Solution Overview

Problem

Existing hybrid turf mats lack an efficient construction that balances durability, comfort, and ease of installation while allowing for adequate growth of natural grass and permeability for water and air, with complex installation methods and inadequate space for root growth in known designs.

Innovation Solution

A mat with a base woven fabric using olefin synthetic yarns in a 3/8W, 5/12W, or 7/16W weave structure, featuring pile burls interlaced with weft yarns, providing a loose structure with specific density and pile height, allowing for natural grass growth and high permeability, and optionally incorporating natural fibers for biodegradability and additional stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the base is perforated after installation to provide permeability, then water and air permeability is improved, but installation complexity increases

Engineering Contradiction:
ImprovepermeabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base fabric is designed with inherent permeability features during manufacturing, specifically with a loose woven structure that provides natural spaces for water and air passage. This preliminary design eliminates the need for post-installation perforation operations, resolving the contradiction between achieving permeability and maintaining simple installation procedures

Inventive Principle:
Principle #10Preliminary action

2Strength

If the base fabric structure is made dense for durability, then strength is improved, but space for root growth and permeability deteriorates

Engineering Contradiction:
Improvebase strengthVSAvoidroot growth capability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The base fabric employs a loose woven structure with intentionally created spaces between yarns in specific regions. This local quality variation allows the base to maintain overall structural strength while providing localized pathways for root penetration and water/air permeability, resolving the contradiction between durability and root growth capability

Inventive Principle:
Principle #3Local quality

3Ease of operation

If natural grass is used for comfort, then comfort of use is improved, but durability under heavy use deteriorates

Engineering Contradiction:
Improvecomfort of useVSAvoiddurability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention creates a hybrid turf system that merges natural grass with synthetic elements. The base fabric provides structural durability and support, while natural grass grows through the base to provide comfort. This combination allows the system to simultaneously achieve the comfort of natural grass and the durability of synthetic materials under heavy use conditions

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A mat for a hybrid sport or decorative turf, having a form of a woven fabric, with a single-sided cover pile made of olefin synthetic yarns such as polyethylene and/or polypropylene and/or polyester, according to a 3/8W or 5/12W or 7/16W weave structure, comprising pile burls interlaced with weft, wherein the ends of the burls form synthetic grass blades. The mat has from 5000 to 20000 pile burls per m2, a warp density from 54 to 72 ends/10cm, a weft density from 30 to 80 ends/10cm and a pile height from 20 to 140 mm, wherein each pile burl (3) is interlaced at least two times over three weft fibres (5), and wherein the total surface mass of the mat is from 753 to 2105 g/m2.
