Multi-aperture Diffuser for Uniform Hair Aerosol Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol sprays for hair styling are not ideal for localized application, leading to inefficient use of fixing and styling agents and unsatisfactory hair style maintenance over time.
Innovation Solution
An aerosol device with a diffuser having at least three spraying apertures is used to distribute a composition containing fixing polymers and water-insoluble inorganic compounds, allowing for uniform application and effective hair styling with reduced agent usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional aerosol spray is used for hair styling, then the fixing and styling agents can be applied to the hair, but the application is not localized and the agents are not distributed uniformly
Solution Approach 1:
The single spray aperture is divided into multiple apertures (at least two, preferably three or more) within the diffuser. This segmentation allows the aerosol composition to be distributed into multiple separate streams, achieving both localized application capability and uniform distribution across the targeted hair area. Each aperture acts as an independent delivery point, enabling precise control over where the styling agents are applied.
2Quantity of substance
If a conventional aerosol spray is used, then hair styling can be achieved, but the amount of fixing and styling agents used is excessive
Solution Approach 1:
The diffuser with multiple apertures enables localized delivery of the aerosol composition directly to the specific areas of hair that need styling. This localized quality approach ensures that the fixing and styling agents are applied only where needed, rather than being dispersed unnecessarily across the entire hair mass. The result is reduced consumption of styling agents while maintaining effective style fixation in the targeted areas.
3Duration of action of stationary object
If a conventional aerosol spray is used, then hair styling can be achieved, but the style maintenance over time is insufficient
Solution Approach 1:
The diffuser design with multiple apertures creates a dynamic distribution pattern that adapts to the hair structure and styling needs. The aerosol composition is delivered through multiple pathways simultaneously, creating a more comprehensive and durable fixation network throughout the hair. This dynamic multi-aperture approach enhances both the immediate shaping effect and the long-term style maintenance, making the styling process more efficient and effective.
