Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current treatments for osteoarthritis, such as painkillers and joint surgery, have severe side effects and are not entirely effective, while phyto cannabinoids face challenges like low bioavailability and unclear modes of action, hindering their widespread use for pain relief.

Innovation Solution

A formulation comprising cannabinoid dimers or oligomers linked through amine, ether, thioether, or amido groups with a biodegradable polymer, combined with amine/amide anesthetics, forms microsphere systems for synergistic pain relief, providing prolonged and minimally invasive treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional painkillers and NSAIDs are used for osteoarthritis treatment, then pain relief is achieved, but severe side effects occur

Engineering Contradiction:

Improvepain relief efficacyVSAvoidside effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines cannabinoids with conventional painkillers and NSAIDs in a single formulation, allowing the synergistic interaction between these substances to enhance pain relief while the cannabinoid component mitigates the harmful side effects of conventional drugs through anti-inflammatory and neuroprotective mechanisms

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Cannabinoids act as intermediary substances that modulate the interaction between conventional painkillers and the body's pain pathways, providing alternative mechanisms of pain relief that reduce dependence on conventional drugs and their associated side effects

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If joint surgery or joint replacement is performed for osteoarthritis, then pain is relieved, but high cost and invasiveness are imposed

Engineering Contradiction:

Improvepain reliefVSAvoidinvasiveness and cost

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary pharmacological intervention using cannabinoid-based formulations to manage osteoarthritis pain and inflammation before disease progression requires surgical intervention, thereby avoiding the high cost and invasiveness of joint replacement surgery while maintaining effective pain relief

Inventive Principle:

Principle #10Preliminary action

3Reliability

If phyto cannabinoids are used for pain relief, then therapeutic effects are achieved, but low bioavailability and unclear modes of action hinder widespread use

Engineering Contradiction:

Improvetherapeutic effectVSAvoidbioavailability

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent uses conventional painkillers and NSAIDs as intermediary substances that enhance the bioavailability and absorption of cannabinoids in the body, creating a synergistic effect where these drugs facilitate better delivery and utilization of cannabinoid therapeutic agents while maintaining their own pain relief effects

Inventive Principle:

Principle #24Intermediary (Mediator)
