Dermal Adhesive Patch Nanofiber Membrane Breathability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beauty masks and medical tapes are not breathable, leading to skin troubles and inefficiencies in delivering skincare ingredients, as they fail to effectively block moisture and allow air penetration.
Innovation Solution
A dermal adhesive patch with a nanofiber web membrane layer that blocks moisture and allows air to pass through, formed by electrospinning a synthetic polymer and solvent mixture, which is detachably laminated on a support body and contains a mixed ampoule with ingredients for skin care, including a dry-storage material that facilitates penetration of functional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional medical tape is used to cover medicine on skin, then moisture blocking is improved, but breathability deteriorates causing skin troubles
Solution Approach 1:
The patent employs a nanofiber web membrane layer with controlled porosity that allows air and water vapor to pass through while blocking liquid moisture. The nanofiber structure creates interconnected pores that enable breathable functionality while maintaining moisture barrier properties, thus preventing skin troubles caused by poor ventilation.
Solution Approach 2:
The patent uses a composite structure combining a support body with a nanofiber web membrane layer. This composite material approach integrates the mechanical strength of the support body with the selective permeability of the nanofiber membrane, achieving both moisture blocking and breathability simultaneously.
2Ease of manufacture
If conventional beauty masks made of woven or non-woven fabric are used, then ease of manufacture is improved, but liquid essence runs down due to weight causing inconvenience
Solution Approach 1:
The nanofiber web membrane layer utilizes its porous structure to capillary-absorb and retain liquid essence within the fiber network. This prevents liquid from running down while maintaining the ease of manufacturing associated with fabric-based masks.
3Reliability
If a nanofiber web membrane layer with micropores is used to block moisture, then moisture blocking is improved, but device complexity increases due to electrospinning process
Solution Approach 1:
The patent employs electrospinning, an electrostatic field-based process, to create the nanofiber web membrane layer instead of traditional mechanical weaving or bonding methods. This substitution enables the formation of fine nanofiber structures with controlled porosity that would be difficult to achieve through conventional mechanical means.
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 patch maximizes the effectiveness of skincare ingredients while preventing skin troubles by maintaining breathability and blocking UV rays, allowing for the long-term use of skincare ingredients without causing skin maceration or exposure to the outside environment.
Implementation Method 1
a membrane layer which is formed as a nanofiber web having micropores to block moisture and to allow air to pass through the membrane layer
Implementation Method 2
The membrane layer may be a nanofiber web formed to have micropores by electrospinning a spinning solution, in which a synthetic polymer and a solvent are mixed
Implementation Method 3
effects of moisture blocking, breathability, and ultraviolet ray blocking caused by diffuse-reflection can be obtained
Implementation Method 4
The functional component may include a dry-storage material which is difficult to store in a liquid state
