Solution Overview

Problem

Many cosmetic compositions, such as long-wearing lip and foundation products, face challenges in achieving both good application properties and long-wear/transfer-resistance while often requiring multiple applications due to immiscible components that separate after application, leading to poor feel and appearance issues.

Innovation Solution

A multi-phase cosmetic composition mixing pack with a container and a mixing element, such as a coil spring or perforated plunger, that temporarily mixes immiscible components within the container, allowing for a single-step application that forms a multilayer structure on the skin or lips, improving wear, feel, and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If immiscible components are used to achieve long-wear and transfer-resistance, then durability is improved, but application properties and uniformity deteriorate due to component separation

Engineering Contradiction:

Improvelong-wear and transfer-resistanceVSAvoidcomponent separation

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by providing instructions to consumers to shake or vortex the product before application. This pre-mixing action temporarily combines the immiscible components (water-soluble and oil-soluble phases) into a uniform mixture that can be applied in a single step, ensuring both long-wear properties and good application characteristics without requiring the components to remain permanently miscible

Inventive Principle:

Principle #10Preliminary action

2Quantity of substance

If multiple applications are used to achieve complete coverage, then coverage is improved, but time consumption and frequency of reapplication increase

Engineering Contradiction:

ImprovecoverageVSAvoidtime for reapplication

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent combines multiple components into a single multi-phase composition that, when shaken or vortexed before application, provides complete coverage in one application. This eliminates the need for multiple separate applications and reduces reapplication frequency, saving time while maintaining full coverage

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent merges water-soluble components and oil-soluble components into a single multi-phase cosmetic composition. This unified composition can be applied in one step to achieve complete coverage, eliminating the need for separate applications of different product layers

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If immiscible components separate after application, then long-wear properties are achieved, but feel and appearance properties deteriorate

Engineering Contradiction:

Improvelong-wear propertiesVSAvoidpoor feel and appearance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by instructing users to shake or vortex the product before application, creating a temporary uniform mixture that provides good feel and appearance upon application. The immiscible components separate after application to maintain long-wear properties, but the preliminary mixing ensures the application phase delivers desirable sensory and visual characteristics

Inventive Principle:

Principle #10Preliminary action

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 mixing pack ensures that immiscible components are temporarily miscible, enhancing the cosmetic properties of the composition by allowing for a single-step application that maintains long-wear and transfer-resistance without the need for constant reapplication, improving user experience and product acceptance.

AI summary

A multi-phase cosmetic composition mixing pack for mixing immiscible components of a multi-phase cosmetic composition such that they are temporarily miscible includes a container for holding the multi-phase cosmetic composition that has a first open end and a container longitudinal axis, and a mixing element disposed within the container and configured to be actuated for mixing immiscible components of the multi-phase cosmetic composition such that they are temporarily miscible, wherein the mixing element is limited to movement substantially along the container longitudinal axis when actuated.
