Solution Overview

Problem

Current therapies for severe pain are limited, often requiring frequent dosing and causing undesirable systemic side effects, and do not provide complete pain relief, highlighting the need for a therapeutic option that offers sustained relief while minimizing side effects.

Innovation Solution

A solid solution pharmaceutical composition comprising propionic acid derivative NSAIDs, room temperature solid lipids, and liquid lipids, formulated to create a lipid-adjuvant delivery system that effectively targets therapeutic compounds to inflamed tissues using chylomicrons and dendritic cells, allowing for sustained pain relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional pain therapies are used, then pain relief is achieved, but frequent dosing is required and systemic side effects occur

Engineering Contradiction:
Improvepain relief effectivenessVSAvoidsystemic side effects
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by formulating the NSAID in a solid solution with specific lipid components (triglycerides, monoglycerides, diglycerides) that enable targeted delivery to inflamed tissues through chylomicrons. This localized delivery mechanism concentrates the therapeutic compound at the site of pain while minimizing distribution to other body systems, thereby reducing systemic side effects while maintaining pain relief effectiveness.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses lipid molecules as intermediaries to carry the NSAID from the gastrointestinal tract to inflamed tissues. The solid solution formulation with specific lipid ratios (triglycerides 50-90%, monoglycerides 5-30%, diglycerides 5-30%) creates a delivery vehicle that mediates between the drug and target tissue, enabling sustained release and targeted accumulation in inflamed areas while avoiding widespread systemic exposure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional pain therapies are used, then pain relief is achieved, but multiple medications are required and drug-drug interactions occur

Engineering Contradiction:
Improvepain relief effectivenessVSAvoidmedication regimen complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the NSAID with specific lipid components in a single solid solution formulation. This combination creates a unified therapeutic product that eliminates the need for multiple separate medications, simplifying the patient regimen while maintaining effective pain relief through the synergistic action of the lipid-adjuvant delivery system.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional pain therapies are used, then pain relief is achieved, but complete pain relief is not provided

Engineering Contradiction:
Improvepain relief completenessVSAvoidduration of pain relief
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent achieves continuous pain relief through the solid solution formulation that provides sustained release of the NSAID. The lipid-based delivery system ensures continuous accumulation of the drug in inflamed tissues over time, maintaining therapeutic levels and providing prolonged pain relief without the need for frequent dosing interruptions.

Inventive Principle:
Principle #20Continuity of useful action

4Ease of operation

If solid solution formulation is used, then targeted delivery to inflamed tissues is achieved, but formulation complexity increases

Engineering Contradiction:
Improvetargeted delivery efficiencyVSAvoidformulation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent achieves targeted delivery by carefully controlling the physical and chemical parameters of the solid solution formulation. Specific ratios of lipid components (triglycerides 50-90%, monoglycerides 5-30%, diglycerides 5-30%) and the melting point range (30-45°C) are optimized to enable proper solubility, stability, and biological activity. These parameter optimizations allow the complex formulation to function effectively while maintaining manufacturability.
