Lip Applicator Roller Using Negative Pressure for Deeper Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic and therapeutic treatments struggle to effectively enhance the absorption of treatment media into skin and lips, lacking efficient methods to penetrate and deliver substances beyond the surface layers.
Innovation Solution
An applicator system with a rolling member and negative pressure mechanism that manipulates tissue through surface discontinuities to create transient negative pressure, enhancing permeability and facilitating the penetration of treatment media into subsurface tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional topical application methods are used, then treatment media can be applied to the skin surface, but absorption and penetration into subsurface tissue is insufficient
Solution Approach 1:
The rolling member is segmented with multiple surface discontinuities (protrusions, recesses, channels) that create multiple pathways for treatment media delivery. This segmentation allows the device to penetrate tissue barriers more effectively while maintaining a relatively simple overall structure.
Solution Approach 2:
The rolling member applies periodic mechanical action through rotation, creating transient negative pressure in pulses as it moves across the tissue. This periodic compression and decompression enhances permeability temporarily, allowing treatment media to penetrate deeper into subsurface tissue without requiring continuous high complexity mechanisms.
2Quantity of substance
If mechanical pressure is applied to enhance penetration, then treatment media can reach subsurface tissue, but tissue damage may occur
Solution Approach 1:
The rolling member applies intermittent mechanical pressure through its rotation rather than continuous pressure. This periodic action creates transient negative pressure that enhances permeability temporarily, allowing treatment media to penetrate without causing permanent tissue damage. The rolling motion naturally provides recovery time between pressure applications.
Solution Approach 2:
The surface discontinuities on the rolling member (protrusions, recesses, channels) change the mechanical parameters of tissue interaction. These features create localized areas of high and low pressure that dynamically change as the roller rotates, enhancing penetration while distributing mechanical stress to prevent concentrated damage.
3Quantity of substance
If a rolling member with surface discontinuities is used, then tissue permeability is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The surface discontinuities (protrusions, recesses, channels) on the rolling member create dynamic parameter changes during rotation. Rather than requiring extremely precise static features, the design leverages the rotational motion to generate the necessary pressure variations and tissue manipulation, reducing manufacturing precision requirements while maintaining permeability enhancement effectiveness.

Function Achieved in This Case
The system effectively increases the absorption and penetration of treatment media into skin and lips by manipulating tissue with negative pressure, improving the delivery of substances such as hyaluronic acid and moisturizers.
Implementation Method 1
creating negative pressure about the rolling member in contact with the tissue surface to transiently cause negative pressure in subsurface tissue to enhance permeability of the tissue surface
Implementation Method 2
the surface discontinuities of the rolling member causing at least one of compressing, stretching, tensioning, and piercing the tissue surface
Implementation Method 3
the moving step abrades the tissue surface with an abrasive surface of the applicator body to thereby enhance penetration of the treatment media therein
