Bead Seating Device Rigid Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire mounting apparatuses require manual operation for bead seating, leading to reduced machine safety and tire mounting speed due to the need for operators to hold bead seating devices during high air flow rates, resulting in inefficiencies and potential air loss.
Innovation Solution
A tire mounting apparatus with a bead seating device that is rigidly connected to the frame, allowing for stable operation during high air flow rates without manual holding, featuring a movable injection nozzle and actuator-controlled positioning to ensure precise bead seating and efficient air flow distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used for bead seating, then the operator can control the bead seating device, but machine safety is reduced and mounting speed decreases due to the need to hold the device during high air flow
Solution Approach 1:
The bead seating device is designed to be self-positioning and self-holding through rigid connection to the frame. The system automatically maintains the correct position during high air flow without requiring manual intervention, making the device serve itself rather than requiring operator holding.
Solution Approach 2:
The manual mechanical holding system is replaced with a rigid structural connection to the frame. The mechanical stability is achieved through the frame structure itself rather than through operator physical intervention, substituting human mechanical control with structural mechanical support.
2Ease of operation
If manual operation is used for bead seating, then the operator can adjust the device, but tire mounting speed is reduced due to the time required to hold the bead seater
Solution Approach 1:
The bead seating device is pre-positioned and pre-adjusted to the correct position before the bead seating operation begins. The rigid connection to the frame ensures it remains in this predetermined position throughout the operation, eliminating the need for continuous manual adjustment and holding during the process.
Solution Approach 2:
The device automatically maintains its position and adjustment settings through the rigid frame connection, serving itself without requiring ongoing manual intervention. This self-maintaining capability eliminates time loss associated with manual holding and readjustment.
3Stability of the object's composition
If a rigid coil is used for inflation, then the inflation system is stiffened, but the system is not suitable for carrying out bead seating operation
Solution Approach 1:
The bead seating device is designed as a multi-functional component that serves both bead seating and inflation functions. By integrating the bead seating nozzle and rigid positioning system into the frame, the system achieves universal applicability for both high-velocity bead seating operations and standard inflation operations without requiring separate dedicated systems.
Solution Approach 2:
The bead seating device and inflation system are merged into a single integrated structure connected to the frame. The rigid coil and bead seating nozzle share the same structural support system, combining previously separate functions into one unified apparatus that maintains stability for both operations.
4Device complexity
If a fixed nozzle is used, then the structure is simple, but air loss is considerable which reduces efficiency
Solution Approach 1:
The nozzle is designed with localized directional characteristics optimized for specific injection zones. Rather than a simple omnidirectional fixed nozzle, the structure incorporates directional flow control features at the local nozzle level to target air delivery precisely where needed, reducing wasteful dispersion while maintaining structural simplicity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus enables safe and efficient bead seating with high air flow rates, reducing the risk of operator injury and increasing tire mounting speed by maintaining the bead seating device's position during air injection, thus preventing cracks between the tire bead and rim flange.
Implementation Method 1
The bead seating device (4) is configured to generate an air flow to be injected between a flange of the rim and a bead of the tyre

AI summary
An apparatus (1) for mounting a tyre (P) on a respective rim (C) of a wheel (R) of a vehicle comprises: a frame (100); a chuck (3) which rotates about an axis of rotation (R1); a working tool (2) movable relative to the frame (100) towards the wheel (R); a bead seating device (4) configured to generate an air flow to be injected between a flange of the rim (C) and a bead of the tyre (P). The bead seating device (4) is movable relative to the chuck (3) along a transverse orientation (T), perpendicular to the axis of rotation (R1), between a rest position (P1), in which the bead seating device (4) is spaced from the rim (C), and a working position (P2), in which the bead seating device (4) is interposed between the flange of the rim (C) and the bead of the tyre (P). The bead seating device (4) includes a rigid element (401), an injection nozzle (403) and a duct (404). At the working position (P2), the bead seating device (4) is operatively constrained rigidly to the frame (100) and is configured to remain independently and fixedly stationary at the position (P2), even when subjected to a force generated by the air flow.
