VSEngineering Contradiction Analysis

1Speed

If conventional powder detergent formulations are used, then the detergent is easy to store and transport, but it suffers from caking and slow dissolution rates

Engineering Contradiction:
Improvedissolution rateVSAvoidcaking resistance
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent changes the physical and chemical parameters of the detergent formulation by using specific surfactant combinations (anionic, nonionic, and amphoteric surfactants), controlled moisture content (5-15%), and specific additive ratios to prevent caking and enhance dissolution rate. The sodium C14-16 olefin sulfonate content is optimized at 45-55% to achieve fast dissolution without caking.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs a composite detergent system combining multiple surfactant types (anionic, nonionic, amphoteric), fillers (sodium sulfate, sodium carbonate), and functional additives (preservatives, chelating agents, enzymes). This composite approach creates synergistic effects that simultaneously improve dissolution rate and prevent caking through balanced formulation chemistry.

Principle #40Composite materials

2Loss of time

If the detergent dissolves quickly, then user convenience is improved, but cleaning effectiveness may be compromised

Engineering Contradiction:
Improvedissolution timeVSAvoidcleaning capability
Core Design Contradiction:
Loss of timeVSStrength

Solution Approach 1:

The patent optimizes the concentration and type of surfactants to achieve both fast dissolution and strong cleaning. The specific ratio of anionic to nonionic to amphoteric surfactants, along with controlled filler content, ensures rapid water penetration and dissolution while maintaining sufficient surfactant concentration for effective cleaning performance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The multi-component surfactant system provides both rapid dissolution (through hydrophilic components) and strong cleaning capability (through amphiphilic surfactant molecules that effectively remove oils and stains). The composite formulation includes enzymes and chelating agents that enhance cleaning while the overall composition ensures fast dissolution.

Inventive Principle:
Principle #40Composite materials
