Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current weaving technologies lack the ability to dynamically combine different materials and apply varying tensions to achieve specific properties and patterns in textiles and apparel, limiting the creation of complex structures with desired functional and aesthetic characteristics.
Innovation Solution
A multi-functional weaving system that incorporates an intermittent splicer to dynamically terminate and combine materials, a dynamic tensioner to apply variable tension based on material properties, and finishing devices to independently finish sides and create apertures/pockets, enabling the production of woven products with varied properties and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional weaving technologies are used, then the weaving process is simple and easy to operate, but the ability to dynamically combine different materials and apply varying tensions is limited
Solution Approach 1:
The weaving system is divided into independent functional modules including an intermittent splicer module that separately handles material termination and combination, and a dynamic tensioner module that independently controls tension application. This segmentation allows each module to perform its specific function of combining different materials with varying tensions while maintaining overall system manageability.
Solution Approach 2:
The weaving system incorporates multi-functional components that can perform multiple operations. The intermittent splicer can terminate and combine various materials (yarn, thread, fiber) with different properties, while the dynamic tensioner can apply varying tension levels to different material segments. This multi-functionality enables the system to handle diverse material combinations without requiring separate dedicated devices for each operation.
2Adaptability or versatility
If traditional weaving technologies are used, then the device operation is straightforward, but the ability to create complex structures with desired functional and aesthetic characteristics is limited
Solution Approach 1:
The system employs dynamic control mechanisms where the intermittent splicer can selectively terminate and combine materials at different positions along the weaving path, and the dynamic tensioner can adjust tension levels in real-time based on material properties and desired structure. This dynamic capability enables the creation of complex structures with spatially varying functional and aesthetic characteristics while maintaining operational control through programmable sequences.
3Adaptability or versatility
If uniform tension is applied to all warp threads, then the weaving process is simple and consistent, but the ability to produce patterns and structures with varied properties is limited
Solution Approach 1:
The dynamic tensioner applies different tension levels to different segments or groups of warp threads based on their specific properties and the desired local characteristics of the woven structure. This localized tension control allows certain regions to have higher tension for durability while other regions have lower tension for comfort or pattern formation, creating varied patterns and structures with spatially differentiated properties.

AI summary
Different weaving materials, apparatuses, and methods are provided for producing woven textiles having different functional and aesthetic characteristics as compared to woven textiles produced using conventional methods. The different weaving materials comprise reactive materials or combined materials produced by an intermittent splicer. The different apparatuses include finishing devices for introducing organically-shaped lateral edges and interior apertures, and three-dimensional effectors for introducing three-dimensional aspects into a product as it is being woven. Weaving methods include simultaneously weaving fine denier panels and coarse denier panels.
