Solution Overview

Problem

Conventional microdermabrasion devices require large volumes of fluid to deliver active ingredients, leading to inconvenience and wastefulness, especially for home use, as they need constant replenishment and can interfere with the vacuum system.

Innovation Solution

A microdermabrasion device with a treatment tip that incorporates active ingredients in a solid or crystalline form, which are released during use, eliminating the need for a liquid delivery system and allowing for convenient and efficient delivery of active materials without excessive fluid usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If large volumes of fluid are used to deliver active ingredients, then active ingredients can be delivered to the skin, but fluid management becomes inconvenient and wasteful

Engineering Contradiction:

Improvevolume of active ingredient deliveryVSAvoidconvenience of fluid management

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The invention changes the physical state of active ingredients from liquid to solid or crystalline form. This parameter change eliminates the need for large volumes of fluid while maintaining effective delivery to the skin through the microdermabrasion process

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention extracts the active ingredients from the fluid delivery system and incorporates them directly into the microdermabrasion tip. This removes the need for separate fluid management systems and eliminates the inconvenience of constant replenishment

Inventive Principle:

Principle #2Taking out (Extraction)

2Quantity of substance

If liquid delivery systems are used, then active ingredients can be applied, but the vacuum system is interfered with and excessive fluid is used

Engineering Contradiction:

Improveamount of active material deliveredVSAvoidwaste of fluid

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The invention changes the state of active ingredients to solid or crystalline form, which allows them to be delivered without requiring large volumes of liquid. This reduces waste and eliminates interference with the vacuum system while maintaining effective skin delivery

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention merges the active ingredient delivery function with the microdermabrasion tip itself. The solid active ingredients are incorporated into the tip structure, combining abrasion and delivery functions into a single integrated component

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If constant replenishment of fluid is required, then active ingredients can be maintained, but the device becomes inconvenient for home use

Engineering Contradiction:

Improvesupply of active ingredientsVSAvoidcomplexity of fluid management system

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The invention extracts active ingredients from the fluid delivery system and embeds them directly in the microdermabrasion tip. This eliminates the need for separate fluid reservoirs, pumps, and delivery mechanisms, significantly reducing device complexity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The solid active ingredients in the tip are self-contained and do not require external fluid delivery systems or constant replenishment. The tip itself serves as both the abrasion element and the active ingredient delivery mechanism

Inventive Principle:

Principle #25Self-service
