Solution Overview

Problem

Cleaning compositions in tablet form require user handling, which can lead to disintegration and exposure to harmful ingredients, and liquid or gel formulations in water-soluble sachets face instability and reduced storage stability due to water sensitivity, leading to quality issues and increased manufacturing costs.

Innovation Solution

A composition with hydrolytically unstable components is stabilized using a non-aqueous carrier system comprising mineral oil, a gelling agent, and an emulsifying agent, allowing for a single compartment dosage system that maintains stability and prevents premature activation of bleaching agents until use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cleaning composition is provided in liquid or gel form in water soluble sachet, then aesthetic appeal and ease of handling are improved, but storage stability deteriorates due to hydrolytic instability of components

Engineering Contradiction:
Improveease of handlingVSAvoidstorage stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent changes the physical state parameter of the cleaning composition from liquid/gel to powder form, and changes the water content parameter from high (aqueous) to low (anhydrous or minimal water), thereby improving storage stability while maintaining ease of handling through the sachet delivery system

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite material formulations combining multiple powder components (surfactants, builders, enzymes, bleaching agents) that are stable in anhydrous conditions, creating a stable mixture that maintains effectiveness without requiring water for storage stability

Inventive Principle:
Principle #40Composite materials

2Reliability

If water sensitive components are encapsulated in hydrophobic coating, then storage stability is improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvestorage stabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts water from the formulation entirely, using anhydrous or minimal-water compositions that do not require encapsulation or hydrophobic coatings for protection, thereby simplifying manufacturing while maintaining storage stability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of protecting water-sensitive components from water through encapsulation, the patent inverts the approach by formulating components that are inherently stable without water or that function better in anhydrous conditions, eliminating the need for protective coatings

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If encapsulation is used to protect water sensitive components, then storage stability is improved, but performance is reduced due to removal of encapsulating medium requirement

Engineering Contradiction:
Improvestorage stabilityVSAvoidperformance reduction
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the water content parameter to anhydrous or minimal-water conditions, allowing components to remain accessible and active without requiring removal of encapsulating media, thereby maintaining both storage stability and performance

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If structured system with highly viscous matrix is used to reduce sedimentation, then physical instability is reduced, but separation still occurs on prolonged storage

Engineering Contradiction:
Improvephysical stabilityVSAvoidlong-term stability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent changes the consistency parameter from highly viscous to powder form, and eliminates the need for suspension stability by using dry powder components that do not sediment or separate, ensuring long-term stability without requiring viscous matrices

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts water from the formulation, eliminating the liquid medium that causes sedimentation and separation, thereby achieving long-term stability in powder form without requiring viscous matrices or suspension mechanisms

Inventive Principle:
Principle #2Taking out (Extraction)
