Innovation Solution

The use of a UV curable material applied via a UV curing method, combined with electrical vibration and physical pressure to permeate ink into concrete surfaces, and a printing apparatus that integrates ink spraying and coating agent application for simultaneous printing and surface reinforcement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional printing methods are used on concrete surfaces, then printing can be performed, but the print clarity and durability are insufficient

Engineering Contradiction:
Improveprint clarityVSAvoidprint durability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The invention changes the chemical and physical parameters of the concrete surface by applying a permeation primer that opens pores and a coating primer that creates a bonding layer, transforming the surface properties to enable UV ink adhesion and penetration, thereby achieving both clarity and durability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses a composite printing system combining permeation primer, coating primer, UV curable ink, and UV gloss oil in sequential layers, where each material serves a specific function: pore penetration, surface bonding, color deposition, and protective coating, collectively achieving durable and clear prints

Inventive Principle:
Principle #40Composite materials

2Duration of action of stationary object

If conventional printing methods are used on concrete surfaces, then printing can be performed, but the prints are damaged over time

Engineering Contradiction:
Improveprint lifespanVSAvoidprint integrity
Core Design Contradiction:
Duration of action of stationary objectVSReliability

Solution Approach 1:

The invention performs preliminary surface preparation by applying permeation primer and coating primer before the main UV ink printing, creating a prepared surface that ensures long-term adhesion and prevents future damage, thereby extending print lifespan while maintaining integrity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention applies a UV gloss oil coating after printing that provides a protective cushioning layer over the printed surface, shielding the UV ink from environmental damage and physical wear, thus preserving print integrity over time

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If UV curable material is used with UV curing method, then print durability is improved, but additional processing steps are required

Engineering Contradiction:

The invention merges multiple functions into integrated processing units: the UV curing lamp combines drying and curing functions, the coating agent application means combines printing and protective coating in one operation, reducing overall process complexity while maintaining durability

Inventive Principle:
Principle #5Merging (Combining)

4Manufacturing precision

If surface preprocessing is performed on concrete, then UV ink adhesion is improved, but construction time increases

Engineering Contradiction:
Improveink adhesionVSAvoidconstruction time
Core Design Contradiction:
