Solution Overview

Problem

There is a need for effective prevention and reduction of symptoms of viral infections, particularly for RNA viruses like Respiratory Syncytial virus (RSV), without relying on antiviral treatments, and in a manner that is compatible with a normal diet and does not compromise taste or health, while maintaining overall health and ease of implementation.

Innovation Solution

A composition comprising 2'-fucosyllactose (2'-FL) is administered orally to increase the production of short-chain fatty acids (SCFA), particularly acetate, in the distal colon, thereby enhancing protection against RNA-virus infections, preferably Group IV type viruses, by increasing acetate levels in circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antiviral treatments are used to prevent and reduce symptoms of viral infections, then the effectiveness of treatment is improved, but the complexity of treatment and potential adverse effects increase

Engineering Contradiction:
Improveeffectiveness of viral infection preventionVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses 2'-FL as an intermediary substance that indirectly prevents viral infections by modulating the gut microbiota and increasing SCFA production, rather than directly attacking the virus. This intermediary approach reduces treatment complexity while maintaining effectiveness, as 2'-FL naturally promotes beneficial bacterial growth which in turn produces antiviral compounds.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention enables the body's own immune system to fight viral infections by enhancing the production of short-chain fatty acids through 2'-FL supplementation. The gut microbiota performs the antiviral function autonomously by converting 2'-FL into SCFAs, eliminating the need for complex external antiviral interventions.

Inventive Principle:
Principle #25Self-service

2Reliability

If complex antiviral treatments are administered, then the protection against viral infections is improved, but the compatibility with normal diet and ease of implementation deteriorates

Engineering Contradiction:
Improveprotection against viral infectionsVSAvoidease of implementation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the approach from direct antiviral intervention to modifying dietary parameters by introducing 2'-FL. This simple dietary parameter change naturally leads to increased SCFA production and enhanced viral protection, making the solution easily implementable within normal dietary patterns without complex administration protocols.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If 2'-FL is administered to increase SCFA production, then the protection against RNA-virus infections is improved, but the quantity of substance required increases

Engineering Contradiction:
Improveprotection against RNA-virus infectionsVSAvoidamount of 2'-FL required
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent employs preliminary action by administering 2'-FL in advance to establish a reservoir of beneficial gut bacteria and their SCFA-producing capacity before viral exposure occurs. This preparatory supplementation ensures that when RNA viruses are encountered, the body already has enhanced antiviral defenses through pre-established high SCFA production, reducing the need for large quantities during acute infection.

Inventive Principle:
Principle #10Preliminary action
