pharmaceutical applications, face issues with high viscosity leading to ineffective penetration and application, including incorrect dosage, non-penetration, drying, and loss of product, especially when trying to treat deep skin layers or sensitive areas without direct hand contact.
Innovation Solution
A portable, compact device with a nebulizing system using a piezoelectric or ultrasound actuator and delivery apertures of 10 micrometers or less, allowing for precise delivery of liquid-based substances with adjustable viscosity to penetrate deep layers effectively and apply active principles to specific zones without hand contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If substances with high viscosity are used to treat skin problems, then the substance can be spread directly on the affected zone, but the substance does not penetrate effectively into deep layers of the skin
Solution Approach 1:
The patent changes the physical state and size parameters of the substance by nebulizing it into fine particles with diameters between 1-10 micrometers. This parameter change allows the substance to penetrate deep skin layers effectively while maintaining the active ingredients' therapeutic properties
Solution Approach 2:
The patent employs ultrasonic vibration (mechanical vibration at high frequency) to atomize the liquid substance into fine nebulized particles. This mechanical vibration mechanism enables the substance to be delivered in a form that can penetrate deep skin layers without requiring direct hand contact
2Ease of operation
If substances are diluted and applied via spray diffusers, then the substance can be distributed, but the drop sizes are too large to penetrate effectively into the surface
Solution Approach 1:
The patent uses ultrasonic vibration to atomize the diluted substance into fine particles with diameters of 1-10 micrometers, much smaller than conventional spray drops. This enables effective penetration into skin surfaces while maintaining easy distribution
Solution Approach 2:
The patent changes the size parameter of the substance from large spray drops to fine nebulized particles through ultrasonic atomization. This parameter change achieves both effective distribution and deep penetration capability
3Quantity of substance
If creams are applied to the scalp for trichological treatments, then the active principles can be delivered, but the creams are very obvious on the root of the hair
Solution Approach 1:
The patent changes the physical form parameter from visible cream to invisible nebulized particles. The fine particle size (1-10 micrometers) allows the substance to be absorbed quickly without leaving visible residue on hair roots, eliminating the cosmetic defect
4Ease of operation
If substances are applied by spreading on the surface, then the substance can be delivered, but the product largely remains on the palm of the hand causing loss
Solution Approach 1:
The patent replaces the manual spreading mechanical action with an automated nebulization system that delivers the substance directly to the target area as fine particles. This substitution eliminates the need for hand contact and spreading, preventing product loss on the palm
5Ease of operation
If substances are applied with jets and sprays from diffusers, then the substance can be distributed, but the application does not allow great depths of penetration into the part where the drops are distributed
Solution Approach 1:
The patent uses ultrasonic vibration to create fine nebulized particles instead of large spray drops. This mechanical vibration-based atomization enables the distributed substance to penetrate deep into skin layers, overcoming the limitation of conventional spray diffusers
