Solution Overview

Problem

Existing infant formula powders face challenges with nutritional and microbiological properties, particularly in achieving improved flow properties to prevent lumping and cohesion during dispensing, while adhering to regulatory nutrient requirements and avoiding the use of non-approved ingredients.

Innovation Solution

Incorporation of micronized lactose or lactose microcrystals with a size less than 10 micrometers to enhance the flowability of infant formula powder compositions, maintaining compliance with regulatory standards by using an approved nutrient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional infant formula powder is used, then nutritional requirements are met, but flow properties are poor causing lumping and cohesion during dispensing

Engineering Contradiction:
Improveflow propertiesVSAvoidlumping and cohesion
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies parameter changes by modifying the particle size of lactose from conventional larger particles to micronized particles with D50 between 4-10 micrometers. This parameter change in particle size improves flow properties and prevents lumping while maintaining nutritional integrity and regulatory compliance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite powder formulation combining micronized lactose with other infant formula ingredients (proteins, fats, vitamins, minerals). This composite approach leverages the excellent flow properties of micronized lactose to improve overall mixture flowability without compromising nutritional requirements.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If free-flowing agents are added to improve flow properties, then dispensing becomes easier, but non-approved ingredients are introduced violating regulatory standards

Engineering Contradiction:
Improvedispensing easeVSAvoiduse of non-approved ingredients
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent applies self-service by using micronized lactose, which is already an essential nutrient component of infant formula, to provide the free-flowing effect. The lactose serves dual purposes: maintaining nutritional value and improving flow properties, eliminating the need for separate free-flowing agents.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent demonstrates multi-functionality by having micronized lactose serve multiple functions simultaneously: it provides nutritional value as a carbohydrate source, acts as a flow promoter, and prevents lumping during dispensing and storage. This eliminates the need for additional specialized additives.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If spoon or scoop dispensing is used, then dosing is possible, but user convenience deteriorates due to hand contact and spoon contamination

Engineering Contradiction:
Improvedosing accuracyVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies parameter changes in particle size (micronized lactose with D50 4-10 micrometers) that enable the powder to flow freely and be dispensed cleanly without requiring spoons or scoops. The improved flow properties allow for easy pouring and dosing while preventing powder adhesion to dispensing tools.

Inventive Principle:
Principle #35Parameter changes
