Solution Overview

Problem

Current sanitizing and disinfecting agents are inadequate for effectively decontaminating both living tissues and inanimate objects from chemical warfare agents, toxins, infectious agents, and conformationally altered prions, as they lack sporicidal action, are not food-grade, and can be toxic or corrosive, making them unsuitable for use on skin, food products, and healthcare settings.

Innovation Solution

Aqueous compositions comprising a mixture of lower alkanols (1-6 carbon atoms) and fatty acid derivatives, such as alkali or alkaline earth metal salts or glycerides, at a pH of 14 or above, which are applied to materials to sanitize and decontaminate, providing both germicidal and sporicidal activity while being safe for human use and the environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard disinfectants (bleach, powder detergent, abrasive powder) are used for hard surface disinfection, then disinfection capability is achieved, but they are toxic or corrosive and unsuitable for use on skin and food products

Engineering Contradiction:
Improvedisinfection capabilityVSAvoidtoxicity and corrosiveness
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the disinfectant by using food-grade ingredients (isopropyl alcohol, hydrogen peroxide, citric acid, sodium citrate) at controlled concentrations. The pH is adjusted to 6.5-7.5 to match skin pH, eliminating corrosiveness while maintaining disinfection capability through the synergistic action of these components

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite disinfectant formulation combining multiple food-grade ingredients (alcohol, hydrogen peroxide, citric acid, sodium citrate) that work synergistically. This composite approach provides broad-spectrum disinfection while ensuring safety for skin and food contact surfaces

Inventive Principle:
Principle #40Composite materials

2Reliability

If alcohol-based hand sanitizers are used to reduce germ transmission, then antimicrobial activity is improved, but they lack sporicidal action and cannot penetrate protein-rich materials

Engineering Contradiction:
Improveantimicrobial activityVSAvoidsporicidal action and penetration capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent merges alcohol-based antimicrobial action with hydrogen peroxide sporicidal activity and citric acid/protein-denaturing capabilities. This combination allows the formulation to achieve sporicidal action, penetrate protein-rich materials, and maintain broad-spectrum antimicrobial activity that no single ingredient could provide alone

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If plain soap is used for hand washing, then ease of operation is maintained, but it has minimal antimicrobial activity and can become contaminated with pathogens

Engineering Contradiction:
Improvehand washing simplicityVSAvoidantimicrobial activity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent creates a self-disinfecting hand wash formulation where the ingredients (alcohol, hydrogen peroxide, citric acid, sodium citrate) work together to provide antimicrobial activity without requiring separate disinfection steps. The formulation maintains simplicity of use like plain soap while inherently preventing contamination through its antimicrobial components

Inventive Principle:
Principle #25Self-service
