Tyre Mounting Rail and Support Layout for Multi-Wheel Rims
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre mounting and demounting devices are designed for specific wheel types, requiring different systems for scooters, touring bikes, motocross bikes, and passenger cars, limiting versatility and efficiency.
Innovation Solution
A device with a main body, lockable running rails, and a bead breaker element, featuring detachable supports and a centring bar, allowing adaptation to different wheel types, and incorporating foldable legs and extendable bead breaker arms for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device is designed for a specific wheel type, then it can perform tyre mounting and demounting operations reliably, but it cannot be used with different wheel types such as scooters, touring bikes, motocross bikes, and passenger cars
Solution Approach 1:
The device is divided into a main body and detachable support elements that can be separated and reconfigured. The support elements can be removed and replaced with different types depending on the wheel type being worked on, while the main body remains constant.
Solution Approach 2:
The main body of the device is designed with universal features including rails with adjustable running rails and a centring bar mechanism that can accommodate different wheel types. By combining the universal main body with specific support elements, the device achieves multi-functionality across scooter, touring bike, motocross bike, and passenger car wheels.
2Adaptability or versatility
If multiple devices are used for different wheel types, then each wheel type can be serviced with a specialized device, but the quantity of devices and complexity increase
Solution Approach 1:
Multiple support elements designed for different wheel types are merged into a single device system. Instead of having separate devices for each wheel type, the support elements can be attached to the same main body, consolidating multiple functions into one device.
Solution Approach 2:
The device incorporates dynamic reconfigurability where support elements can be easily attached and detached from the main body. The running rails can be adjusted in position, and the centring bar can be adapted, allowing the device to dynamically change its configuration to match different wheel types without requiring complete device replacement.

AI summary
A device (1) for mounting and demounting a tyre and a method of preparing a device for mounting or demounting a tyre are proposed, wherein said device (1) has a main body (2) and a bead breaker element (5), said main body (2) having at least one rail (3), with at least one of said rails (3) having at least one lockable running rail (5) arranged thereon, and said bead breaker element comprising a bead breaker blade (10), a bead breaker arm (9), and a lever element (11), and wherein said device (1) comprises at least one support (8, 17), with at least one of the supports (8, 17) being detachably fastenable to at least one running rail (5), which makes it possible for tyres of different wheel types to be demounted from the wheel rim or mounted onto the wheel rim.
