Vacuum Abrading Head for Skin Cell Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin abrading technologies often cause irritation, striping, and incomplete removal of dead skin cells, and may not effectively maintain intimate contact with the skin surface during the abrading process.
Innovation Solution
A hand-held apparatus with a skin abrading head featuring a smooth rim and a brush with bristles, connected to a vacuum source through an air-flow passageway, which creates a vacuum-induced air flow to entrain and remove abraded skin cells while maintaining contact with the skin, reducing irritation and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an abrasive tip is moved over the skin surface with vacuum application, then dead skin cells are removed and skin surface is cleaned, but skin irritation and striping may occur
Solution Approach 1:
The abrasive surface is segmented into multiple discrete abrasive elements (diamond particles, aluminum oxide, etc.) distributed across the treatment surface, allowing selective engagement with skin cells while distributing mechanical stress to prevent concentration of force that causes striping and irritation
Solution Approach 2:
A vacuum field is introduced as an intermediary mechanism to assist skin-cell removal. The vacuum creates negative pressure that draws abraded cells away from the skin surface and toward the collection chamber, reducing the mechanical force needed from the abrasive elements alone and thereby minimizing skin irritation
2Reliability
If vacuum is applied through the tube to hold skin in contact with abrasive tip, then intimate contact is maintained during treatment, but incomplete removal of dead skin cells may occur
Solution Approach 1:
The system dynamically balances vacuum pressure and abrasive motion. The vacuum pressure is maintained at an optimal level to ensure skin contact without excessive force, while the abrasive elements continuously move across the skin surface to progressively remove dead cells, preventing the vacuum alone from causing incomplete removal
Solution Approach 2:
The abrasive treatment is applied continuously as the device moves across the skin surface, with the vacuum operating throughout the entire treatment process. This continuous action ensures that dead skin cells are progressively removed without interruption, achieving complete removal while maintaining reliable skin contact
3Device complexity
If traditional abrasive methods are used without vacuum, then device complexity is reduced, but skin contact maintenance and debris removal efficiency decrease
Solution Approach 1:
The vacuum system serves multiple functions simultaneously: (1) holding the skin in intimate contact with the abrasive surface, (2) drawing abraded cells away from the treatment area, and (3) transporting debris to the collection chamber. This multi-functionality justifies the added complexity by significantly improving treatment efficiency in a single integrated system

AI summary
A system for abrading skin to remove outer portions thereof includes an apparatus having a skin abrading head with a head portion and a skin abrading brush. The outer head portion has a rim for placement in contact with the skin along with the bristles of the brush. Air flow is generated in the head to bring the skin into engagement with the rim and bristles and transport removed skin portions.
