Patterned Tufted Turf Fabric Formation via Selective Yarn Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for forming patterned tufted fabrics, such as synthetic sports turf, are labor-intensive, lead to material waste, and result in inaccuracies due to the need for post-installation template cutting and gluing of designs, while also requiring excessive fill material that can cause player discomfort and injury.
Innovation Solution
A system and method using a tufting machine with needles arranged in various configurations and a gauging element assembly to form patterned tufted fabrics by selectively picking up and cutting yarns within a backing material, allowing for integrated pattern formation without post-installation modifications, reducing the need for fill material and improving cushioning and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If post-installation template cutting and gluing methods are used to form patterns, then design flexibility is improved, but labor intensity and time consumption increase significantly
Solution Approach 1:
The pattern design is integrated into the tufting process itself, where selective yarn pickup and placement during manufacturing creates the desired pattern. This preliminary action eliminates the need for post-installation cutting and gluing operations, significantly reducing labor intensity and time consumption while maintaining design flexibility.
Solution Approach 2:
The invention merges the pattern formation function with the turf manufacturing process by using a tufting machine that can selectively pickup and place yarns according to a predetermined pattern. This combines what were previously separate operations (manufacturing and pattern creation) into a single integrated process.
2Strength
If excessive fill material is used to support synthetic turf filaments, then structural support is improved, but player comfort and safety deteriorate due to eye irritation and injury risk
Solution Approach 1:
The invention applies local quality by creating zones of varying yarn density and loop height within the turf structure. Areas requiring additional support have tighter, shorter loops while other areas maintain natural cushioning properties. This localized variation provides structural support where needed without requiring excessive fill material throughout the entire turf, thereby reducing player discomfort and safety risks.
Solution Approach 2:
The invention changes physical parameters of the turf structure, specifically varying loop height, yarn density, and pile length in different zones. These parameter changes allow the turf to provide adequate structural support with reduced fill material, improving player comfort and safety by minimizing the amount of loose particulate matter that can cause eye irritation and injury.
3Ease of manufacture
If conventional tufting methods are used, then manufacturing simplicity is maintained, but pattern precision and design clarity are compromised
Solution Approach 1:
The tufting machine is equipped with a computer-controlled yarn selection system that automatically picks up and places the correct yarns in the correct positions according to the digital pattern design. This self-service capability eliminates the need for manual pattern creation while maintaining manufacturing simplicity, achieving both high pattern precision and ease of manufacture.
Solution Approach 2:
The invention replaces manual mechanical pattern creation with a computer-controlled system that uses sensors, actuators, and programmable logic to selectively engage and disengage yarn feeders. This substitution of mechanical control with automated systems maintains the simplicity of the tufting process while dramatically improving pattern precision and design clarity.

AI summary
A system and method for forming synthetic/artificial grass or turf products in which a series of tufts of artificial/synthetic grass filaments or yarns are formed in a backing material with various graphic pattern effects being formed therewith. The system generally will include at least one needle bar having at least one row of needles mounted along a tufting zone and reciprocated through the backing to a desired penetration depth, and will present a desired set or group of yarns to a series of pattern pixels or stitch areas. A series of level cut loop loopers or hooks will be aligned with and will engage the needles in order to form tufts of yarns in the backing material. Clips of the level cut loop loopers will be selectively controlled to control the retention of selected ones of the yarns presented at each pattern pixel. The remaining, non-selected yarns generally are not retained at the pattern pixels, and can be formed as lower pile tufts or removed from the backing material.
