Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If an inkjet receiver coating comprising silica and PVA is used, then printing quality is improved, but dust release occurs leading to equipment malfunctions and harmful effects

Engineering Contradiction:

Improveprinting qualityVSAvoiddust release

Core Design Contradiction:

Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters of the inkjet receiver coating by replacing silica and PVA with aluminum silicates (talc, clays, kaolin) as pigments. This parameter change maintains the coating's ability to receive inkjet printing while eliminating dust release problems associated with the original silica-PVA formulation.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses inexpensive aluminum silicate minerals (talc, clays, kaolin) instead of expensive silica and PVA. These natural pigments provide the necessary inkjet receiver functionality without creating dust release issues, offering a cost-effective and reliable alternative.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Manufacturing precision

If silica and PVA are used in inkjet receiver coating, then printing quality is enhanced, but production cost increases and resin penetration is affected

Engineering Contradiction:

Improveprinting qualityVSAvoidproduction cost

Core Design Contradiction:

Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent substitutes expensive silica and PVA with inexpensive natural aluminum silicates (talc, clays, kaolin). These natural pigments are abundant, low-cost materials that maintain inkjet receiver functionality while significantly reducing production costs.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the material composition parameters from synthetic silica-PVA to natural aluminum silicates, altering the chemical and physical properties of the coating to achieve both cost reduction and maintained printing quality.

Inventive Principle:

Principle #35Parameter changes

3Object-generated harmful factors

If an inkjet receiver coating with high binder content is used, then dust release is reduced, but resin penetration is hindered and production stability decreases

Engineering Contradiction:

Improvedust releaseVSAvoidproduction stability

Core Design Contradiction:

Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent extracts and eliminates the binder component from the inkjet receiver coating formulation. By using aluminum silicate pigments alone without binder, the coating achieves dust-free performance while maintaining resin penetration capability and production stability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The aluminum silicate pigments themselves serve as the intermediary material that provides both dust release control and resin penetration facilitation, eliminating the need for a separate binder component that would interfere with resin absorption.

Inventive Principle:

Principle #24Intermediary (Mediator)
