Dynamic Weaving Finishing for Non-Linear Edges and Internal Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for finishing woven products are limited to linear finishes on lateral edges, neglecting interior portions and requiring post-processing pattern cutting, which restricts design flexibility and efficiency.
Innovation Solution
A dynamic finishing device system that can independently finish one side of a woven product differently from the other side, allowing for non-linear finishes and positioning within the woven product to create apertures, pockets, and tunnels, using a combination of positioning mechanisms and programmable logic units to control finishing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional linear finishing methods are used on lateral edges, then the product maintains uniform width, but the design flexibility and ability to create complex shapes is limited
Solution Approach 1:
The finishing device is made dynamically positionable along the warp threads, allowing it to move from fixed lateral edge positions to variable positions including interior portions of the woven product. This dynamic positioning capability enables the device to create complex organic shapes while maintaining manufacturing precision through controlled movement.
Solution Approach 2:
The finishing device is divided into independent first and second finishing devices that can operate separately on different sides of the woven product. Each device can be independently positioned and controlled, allowing different finishing patterns on each side while maintaining overall product quality.
2Adaptability or versatility
If finishing is limited to lateral margins, then the process is simple, but interior portions of the woven product cannot be finished or modified
Solution Approach 1:
The finishing device is designed with multi-functionality to perform both traditional lateral edge finishing and interior portion finishing. The same device can be positioned at lateral margins or moved to interior portions, creating apertures, pockets, and tunnels in addition to standard edge finishing, eliminating the need for separate specialized equipment.
3Productivity
If non-linear organic shapes are created, then post-processing pattern cutting is eliminated, but the positioning and control system becomes more complex
Solution Approach 1:
The complex positioning and shaping actions are performed during the weaving process itself rather than as post-processing steps. The finishing device creates organic shapes and apertures while the fabric is being woven, eliminating the need for subsequent pattern cutting and post-processing operations.
4Adaptability or versatility
If independent side finishing is implemented, then each side can be finished differently, but the control system complexity increases
Solution Approach 1:
The finishing system is segmented into independent first and second finishing devices, each with its own positioning mechanism. This segmentation allows each side to be finished independently with different patterns and styles while using standardized control approaches for each unit.

AI summary
A dynamic finishing device that is able to finish one side of a product independently of a second side of the product while the product is being woven is provided. The sides may be finished in a non-linear fashion by the dynamic finishing device. Additionally, one or more finishing devices can be dynamically positioned in an interior portion of the woven product as it is being woven. Once positioned, the finishing devices may create apertures, pockets, and/or tunnels in the woven product and finish the edges of these creations. Finishing in the interior portions of the woven product occurs in the direction of the warp and in the direction of the weft.
