Solution Overview

Problem

Existing drug formulations face challenges in achieving high concentrations of diverse active ingredients with targeted and defined release profiles, particularly in providing oral administration and avoiding immune system responses.

Innovation Solution

Active ingredient compositions containing at least two types of micelles, each with a core containing an active ingredient and a shell of polyelectrolytes and/or glycerol esters, with a mean geometric diameter of 5-100 nm, allowing for targeted and controlled release of active ingredients in the gastrointestinal tract.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high concentrations of diverse active ingredients are provided in drug formulations, then the therapeutic efficacy is improved, but the stability and controlled release profile deteriorate

Engineering Contradiction:
Improveconcentration of active ingredientsVSAvoidstability and controlled release profile
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The formulation segments diverse active ingredients into separate micellar carriers with different shell compositions. Each micelle type is optimized for specific active ingredients, allowing high concentrations of multiple ingredients to coexist stably without interfering with each other's release profiles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses composite micellar structures with different shell materials (polyelectrolytes and/or glycerol esters) to create a multi-component delivery system. This composite approach allows simultaneous incorporation of diverse active ingredients while maintaining individual stability and controlled release characteristics for each ingredient type.

Inventive Principle:
Principle #40Composite materials

2Manufacturing precision

If targeted and defined release profiles are provided, then the therapeutic precision is improved, but the formulation complexity increases

Engineering Contradiction:
Improvetargeted and defined release profileVSAvoidformulation complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Different micelle types are assigned different shell compositions and properties tailored to specific active ingredients and their desired release characteristics. This local optimization allows each micelle population to have a defined release profile suited to its cargo, achieving therapeutic precision without requiring a single complex formulation design.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention controls release profiles by varying micelle parameters such as shell composition (polyelectrolyte type, glycerol ester type), shell thickness, and micelle size. These parameter adjustments provide targeted release without increasing overall formulation complexity, as each parameter change directly translates to a specific release characteristic.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If micelles are administered orally, then the ease of administration is improved, but the risk of immune system response increases

Engineering Contradiction:
Improveease of administrationVSAvoidimmune system response
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The micelle size parameter is optimized to fall within the 5-100 nm range, which is small enough to evade immune detection by macrophages and other immune cells. This size parameter change allows oral administration to proceed without triggering significant immune responses, maintaining ease of administration while reducing harmful immune effects.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The polyelectrolyte and glycerol ester shell materials act as intermediaries that protect the active ingredients from immune recognition while allowing oral passage. These biocompatible shell materials mediate between the potentially immunogenic active ingredients and the immune system, enabling oral administration without triggering immune responses.

Inventive Principle:
Principle #24Intermediary (Mediator)
