Tyre Bead Reinforcement Segmentation for Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tyre manufacturing processes using cylindrical forming supports often result in non-uniform reinforcing structures at the bead region, leading to homogeneity and flexibility issues, especially in low batch production and complex geometries.
Innovation Solution
A process and apparatus for sequentially depositing reinforcing elements of predetermined length and width on a cylindrical forming support, ensuring uniformity and flexibility by cutting a continuous band-like reinforcing element to size and arranging them without overlap, allowing for adjustable geometry and fitting changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tyre manufacturing processes use cylindrical forming supports with continuous band-like reinforcing elements, then production efficiency is maintained, but the reinforcing structure becomes non-uniform with overlaps and homogeneity issues
Solution Approach 1:
The continuous band-like reinforcing element is divided into discrete reinforcing elements of predetermined length through a cutting device. This segmentation eliminates overlaps and ensures uniform distribution of reinforcing elements around the cylindrical forming support, directly resolving the non-uniformity issue while maintaining continuous production flow
Solution Approach 2:
The system incorporates adjustable mechanisms that allow dynamic modification of the cutting frequency and positioning of reinforcing elements during production. This enables adaptation to different tyre geometries and batch sizes, maintaining production efficiency while achieving uniform reinforcing structures across various production scenarios
2Adaptability or versatility
If conventional processes use fixed geometry reinforcing structures, then manufacturing simplicity is maintained, but flexibility in fitting and design is reduced
Solution Approach 1:
The system allows modification of key parameters including the length, width, spacing, and angular position of reinforcing elements through adjustable cutting and positioning mechanisms. This enables customization for different tyre designs and fitting requirements without fundamentally changing the manufacturing process architecture
Solution Approach 2:
The apparatus is designed with universal features that allow it to produce different reinforcing element configurations for various tyre types and geometries. The combination of adjustable cutting device, positioning mechanisms, and forming support creates a multi-functional system that handles both low batch production and complex geometries effectively
