Tire Vulcanization Bladder Assembly Without Vertical Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing tire vulcanization bladder assemblies are labor-intensive and time-consuming, requiring large-scale equipment and significant labor to invert the bladder vertically, which hinders productivity.
Innovation Solution
A method and device that attach ring parts to the bladder without vertically inverting it, using a base stage and support member to position and attach first and second ring parts to the clamp parts, facilitating assembly and enhancing productivity without large-scale equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bladder is vertically inverted to attach the second ring part, then the assembly process can be completed, but the device becomes large-scale and requires strong driving force
Solution Approach 1:
Instead of inverting the bladder to attach the second ring part, the patent attaches both ring parts while the bladder remains in its original upright position. The first ring part is attached to the lower clamp part, and the second ring part is attached to the upper clamp part without any inversion operation, thereby eliminating the need for large-scale inversion equipment.
Solution Approach 2:
The attachment process is segmented into two independent operations: first attaching the first ring part to the lower clamp part, then attaching the second ring part to the upper clamp part. This segmentation allows both attachments to be performed on a stable base stage without requiring the bladder to be inverted, simplifying the overall manufacturing process.
2Ease of manufacture
If the bladder is vertically inverted to attach the second ring part, then the assembly can be completed, but the operation time increases and productivity decreases
Solution Approach 1:
The patent eliminates the time-consuming inversion step by attaching both ring parts while the bladder remains upright. This reverses the conventional approach and directly addresses the productivity issue by removing the bottleneck operation.
Solution Approach 2:
The base stage is prepared in advance with positioning structures that accommodate both clamp parts simultaneously. This preliminary preparation enables both ring parts to be attached in sequence without interruption or inversion, streamlining the entire assembly process and improving productivity.
3Ease of operation
If the bladder is vertically inverted, then the second clamp part can be accessed, but labor and time requirements increase
Solution Approach 1:
Instead of inverting the bladder to access the second clamp part, the patent maintains the bladder in its upright position and accesses both clamp parts from their respective positions. The first clamp part is accessed from below and the second clamp part is accessed from above, eliminating the need for inversion while maintaining ease of operation.
Solution Approach 2:
The patent transitions from a single-dimensional vertical inversion approach to a multi-dimensional approach where the base stage accommodates both clamp parts in different spatial positions. This allows operators to work on both clamp parts simultaneously from different directions without requiring the bladder to be inverted.

AI summary
A tire vulcanization bladder assembly is manufactured by placing a first ring part on a base stage installed on leg parts in a periphery of a first end opening of a bladder; sandwiching a first clamp part of the bladder, the bladder being in an upright position with the first clamp part on a lower side and a second clamp part located in a periphery of a second end opening of the bladder on an upper side, by the first ring part, thereby attaching the first ring part to the bladder; inserting an inside ring member of a second ring part into the bladder from above on an inside ring member of the first ring part; moving the inside ring member of the second ring part upward relative to the bladder to a position of the second clamp part; and attaching the second ring part to the second clamp part.
