Solution Overview

Problem

Current cleaning and disinfecting solutions are inadequate for effectively eliminating a wide range of microorganisms, odors, and toxic materials from various environments without damaging surfaces, and they often require long disinfection times and are unstable.

Innovation Solution

A two-component formulation comprising an aqueous alkaline solution with a non-ionic surfactant, quaternary ammonium compounds, and triamine, combined with an aqueous acidic hydrogen peroxide solution, which is mixed just before application, providing rapid and synergistic antimicrobial action while decomposing or neutralizing harmful substances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cleaning and disinfecting solutions are used, then some level of cleaning is achieved, but they fail to effectively eliminate a wide range of microorganisms, odors, and toxic materials while often damaging surfaces

Engineering Contradiction:
Improveeffectiveness against microorganisms and contaminantsVSAvoidsurface damage and corrosive effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The disinfectant is divided into two separate components that are mixed immediately before use. Component 1 contains the alkaline solution with surfactants and quaternary ammonium compounds, while Component 2 contains the acidic hydrogen peroxide solution. This segmentation allows each component to be optimized for its specific function without the stability issues of pre-mixed formulations, achieving high effectiveness against microorganisms and contaminants while preventing surface damage through controlled activation of the hydrogen peroxide only at the moment of application.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The formulation utilizes changes in pH and chemical reactivity parameters. Component 1 is maintained at alkaline pH (8-10) for stability and cleaning effectiveness, while Component 2 contains acidic hydrogen peroxide solution. When mixed, the pH neutralizes and the hydrogen peroxide decomposes into water and oxygen, transforming from a potentially damaging oxidizing agent into a safe byproduct. This parameter change allows the system to achieve high reliability in eliminating contaminants while eliminating harmful effects on surfaces.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If strong disinfectants are used to kill microorganisms rapidly, then disinfection speed improves, but the formulations become unstable and require long disinfection times

Engineering Contradiction:
Improvedisinfection speedVSAvoidformulation stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The formulation is segmented into two stable components that can be stored separately for extended periods. Component 1 (alkaline solution with surfactants and quaternary ammonium compounds) and Component 2 (acidic hydrogen peroxide solution) remain stable in their separate states. The unstable, highly reactive disinfecting action is only generated when the components are mixed immediately before application, providing both formulation stability during storage and rapid disinfection action when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The surfactants and quaternary ammonium compounds in Component 1 perform preliminary cleaning and surface preparation actions before the hydrogen peroxide from Component 2 is activated. This preliminary action removes organic matter and prepares the surface, allowing the subsequently activated hydrogen peroxide to work more efficiently and rapidly on microorganisms, thereby increasing disinfection speed without compromising formulation stability during storage.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multi-functional formulations are used to address various contaminants, then versatility improves, but the formulations become complex and difficult to manufacture

Engineering Contradiction:
Improverange of contaminants eliminatedVSAvoidformulation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The multi-functional disinfectant is segmented into two components, each with a specific functional focus. Component 1 contains cleaning agents (surfactants) and antimicrobial agents (quaternary ammonium compounds), while Component 2 contains the oxidizing agent (hydrogen peroxide). This segmentation simplifies manufacturing by allowing each component to be produced and stabilized separately using straightforward formulations, avoiding the complexity of creating a single stable multi-component mixture. The versatility against various contaminants (microorganisms, odors, toxic materials) is achieved through the synergistic combination of these simpler, easier-to-manufacture components when mixed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The two-component system achieves universality in contaminant elimination through the complementary actions of its components. The quaternary ammonium compounds provide broad-spectrum antimicrobial activity, the surfactants handle organic contaminants and odors, and the hydrogen peroxide provides oxidation capability for toxic materials and spores. This multi-functionality is achieved through a relatively simple two-component structure that can be manufactured easily, with each component containing specific ingredients tailored to particular functions rather than attempting to include all functions in a single complex formulation.

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