Solution Overview

Problem

Melamine foam cleaning implements face challenges in maintaining effective odor control and longevity during repeated use on hard surfaces without the buildup of malodors, especially when used with food or drink soils.

Innovation Solution

A melamine foam cleaning implement with a thickness of at least 5 mm, incorporating a perfume source that is evenly distributed throughout the foam or within a supporting material, using matrix polymer-assisted delivery compositions and encapsulated perfumes to ensure consistent fragrance release and extended use without malodor buildup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If melamine foam cleaning implements are used repeatedly on hard surfaces with food or drink soils, then cleaning performance is maintained, but malodour builds up due to repeated wetting and soil accumulation

Engineering Contradiction:
Improveworking lifeVSAvoidmalodour buildup
Core Design Contradiction:
Duration of action of moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of soil and moisture accumulation (which causes malodour) into a beneficial effect by incorporating perfume sources that release fragrance during repeated wetting and use. The perfume masks and neutralizes the malodour while the foam continues to clean, transforming the problematic repeated use into an opportunity for continuous fragrance delivery.

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

Solution Approach 2:

The patent introduces perfume sources as an intermediary substance between the user and the cleaning implement. This intermediary (perfume) mediates the interaction by releasing fragrance that counteracts the malodour generated during cleaning, allowing the foam to be used repeatedly without the harmful odor buildup affecting the user experience.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If thin melamine foam (less than 1 mm) is used in cleaning towelettes, then the implement is suitable for gentle cleaning, but it cannot effectively remove dried on or stubborn soils on uneven surfaces

Engineering Contradiction:
Improvesuitability for gentle cleaningVSAvoideffectiveness on stubborn soils
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent creates a composite cleaning implement by combining melamine foam with supporting material layers. This composite structure integrates the gentle cleaning properties of thin melamine foam with the mechanical strength and durability of supporting materials, enabling the implement to effectively remove stubborn soils on uneven surfaces while maintaining ease of operation.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent segments the cleaning implement into multiple functional layers: melamine foam layers for cleaning action and supporting material layers for structural integrity. This segmentation allows each layer to perform its specific function optimally, with the foam providing gentle cleaning and the support material providing the necessary strength for tackling stubborn soils.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If melamine foam cleaning implements are used without separate cleaning adjuncts, then high performance cleaning is achieved, but there is risk of malodour buildup from repeated wetting

Engineering Contradiction:
Improvesimplicity of useVSAvoidmalodour
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The patent merges multiple functions into a single cleaning implement: the melamine foam provides cleaning action, while integrated perfume sources provide odor control. This merging eliminates the need for separate cleaning adjuncts or perfumes, maintaining simplicity of use while preventing malodour buildup through the combined cleaning and fragrance-delivering functions.

Inventive Principle:
Principle #5Merging (Combining)
