Tyre Building Machine with Interchangeable Drums for Two Carcass Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire manufacturers require separate tire building machines for producing tire carcasses using the shoulder-type and flat-drum-type methods, limiting flexibility and efficiency in tire production.
Innovation Solution
A tire building machine with interchangeable first and second tire building drums, allowing production of tire carcasses using both the shoulder and flat drum methods, facilitated by a displacement shaft and adjustment mechanism for changing and adjusting drum diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate tire building machines are used for shoulder-type and flat-drum-type methods, then each machine can be optimized for its specific method, but the overall production flexibility and efficiency are limited due to requiring multiple machines
Solution Approach 1:
The patent applies universality by designing a single tire building machine that can perform both shoulder-type and flat-drum-type building methods through interchangeable drums. The machine is equipped with a receiving shaft that can accommodate different drum types (first drum for shoulder method, second drum for flat-drum method), allowing one machine to replace multiple specialized machines, thereby improving production flexibility while reducing the total number of machines required
2Productivity
If a single machine is designed to handle both building methods, then production flexibility improves, but the machine complexity and difficulty of operation increase due to drum interchangeability requirements
Solution Approach 1:
The patent applies dynamics by incorporating a displacement shaft that can be moved axially to facilitate drum interchangeability. The displacement shaft enables dynamic adjustment of the receiving shaft position, allowing smooth transition between different drum configurations. This dynamic mechanism simplifies the operation of changing drums compared to fixed designs, thereby improving ease of operation while maintaining high production efficiency through versatile building methods
3Adaptability or versatility
If drum diameter adjustment mechanisms are added to accommodate different building methods, then adaptability improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the drum system into interchangeable modular components (first drum, second drum, displacement shaft, receiving shaft). Each component can be manufactured independently with specific functions, and the modular design allows for standardized interfaces that simplify assembly and manufacturing processes. This segmented approach enables drum diameter adjustment and configuration flexibility without significantly increasing overall manufacturing complexity
