Solution Overview
Problem
Existing topical treatments for plaque psoriasis are messy, inconvenient, and take time to provide effective relief, lacking a secure and efficient method for delivering medication to treat redness, itchiness, and discomfort.
Innovation Solution
A topical patch device with a flexible, porous body component infused with medicinal ingredients, including analgesic and drying agents, secured by a pressure-sensitive adhesive, which can be applied directly to the skin to deliver medication effectively and quickly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional topical treatments (foams, lotions, ointments) are used, then medication can be applied to the skin, but the application is messy and inconvenient
Solution Approach 1:
The patent employs a flexible adhesive patch that forms a thin film barrier between the medication and the environment. This film-based approach contains the medication in a controlled-release matrix, preventing the messiness associated with traditional liquid or foam formulations while maintaining ease of application through simple adhesive bonding to the skin.
Solution Approach 2:
The adhesive patch acts as an intermediary carrier that delivers medication to the skin in a controlled manner. The patch matrix serves as a reservoir and release mechanism, mediating between the medication formulation and the skin surface to eliminate the need for direct hand-to-skin application of messy substances.
2Reliability
If traditional topical treatments are used, then medication can be applied to the skin, but they take time to provide effective relief
Solution Approach 1:
The patch is pre-loaded with medication in a formulated matrix that is designed for controlled release. The medication is positioned and prepared in advance within the patch structure, allowing immediate engagement with the skin upon application. This preliminary preparation eliminates the waiting time associated with traditional treatments that require absorption through liquid or foam formulations.
Solution Approach 2:
The adhesive patch provides continuous medication delivery through its controlled-release matrix structure. The patch maintains constant contact with the skin via the adhesive bond, ensuring continuous medication release and penetration throughout the wear period, thereby achieving faster and more reliable relief compared to intermittent application of traditional topicals.
3Reliability
If a patch is designed to deliver medication effectively, then medication delivery is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated patch structure: the adhesive layer provides both skin attachment and a barrier function, while the matrix material simultaneously serves as the medication reservoir and the controlled-release delivery system. This consolidation eliminates the need for separate components, reducing device complexity while maintaining effective medication delivery.
Solution Approach 2:
The patch matrix material performs multiple functions simultaneously: it acts as the structural body of the patch, the medication carrier, the controlled-release mechanism, and the interface with the skin. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure while achieving reliable medication delivery.

AI summary
A topical patch device is disclosed, which is designed for the relief and control of psoriasis through delivering medication directly into the skin. The topical patch device comprises a body component which is a patch that is configured in a variety of shapes. The body component comprises medicinal ingredients designed to treat psoriasis. Further, the body component comprises a protective adhesive backing that can be peeled away once application is needed to expose the medicinal ingredients. Users can then secure the patch to an affected area to obtain a better, more consistent method of absorbing medication when compared to foams and lotions.
