Herbal Medicine Pad with Segmented Particle Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbal medicine delivery pads fail to control the release and penetration of medicinal ingredients into the skin effectively, leading to inconsistent therapeutic effects and inability to vary the rate of penetration based on the specific drug ingredients, making it difficult to achieve persistent and controlled drug delivery.
Innovation Solution
A pad for herbal medicine is manufactured by separating and grinding medicinal ingredients into fine particles of different sizes based on desired release duration, mixing them with a binding agent like maltodextrin or natural polymers, and adhering them to a base sheet, which can be enhanced with a magnetic or low-frequency permeation activating unit for controlled release through the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If electric field or magnetic field is applied to accelerate drug penetration into the skin, then the penetration speed is improved, but the persistence and controllability of drug administration rate deteriorates
Solution Approach 1:
The medicinal ingredient layer is divided into multiple sub-layers, each containing different medicinal ingredients with different particle sizes. This segmentation allows each layer to control the release rate of specific ingredients independently, enabling persistent and controllable drug administration while maintaining fast penetration through the skin.
Solution Approach 2:
Different regions of the medicinal ingredient layer have different properties - specifically, different particle sizes of medicinal ingredients are placed in different layers. This local differentiation enables each layer to have optimized penetration and release characteristics, resolving the contradiction between fast penetration and persistent controlled release.
2Device complexity
If a single medicinal ingredient layer is used in the pad, then the device structure is simple, but the ability to control different release rates for different medicinal ingredients deteriorates
Solution Approach 1:
The medicinal ingredient layer is segmented into multiple sub-layers with different medicinal ingredients and particle sizes. This segmentation provides the versatility to control release rates for different ingredients while maintaining a relatively simple overall pad structure that can be manufactured efficiently.
Solution Approach 2:
The pad uses a composite structure with multiple medicinal ingredient layers containing different ingredients and particle sizes. This composite approach enables differentiated release control for various medicinal ingredients while maintaining structural simplicity and manufacturing feasibility.
3Productivity
If medicinal ingredients are ground to fine particles to enhance penetration, then the penetration efficiency is improved, but the release duration and persistence deteriorate
Solution Approach 1:
Medicinal ingredients are ground to different particle sizes and placed in different layers. Finer particles in upper layers provide fast penetration efficiency, while coarser particles in lower layers ensure prolonged release duration. This segmented approach resolves the contradiction between penetration efficiency and release duration.
Solution Approach 2:
The particle size parameter of medicinal ingredients is varied across different layers - finer particles for efficient penetration and coarser particles for sustained release. This parameter differentiation allows the system to achieve both high penetration efficiency and extended release duration simultaneously.
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 pad allows for controlled and persistent release of medicinal ingredients, maximizing therapeutic effects by varying the release rate and duration, enabling long-term storage and efficient delivery through the skin or respiratory organs, enhancing treatment convenience and commercial value.
Implementation Method 1
The pad may further comprise a medicinal ingredient permeation activating unit provided on base sheet or between the medicinal ingredient layer and the base sheet, and the medicinal ingredient permeation activating unit may comprise a magnet or a low frequency generator
Implementation Method 2
mixing them with a binding agent like maltodextrin or natural polymers

AI summary
A method for manufacturing a pad for herbal medicine in which the release of medicinal ingredients can be controlled, which comprises: separating two or more medicinal herbal ingredients prescribed or prepared according to pharmacological effects on the basis of the weight ratio of each medicinal ingredient to total weight of the medicinal ingredients; grinding the medicinal ingredients separated on the basis of weight ratio, wherein fine particles are ground to different sizes according to the setting of release duration; preparing herbal medicine by mixing the ground medicinal ingredients together, and then mixing the ingredients with a binding agent; and adhering the herbal medicine to a base sheet. The pad for herbal medicine manufactured according to the method allows for persistent permeation of medical ingredients through the skin with different release rate for each medicinal ingredient, thus maximizing the efficacy of the medicinal ingredient layer and the effect of treating disease.
