Honeycomb Magnetization Pattern for Transdermal Permeation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transdermal permeation of polar and hydrophilic active components is limited by the barrier property of the stratum corneum, and existing anisotropic magnetic arrays with linear magnetization patterns do not generate strong enough magnetic forces for effective delivery.
Innovation Solution
A cosmetic device with an anisotropic magnetic element featuring a honeycomb magnetization pattern, including a plurality of hexagonal zones with alternating North and South polarities, generates a stronger magnetic field to induce diamagnetism and enhance transdermal permeation, using a neodymium rubber magnet with a magnetic flux density between 50 and 1500 gauss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a linear magnetization pattern is used in the anisotropic magnetic array, then the device structure is simple and easy to manufacture, but the magnetic force generated is insufficient for effective transdermal delivery
Solution Approach 1:
The magnetic array is segmented into multiple discrete magnetic elements arranged in a grid pattern, with each element contributing to the overall magnetic field. This segmentation allows the creation of complex honeycomb magnetization patterns from simple individual magnetic elements, resolving the contradiction between generating strong magnetic forces and maintaining manufacturing simplicity
Solution Approach 2:
The patent employs an asymmetric honeycomb magnetization pattern where magnetic elements have different polarities arranged in a specific non-uniform pattern. This asymmetric arrangement creates enhanced magnetic field gradients and stronger net magnetic forces compared to symmetric linear patterns, while the pattern itself provides a systematic manufacturing approach
2Productivity
If stronger magnetic forces are generated to improve transdermal permeation, then the delivery efficacy is enhanced, but the magnetic array requires more complex configuration and larger area
Solution Approach 1:
The patent transitions from one-dimensional linear magnetization patterns to a two-dimensional honeycomb magnetization pattern. This dimensional change allows magnetic elements to be arranged more efficiently in space, creating stronger magnetic fields and better field distribution within a compact area, thereby improving transdermal permeation efficiency without proportionally increasing the array area
3Force
If the magnetic flux density is increased to enhance diamagnetic repulsion, then transdermal delivery is improved, but the risk of magnetic saturation and energy loss increases
Solution Approach 1:
The honeycomb magnetization pattern creates localized regions of high magnetic flux density at specific positions where magnetic elements are closely spaced, while other regions maintain lower flux density. This local quality variation allows strong diamagnetic repulsion forces to be generated at the skin interface without requiring uniformly high flux density across the entire array, thereby reducing overall energy consumption and avoiding magnetic saturation
Solution Approach 2:
The alternating polarity arrangement in the honeycomb pattern creates periodic magnetic field variations that enhance the diamagnetic repulsion effect through constructive interference of magnetic fields. This periodic configuration allows efficient use of magnetic energy, generating strong forces during active phases while reducing energy loss during field transitions, thereby improving transdermal delivery efficiency without proportional energy increase
Applied Scientific Principles

Function Achieved in This Case
The honeycomb magnetization pattern significantly increases the transdermal permeation of active components, as demonstrated by a 219% improvement in penetration efficacy compared to linear magnetization patterns, facilitating deeper skin penetration of cosmetic and pharmaceutical compositions.
Implementation Method 1
Diamagnetism is the property of a substance to induce a magnetic field in a direction opposite to an applied external magnetic field, and therefore, to be repelled by the applied external magnetic field. It is a promising non-invasive transdermal delivery for small organic molecules that are diamagnetic in nature.
Implementation Method 2
an anisotropic magnetic element located in or on the head part of the body, the anisotropic magnetic element configured to generate a magnetic field and to induce diamagnetism in the active component
