Solution Overview

Problem

Current alcohol-based detergents used for COVID-19 virus removal cause skin irritation and have limited effectiveness in quickly dissolving the phospholipid membrane of the virus, leaving a risk of residual virus survival.

Innovation Solution

A detergent composition comprising 10-30% octylphenol ethoxylate, 0.1-5% 2-ethylhexyl alcohol ethoxylate, 0.1-5% ethylene oxide-propylene oxide block copolymer, and a balanced water mixture, with a neutral pH of 6.5-7, effectively binds and dissolves the phospholipid membrane of the corona virus without harming bacteria or causing skin irritation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If alcohol-based detergents are used to dissolve the phospholipid membrane of the virus, then the virus envelope is destroyed, but skin irritation occurs and the process takes too much time

Engineering Contradiction:
Improvevirus inactivation effectivenessVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the detergent by using a specific ternary combination of nonionic surfactants (octylphenol ethoxylate, 2-ethylhexyl alcohol ethoxylate, and ethylene oxide-propylene oxide block copolymer) with controlled HLB values and molecular structures. This parameter change allows the detergent to effectively dissolve the phospholipid membrane while being gentle on skin, resolving the contradiction between effectiveness and skin irritation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs a composite detergent system combining three different nonionic surfactants with complementary properties. The combination of octylphenol ethoxylate (strong solubilizing power), 2-ethylhexyl alcohol ethoxylate (gentle on skin), and ethylene oxide-propylene oxide block copolymer (emulsifying and stabilizing) creates a synergistic effect that achieves both high virus inactivation and skin friendliness.

Inventive Principle:
Principle #40Composite materials

2Reliability

If alcohol-based detergents are used to kill the virus, then the envelope is melted, but it takes a certain amount of time for the virus to die completely

Engineering Contradiction:
Improvecomplete virus eliminationVSAvoidtime required for virus death
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent modifies the chemical parameters of the detergent to enhance the speed of phospholipid membrane dissolution. The specific nonionic surfactant combination with optimized concentrations and molecular weights accelerates the disruption of the viral envelope, reducing the time required for complete virus inactivation while maintaining effectiveness.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If additional chemical components are added to alcohol-based detergents for moisturizing and sterilizing, then skin care functions are improved, but stability is compromised when irritation persists

Engineering Contradiction:
Improveskin care functionalityVSAvoidformulation stability under irritation conditions
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent changes the formulation parameters by using a ternary surfactant system with balanced HLB values and compatible molecular structures. This combination provides inherent skin moisturizing properties and formulation stability without requiring additional chemical additives, thus maintaining stability even when skin irritation occurs.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite detergent formulation where three nonionic surfactants work synergistically to provide both cleaning and skin care functions. The combination ensures formulation stability and skin compatibility without the need for additional stabilizing agents or moisturizers that could compromise stability under irritation conditions.

Inventive Principle:
Principle #40Composite materials
