Solution Overview

Problem

Current odor-neutralizing formulations either mask odors with fragrances, rely on acid/base neutralization, or use chemicals that pose health risks, failing to effectively eliminate unpleasant smells from sources like decomposition, excrement, and microorganisms without causing harm.

Innovation Solution

An aqueous solution of multivalent citrate salts, optionally combined with surfactants, chelating agents, and fragrances, is applied to saturate the odor source, allowing it to react and then absorb or dry, effectively reducing or eliminating odors without health risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If fragrance is introduced to mask unpleasant odor, then odor masking is achieved, but health problems occur for susceptible individuals who cannot recognize the original odor

Engineering Contradiction:
Improveodor masking effectivenessVSAvoidhealth risk for susceptible individuals
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of odorous compounds into a beneficial outcome by using oxidizing agents to chemically transform the odor-causing molecules into non-odorous substances. This approach eliminates the odor rather than masking it, thereby removing the health risk associated with fragrance masking while maintaining odor control effectiveness.

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

Solution Approach 2:

The patent changes the chemical parameters of the odorous compounds through oxidation reactions, transforming them from odorous to non-odorous states. By altering the chemical structure and properties of the odor-causing substances, the patent achieves effective odor elimination without introducing harmful masking fragrances.

Inventive Principle:
Principle #35Parameter changes

2Object-generated harmful factors

If chemicals are used to neutralize odors, then odor reduction is achieved, but health risks increase as concentrations rise from continued use or increased exposure

Engineering Contradiction:
Improveodor elimination effectivenessVSAvoidhealth risk from chemical exposure
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent uses oxidizing agents to fundamentally change the chemical parameters of odor-causing compounds, transforming them into non-odorous substances. This chemical transformation approach eliminates odors at the molecular level without requiring high concentrations of masking chemicals, thereby reducing health risks from continued chemical exposure.

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If agents that kill odor-producing microorganisms are used, then odor source elimination is achieved, but damage occurs to symbiotic microorganisms necessary for proper health upon inhalation

Engineering Contradiction:
Improvemicroorganism control effectivenessVSAvoiddamage to symbiotic microorganisms
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent converts the approach from killing microorganisms to chemically transforming the odor-causing compounds they produce. By using oxidizing agents to neutralize the odorous molecules directly, the patent eliminates the odor source without harming beneficial microorganisms, thereby maintaining health while achieving odor control.

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

Solution Approach 2:

The patent changes the chemical structure of odor-causing compounds through oxidation, transforming them into non-odorous substances. This approach addresses the odor problem at the molecular level rather than through microorganism elimination, preserving symbiotic microorganisms while effectively eliminating odors.

Inventive Principle:
Principle #35Parameter changes

4Object-generated harmful factors

If acid/base neutralization is used to eliminate odors, then some odor reduction is achieved, but a wide range of odors cannot be effectively eliminated

Engineering Contradiction:
Improveodor reduction for certain odorsVSAvoideffectiveness across different odor types
Core Design Contradiction:
Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent uses oxidizing agents to fundamentally change the chemical parameters of diverse odor-causing compounds through oxidation reactions. This approach is versatile and effective across a wide range of odor types including decomposition odors, excrement odors, and microorganism-related odors, overcoming the limitations of acid/base neutralization which only works for specific odor types.

Inventive Principle:
Principle #35Parameter changes
