Solution Overview

Problem

Existing disinfectants used for eliminating harmful germs and viruses are often effective but pose safety concerns, necessitating stringent guidelines and careful use, while alternative methods like heat sterilization or radiation sterilization may be less desirable.

Innovation Solution

A cleaning composition is formulated by coating a granular absorbent material with a biocide and mixing it with a sanitation agent, such as an anionic surfactant, to create a multi-phase product that disrupts viral proteins and envelopes, providing a safe and effective means to decontaminate surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical disinfectants are used to eliminate harmful germs and viruses, then effectiveness in decontamination is improved, but safety concerns increase requiring stringent guidelines

Engineering Contradiction:

Improvedecontamination effectivenessVSAvoidsafety concerns

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of disinfectants by using diluted concentrations combined with extended contact times. Instead of using high concentrations of harsh chemicals, the invention uses lower concentrations (e.g., 0.1% to 10% solutions) applied for prolonged periods (e.g., 10 minutes to several hours), thereby achieving effective decontamination while reducing safety hazards and corrosiveness

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces absorbent materials (such as cellulose, silica gel, or activated carbon) as intermediaries that deliver the disinfectant to the contaminated surface. These materials serve as carriers that control the release of the active ingredient, extending contact time while reducing the need for high concentrations of harmful chemicals

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If heat sterilization or radiation sterilization is used as alternative methods, then safety is improved, but desirability decreases due to complexity or resource requirements

Engineering Contradiction:

ImprovesafetyVSAvoidpractical applicability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent replaces mechanical/physical sterilization methods (heat, radiation) with chemical disinfection methods. Instead of using autoclaves, ovens, or radiation equipment, the invention uses chemical solutions that can be easily applied to surfaces, making the process more adaptable to various environments including homes, offices, and public spaces without requiring specialized equipment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If stringent guidelines are placed on chemical disinfectant compositions, then safety is improved, but ease of operation decreases

Engineering Contradiction:

ImprovesafetyVSAvoiduser convenience

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent designs disinfectant compositions that are self-regulating in terms of safety. The formulations use inherently safer chemicals at diluted concentrations, and the absorbent materials control the release rate, creating a system that is safe to use without requiring extensive training or adherence to complex safety protocols. The product essentially protects the user through its design

Inventive Principle:

Principle #25Self-service

AI summary

A method for formulating a cleaning composition contains the step of coating a granular absorbent material with a coating agent to produce a coated absorbent material and mixing the coated absorbent material with a sanitation agent, wherein the coated absorbent material absorbs the sanitation agent to form the cleaning composition. The resulting cleaning composition may be used for cleaning up pathogens or hazardous materials. The cleaning composition may also functions as a liquefiable dry cleaning powder for public areas in response to bodily fluid incidents. A coating method of a non-toxic bio static film on a high surface area solid is disclosed.
