Patterned Tufted Articles With Variable Pile and Seamless Graphics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current artificial turf production methods limit variations in pile length and stitch number, requiring multiple panels to be cut and customized for complex installations, leading to inefficiencies and quality issues due to manual installation of graphic elements.
Innovation Solution
A tufted article with patterned regions of varying color, pile height, and yarn density, produced by a system of tufting machines controlled by a controller, allowing seamless integration of patterns without seams, enabling continuous pattern formation across multiple panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional tufting specifications are used with fixed machine setups, then production process is simple, but product variations in pile length and stitch number are limited
Solution Approach 1:
The patent implements dynamic adjustment capabilities in the tufting machine, allowing pile length and stitch number to be varied continuously during operation. The machine setup includes adjustable components that enable real-time modification of tufting parameters without stopping production, transforming a static machine into a dynamic system capable of producing diverse patterns.
Solution Approach 2:
The invention changes key tufting parameters (pile length, stitch number, yarn type) during the manufacturing process. By incorporating variable speed drives, adjustable needle positions, and programmable control systems, the machine can modify these parameters on-the-fly to create different patterned regions within the same turf panel.
2Adaptability or versatility
If multiple discrete turf panels are produced and manually cut/assembled to create complex installations, then design flexibility is improved, but installation time and labor costs increase
Solution Approach 1:
The invention segments the tufting process into different zones within a single continuous production run. Each zone can be programmed to create specific patterns, colors, or textures, allowing complex designs to be produced in one continuous panel rather than assembling multiple discrete panels manually.
Solution Approach 2:
The patent enables continuous production of patterned turf panels by eliminating the need to stop the tufting machine for setup changes. The machine runs continuously, with parameters adjusted programmatically between zones, maintaining production flow while creating design variations throughout the panel.
3Adaptability or versatility
If manual cutting and gluing is used to install graphic elements, then customization is improved, but field integrity and quality consistency deteriorate
Solution Approach 1:
The invention performs all pattern creation during the tufting process itself, before the turf panel is completed. Graphic elements, logos, and design features are integrated into the panel during manufacturing through programmed needle selection and yarn delivery, eliminating post-production modifications.
Solution Approach 2:
The patent merges the graphic element creation with the main turf production process. Instead of treating graphics as separate components to be added later, the system integrates pattern formation into the primary tufting operation, creating a unified structure where graphics and turf are inseparable.

AI summary
A tufted article (e.g., an artificial turf panel) having a backing and a plurality of tufts extending through the backing. The plurality of tufts are distributed among a plurality of patterned regions. Each patterned region has at least one tuft of the plurality of tufts. The tufts of each patterned region differ from the tufts of at least one other patterned region of the tufted article in at least one of color, pile height, yarn type, or yarn density. At least one patterned region creates a longitudinal discontinuity in the color pattern of the tufted article. The tufted article does not have a seam. Complementary side edges of the tufted articles can be secured together to form at least a portion of the surface covering without the need for cutting or the use of inlay components.
