Multi-Layer Clothing for Topical Pharmaceutical Delivery

Solution Overview

Problem

Existing methods for topically delivering pharmaceuticals to individuals are inefficient due to difficulties in uniform application and adhesive residue issues, requiring a more practical and economical solution.

Innovation Solution

An article of clothing with multiple layers, including an outer surface layer, an inner layer with a pharmaceutical composition, and a middle breathable barrier layer that prevents the pharmaceutical from passing through, allowing for consistent topical delivery without adhesives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive material is used to apply pharmaceutical to skin, then the pharmaceutical can be delivered to the user, but the adhesive material is difficult and painful to remove or leaves residue on the skin

Engineering Contradiction:

Improvepharmaceutical deliveryVSAvoidremoval and residue

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent removes the adhesive component from the pharmaceutical delivery system entirely. Instead of using adhesive materials to attach the pharmaceutical to the skin, the invention applies the pharmaceutical composition directly to the skin surface through a applicator device, eliminating the harmful adhesive substance and its associated removal problems and skin residue issues.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a non-adhesive intermediary substance or mechanism for pharmaceutical delivery. Rather than using adhesive that bonds to skin, the invention employs a delivery mechanism that transfers the pharmaceutical composition to the skin without requiring adhesive bonding, thus avoiding the residue and removal difficulties associated with traditional adhesives.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If adhesive material is used to apply pharmaceutical to skin, then the pharmaceutical can be delivered to the user, but the application process becomes difficult and painful

Engineering Contradiction:

Solution Approach 1:

The patent removes the adhesive component from the pharmaceutical delivery system entirely. Instead of using adhesive materials to attach the pharmaceutical to the skin, the invention applies the pharmaceutical composition directly to the skin surface through a applicator device, eliminating the harmful adhesive substance and its associated removal problems and skin residue issues.

3Reliability

If traditional topical application methods are used, then pharmaceutical can be applied, but uniform application over affected area and sufficient contact time are difficult to maintain

Engineering Contradiction:

Improvepharmaceutical deliveryVSAvoiduniform application

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent divides the pharmaceutical delivery system into distinct functional components: an applicator device with specific geometric features that segments and controls the flow of pharmaceutical composition, ensuring uniform distribution across the affected area. This segmentation allows for precise control of application patterns and contact time without relying on user technique.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent modifies physical parameters of the delivery system, such as the viscosity, flow rate, and contact time of the pharmaceutical composition, to achieve uniform application. By controlling these parameters through the applicator device design, the system ensures consistent delivery across the affected area and maintains sufficient contact time for effective permeation.

AI summary

An article of clothing is provided for topically delivering a pharmaceutical composition to a wearer of the article of clothing. The clothing typically includes at least three layers, an optional outer surface layer, a middle layer, and an inner layer. A pharmaceutical composition is applied to the inner layer. The middle layer prevents the pharmaceutical composition from passing from the inner layer to the outer surface layer. A method for delivering a pharmaceutical is also disclosed, wherein a pharmaceutical composition is applied to the inner layer of an article of clothing and the clothing is worn by a person. A pharmaceutical preparation delivery kit is also provided, wherein the kit includes an article of clothing for topically delivering a pharmaceutical composition and a pharmaceutical composition.
