Tool-less Tire Mounting via Wheel Precessional Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fully automated tire mounting equipment is costly and space-intensive due to the need for sophisticated controls, actuators, and tools, lacking compactness and efficiency in the mounting process.
Innovation Solution
A tool-less tire mounting system that uses a master actuator and wheel support arm assembly to perform precessional and plunging motions, allowing the tire and wheel to interact directly without intermediate tools, with one acting as the installation tool, to achieve partial or full mounting without the need for traditional installation tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fully automated tire mounting equipment is used, then mounting productivity is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates the traditional installation tool (roller wheel or pressing device) from the mounting system. By having the wheel itself perform the urging action through precessional motion, the system removes the need for separate installation tools, reducing device complexity while maintaining automated mounting capability
Solution Approach 2:
The wheel serves dual functions: it is both the object being mounted and the installation tool that performs the urging action. The precessional motion of the wheel assembly causes the wheel to actively press the tire bead onto the rim, allowing the wheel to mount itself without external intervention, thereby simplifying the overall system
2Reliability
If traditional installation tools are used, then mounting effectiveness is improved, but space requirements increase
Solution Approach 1:
The patent merges the wheel mounting function with the installation tool function into a single integrated system. The wheel support arm assembly with precessional motion combines the positioning and urging functions that were previously separate, reducing the space required for equipment while maintaining mounting effectiveness
Solution Approach 2:
The wheel support arm assembly performs multiple functions: it positions the wheel, provides precessional motion for urging the tire bead, and eliminates the need for separate installation tools. This multi-functionality reduces the overall equipment footprint while maintaining reliable mounting performance
3Manufacturing precision
If sophisticated controls and actuators are used, then mounting precision is improved, but equipment cost increases
Solution Approach 1:
The precessional motion mechanism allows the wheel assembly to self-adjust and self-position during the mounting process. The mechanical precessional motion inherently provides the necessary precision for urging the tire bead onto the rim without requiring sophisticated electronic controls or sensors, reducing both cost and complexity while maintaining mounting precision

AI summary
A system for providing at least a partially mounted tire and wheel assembly is disclosed. The system includes the steps of using a prime mover to bring a tire and wheel together and using the primer mover to work on at least one of the tire or the wheel to mount the tire and the wheel together, wherein the work performed by the prime mover is the only positive work introduced into the tire/wheel system.
