Solution Overview

Problem

Conventional bead seaters are inefficient in creating an airtight seal between tire beads and rims due to their inability to deflect pressurized air and debris, and they do not accommodate wheel assemblies of varying shapes and sizes, especially when tires are stacked, making it difficult to aim the air blast into the tire opening.

Innovation Solution

A bead seating device with an inlet and multiple radially extending outlets, each with a leg and rotatable nozzle, designed to direct pressurized gas efficiently, featuring extendable legs and screens to deflect debris, allowing for effective seating of tire beads on rims of different dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single discharge barrel is used in conventional bead seaters, then the device structure is simple, but the ability to direct pressurized air efficiently into the tire cavity is reduced

Engineering Contradiction:
Improveefficiency of creating airtight sealVSAvoidnumber of outlets and nozzles
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The single discharge barrel is segmented into multiple outlets (first outlet, second outlet, third outlet, fourth outlet) arranged radially around the central axis. Each outlet connects to the common air source through the manifold, allowing pressurized air to be directed simultaneously from multiple positions into the tire cavity, improving sealing efficiency while maintaining structural simplicity through the common air source connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple outlets are merged into a single integrated device structure with a common air source connection. The manifold combines air flow from the single pressurized air source and distributes it to multiple outlets, achieving efficient multi-directional air delivery without requiring multiple separate air sources or complex independent control systems for each outlet.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If conventional blasters are used, then the device is simple, but the ability to deflect pressurized air and nearby debris is reduced

Engineering Contradiction:
Improvedeflection of pressurized air and debrisVSAvoidstructure with screens and deflectors
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Screens are introduced as intermediary elements positioned between the outlets and the tire cavity. These screens serve as mediators that deflect pressurized air in the desired direction while also deflecting debris away from the operator and surrounding area, reducing harmful effects without requiring complex active control systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The screens convert the potentially harmful scattering of pressurized air and debris into a beneficial controlled flow pattern. By strategically positioning the screens, the device redirects pressurized air toward the tire cavity while channeling debris away from sensitive areas, turning a harmful effect into a useful flow control mechanism.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Adaptability or versatility

If traditional blasters are used, then the device accommodates limited wheel assembly sizes, but the adaptability to wheel assemblies of different shapes and sizes is reduced

Engineering Contradiction:
Improveaccommodation of wheel assemblies of different shapes and sizesVSAvoidadjustable outlets and extendable legs
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The outlets are made dynamic and adjustable rather than fixed. Each outlet can be independently positioned and oriented to accommodate different wheel assembly configurations. The extendable legs allow the outlets to reach different distances, enabling the device to adapt to various tire sizes and rim geometries while maintaining a relatively simple base structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is designed with universal adaptability to handle multiple wheel assembly types. The combination of radially arranged outlets, adjustable positioning mechanisms, and extendable legs creates a multi-functional device that can effectively service different shapes and sizes of wheel assemblies with a single device configuration, rather than requiring multiple specialized tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If tires are stacked on top of each other, then storage space is optimized, but the opening between sidewalls is compressed making it difficult to aim air blast

Engineering Contradiction:
Improveability to aim air blast into compressed openingVSAvoidcompressed or narrowed opening between sidewalls
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The device utilizes radial arrangement of outlets around a central axis, providing air delivery from multiple angular dimensions rather than a single direction. This multi-dimensional approach allows at least one outlet to effectively target the compressed opening between stacked tire sidewalls, overcoming the geometric constraint of the narrowed opening through spatial versatility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention relates generally to tire servicing operations and, more specifically, to an improved tire bead seating device. The bead seating device may include an inlet configured to receive pressurized air. The inlet may couple to two or more outlets extending outwardly from a shell of the device. Further, a leg may extend downwardly from each outlet and include a nozzle for directing a pressurized gas into a cavity of a tire. In particular, pressurized air may be delivered via the nozzles to force the tire bead onto the rim flange. Advantageously, the bead seating device may emit a high volume of air through each nozzle to accommodate for wheel assemblies of different diameters.
