Current tyre-removal apparatuses are complex, unreliable, and difficult to maintain, with a lack of precision and efficiency in bead breaking and demounting operations, which can lead to damage to tyres, rims, and tools.
Innovation Solution
A tyre-removal apparatus with a base and rotating support, a movable support arm, and sensors to detect contact parameters, controlled by a unit that moves the tool along a predetermined or dynamically determined trajectory, ensuring precise movement both parallel and perpendicular to the wheel axis, using actuators like hydraulic or pneumatic systems for efficient bead breaking and demounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a disc-type bead breaker tool is used with manual positioning, then the device complexity is reduced, but the manufacturing precision and reliability of bead breaking operation deteriorate
Solution Approach 1:
The patent implements a sensor that detects contact between the bead breaker tool and the wheel, providing feedback to a control unit. This feedback mechanism enables automatic adjustment of the tool trajectory, ensuring precise bead breaking operations without requiring complex manual positioning systems.
Solution Approach 2:
The system performs self-positioning through automatic control. The sensor and control unit work together to autonomously adjust the support arm and tool position, eliminating the need for complex manual intervention and achieving precise bead breaking automatically.
2Reliability
If automated sensor control is implemented, then the manufacturing precision and reliability improve, but the device complexity increases
Solution Approach 1:
A sensor detects contact parameters between the tool and wheel, providing real-time feedback to the control unit. This feedback loop ensures reliable operation by automatically adjusting the tool trajectory based on actual contact conditions, preventing damage while maintaining operational consistency.
Solution Approach 2:
The patent replaces complex mechanical positioning mechanisms with an automated control system. The sensor and control unit substitute for manual mechanical adjustment, simplifying the overall system while improving reliability through electronic control and feedback.
3Ease of operation
If the support arm is moved manually, then the ease of operation is improved, but the manufacturing precision of tool trajectory deteriorates
Solution Approach 1:
The sensor provides real-time contact information to the control unit, which automatically adjusts the support arm trajectory. This feedback mechanism ensures precise tool positioning throughout the bead breaking process, eliminating the imprecision associated with manual positioning while maintaining operational simplicity.
Solution Approach 2:
The system performs self-positioning through automatic control based on sensor feedback. The support arm automatically adjusts its trajectory to maintain optimal contact between the tool and wheel, eliminating the need for precise manual positioning by the operator.
4Manufacturing precision
If precise automated control is used, then the manufacturing precision and reliability improve, but the ease of operation deteriorates
Solution Approach 1:
The system performs self-positioning and self-adjustment through automatic control based on sensor feedback. The support arm and tool automatically adjust their trajectories to maintain optimal contact, eliminating the need for operator intervention in precision positioning while maintaining operational simplicity through automated execution.

AI summary
A tire removal apparatus has a base with a support for rotating a wheel. A frame having an upright with a longitudinal axis substantially parallel to an axis of rotation of the wheel is joined to the base. A support arm associated with the upright is movable by an actuator in a direction substantially parallel to the axis of rotation of the wheel. A tool for operating on the wheel is mounted on the support arm. A sensor for detecting a parameter representing contact between the tool and the wheel is associated with the actuator, and is operationally connected to a control unit to control the actuator and/or another actuator associated with the support arm to move the tool along a trajectory determined by the control unit depending on the parameter representing contact between the tool and the wheel.
