Solution Overview

Problem

Current malodor control technologies often mask odors rather than effectively neutralize them, leading to consumer doubt about their efficacy and interference with the scent of perfumed or unperfumed products.

Innovation Solution

Development of malodor reduction compositions with a viscosity range of 1 mPa·s to 50,000 mPa·s that do not interfere with the scent of freshening compositions or treated surfaces, utilizing specific materials listed in Tables 1-6 to achieve genuine malodor neutralization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If scented perfumes are incorporated to mask malodors, then malodor control is improved, but the scent of the perfumed or unperfumed situs is interfered with

Engineering Contradiction:
Improvemalodor controlVSAvoidscent interference
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The invention extracts and removes the harmful masking effect from traditional malodor control approaches. By using malodor-neutralizing ingredients that chemically react with and eliminate malodor molecules rather than masking them with perfume, the harmful interference with desired scents is taken out of the system entirely.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention converts the harmful interaction between malodor control and scent preservation into a beneficial outcome. By using ingredients that selectively neutralize malodors without affecting desired scents, the system simultaneously achieves effective malodor control and scent preservation, turning the previous trade-off into a dual benefit.

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

2Object-affected harmful factors

If traditional malodor control technologies are used, then malodor reduction is achieved, but consumer confidence is reduced due to delayed noticeable effect

Engineering Contradiction:
Improvemalodor reductionVSAvoidtime for noticeable effect
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The invention applies preliminary action by using malodor-neutralizing ingredients that provide immediate neutralization upon contact with malodor molecules. The composition is formulated to act quickly without requiring extended contact time, giving consumers immediate visible results that build confidence.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the kinetic parameters of malodor neutralization by selecting ingredients and formulations that react rapidly with malodor molecules. By optimizing the reactivity and concentration of active ingredients, the time required for noticeable malodor reduction is significantly shortened.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If malodor control technologies are used, then malodor blocking is improved, but the palette of available scents is limited

Engineering Contradiction:
Improvemalodor blockingVSAvoidscent variety
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The invention introduces an intermediary mechanism that selectively interacts with malodor molecules while leaving desired scent molecules unaffected. The malodor-neutralizing ingredients act as intermediaries that target specifically at malodor compounds through chemical reactions, allowing desired scents to pass through unchanged.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention applies local quality by creating selective interaction zones within the composition. Different ingredients are formulated to target specific malodor types (amine-based, thiol-based, carboxylic acid-based, etc.) while maintaining compatibility with various desired scents, allowing the system to handle diverse malodor-scent combinations.

Inventive Principle:
Principle #3Local quality
