Braiding Machine Reserve Zone Spindle Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing braiding machines struggle to produce uniform braided structures with significant variations in cross-section, resulting in inconsistent yarn density and angles between braided yarns due to the inability to adapt the number of spindles effectively.
Innovation Solution
A braiding machine with movable yarn feed spindles and reserve supports allows for easy addition or removal of spindles along a guide path, using a cooperative system between positioning elements and guide supports to maintain consistent yarn density and angles across varying cross-sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the number of yarn feed spindles is increased to produce larger cross-section braided structures, then the cross-sectional size is improved, but the yarn density decreases and angles between yarns increase
Solution Approach 1:
The patent implements a dynamic system where the number of active spindles can be varied during the braiding process. Spindles can be added to or removed from the guide path using positioning elements that cooperate with guide supports, allowing the machine to adapt the number of spindles to match the required cross-sectional size while maintaining consistent yarn density and angles throughout the braided structure.
2Volume of moving object
If the number of yarn feed spindles is decreased to produce smaller cross-section braided structures, then the cross-sectional size is reduced, but the yarn density increases and angles between yarns decrease
Solution Approach 1:
The patent enables dynamic adjustment of the number of active spindles by allowing spindles to be removed from or added to the guide path. This dynamic capability permits the system to reduce the number of spindles for smaller cross-sections while maintaining uniform yarn density and appropriate yarn angles, preventing both excessive density and angle variations.
3Quantity of substance
If spindles are removed from the guide path to interrupt braiding, then the cross-sectional size is reduced, but the yarn from removed spindles remains intertwined creating transition irregularities
Solution Approach 1:
The patent introduces reserve supports as intermediary elements that receive spindles removed from the guide path. These reserve supports act as mediators to manage the yarn from removed spindles during the transition phase, preventing abrupt interruptions and maintaining braiding uniformity while allowing the number of active spindles to be reduced for smaller cross-sections.
4Quantity of substance
If spindles are added to the guide path to increase cross-section, then the number of braided wires is increased, but complex operations are required to add spindles to the braiding
Solution Approach 1:
The patent segments the spindle management system into distinct functional components: guide supports along the guide path for active braiding, positioning elements for spindle attachment and detachment, and reserve supports for storing inactive spindles. This segmentation enables simple, modular operations to add or remove spindles without complex maneuvers, facilitating easy adjustment of the number of active spindles for different cross-sections.
