Solution Overview

Problem

Current antiviral agents for influenza virus, such as amantadine and rimantadine, are ineffective against serotype B and can generate mutant viruses resistant to their action, while newer agents like oseltamivir have side effects and may lead to resistant strains, highlighting the need for a safe, natural alternative to enhance immunity and treat influenza virus infections effectively.

Innovation Solution

A herbal extract combining Epimedium koreanum, Lonicerae Flos, Polygala Root, and Saussurea lappa, along with other medicinal herbs, is extracted and formulated for use in preventing and treating influenza virus infections, offering a natural and safe option effective against various serotypes including H1N1, H5N1, and H7N1.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antiviral agents like amantadine and rimantadine are used to treat influenza virus, then the virus proliferation is suppressed, but mutant viruses resistant to the drug are generated and the agents are ineffective against serotype B

Engineering Contradiction:
Improveeffectiveness against influenza virusVSAvoiddrug-resistant mutant viruses
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies this principle by using plant extracts that naturally occur in the environment to combat viral infections. Instead of synthesizing complex chemical antivirals that select for resistance, the invention utilizes phytochemicals from plants like Epimedium, Lonicera, Polygala, and Saussurea that have demonstrated broad-spectrum antiviral activity without inducing resistance, effectively converting natural plant compounds into therapeutic agents.

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

Solution Approach 2:

The patent combines multiple plant extracts (Epimedium koreanum, Lonicerae Flos, Polygala Root, Saussurea lappa, and other medicinal herbs) into a composite herbal formulation. This composite approach leverages the synergistic effects of different phytochemicals to achieve broad-spectrum antiviral activity against multiple influenza serotypes while reducing the likelihood of resistance development through multi-target action.

Inventive Principle:
Principle #40Composite materials

2Reliability

If newer antiviral agents like oseltamivir are used to treat influenza virus, then the virus proliferation is inhibited, but side effects occur and resistant strains may develop

Engineering Contradiction:
Improvevirus proliferation inhibitionVSAvoidside effects and resistant strains
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes naturally occurring plant compounds that can be replenished through agriculture and natural sources, replacing expensive synthetic antivirals with renewable phytochemical resources. The herbal formulation provides a sustainable, cost-effective alternative that reduces reliance on pharmaceutical industries and minimizes environmental and health burdens associated with synthetic drug production and resistance management.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Object-affected harmful factors

If a natural herbal extract is used as an alternative to synthetic antivirals, then safety and low toxicity are improved, but the need to demonstrate effectiveness against various influenza serotypes must be proven

Engineering Contradiction:
Improvetoxicity and safety profileVSAvoideffectiveness against influenza serotypes
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent demonstrates that the herbal formulation possesses universal antiviral activity against multiple influenza serotypes (H1N1, H3N2, H5N1, H7N1, and others) through a single multi-component formulation. The combination of phytochemicals from different plant sources provides broad-spectrum coverage, making the treatment universally applicable across various viral strains without requiring separate medications for different serotypes.

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