Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product packaging technologies fail to efficiently mix and homogenize two-phase cosmetic products, leading to complexity and inefficiency in compactness and user experience.
Innovation Solution
A pair of disposable deformable capsules with a breakable wall separating the phases, allowing for simple and homogeneous heating and mechanical expulsion of contents, using a multilayer thermoformed shell and polyolefin polymer for robustness and ease of manufacture, with a communication channel for efficient mixing and homogenization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a capsule contains two phases separated by a frangible partition, then the phases can be preserved separately during storage, but the mixing and homogenization complexity increases
Solution Approach 1:
The capsule is divided into two separate compartments by a frangible partition, with each compartment containing one phase of the cosmetic product. This segmentation allows independent preservation of phases during storage while enabling simple mixing when needed.
Solution Approach 2:
The frangible partition is designed to be easily removed or broken, extracting the barrier between phases and allowing direct contact and mixing of the two phases without complex mixing mechanisms.
2Ease of operation
If the pouch has a curved and flexible surface, then mechanical expulsion of contents becomes easier, but heating homogeneity becomes more difficult
Solution Approach 1:
The pouch is designed with a flat surface specifically at the heating zone to ensure uniform heat distribution, while maintaining curved and flexible surfaces in other areas to facilitate easy mechanical expulsion of contents.
3Ease of manufacture
If the capsule structure is simplified, then manufacturing becomes easier, but the compactness of the mixing machine increases
Solution Approach 1:
The capsule design integrates multiple functions into a single structure: the pouch contains the phases, the frangible partition enables phase separation, and the communication channel facilitates mixing. This merging reduces the need for separate mixing components, thereby simplifying the overall manufacturing process while maintaining compact mixing chamber dimensions.

AI summary
The invention relates to a single-use deformable capsule comprising: a compartment (11, 21) containing a predetermined quantity of only one of the two phases, the mixing of which forms a cosmetic product ready for use, a channel-shaped constriction (13, 23) leading, on one side, into the compartment (11, 12 and 21, 22) and, on the other side, to the outside of the capsule (1, 2), the compartment (11, 12 and 21, 22) being flattened, one (17) of its two faces being planar, the other (16) of its two faces being at least partially convex and flexible so that the contents of the compartment (11, 12 and 21, 22) can be expelled by mechanical pressure thereon.
