Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If fat-soluble vitamins are used in feed additives, then nutritional value is improved, but stability deteriorates due to oxidation

Engineering Contradiction:

Improvefat-soluble vitamin contentVSAvoidstability against oxidation

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The fat-soluble vitamin is encapsulated within a matrix formed by lignosulfonate and hexose-dimers/polymers. This nested structure places the vitamin (inner object) inside the protective matrix (outer object), shielding it from oxidation while maintaining its nutritional function in feed additives.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention uses a composite matrix system combining lignosulfonate (a phenolic polymer) with hexose-dimers, modified hexose-dimers, hexose-oligomers, or hexose-polymers. This composite material provides enhanced protective properties against oxidation compared to single materials, while encapsulating the fat-soluble vitamin.

Inventive Principle:

Principle #40Composite materials

2Reliability

If encapsulation matrix is formed to protect vitamin, then stability is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvestability against oxidationVSAvoidformulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention optimizes specific parameter ranges: lignosulfonate at 5-55 wt%, hexose-dimers/oligomers/polymers at ≥10 wt%, and fat-soluble vitamin at 1-40 wt%. By controlling these compositional parameters, the formulation achieves effective encapsulation and stability without excessive complexity in the manufacturing process.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If conventional antioxidants are used, then stability is improved, but harmful factors increase due to ethoxyquin and BHT

Engineering Contradiction:

Improvestability against oxidationVSAvoidpresence of ethoxyquin and BHT

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts or removes harmful conventional antioxidants (ethoxyquin and BHT) from the feed additive formulation. Instead, it relies on the protective encapsulation matrix of lignosulfonate and hexose-polymers, which provides oxidation protection without introducing harmful synthetic antioxidants.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The lignosulfonate-hexose polymer matrix acts as an intermediary protective layer between the fat-soluble vitamin and oxidative environmental factors. This intermediary structure provides protection without requiring direct contact with harmful antioxidants.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Loss of substance

If process loss is reduced, then vitamin efficiency is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Improveprocess loss of vitaminVSAvoidencapsulation precision

Core Design Contradiction:

Loss of substanceVSManufacturing precision

Solution Approach 1:

By optimizing the formulation parameters (lignosulfonate 5-55 wt%, hexose-dimers/oligomers/polymers ≥10 wt%, vitamin 1-40 wt%) and processing conditions, the invention achieves effective encapsulation that minimizes vitamin loss during manufacturing while maintaining feasible manufacturing precision requirements.
