Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tyre mounting and demounting machines are complex, requiring high control efforts and precise positioning, which increases operational time and complexity, especially when handling both mounting and demounting tasks.
Innovation Solution
A method and machine design that simplifies control by using a movable mounting/demounting device with automatic adjustment based on an initial reference position, allowing manual adjustment in one direction while automatically adjusting in another, reducing the need for exhaustive control and minimizing machine complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tool carrier arms are provided with separate mounting and demounting tools, then the machine can perform both mounting and demounting operations, but the device complexity and control effort increase significantly
Solution Approach 1:
A single tool carrier arm is designed to carry both mounting tools and demounting tools, allowing the same physical structure to perform multiple functions. The control unit selectively activates appropriate tools based on the operation type, eliminating the need for separate dedicated tool carrier arms for mounting and demounting operations.
Solution Approach 2:
The patent combines mounting tools and demounting tools onto a single tool carrier arm structure. This merging of previously separate functions into one integrated system reduces the overall number of components and simplifies the mechanical design while maintaining full operational capability for both mounting and demounting tasks.
2Measurement precision
If precise positioning control is implemented for tool selection and placement, then operation accuracy improves, but control effort and operational time increase
Solution Approach 1:
The control unit automatically determines the appropriate tool position and activates the corresponding tool without requiring manual intervention for tool selection or positioning. The system self-manages the complex coordination of multiple tools on the carrier arm, reducing both control effort and operational time while maintaining precise positioning accuracy.
Solution Approach 2:
The control unit monitors the position and state of the tool carrier arm and automatically adjusts tool activation timing based on real-time position feedback. This closed-loop control ensures precise tool positioning and activation while minimizing the time required for tool changes and positioning operations.

AI summary
The invention relates to a method for mounting/demounting a tyre (T) on a rim (R). The method comprises the steps of: determining an initial reference position for the mounting/demounting device (U1, U2), said initial reference position being proximal to an edge (E) of the wheel rim (R); linking the position of the mounting/demounting device (U1, U2) with the initial reference position; adjusting the position of the mounting/demounting device (U1, U2) with respect to either the first or the second direction; continuously detecting the position of the mounting/demounting device (U1, U2) with respect to said either first or second direction; and continuously and automatically adjusting the position of the mounting/demounting device (U1, U2), with respect to the other one of said either first or second direction, at least in dependence of the initial reference position.
