Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for delivering active compounds transdermally or topically are complex, expensive, and fail to provide controlled release, leading to ineffective dosages and unsustained benefits, with most being suitable for single-use only.
Innovation Solution
A delivery device with a first portion that includes an active compound, such as a cannabinoid, designed to maintain a tack of at least 25% after application, allowing for controlled release and reusable use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known systems and methods are used for delivering active compounds transdermally or topically, then the delivery can be achieved, but the systems are complex and expensive
Solution Approach 1:
The delivery device is segmented into distinct functional layers: a first portion containing the active compound and a second portion providing structural support. This segmentation allows each layer to be optimized independently, simplifying the overall system while maintaining delivery effectiveness.
Solution Approach 2:
The first portion of the device serves multiple functions: it contains the active compound, provides controlled release through its matrix structure, and maintains skin adhesion. This multi-functionality eliminates the need for separate components, reducing system complexity and cost.
2Reliability
If known systems and methods are used for delivering active compounds, then delivery can be achieved, but they fail to release the active compound in a controlled manner
Solution Approach 1:
The first portion utilizes changes in physical parameters (temperature, pH, moisture) experienced by the skin to control the release rate of the active compound. This allows predictable, controlled delivery without complex mechanical or electronic controls.
Solution Approach 2:
The first portion employs a porous matrix structure that controls active compound release through diffusion pathways. The pore size and distribution are engineered to provide sustained, controlled release over time, ensuring effective dosage delivery.
3Reliability
If known methods and systems are used, then delivery can be achieved, but they are only suitable for a single use
Solution Approach 1:
The device is designed to maintain skin adhesion and active compound release capability over multiple uses. The first portion retains sufficient active compound and adhesive properties after initial use, enabling repeated application and extending the useful life of the device.
Solution Approach 2:
The device structure allows for recovery and reuse of the first portion after initial use. The resilient second portion maintains structural integrity, enabling the first portion to be reapplied or the device to be reused multiple times, reducing material waste.
4Reliability
If the first outer surface delivers the active compound, then the active compound is released, but the tack decreases significantly
Solution Approach 1:
The device structure allows different portions to have different properties: the first portion is optimized for active compound release while the second portion provides structural support and maintains overall device integrity. This local differentiation allows the first portion to deliver active compound without compromising overall adhesive strength.
Solution Approach 2:
The device combines different materials in the first and second portions to achieve complementary functions. The composite structure allows the first portion to have controlled release properties while the second portion provides mechanical strength and additional adhesion, maintaining overall tack despite active compound delivery from the first portion.

AI summary
A method of delivering an active compound includes providing a delivery device having a first portion. The first portion defines a first outer surface of the device. An active compound is provided in the first portion. The first outer surface exhibits a first tack after providing the active compound and a second tack of at least 25 percent the first tack after delivering the active compound to the first outer surface.
