Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling pneumatic tyres on vehicle wheels require multiple handling devices, which are costly and complicate maintenance.
Innovation Solution
A method using a handling robot with an articulated arm and gripper to coordinate the movement of a gripper and assembly tool, allowing the handling robot to perform all necessary tyre assembly tasks, including soaping and inflation, reducing the need for separate tools and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple handling devices are used for tyre assembly, then assembly precision and quality control are improved, but device complexity and maintenance costs increase
Solution Approach 1:
The patent combines multiple separate handling devices (tyre mounting device, rim handling device, soaping device) into a single integrated handling robot system. The robot executes coordinated movements to perform all assembly operations, reducing device complexity while maintaining assembly precision through centralized control.
Solution Approach 2:
The handling robot is designed as a multi-functional device that can perform various assembly tasks including tyre mounting, rim positioning, and soaping application. This universal device replaces multiple specialized devices, simplifying the overall system while maintaining the precision required for each specific operation.
2Reliability
If multiple separate devices are used for tyre assembly operations, then each operation can be optimized independently, but maintenance complexity and costs increase
Solution Approach 1:
By merging multiple independent devices into a single integrated robot system, the patent reduces the number of components that require maintenance. The centralized control system and unified mechanical structure simplify repair operations compared to coordinating multiple separate devices.
Solution Approach 2:
The universal handling robot performs multiple assembly operations with a single device, reducing maintenance complexity. Instead of maintaining multiple specialized devices, the system requires maintenance of one multi-functional unit, improving ease of repair while maintaining operational reliability.
3Manufacturing precision
If traditional multi-device assembly methods are used, then quality control is maintained, but production cycle time increases
Solution Approach 1:
The integrated handling robot performs assembly operations in continuous coordinated movements without the transfer times and positioning delays associated with multiple separate devices. The robot can smoothly transition between tyre mounting, rim positioning, and soaping operations, reducing total cycle time while maintaining quality control through precise control systems.
Solution Approach 2:
By combining multiple assembly operations into a single robot system, the patent eliminates the time required for transferring workpieces between separate devices and synchronizing their operations. The integrated system performs all operations in a streamlined sequence, reducing production cycle time while maintaining the quality control necessary for precise assembly.

AI summary
A handling robot includes an articulated arm movable in three directions, which carries a gripper at its free end for gripping and holding pneumatic tires. The pneumatic tire is held on its running surface by the gripper, taken from a provision position and moved to an optional wetting station for wetting the pneumatic tire with lubricant. The wetted pneumatic tire is then moved to an assembly station with a clamping device for releasably holding a wheel rim, which comprises a handling device with an assembly head equipped with assembly tools that can be guided along between the tire bead and the wheel rim flange. Here, the pneumatic tire is mounted on the wheel rim by a coordinated movement of the handling robot and the assembly head.
