Multi-carrier Zonal Weaving System for Integrated Fabric Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional weaving methods lack the ability to create zonal features within woven materials, as they primarily maintain a consistent appearance and characteristics across the fabric width, with minimal variation, and existing multi-carrier systems only facilitate the interaction of a single weft yarn with warp yarns, precluding the integration of targeted performance zones.
Innovation Solution
A multi-carrier zonal weaving system where two carriers enter the shed of warp yarns from opposite sides and wrap weft yarns around an intermediate warp zone, creating a zonal feature without external yarns, allowing for dynamic placement and varying characteristics within the woven material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single-carrier weaving is used, then the manufacturing process is simple, but the fabric cannot have zonal features or varied characteristics across different areas
Solution Approach 1:
The fabric width is divided into multiple zones (first zone, second zone, third zone) with different characteristics. Multiple carriers are assigned to different zones, allowing each zone to have independent control over weft yarn insertion, tension, and pattern formation, enabling zonal features while maintaining manageable system complexity through modular zone management
Solution Approach 2:
The patent introduces a zonal dimension to traditional weaving by allowing different carriers to operate in different transverse zones simultaneously. This creates a multi-dimensional control structure where weaving parameters can vary across the fabric width, enabling zonal features without fundamentally changing the basic weaving mechanism
2Adaptability or versatility
If multiple carriers are used to transport a single weft yarn, then the system can cover wider fabric width, but the interaction between warp yarns is limited and zonal features cannot be created
Solution Approach 1:
Each carrier is assigned to a specific zone and controls weft yarn insertion locally within that zone. This allows different warp yarn groups in different zones to interact differently with weft yarns, creating zonal features such as varied tension, pattern density, or fabric thickness in specific areas while maintaining the overall fabric structure
Solution Approach 2:
The multiple carriers are designed with universal functionality to perform both transport and zonal feature creation. Each carrier can transport weft yarn across its zone while simultaneously controlling local weaving characteristics through adjustable tension, insertion timing, and interaction with specific warp yarn groups, eliminating the need for separate zonal control mechanisms
3Adaptability or versatility
If a common weft yarn is maintained across the entire fabric width, then the weaving process is simplified, but the fabric lacks targeted material properties or performance zones
Solution Approach 1:
Different zones of the fabric are assigned different material properties through localized control of weft yarn characteristics. The first zone may use one weft yarn type or tension for a specific function, while the second and third zones use different configurations for different functions, enabling targeted material properties without requiring complete redesign of the weaving process
Solution Approach 2:
The patent applies partial control to specific zones rather than controlling the entire fabric uniformly. By allowing different carriers to independently control weft yarn insertion in different zones, the system achieves zonal material property variation while maintaining efficient production in each zone, rather than requiring coordinated control of the entire fabric width

AI summary
A multi-carrier, zonal weaving system and method of manufacturing a zonal woven material is provided. The multi-carrier system includes a first weft yarn, a second weft yarn, and one or more intermediate warp yarns for wrapping by the first and second weft yarns. The zonal weaving method includes receiving a first weft yarn from a first origin via a first shed, wrapping it around one or more zonal warp yarns, and returned to the first weft origin after the first shed upper and lower yarns are exchanged. In further aspects, a second weft yarn is received from a second weft origin via a second shed, wrapped around the same intermediate, zonal warp yarns, and returned to the second weft origin after exchange of the second shed yarns. In one aspect, the first and second weft yarns are interlocked during wrapping of the common warp yarns.
