Solution Overview

Problem

Marking units made from partially crystalline plastics, such as polyamide, are difficult to print using thermal transfer and inkjet printing processes due to material properties that cause ink to easily be removed or scraped off, limiting their suitability for various printing processes.

Innovation Solution

The use of amorphous plastics, such as polycarbonate, acrylonitrile butadiene styrene, or polymethyl methacrylate, for producing marking mats, which offer improved printability and dimensional stability, allowing for successful printing with inkjet and thermal transfer printers without ink detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If partially crystalline plastics such as polyamide are used for producing marking units, then the marking units have good mechanical properties and dimensional stability, but they are difficult to print using thermal transfer and inkjet printing processes because ink easily detaches from the surface

Engineering Contradiction:
Improvemechanical properties and dimensional stabilityVSAvoidprintability
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the material parameter from semi-crystalline plastic to amorphous plastic, fundamentally altering the surface properties and molecular structure to enable better ink adhesion while maintaining dimensional stability required for printing processes

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent specifies amorphous plastics such as polycarbonate, acrylonitrile butadiene styrene, or polymethyl methacrylate as alternative materials that combine the necessary mechanical properties with improved surface characteristics for inkjet and thermal transfer printing compatibility

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If amorphous plastics are used for producing marking units, then printability is significantly improved and ink adhesion is stable, but the material selection is more limited compared to conventional semi-crystalline plastics

Engineering Contradiction:
ImproveprintabilityVSAvoidmaterial selection flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent identifies multiple amorphous plastic materials (polycarbonate, acrylonitrile butadiene styrene, polymethyl methacrylate) that can all serve the dual function of providing structural integrity and enabling superior printability across different printing processes, thus achieving universality in material performance

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If marking units are produced using injection molding process, then large numbers of marking units can be manufactured efficiently, but semi-crystalline plastics require higher processing temperatures and longer cycle times compared to amorphous plastics

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidprocessing energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by stationary object

Solution Approach 1:

The transition from semi-crystalline to amorphous plastics changes the processing parameters, allowing injection molding at lower temperatures and with shorter cycle times, thereby reducing energy consumption while maintaining high manufacturing efficiency

Inventive Principle:
Principle #35Parameter changes
