Solution Overview

Problem

Water-soluble cleaning pouches generate malodors due to film material impurities, which accumulate in the packaging container and negatively impact consumer acceptance, while traditional perfuming methods are not effective in masking these odors without being overpowering.

Innovation Solution

A detergent pack with a water-soluble cleaning pouch and a packaging container featuring a hinged lid and an internal adhesive strip containing an aldehyde-comprising perfume, which slowly releases a pleasant scent to counteract malodors and maintain consumer appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water-soluble cleaning pouches are stored in packaging containers, then moisture protection is improved, but malodour accumulation occurs in the headspace

Engineering Contradiction:
Improvemoisture protectionVSAvoidmalodour accumulation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

An adhesive strip containing aldehyde-comprising perfume is applied to the internal wall of the packaging container. This strip acts as an intermediary that releases perfume slowly into the headspace, counteracting the malodours generated by the water-soluble pouch without requiring strong perfumes that would be overpowering.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adhesive strip with perfume is pre-applied to the packaging container before the pouch is inserted. This preliminary action ensures that the perfume is already present in the headspace to counteract any malodours that may develop during storage, addressing the problem before it occurs.

Inventive Principle:
Principle #10Preliminary action

2Object-generated harmful factors

If strong perfumes are used to mask malodours, then odour masking is improved, but consumer acceptance deteriorates due to overpowering scent

Engineering Contradiction:
Improvemalodour maskingVSAvoidconsumer acceptance
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The invention changes the parameters of perfume delivery by using an adhesive strip that releases perfume slowly over time, rather than using strong perfumes that release all at once. This controlled release mechanism provides adequate malodour masking while maintaining consumer acceptance through a pleasant, non-overpowering scent.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The adhesive strip provides periodic or sustained release of perfume into the headspace, creating a continuous but gentle scent presence that counteracts malodours without becoming overpowering. This periodic action maintains a balanced olfactory environment in the packaging container.

Inventive Principle:
Principle #19Periodic action

3Object-generated harmful factors

If perfume is released from the cleaning composition into the headspace, then pleasant smell is improved, but perfume transfer is blocked by water-soluble film

Engineering Contradiction:
Improvepleasant smellVSAvoidperfume transfer
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

Since the water-soluble film blocks perfume transfer from the pouch, an intermediary adhesive strip is applied to the container's internal wall. This strip contains the perfume needed to create a pleasant smell in the headspace, bypassing the barrier created by the impermeable film while still achieving the desired sensory effect.

Inventive Principle:
Principle #24Intermediary (Mediator)
