Solution Overview
Problem
Existing methods for producing bead reinforcement composites in vehicle tires with spirally wound materials are complex and lack simplicity, making it difficult to achieve consistent and customizable winding patterns and densities.
Innovation Solution
A device with a rotatably mounted receiving device and a feed device that allows for controlled rotation and radial movement to spiral wind reinforcement materials onto a bead core, enabling precise control over the winding pattern and density, and facilitating easy adjustment for different tire requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple receiving device with a single support surface is used, then the device complexity is reduced, but the manufacturing precision and reliability of the bead reinforcement composite deteriorates due to inability to ensure proper centering and support of the carrier material
Solution Approach 1:
The support surface is segmented into multiple radially distributed support segments (at least three) that can be independently adjusted. Each segment can be pivoted about a tangential pivot axis to independently adapt to the contour of the carrier material, ensuring precise centering and support without requiring a complex monolithic structure.
Solution Approach 2:
The support segments are designed to be dynamically adjustable during the winding process. They can be pivoted between different positions to adapt to variations in carrier material contour, maintaining optimal support conditions while keeping the overall device structure relatively simple.
2Device complexity
If the support segments are fixed in position, then the device complexity is reduced, but the adaptability to different carrier material contours and tire specifications deteriorates
Solution Approach 1:
The support segments are designed to be dynamically adjustable during the winding process. They can be pivoted between different positions to adapt to variations in carrier material contour, maintaining optimal support conditions while keeping the overall device structure relatively simple.
Solution Approach 2:
The position and orientation parameters of the support segments can be changed during operation to adapt to different carrier material contours and tire specifications. This allows the same device to handle various product requirements without requiring complete redesign.
3Device complexity
If the feed device position is fixed radially, then the device complexity is reduced, but the ability to control winding density and pattern deteriorates
Solution Approach 1:
The feed device is designed with dynamic positioning capability in the radial direction. It can be moved to different radial positions during the winding process to control the winding density and pattern of the reinforcement material, enabling precise control over the bead reinforcement characteristics.

AI summary
The bond creating device has a drive device (18) for the controlled twisting of the receiving device, with variable feed device, the feed position of which to the support surface can be varied radially relative to the axis of rotation (2). The feed device supplies a belt- or thread-form carrier (12) for building up the bulge reinforcements (16, 17) from the open side. Another drive (19) can vary the feed device radially.
