Radial Braiding Machine Non-Circular Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radial braiding machines struggle to produce uniform braids for non-circular cross-sections, leading to thread distortions and non-uniformity, especially in flat braids, due to the limitations of circular braiding rings and clapper mechanisms.
Innovation Solution
A radial braiding machine with a braiding ring having a non-circular internal cross-section, such as oval or elliptical, and a thread deflection mechanism where the braiding ring's front side protrudes differently at various points, allowing for adjustable thread tension and placement, enabling precise control over thread intersections and core alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a circular braiding ring is used in a radial braiding machine, then the machine can produce round braided tubes with high uniformity and thread flow, but it cannot produce braids with non-circular cross-sections without thread distortion and irregularities
Solution Approach 1:
The patent applies asymmetry by changing the braiding ring's inner cross-section from circular to non-circular (oval, elliptical, rectangular, or polygonal) to match the desired braid cross-section. This asymmetric design allows the braiding ring to accommodate cores with varying cross-sections without causing thread distortion, thereby enabling production of flat braids and other non-circular shapes while maintaining thread uniformity.
Solution Approach 2:
The patent implements local quality by making different parts of the braiding ring have different properties - specifically, the inner cross-section is shaped differently at different locations (oval, elliptical, or polygonal) to match the local requirements of the core being braided. This localized adaptation allows each region of the braiding ring to work optimally with the corresponding section of the core, preventing thread distortion at edges and maintaining uniformity throughout the braid.
2Manufacturing precision
If a braiding ring with non-circular inner cross-section is used, then thread placement and tension can be optimized for various core shapes, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the geometric parameters of the braiding ring's inner cross-section (shape, size, orientation) to match the core being braided. The braiding ring can be configured with oval, elliptical, rectangular, or polygonal cross-sections, and can be rotated to different orientations. This parameter adaptation allows precise control over thread placement and tension without requiring complex additional mechanisms.
3Manufacturing precision
If the braiding ring front protrudes partially from the thread exit plane, then thread tension and placement position can be manipulated to improve braiding properties, but the device structure becomes more complex
Solution Approach 1:
The patent applies dimensionality change by extending the braiding ring front protrusions beyond the thread exit plane in the axial direction. These protrusions create additional spatial zones where threads can be guided and tensioned. By manipulating the height, position, and shape of these protrusions, the patent achieves precise control over thread placement and tension without requiring separate control mechanisms for each thread.
