Tyre Changing Gripping Tool with Rim-Guided Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre changing machines require manual intervention and are complex to use, especially in positioning tools for correct bead extraction and insertion, and are not efficient for all tyre types without additional tools.
Innovation Solution
A device with a support, protruding elements, and a gripping tool that can be mounted on a tyre changing machine, allowing for automatic positioning and operation of the bead along the circumference, simplifying both fitting and removing processes without the need for additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional tyre changing machines with turrets are used, then bead extraction and insertion can be performed, but manual intervention is required and the operation becomes complex
Solution Approach 1:
The device enables self-positioning through the interaction between the protruding element and the groove on the rim. The groove guides the protruding element into the correct position automatically, eliminating the need for manual positioning by the operator. This self-service mechanism simplifies operation while maintaining the necessary device complexity for automated bead extraction and insertion.
2Extent of automation
If automated operating heads are used for bead extraction, then manual intervention is reduced, but positioning the head in correspondence with the bead becomes difficult
Solution Approach 1:
The groove on the rim acts as an intermediary element that facilitates the positioning of the protruding element. This intermediary structure guides the automated operating head into the correct position relative to the bead, combining automation with ease of positioning. The groove mediates between the automated mechanism and the specific location required for bead extraction.
3Reliability
If multiple tools are used for separation and extraction of the bead, then complete bead removal is achieved, but the device becomes constructively complex and harder to use
Solution Approach 1:
The device merges the functions of separation and extraction into a single integrated operating head. The gripping tool combines the separation function (lifting the bead from the rim) and the extraction function (pulling the bead along the rim) in one unified mechanism. This merging reduces device complexity while maintaining reliability through the coordinated action of the gripping elements and the protruding element working together.

AI summary
A device for fitting and removing tires includes a support having a connecting portion associable with the movable arm of a tire changing machine, a first protruding element associated with the support and suitable to be positioned in correspondence with a section of the edge of a wheel rim, a guide element having a substantially elongated shape and extending substantially orthogonal to the protruding element, a gripping tool associated with the support, suitable to be inserted between the tire and the rim and having a substantially curved end section, the gripping tool being movable between a retracted position, wherein the end section is arranged in proximity of the first protruding element, and an extracted position, wherein the gripping tool extends from the first protruding element towards the wheel. The first protruding element is arranged substantially at the side of the gripping tools, in correspondence with a side of the gripping tool substantially opposite to the guide element.
