Solution Overview

Problem

Current transdermal delivery methods for cannabinoids often rely on harsh penetration enhancers like solvents and phospholipids, which can irritate the skin, and existing skin protecting/enhancing ingredients are not effectively delivered to the top of the skin without causing irritation or absorption.

Innovation Solution

Development of compositions that deliver cannabinoids transdermally in therapeutically effective amounts without phospholipids or harsh penetration enhancers, while simultaneously delivering skin protecting/enhancing ingredients topically, using a bimodal pharmaceutical carrier that includes cannabinoids, skin protecting agents, and antioxidants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If solvent-based penetration enhancers (DMSO, alcohols, glycols) are used for transdermal delivery, then cannabinoid delivery effectiveness is improved, but skin irritation occurs

Engineering Contradiction:
Improvecannabinoid delivery effectivenessVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes harmful penetration enhancers (solvents like DMSO, alcohols, glycols) from the formulation entirely, replacing them with a solvent-free system that uses the cannabinoid compounds themselves and benign carriers to achieve transdermal delivery without skin irritation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs simple, benign, short-acting carriers such as fatty acids, esters, and terpenes that naturally degrade and are rapidly metabolized by the skin, replacing persistent solvent-based enhancers with transient, safe alternatives that provide sufficient delivery without long-term irritation

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If phospholipids (lecithin) are used for transdermal delivery, then cannabinoid penetration is improved, but skin irritation and allergic reactions occur

Engineering Contradiction:
Improvecannabinoid penetrationVSAvoidskin irritation and allergic reactions
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes phospholipids (particularly lecithin) from the formulation, eliminating the source of skin irritation and allergic reactions while maintaining transdermal delivery effectiveness through alternative mechanisms using fatty acids and terpenes

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces intermediary substances such as fatty acids, esters, and terpenes that act as mild carriers and penetration facilitators, replacing phospholipids with substances that mediate cannabinoid delivery without triggering immune responses or skin irritation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If skin protecting/enhancing ingredients are delivered topically, then skin condition improvement is achieved, but these ingredients are not effectively retained on the skin surface

Engineering Contradiction:
Improveskin condition improvementVSAvoidingredient retention on skin surface
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent creates a composite formulation where skin protecting ingredients (antioxidants, moisturizers, anti-inflammatory agents) are combined with cannabinoid compounds and fatty acid carriers in a single integrated system that delivers all components synergistically, ensuring both cannabinoids penetrate and protective ingredients remain on the skin surface

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent merges transdermal delivery of cannabinoids with topical delivery of skin protecting ingredients into a single formulation application, combining multiple therapeutic functions (pain relief, inflammation reduction, skin protection, moisturization) in one product that simultaneously addresses both deep tissue and surface skin needs

Inventive Principle:
Principle #5Merging (Combining)
