Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of removing and replacing vehicle wheels is inefficient and poses physical hazards due to the need for manual handling and operation of tools, which can lead to time-consuming and potentially dangerous tire changes.
Innovation Solution
A system comprising computers, databases, and robotic apparatus that automatically determines wheel fastener patterns, removes and replaces wheels, and secures them using a robotic apparatus controlled by a computer network, allowing for automated wheel removal and replacement, including vehicle lifting and tire balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual wheel removal and replacement is performed, then the process can be completed with simple equipment, but the operation time increases and physical hazards occur
Solution Approach 1:
The patent replaces manual mechanical operations with an automated robotic system that uses computer vision and automated manipulation to remove and replace wheels. The robotic apparatus autonomously performs tasks such as detecting wheel positions, removing lug nuts, detaching wheels, and securing new wheels, eliminating the need for manual labor and associated physical hazards while significantly improving operational speed and consistency.
2Productivity
If automated robotic apparatus is used for wheel removal and replacement, then productivity increases and safety improves, but device complexity increases
Solution Approach 1:
The robotic apparatus is designed as a multi-functional system that can perform multiple operations including wheel detection, lug nut removal, wheel detachment, wheel replacement, and lug nut installation using a single integrated platform. This universal design consolidates what would otherwise require multiple separate devices into one system, managing complexity while maintaining high productivity and safety benefits.
Solution Approach 2:
The system incorporates autonomous capabilities where the robotic apparatus independently detects wheel positions, determines removal sequences, and executes operations without continuous human intervention. The computer vision system automatically identifies and tracks components, enabling the robot to self-navigate and self-adjust during the wheel replacement process, reducing operational complexity.
3Loss of time
If manual lug nut removal is performed, then tool requirements are simple, but the process becomes time-consuming
Solution Approach 1:
The robotic system replaces manual lug nut removal with automated robotic manipulators equipped with specialized end-effectors that can rapidly unscrew and remove lug nuts. The system uses computer vision to locate each lug nut and applies controlled mechanical force for removal, significantly reducing the time required compared to manual operation with wrenches or impact tools.

AI summary
Systems, methods and apparatus for automated vehicle wheel removal and replacement are provided. One system includes a computer system with applications for scheduling the replacement of tires for the vehicle. An electronically controlled lift device and robotic apparatus is configured for interaction with the computer system. The lift device mechanically adjusts arms for placement on lift points of vehicles. The robotic apparatus detects positioning of lug nut configuration for a wheel, removes lug nuts, and then removes the wheel from the wheel hub with gripping arms. The wheel and tire are then handed off to a separate tire changing machine. When a new tire is replaced the robotic apparatus then mounts the wheel to the original wheel hub, and then secures the lug nuts to the lug nut bolts.
