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

VSEngineering 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

Engineering Contradiction:
Improveproduct varietyVSAvoidapplication evenness
Core Design Contradiction:
Adaptability or versatilityVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If sponges are used to apply fluid make-up products, then ease of application is improved, but product waste increases

Engineering Contradiction:
Improveapplication easeVSAvoidproduct waste
Core Design Contradiction:
Ease of operationVSLoss of substance

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.

Inventive Principle:
Principle #16Partial or excessive action

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.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If sponges are constrained within the container, then product distribution uniformity is improved, but device complexity increases

Engineering Contradiction:
Improveproduct distribution uniformityVSAvoidcontainer structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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)

Methodology Applied
Scientific EffectAbsorption: Absorption (physical)

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

Methodology Applied
Scientific EffectCapillary action: Capillary Action
