Solution Overview

Problem

Current skin and lip care technologies lack effective methods for enhancing the absorption of treatment media into tissue for cosmetic and therapeutic purposes, such as hair restoration, due to limitations in delivering substances deep into the skin or lips.

Innovation Solution

The development of an applicator system with a rolling member and negative pressure mechanism that applies transient negative pressure to the skin or lips, utilizing surface discontinuities to manipulate tissue and enhance permeability, allowing for deeper penetration of treatment media.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional topical application methods are used, then the treatment media can be applied to the skin surface, but the absorption and penetration depth into the tissue is insufficient

Engineering Contradiction:

Improveabsorption of treatment mediaVSAvoidpenetration depth into tissue

Core Design Contradiction:

Quantity of substanceVSLength of stationary object

Solution Approach 1:

The rolling member with surface discontinuities performs preliminary mechanical manipulation of the tissue surface before treatment media application, creating micro-channels and increasing permeability in advance to facilitate deeper penetration of subsequent treatment substances

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Negative pressure is applied through the applicator system to create suction forces that draw treatment media into the tissue deeper than conventional topical application, utilizing pressure differentials to enhance penetration depth and absorption

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Reliability

If the rolling member has surface discontinuities to manipulate tissue, then tissue permeability is enhanced, but the device complexity increases

Engineering Contradiction:

Improvetissue permeability enhancementVSAvoidrolling member structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The rolling member incorporates surface discontinuities including pores, channels, and irregularities that manipulate tissue mechanically while maintaining structural integrity, using controlled porosity and surface features to enhance permeability without requiring overly complex device architecture

Inventive Principle:

Principle #31Porous materials

3Quantity of substance

If negative pressure is applied to enhance penetration, then treatment media absorption improves, but the device complexity and energy consumption increase

Engineering Contradiction:

Improvepenetration of treatment mediaVSAvoidenergy for negative pressure mechanism

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

Negative pressure is applied in a controlled, partial manner rather than continuously at maximum intensity, sufficient to enhance penetration depth without requiring excessive energy input, optimizing the balance between treatment efficacy and energy consumption

Inventive Principle:

Principle #16Partial or excessive action
