Rolling Applicator with Negative Pressure for Skin Media Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skin and lip care devices lack effective methods for enhancing the absorption of treatment media into tissue for cosmetic and therapeutic purposes, such as hair restoration, as they primarily rely on liquid delivery rather than tissue manipulation and negative pressure.
Innovation Solution
The development of an applicator system with a rolling member and negative pressure mechanism that manipulates tissue by creating transient negative pressure, using surface discontinuities to enhance permeability and absorption of treatment media into the skin or lips, which includes features like abrasive surfaces, micro-needles, and LED light emission for additional penetration and rejuvenation effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid delivery methods are used for treatment media application, then the device structure is simple, but the absorption of treatment media into tissue is insufficient
Solution Approach 1:
The rolling member is segmented with surface discontinuities including recesses, channels, grooves, notches, facets, bores, and porosities. These segmented structures create multiple pathways for treatment media delivery and tissue manipulation, enhancing absorption while maintaining a relatively simple overall device structure.
Solution Approach 2:
The rolling member incorporates porous structures that allow treatment media to penetrate through the rolling member itself and be delivered directly into the tissue. The porous material enables controlled release and enhanced absorption of treatment media while adding minimal structural complexity.
2Manufacturing precision
If tissue manipulation and negative pressure are applied, then the penetration of treatment media is enhanced, but the device complexity increases
Solution Approach 1:
The device merges multiple functions into a single rolling member: mechanical tissue manipulation through rolling action, negative pressure application through integrated vacuum mechanisms, and treatment media delivery through porous structures. This consolidation enhances penetration depth while avoiding the complexity of separate devices for each function.
Solution Approach 2:
The rolling member performs preliminary tissue manipulation and creation of micro-channels before treatment media application. The rolling action with surface discontinuities pre-prepares the tissue by creating micro-traumas and increasing permeability, allowing subsequent treatment media to penetrate more effectively.
3Reliability
If surface discontinuities are added to the rolling member, then the permeability enhancement is improved, but the manufacturing complexity increases
Solution Approach 1:
The rolling member's surface properties are modified by changing physical parameters such as creating recesses, channels, grooves, notches, facets, bores, and porosities. These parameter changes enhance permeability and treatment media delivery while being achievable through standard manufacturing techniques like machining, molding, or additive manufacturing.
4Manufacturing precision
If abrasive surfaces and micro-needles are incorporated, then the tissue penetration is enhanced, but the device complexity and potential harm increase
Solution Approach 1:
The rolling member incorporates abrasive surfaces and micro-needles only in specific localized regions rather than uniformly across the entire surface. This localized application provides targeted tissue penetration where needed while minimizing unnecessary tissue damage in other areas, balancing effectiveness with safety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively enhances the penetration and absorption of treatment media into the skin or lips, improving cosmetic and therapeutic outcomes, including hair growth, by manipulating tissue and using negative pressure to draw substances deeper into the tissue layers.
Implementation Method 1
a negative pressure mechanism communicating with a flow pathway in the applicator tip for applying negative pressure to tissue engaged by the applicator tip
Implementation Method 2
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 3
enhance absorption of treatment media into tissue for cosmetic and therapeutic purposes
Implementation Method 4
creating transient negative pressure to enhance permeability of the tissue surface
Implementation Method 5
the surface of the rolling member can include recessed portions and adjacent projecting portions... at least a portion of the rolling member has an abrasive surface
