Solution Overview

Problem

Existing technologies face challenges in incorporating therapeutically effective amounts of fat-soluble active ingredients, such as carotenoids and cannabinoids, into multi-particulate materials while maintaining potency and shelf-stability.

Innovation Solution

A composition comprising particles with a lipid matrix core containing a fat-soluble active ingredient, surrounded by one or more outer layers, which are incorporated into oral dosage forms to protect the active ingredients from degradation and maintain stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fat-soluble active ingredients are processed into dry form and micronized down to finer particles to enable layering on inert core, then the active ingredients can be incorporated into multi-particulate materials, but the potency is greatly reduced and stability issues are created in the finished particulate product

Engineering Contradiction:
Improveincorporation of fat-soluble active ingredientsVSAvoidpotency and stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces a lipid matrix as an intermediary carrier that naturally accommodates fat-soluble active ingredients. Instead of directly layering micronized fat-soluble particles onto inert cores (which causes potency loss and stability issues), the lipid matrix serves as a mediating substance that maintains the active ingredients in their native form while enabling incorporation into the multi-particulate system. The lipid matrix core replaces the traditional inert core approach for fat-soluble ingredients, providing both manufacturing feasibility and product reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If inert cores are used as starter material and layered with active ingredient compounds, then the multi-particulate materials can be formed, but fat-soluble active ingredients cannot be effectively incorporated while maintaining potency and shelf-stability

Engineering Contradiction:
Improvemulti-particulate material structureVSAvoidpotency and shelf-stability of fat-soluble active ingredients
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent fundamentally changes the parameter of the core material from inert substances (sucrose, microcrystalline cellulose) to a lipid-based matrix. This parameter change enables the core to naturally interact with and stabilize fat-soluble active ingredients through lipid-lipid compatibility, preventing degradation and maintaining shelf-stability while preserving the multi-particulate structure's complexity for effective drug delivery.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If fat-soluble active ingredients are incorporated into multi-particulate materials using conventional methods, then the dosage formulation can be produced, but the potency and shelf-stability are compromised

Engineering Contradiction:
Improvedosage formulation productionVSAvoidpotency and shelf-stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent creates a composite material system where a lipid matrix core combines with outer layers containing additional active ingredients. This composite structure allows fat-soluble active ingredients to be incorporated effectively while maintaining both potency and shelf-stability. The lipid matrix provides a stable, protective environment for the active ingredients, and the multi-layered composite structure enables efficient dosage formulation production.

Inventive Principle:
Principle #40Composite materials
