Solution Overview

Problem

Conventional methods for producing patterned linoleum floor coverings are limited by restrictive design options, low production flexibility, and the inability to achieve high-resolution or photorealistic designs due to the direct mixing and rolling process, which also results in insufficient adhesion and environmental concerns with halogen-containing materials.

Innovation Solution

A linoleum-based printed sheet material comprising a base layer, a primer layer, and a highly resistant top layer with inorganic particles, allowing for decoupling of color and design production, enabling flexible and high-resolution digital printing with renewable materials and improved adhesion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If colored mixed masses are poured directly into a calender gap and rolled out, then production process is simple, but longitudinal structures result and design options are severely restricted

Engineering Contradiction:
Improveproduction process simplicityVSAvoiddesign options
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent divides the production process into separate stages: base layer production without colorants, followed by separate printing of color designs. This segmentation allows the base layer to be produced simply while the design layer provides unlimited design options through digital printing techniques.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base layer is produced in advance without colorants, allowing it to be ready for subsequent printing. This preliminary production of the neutral base enables flexible design changes and high-resolution printing without reproducing the entire linoleum sheet.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If scattering technique is used for color designs, then special color patterns can be achieved, but effort is no longer justifiable and quick pattern changes are not allowed

Engineering Contradiction:
Improvespecial color designsVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The manual scattering technique is replaced with digital printing systems that use digital files to control color application. This substitution eliminates manual effort while enabling rapid pattern changes through software updates, maintaining design versatility while dramatically improving productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If scattering technique is used for color designs, then patterns can be applied, but resolution is coarse and repeat accuracy is limited

Engineering Contradiction:
Improvecolor design applicationVSAvoidresolution and repeat accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Digital printing technology replaces the imprecise scattering method with computer-controlled color deposition. This enables high-resolution printing with exact repeat accuracy by digitally reproducing design files, achieving photorealistic representations while maintaining design flexibility.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If protective films are applied to reduce abrasion, then abrasion resistance is improved, but adhesion is insufficient and upstanding edges occur

Engineering Contradiction:
Improveabrasion resistanceVSAvoidadhesion
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent merges the protective top layer with the color design layer into a single integrated printing layer. This combination ensures that the protective coating is applied uniformly over the printed surface, eliminating adhesion problems and upstanding edges while maintaining both protection and design integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The top layer is formulated as a composite material combining protective polymers with color pigments and binding agents. This composite structure provides both the required abrasion resistance and strong adhesion to the base layer, eliminating the need for separate protective films.

Inventive Principle:
Principle #40Composite materials

5Reliability

If maturing time is waited for linoleum production, then material properties are achieved, but production flexibility is severely limited

Engineering Contradiction:
Improvematerial propertiesVSAvoidproduction flexibility
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The production process is segmented into base layer production (requiring maturing) and separate printing operations. This allows the base layer to mature while design changes can be prepared in advance, and printing can be performed quickly once the base is ready, significantly improving production flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Design files and printing preparations are completed in advance while the base layer is maturing. This preliminary preparation of digital designs and printing parameters enables rapid production once the base layer is ready, minimizing the impact of maturing time on overall production flexibility.

Inventive Principle:
Principle #10Preliminary action
