Modular Synthetic Grass Turf Assembly with Infill Retention Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synthetic grass turf assemblies are inflexible and permanently installed, making it difficult to convert between different sporting surfaces or events quickly and efficiently, and existing natural grass trays are costly and require extensive maintenance.
Innovation Solution
A modular synthetic grass turf assembly with a tile and sheet backing, featuring synthetic ribbons that extend upward and an infill layer of particulate material, along with a stiffer barrier of synthetic ribbons to retain the infill and facilitate easy assembly, disassembly, and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic grass turf assemblies are permanently installed, then the surface provides durability and stability, but the system loses flexibility and adaptability for different sporting events
Solution Approach 1:
The synthetic grass turf system is divided into modular interlocking tiles that can be independently assembled and disassembled. Each tile contains synthetic grass blades, infill material, and connection mechanisms, allowing the field to be reconfigured for different sports events by rearranging or removing specific tile sections while maintaining overall surface stability during use.
2Adaptability or versatility
If natural grass trays are used for field conversion, then the surface provides authentic grass appearance, but the system requires extensive maintenance and high operational costs
Solution Approach 1:
The system uses synthetic grass tiles that do not require growth, watering, or biological maintenance like natural grass. These tiles can be deployed temporarily for events and stored when not in use, eliminating the need for costly maintenance operations such as mowing, fertilizing, and pest control while providing a consistent appearance throughout the season.
3Duration of action of stationary object
If natural grass trays are transported for winter maintenance, then the grass can continue to grow, but the system increases transportation costs and logistical complexity
Solution Approach 1:
The synthetic grass tiles are designed to be non-biological and maintenance-free, eliminating the need for winter transportation to controlled environments. The tiles remain installed on the field throughout all seasons, providing continuous surface availability without requiring relocation for temperature-controlled growth conditions.
4Reliability
If infill layer is added to synthetic grass, then the turf provides better cushioning and stability, but the assembly becomes heavier and more difficult to transport
Solution Approach 1:
The infill material is distributed locally within each modular tile rather than as a continuous layer, allowing for optimized weight distribution. The interlocking tile design enables selective removal and transport of individual tiles or groups of tiles, reducing the practical handling weight compared to moving large sections of permanently installed infilled turf.

AI summary
A portable synthetic grass turf assembly—that is capable of being assembled, transported, disassembled, and stored—includes a plurality of synthetic grass module units that can be laid side by side atop a base surface to provide a continuous synthetic grass surface for various activities. Each module unit includes a synthetic grass turf with an infill layer of particulate materials disposed among the synthetic grass ribbons and atop a base sheet. A barrier of synthetic ribbons extends about the perimeter of the module unit to retain the particulate material within the module unit during its transportation and storage.
