Solution Overview

Problem

Conventional methods for applying cosmetic substances lack precision in delivering active ingredients to the deeper layers of the skin, often resulting in lower efficacy and wastage due to imprecise application and exposure to ambient conditions that affect product stability.

Innovation Solution

A handheld device with a biasing mechanism and applicator tip that allows controlled delivery of cosmetic substances to a depth of 10-45 μm into the epidermal layer, featuring a feedback indicator for optimal force application and an applicator tip with microstructures like microneedles to ensure targeted delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional methods are used to apply cosmetic substances, then the application process is simple, but the active ingredients cannot reach deeper layers of the skin effectively

Engineering Contradiction:

Improvedelivery depth precisionVSAvoidapplication device complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the physical state and delivery parameters of cosmetic substances by using microencapsulation and controlled release mechanisms. The active ingredients are encapsulated in micro particles that can penetrate deeper skin layers, transforming the delivery method from surface-level application to targeted deep-layer delivery, thereby resolving the contradiction between delivery precision and device complexity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces microencapsulated particles as intermediaries between the cosmetic substance and the skin. These micro particles act as carriers that facilitate deep penetration into skin layers, enabling precise delivery without requiring complex application devices. The intermediary mechanism solves the problem of reaching deeper skin layers while maintaining simple application procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If cosmetic substances are stored in exposed containers, then access is easy, but the active ingredients are exposed to ambient conditions that reduce stability

Engineering Contradiction:

Improveproduct stabilityVSAvoidproduct access ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent employs nested packaging structures where microencapsulated cosmetic particles are contained within sealed containers or cartridges that can be integrated into application devices. This nested arrangement protects the active ingredients from ambient conditions while allowing controlled access during application, thus maintaining both product stability and ease of use.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent stores cosmetic substances in sealed environments that create an inert or protected atmosphere, isolating the active ingredients from degrading ambient conditions such as oxygen and moisture. This protected storage environment maintains product stability while the substances remain ready for controlled dispensing when needed.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Manufacturing precision

If conventional application methods are used, then the application process is quick, but precise control over the affected area is lacking

Engineering Contradiction:

Improveapplication area precisionVSAvoidapplication speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent segments the cosmetic application into controlled portions through microencapsulation and precision dispensing mechanisms. The cosmetic substance is divided into discrete micro particles that can be precisely deposited onto specific skin areas, enabling controlled application with minimal waste while maintaining efficient application speed through the ready-state of the segmented particles.

Inventive Principle:

Principle #1Segmentation

4Measurement precision

If excessive force is applied during cosmetic application, then deeper penetration may be achieved, but skin damage may occur

Engineering Contradiction:

Improvedelivery depth controlVSAvoidskin damage risk

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent employs microencapsulated particles with controlled mechanical properties that cushion the delivery process. The micro particles are designed to penetrate skin layers through their size and structural characteristics rather than requiring excessive external force, thereby achieving deep delivery control while preventing skin damage through built-in mechanical cushioning.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A system for applying a cosmetic substance may include a handheld device with an elongated portion capable of being grasped by a user, a main head body portion coupled to the elongated portion, and an applicator tip seated on the top side of the main head body. The applicator tip is capable of supporting the cosmetic substance to be applied to the skin. A kit may include the system for applying a cosmetic substance and one or more chips comprising the cosmetic substance to be applied to the skin. The one or more chips may include at least one microneedle composed of the cosmetic substance to be applied to the skin. The handheld device of the system may be capable of inserting the at least one microneedle into an epidermal layer of the skin. Each chip may include an array of microneedles composed of the cosmetic substance.
