Solution Overview

Problem

Existing pain relief medications, such as morphine and antidepressants, have significant side effects and variability in efficacy due to gastrointestinal absorption, while cannabinoid-based treatments face challenges with bioavailability and stability in the oral cavity.

Innovation Solution

A transmucosal patch comprising electrospun fibers with biocompatible polymers and a combination of cannabinoids and opioids, designed for immediate or controlled release, adheres to the oral mucosa for direct absorption, optimizing bioavailability and minimizing side effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional pain relief medications (morphine, opioids) are used, then effective pain relief is achieved, but side effects and risk of overdosing increase

Engineering Contradiction:
Improvepain relief efficacyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines cannabinoids and opioids in a single transmucosal patch formulation. This composite approach allows the cannabinoids to modulate the effects of opioids, potentially reducing required opioid doses and associated side effects while maintaining pain relief efficacy. The electrospun fiber matrix integrates both active ingredients for协同 action.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

Cannabinoids act as intermediary substances that modulate opioid reception and effect. The patch delivers cannabinoids alongside opioids, where cannabinoids serve as mediators to enhance pain relief while reducing the harmful effects of opioids, such as respiratory depression and addiction potential.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If cannabinoids are administered orally, then treatment is simple, but bioavailability is poor due to first-pass metabolism

Engineering Contradiction:
Improveadministration simplicityVSAvoidbioavailability
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts cannabinoids from oral administration pathway by using transmucosal delivery. The electrospun patch bypasses gastrointestinal absorption and hepatic first-pass metabolism by delivering cannabinoids directly through the oral mucosa into systemic circulation, thereby extracting the harmful metabolic pathway while maintaining administration simplicity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If electrospun fibers are used for transmucosal delivery, then bioavailability is improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovebioavailabilityVSAvoidmanufacturing process
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent optimizes electrospinning parameters (voltage, flow rate, needle-to-collector distance, polymer concentration) to control fiber morphology, size, and drug loading. By systematically adjusting these parameters, the manufacturing process achieves consistent high-quality patches with controlled drug release profiles, balancing manufacturing complexity with improved bioavailability.

Inventive Principle:
Principle #35Parameter changes
