Solution Overview

Problem

Current yeast-based products for stimulating immune responses lack specificity and consistency in composition and outcome, failing to effectively enhance animal or human immune responses.

Innovation Solution

A composition comprising parietal polysaccharides from at least one Candida species combined with parietal polysaccharides from at least one different yeast species, which when combined, enhance immune responses even at low inclusion rates, with specific ratios and species such as Candida utilis and Saccharomyces cerevisiae being used.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If unspecific inactive yeast-based products are used to stimulate immune responses, then immune activation is claimed to occur through β-glucan/Dectin 1 pathways, but the products lack specificity and consistency in composition and outcome

Engineering Contradiction:
Improveconsistency of immune response outcomeVSAvoidspecificity of immune pathway activation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the immune stimulation function by identifying and isolating specific parietal polysaccharide components from yeast cell walls that selectively activate the β-glucan/Dectin 1 pathway, rather than relying on unspecific whole yeast products. This segmentation enables consistent and specific immune response activation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies parameter changes by defining specific compositional parameters of parietal polysaccharides (such as β-glucan content, molecular weight, and structural characteristics) that determine their ability to consistently activate Dectin 1 receptors, thereby transforming unspecific yeast products into specific immune stimulants with reliable outcomes.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If higher inclusion rates of yeast-based products are used to enhance immune stimulation, then stronger immune activation may be achieved, but the cost and complexity of the formulation increases

Engineering Contradiction:
Improveeffectiveness of immune response stimulationVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the active immunostimulatory parietal polysaccharide components from whole yeast cells, concentrating the beneficial effects into a purified form that requires lower inclusion rates in formulations. This extraction eliminates the need for complex whole yeast formulations while maintaining or enhancing immune stimulation effectiveness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a composite material consisting of purified parietal polysaccharides with defined compositional characteristics that combine multiple beneficial properties (specificity, consistency, potency) into a single formulation component, simplifying the overall formulation while improving reliability of immune response.

Inventive Principle:
Principle #40Composite materials
