Solution Overview

Problem

Existing delivery systems for functional ingredients, particularly amphipathic and oil-soluble ingredients, face challenges in achieving optimal solubility and release characteristics, leading to inefficient dosage and potential damage during manufacturing, and often require high doses to compensate for solubility issues.

Innovation Solution

A delivery system using an expanded foam matrix composed of whisked egg white, heat-resistant gelling agents, pH regulators, plasticizers, humectants, and water, which uniformly disperses functional ingredients, enhancing solubility and release by concentrating them at the foam-air interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional solid matrices (confectionery, glassy, sintered) are used to deliver functional ingredients, then the active ingredient is retained and delivered according to dissolution rate, but the active ingredient may suffer from deterioration or damage due to heat and mechanical stresses in manufacturing, and overdosing is required to compensate for strong processing conditions

Engineering Contradiction:
Improvestability of functional ingredientVSAvoidmanufacturing process conditions
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the physical state of the delivery matrix from solid (confectionery, glassy, sintered) to semi-solid (expanded foam) with controlled foam expansion. This parameter change allows incorporation of heat-sensitive functional ingredients without subjecting them to extreme manufacturing conditions, while maintaining delivery effectiveness through the foam structure's controlled dissolution and release properties

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite delivery system combining foam matrix (providing gentle, low-stress structure), functional ingredients (active components), and excipients (facilitating solubility and release). This composite approach allows each component to contribute its strengths: the foam provides a gentle matrix that doesn't damage sensitive ingredients, while excipients enhance solubility and controlled release without requiring overdosing

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If high doses of functional ingredient are used to compensate for solubility issues in conventional formulations, then adequate dosage is achieved, but cost increases due to wastage of active ingredient

Engineering Contradiction:
Improveavailable dose of functional ingredientVSAvoidwastage of active ingredient
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent changes the solubility parameters of the functional ingredient delivery system by using foam matrix and excipients that enhance solubility. This allows adequate dosing with lower amounts of active ingredient, reducing wastage while maintaining therapeutic effectiveness. The foam structure and excipient selection optimize the solubility-release profile to maximize bioavailability of the functional ingredient

Inventive Principle:
Principle #35Parameter changes

3Reliability

If functional ingredients are incorporated into pressed tablets or glassy matrices, then delivery according to dissolution rate is achieved, but the solid taste in the mouth is considered unattractive, especially for unpalatable active ingredients

Engineering Contradiction:
Improvecontrolled release of active ingredientVSAvoidpalatability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the physical form from hard solid (tablet, glassy matrix) to semi-solid expanded foam. This parameter change improves palatability by providing a softer, more pleasant mouthfeel that masks unpalatable active ingredients, while maintaining controlled release through the foam's structured dissolution and excipient-mediated release mechanisms

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite foam formulation that combines the functional ingredient with excipients designed to enhance both solubility and palatability. The excipients serve dual functions: facilitating controlled release of the active ingredient and improving sensory characteristics (taste, texture) to make unpalatable ingredients more acceptable to consumers

Inventive Principle:
Principle #40Composite materials
