Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional solid pigment preparations are used, then they are dispersible in either aqueous or solvent-borne media, but they require multiple different formulations for different application media leading to inconsistent color characteristics

Engineering Contradiction:

Improveuniversal dispersibility in water- and solvent-based systemsVSAvoidconsistency of color characteristics

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies universality by designing a single solid pigment preparation formulation containing both anionic and nonionic surfactants that can function effectively in both aqueous and solvent-borne media. The composition includes pigment particles (5-50 wt%), anionic surfactant (1-20 wt%), nonionic surfactant (1-20 wt%), and optional additives (0-10 wt%), creating a multi-functional preparation that adapts to different application media while maintaining consistent color properties.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent employs composite materials by combining multiple surfactant types (anionic and nonionic) with the pigment particles to create a composite solid pigment preparation. This composite structure allows the preparation to interact with both polar (aqueous) and non-polar (solvent-borne) media effectively, ensuring universal dispersibility and consistent color characteristics across different application systems.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If liquid pigment preparations are dried to obtain solid preparations, then handling is easier and actives content is higher, but the desired dispersibility and stability properties cannot be obtained

Engineering Contradiction:

Improvehandling convenience and actives contentVSAvoiddispersibility and stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by incorporating the surfactant system into the solid pigment preparation during the manufacturing process, before the pigment needs to be dispersed in application media. The surfactants are pre-bound to the pigment particles in the solid form, so when the pigment is later used, the dispersibility and stability properties are already established, eliminating the need for separate liquid preparation steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs parameter changes by transforming the pigment preparation from liquid to solid form while maintaining critical performance parameters through the use of surfactants. The solid preparation retains the dispersibility and stability characteristics of liquid preparations through the incorporation of anionic and nonionic surfactants, allowing it to achieve both ease of handling (solid form) and reliable performance (dispersibility and stability).

Inventive Principle:

Principle #35Parameter changes
