Solution Overview

Problem

Existing mixed turfs face challenges in maintaining vegetative development and durability due to high drainage infill materials leading to dehydration and pollution issues, while synthetic turfs suffer from superheating and environmental discomfort, limiting their applicability and longevity.

Innovation Solution

A mixed turf design featuring a mat with profiled artificial fibers forming channels to store water, combined with a loose infill material that includes organic and mineral components, allowing for efficient water retention and root growth above the substrate, ensuring the turf's elasticity, shock absorption, and resistance to heavy use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If loose infill material with high drainage capability is used to keep artificial fibers vertical, then the artificial turf structure is maintained, but the natural plants suffer from water stress and dehydration

Engineering Contradiction:
Improvevertical orientation of artificial fibersVSAvoidwater availability for plants
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The infill material is segmented into multiple functional layers: a lower drainage layer for water evacuation and an upper water-retention layer with higher water capacity. This segmentation allows simultaneous fulfillment of drainage requirements for fiber stability and water retention requirements for plant survival.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the infill material have different water retention properties. The upper layer has higher water retention capacity to nourish plant roots, while the lower layer has higher drainage capability to maintain fiber orientation and prevent waterlogging.

Inventive Principle:
Principle #3Local quality

2Reliability

If frequent irrigation is applied to prevent plant dehydration, then plant survival is improved, but nutritive substances disperse and underground pollution occurs

Engineering Contradiction:
Improveplant survivalVSAvoidpollution from nutrient dispersion
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The infill material is pre-configured with water-retention capabilities in the upper layer, allowing the system to withstand irrigation intervals without external water input. This preliminary water storage capacity eliminates the need for frequent irrigation and prevents nutrient dispersion into the underground.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If synthetic turf is used to ensure steadiness and grip, then playing field stability is improved, but superheating and environmental discomfort occur

Engineering Contradiction:
Improveplaying field steadinessVSAvoidplaying field temperature
Core Design Contradiction:
Stability of the object's compositionVSTemperature

Solution Approach 1:

The system combines synthetic artificial fibers for structural stability and grip with natural plant elements for thermal regulation. The natural turf components provide cooling through evapotranspiration, counteracting the superheating effect of the synthetic materials while maintaining playing field steadiness.

Inventive Principle:
Principle #40Composite materials

4Object-affected harmful factors

If natural turf is used to provide aesthetic and environmental performance, then environmental benefits are improved, but the turf wears quickly and requires expensive maintenance

Engineering Contradiction:
Improveenvironmental performanceVSAvoidturf durability
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The system creates a composite turf structure where natural plant elements provide environmental benefits and aesthetic qualities, while the synthetic fiber matrix and infill material system provide structural support and durability. The artificial fibers absorb mechanical stress and foot traffic impacts, protecting the natural plants from wear while maintaining environmental performance.

Inventive Principle:
Principle #40Composite materials

AI summary

Turf (1) for sports, recreactional activities and/or for ornamental purposes comprising a mat of flexible material (10) equipped with a first face (11) and a second face (12) opposite to each other. To the mat (10) a plurality of fibres (20) are connected of an artificial material in such a way that it forms an artificial turf (50) that protrudes from the first face (11). The turf (1) comprises, furthermore, a measured amount of a loose infill material (50), for example of granular type, distributed on the face (11) of the mat (10). The turf (1) comprises, furthermore, natural vegetable material, i.e. plants, belonging to one, or more plant species (30) put in the loose infill material (50) by means of sowing, traplantation of portions of plants, or a combination of the two solutions. The fibres of artificial material (20) have a profiled shape comprising a main blade (21) and at least one side wing (22). More precisely, the side wing (22) has a curved profile suitable for forming a channel (25) arranged substantially parallel to the main blade (21) in order to form a channel that is substantially parallel to said main blade, so that the profile of the channel partially or completely encircles the spaces that are occupied by water, roots and loose infill material, creating a water reserve for roots.
