Solution Overview

Problem

Cereal grains, including wheat, oats, barley, and rice, are known to cause allergic reactions and atopic dermatitis, particularly in children, due to their protein content, and existing solutions like hydrolyzed wheat proteins can exacerbate allergies by revealing new antigen sites.

Innovation Solution

An extract from the aerial parts of oats harvested before ear emergence, rich in flavonoids and avenacosides, is used to create a hypoallergenic dermatological composition that minimizes allergic reactions by avoiding cross-reactions with cereal grain proteins, with a protein content below 0.3 ppm, obtained through organic solvent extraction and characterized by high pressure liquid chromatography.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cereal grain proteins are used in dermatological compositions, then beneficial dermatological effects are achieved, but allergic reactions and atopic dermatitis are triggered

Engineering Contradiction:
Improvedermatological efficacyVSAvoidallergic reactions
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and isolates specific avenacosides (A and B) from oat grains through organic solvent extraction and chromatography purification, separating the beneficial dermatological components from the allergenic proteins. This extraction principle allows obtaining a purified extract that maintains therapeutic effects while eliminating cross-reactivity with cereal grain allergens.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the chemical composition parameters by controlling the extraction process to achieve specific concentrations of avenacosides (0.1-10 mg/mL) while reducing protein content below detectable levels. This parameter optimization ensures the composition provides dermatological benefits without triggering allergic responses in sensitized individuals.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If hydrolyzed wheat proteins are used to alleviate allergies, then protein sensitivity is reduced, but new antigen sites are revealed that exacerbate allergies

Engineering Contradiction:
Improveprotein sensitivityVSAvoidnew antigen sites
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

Instead of using hydrolyzed proteins that create new allergens, the patent utilizes intact avenacosides from oats that have demonstrated anti-inflammatory and immunomodulatory properties. This approach converts the potential harm of protein exposure into a beneficial effect by using non-allergenic steroidal saponins that actively reduce inflammation and modulate immune responses without creating new antigenic sites.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of operation

If cereal extracts are used in cosmetics, then skin benefits are provided, but cross-reactions occur in persons sensitized to cereal grains

Engineering Contradiction:
Improvecosmetic benefitsVSAvoidcross-reactions
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent uses avenacosides as intermediary compounds that provide the desired dermatological effects without directly interacting with cereal grain allergens. These steroidal saponins act as mediators that deliver anti-inflammatory and skin-protective benefits while maintaining immunological tolerance in sensitized individuals, effectively bridging the gap between cosmetic efficacy and allergen avoidance.

Inventive Principle:
Principle #24Intermediary (Mediator)
