Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-liquid mixing-type aerosol products face challenges in achieving high storage stability and forming highly viscous discharge materials with high functionality, particularly when combining formulations with different properties, such as water-based and oil-based cosmetic compositions, which often result in restricted formulation design and stability issues.
Innovation Solution
A double-structure container with a propellant filling space and two independent liquid concentrate filling spaces, where the first liquid concentrate composition is water-based and the second is oil-based, both with viscosities between 1,000 to 125,000 mPa·s, allows for simultaneous discharge with a controlled mixing ratio, ensuring high formulation stability and long-term storage without exposure to air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two highly viscous liquid cosmetic formulations are mixed in advance, then formulation design freedom is increased, but storage stability deteriorates due to exposure to air and restricted formulation design
Solution Approach 1:
The container is divided into two separate filling spaces, each containing a different liquid concentrate composition (water-based and oil-based). This segmentation allows each composition to maintain its own formulation stability while enabling design freedom through the combination of different types of compositions that would be incompatible if mixed in advance.
Solution Approach 2:
Both liquid concentrate compositions are prepared and filled into the container in advance, but kept separate in their respective filling spaces. The compositions are pre-formulated with high viscosity (1,000 to 125,000 mPa·s) to ensure stability during storage, and the mixing action is postponed until the moment of use through the simultaneous discharge mechanism.
2Reliability
If two highly viscous liquid cosmetic formulations are stored separately in hermetically sealed containers, then storage stability is maintained, but the mixing process becomes burdensome
Solution Approach 1:
Two separate hermetically sealed containers are merged into a single double-structure container with two independent filling spaces. This merging maintains the storage stability benefits of separate containment while eliminating the need for manual mixing operations, as the discharging mechanism automatically mixes the compositions simultaneously during dispensing.
Solution Approach 2:
The system performs the mixing function automatically through its discharging mechanism, which simultaneously discharges both liquid concentrate compositions in a controlled mixing ratio. The user simply operates the dispenser, and the system handles the mixing process itself without requiring manual intervention, making the operation simple while maintaining storage stability.
3Manufacturing precision
If two liquid cosmetic formulations are discharged simultaneously with controlled mixing ratio, then consistent discharge ratios are achieved, but device complexity increases
Solution Approach 1:
The viscosity of both liquid concentrate compositions is controlled within a specific range (1,000 to 125,000 mPa·s). By standardizing this critical parameter, the discharge rates of both compositions become predictable and consistent, achieving reliable mixing ratios without requiring complex control mechanisms. The propellant composition and pressure are also standardized to ensure consistent discharge behavior.
