Multi-compartment Make-up Product with Segmented Sponges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic products in fluid or semi-liquid form are inconvenient to apply without waste, and existing solutions with sponges still face issues with product migration and uneven application.
Innovation Solution
A multi-colour make-up product container with at least two distinct fluid make-up products, each with a sponge, where the sponges are coated to prevent fluid migration and are constrained within the container to minimize waste and ensure even application, using a formula with low dynamic viscosity to optimize absorption and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fluid make-up products are placed in the same container with multiple sponges, then product variety and usability are improved, but product migration between sponges occurs causing uneven application
Solution Approach 1:
The container is divided into separate compartments, each housing a distinct sponge soaked with a specific make-up product. This segmentation prevents fluid migration between different products while maintaining multiple product varieties in one container, directly resolving the contradiction between versatility and application evenness.
Solution Approach 2:
A partition wall acts as an intermediary barrier between different sponges and their respective fluids. This physical separator prevents unwanted fluid migration while allowing each sponge to maintain its intended product concentration and properties, ensuring reliable application for each make-up type.
2Ease of operation
If sponges are used to apply fluid make-up products, then ease of application is improved, but product waste increases
Solution Approach 1:
Each sponge is sized and formulated to provide the exact amount of product needed for application, avoiding the need to use excess product that would occur with traditional fluid application methods. The sponge absorbs and releases product in controlled amounts, reducing waste while maintaining ease of application.
Solution Approach 2:
The sponges are pre-soaked with the appropriate amount of make-up product during manufacturing, eliminating the need for users to manually dispense and control fluid products. This self-contained approach ensures consistent product distribution and minimizes waste from over-application or spillage.
3Manufacturing precision
If sponges are constrained within the container, then product distribution uniformity is improved, but device complexity increases
Solution Approach 1:
The container uses simple compartmental segmentation to constrain each sponge in its designated space. This straightforward structural division ensures uniform product distribution by preventing sponge movement and fluid mixing, while adding minimal complexity to the overall device design.
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 solution allows for improved usability and reduced waste by preventing fluid migration between sponges, ensuring consistent product distribution and minimizing application issues such as unevenness and line formation, while maintaining the quality of the cosmetic product.
Implementation Method 1
a first sponge (3A) soaked with a first make-up fluid (3B)
Implementation Method 2
The formula with which the make-up fluid 3B, 4B is made has a low dynamic viscosity, such as between 1000 and 10,000 cPs. It is designed not to create differences in the amount of product contained in the sponge
