Cosmetic Container With Brushing Device For Direct Perfume Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers waste perfume as the spray range is large, with only a portion being applied to the user's skin, while the rest is sprayed into the air, leading to inefficient use and potential damage to surrounding items.
Innovation Solution
A cosmetic container design featuring a shell, pressing member, containing device, brushing device with bristles, and cap, where the perfume is drawn into the bristles for direct application to the skin, minimizing air spray and allowing adjustable fragrance dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If perfume is sprayed in spraying form, then the spray range is large, but most of the perfume is wasted and not applied to the user's skin
Solution Approach 1:
The patent introduces a brush as an intermediary carrier between the perfume liquid and the user's skin. The brush absorbs and holds the perfume liquid, then transfers it directly to the skin through brushing motion. This intermediary approach prevents the perfume from being sprayed into the air and ensures direct application to the target area, significantly reducing waste.
Solution Approach 2:
The patent replaces the conventional spray mechanism (aerosol generation) with a mechanical brushing system. Instead of using pressure to atomize the perfume into fine droplets that disperse in air, the system uses a brush to mechanically transfer the liquid perfume directly to the skin. This substitution eliminates the harmful dispersion effect and improves application precision.
2Quantity of substance
If conventional spray device is used, then the perfume can be dispersed widely, but the perfume cannot be completely sprayed on the skin of the user
Solution Approach 1:
The brush serves as a controlled intermediary that holds a specific amount of perfume liquid on its bristles. This allows precise control over the quantity of perfume applied - the brush can be pressed against the skin to transfer the exact amount needed, preventing both over-application and waste. The intermediary brush creates a controlled transfer mechanism rather than uncontrolled spray dispersion.
3Productivity
If spray head is pressed to withdraw perfume, then the perfume is nebulized out of the spray opening, but the spray range is large and causes waste
Solution Approach 1:
The patent replaces the pneumatic spray mechanism (pressurized nebulization) with a mechanical transfer system using a brush. The brush is pressed against the perfume reservoir to absorb the liquid, then pressed against the skin to transfer it. This mechanical substitution eliminates the need for high-pressure atomization and prevents the perfume from being dispersed into the air, maintaining productivity while eliminating waste.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures that perfume is efficiently applied to the skin, reducing waste and preventing damage to clothing or jewelry, while allowing for customizable fragrance application.
Implementation Method 1
The liquid fragrance passes through the spray head and is sprayed into the inlet for moistening the bristles
