Solution Overview

Problem

Traditional splicing devices and tensioning systems in weaving are passive and apply constant tension, limiting the ability to dynamically combine materials with varying properties and achieve specific aesthetic or functional properties in textiles and other woven products.

Innovation Solution

An intermittent weaving splicer and dynamic tensioner system that dynamically terminates and combines materials, applying variable tension based on material properties and desired product characteristics, allowing for precise placement and creation of materials with varied properties along the length of the combined material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional passive splicing devices are used to join yarn ends, then the basic splicing function is achieved, but the ability to dynamically combine materials with varying properties is limited

Engineering Contradiction:
Improveability to dynamically combine materialsVSAvoidsplicing device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The splicing device transitions from a passive, static system to an active, dynamic system that can automatically detect yarn ends, control material feeding, and adjust splicing parameters in real-time based on material properties and desired product characteristics

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensors and control logic that detect yarn end conditions and material properties, providing feedback to automatically adjust splicing operations and tensioning forces to optimize the combination of different materials

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If constant tension is applied to weaving material, then the tensioning function is simple, but the ability to achieve accurate placement and specific product properties is limited

Engineering Contradiction:
Improveaccurate placement of materialVSAvoidtensioning system complexity
Core Design Contradiction:
