Solution Overview
Problem
Existing tire changing machines face difficulties in accurately positioning tools and controlling forces during the tire changing process, leading to potential damage to the wheel rim, tire, and machine components, as well as safety hazards due to improper tool placement and force management.
Innovation Solution
The implementation of a tire changing machine with a control system that includes sensors for force and position detection, coupled with actuators and a controller, which provides real-time feedback and haptic guidance to the operator, allowing for precise control of tool placement and force application to prevent damage and ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual or machine implemented tools are used to press the tire onto the wheel rim, then the tire changing process can be facilitated, but there is risk of damage to the wheel rim, tire, and machine components due to improper force control
Solution Approach 1:
The patent implements force sensors that continuously monitor the force applied during tire mounting and demounting operations. This feedback is transmitted to a controller that automatically adjusts actuator output to maintain force within safe operational limits, preventing damage to the wheel rim, tire, and machine components while facilitating the tire changing process.
Solution Approach 2:
The patent replaces manual mechanical force application with an automated control system that uses sensors, actuators, and a controller to precisely manage force application. This substitution eliminates the variability and potential for error inherent in manual operation, providing consistent and safe force control throughout the tire changing process.
2Extent of automation
If a clamping mechanism and drive mechanism are used to rotate the wheel rim, then the tire changing process is automated, but positioning accuracy of tools is compromised
Solution Approach 1:
The patent incorporates position sensors that continuously monitor the location of tools and the wheel rim during automated operations. This position feedback is transmitted to the controller, which adjusts actuator commands in real-time to maintain precise tool positioning accuracy throughout the automated tire changing process.
3Manufacturing precision
If force sensors and position sensors are added to the machine, then force control and positioning accuracy are improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional controller that integrates force monitoring, position monitoring, actuator control, and safety management into a single centralized system. This universal controller coordinates all sensors and actuators, managing the complex interactions between force and position control while maintaining system manageability and reducing operational complexity despite the addition of multiple sensors.

AI summary
Tire changing machines having force feedback and position control systems are described that may be used to control operation of one or more components of the machine during a tire change procedure. Information may be provided to a machine operator concerning detected operating conditions during the procedure. Excessive or abnormal forces or component positions can be detected and corrective action may be taken at any point in the tire change procedure. Successful component position profiles may be saved for future recall and execution by the machine.
