Solution Overview

Problem

Current prebiotics used in infant formulas do not replicate the short-chain fatty acid (SCFA) profile of breast milk, leading to potential gastrointestinal issues such as excess gas, bloating, and diarrhea, while also failing to effectively promote beneficial bacteria like Bifidobacteria.

Innovation Solution

Incorporating polydextrose (PDX) and galacto-oligosaccharides (GOS) into infant formulas at specific concentrations to simulate the functional attributes of human milk oligosaccharides, thereby increasing beneficial bacteria and optimizing the SCFA profile to resemble that of breast-fed infants, while reducing fermentation rates and gas production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional prebiotics are used in infant formulas, then beneficial bacteria growth is promoted, but gastrointestinal discomfort (gas, bloating, diarrhea) increases

Engineering Contradiction:
Improvebeneficial bacteria promotionVSAvoidgastrointestinal discomfort
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by using a specific blend of polydextrose (7.5-15 g/L) and galacto-oligosaccharide (2.5-7.5 g/L) in defined ratios, which alters the fermentation characteristics to reduce gas production while maintaining beneficial bacteria promotion

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent combines polydextrose and galacto-oligosaccharide in specific proportions to create a composite prebiotic system that leverages the complementary properties of both ingredients: polydextrose for low gas production and GOS for selective Bifidobacteria growth stimulation

Inventive Principle:
Principle #40Composite materials

2Reliability

If human milk oligosaccharides are replicated in formula, then SCFA profile similar to breast milk is achieved, but manufacturing complexity increases

Engineering Contradiction:
ImproveSCFA profile similarityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a simplified copy of human milk oligosaccharide functionality by using polydextrose and GOS blends that replicate the key metabolic outcome (SCFA profile) without attempting to reproduce the complex structure of HMOS

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent adjusts the concentration parameters of polydextrose and GOS to achieve target SCFA profiles (acetate, propionate, butyrate ratios) that match breast milk-fed infants, simplifying the manufacturing process compared to producing actual HMOS

Inventive Principle:
Principle #35Parameter changes

3Reliability

If fermentation rate is increased to promote bacteria growth, then beneficial bacteria population increases, but gas production increases

Engineering Contradiction:
Improvebacteria population growthVSAvoidgas production
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent modifies the fermentation parameters by selecting prebiotics with different fermentation rates: polydextrose ferments slowly producing minimal gas, while GOS ferments at a moderate rate supporting Bifidobacteria growth with acceptable gas levels

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

PDX and GOS effectively increase beneficial bacteria, optimize the SCFA profile, and reduce gastrointestinal discomfort in formula-fed infants, mimicking the benefits of breast milk oligosaccharides without causing adverse effects like bloating or diarrhea.

Implementation Method 1

These oligosaccharides are resistant to enzymatic digestion in the upper gastrointestinal tract and reach the colon intact, where they serve as substrates for colonic fermentation

Methodology Applied
Scientific EffectFermentation: Fermentation
