Solution Overview

Problem

Existing laminate floor elements lack high elasticity and optimal usage properties, which are essential for improved application and durability.

Innovation Solution

A floor element with a carrier board and a multi-layer wear coating comprising a damping layer, a decorative layer made of thermoplastic materials like polyethylene terephthalate (PET) or polypropylene (PP), and a wear layer, along with a backing for dimensional stability and moisture barrier, providing high elasticity and resistance to indentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a multi-layer wear coating with damping layer is applied to the carrier board, then elasticity and resistance to indentation are improved, but device complexity increases

Engineering Contradiction:
Improveresistance to indentationVSAvoidcoating structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent applies a multi-layer composite coating structure consisting of a damping layer (first layer) and a wear layer (second layer) on the carrier board. Each layer serves a specific function: the damping layer provides elasticity and indentation resistance, while the wear layer provides surface durability. This composite structure resolves the contradiction by combining materials with complementary properties to achieve both high strength and controlled complexity.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The coating is segmented into distinct functional layers: a damping layer made of thermoplastic material (PET or PP) for elasticity, and a wear layer for surface protection. This segmentation allows each layer to be optimized for its specific function, achieving superior indentation resistance through the damping layer while maintaining a relatively simple overall structure that can be manufactured efficiently.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If thermoplastic materials (PET/PP) are used instead of PVC, then environmental safety and elasticity are improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveenvironmental safetyVSAvoidcoating application precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent specifies precise parameter ranges for the thermoplastic damping layer, including thickness (0.3-3.0 mm) and density (30-800 kg/m³), to optimize both environmental safety and manufacturing precision. By defining these parameters clearly, the patent enables controlled manufacturing processes that can achieve the desired precision when working with thermoplastic materials, while avoiding the harmful effects of PVC and plasticizers.

Inventive Principle:
Principle #35Parameter changes

3Strength

If the damping layer thickness is increased to 0.3-3.0 mm, then elasticity is improved, but loss of substance increases

Engineering Contradiction:
ImproveelasticityVSAvoidmaterial consumption
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The patent provides a thickness range (0.3-3.0 mm) for the damping layer, allowing manufacturers to apply the minimum necessary thickness (0.3 mm) to achieve adequate elasticity for most applications, thereby reducing material consumption. The upper limit (3.0 mm) is provided for cases where higher elasticity is specifically required, enabling a balanced approach that minimizes material use while meeting performance requirements.

Inventive Principle:
Principle #16Partial or excessive action
