Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre changer machines are complex, costly, and difficult to use, with limited operator visibility and increased risk of error due to numerous movement apparatuses and complex structures, which hinder efficient tyre fitting and removal processes.
Innovation Solution
A tyre changer machine with a simplified design featuring a wheel-holder unit and operating heads with integrated tools that can be selectively positioned using a rotating mechanism, reducing the number of required movements and increasing reliability by allowing simultaneous operation of tools, thus minimizing operator intervention and machine size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools and movement apparatuses are used for tyre fitting and removal operations, then the machine can perform all necessary operations, but the device complexity increases and operator visibility is limited
Solution Approach 1:
The patent combines multiple tools (bead breaker, removal tool, fitting tool) and their supporting arms into a single integrated operating head. This operating head can perform all necessary tyre operations through rotational movement and tool extension/retraction, eliminating the need for multiple separate movement apparatuses while maintaining full operational capability
Solution Approach 2:
The operating head is designed as a universal device that can perform multiple functions: bead breaking, tyre removal, and tyre fitting. By integrating these functions into one device that can rotate and position different tools as needed, the patent reduces overall machine complexity while preserving versatility
2Adaptability or versatility
If numerous movement apparatuses and supporting arms are installed for each tool, then all tyre operations can be performed, but the machine dimensions increase and operator freedom of movement is hindered
Solution Approach 1:
Multiple separate supporting arms and movement apparatuses are merged into a single operating head structure. This consolidated design performs all tyre operations from one centralized location, significantly reducing the machine's overall footprint and freeing up workspace around the wheel
Solution Approach 2:
The operating head incorporates dynamic elements including rotational movement to position different tools, extendable/retractable tool mechanisms, and adjustable positioning capabilities. These dynamic features allow a compact device to access all necessary operational positions without requiring multiple fixed apparatuses
3Adaptability or versatility
If multiple separate tools are used for upper and lower bead operations, then complete tyre service can be provided, but the quantity of tools and apparatuses increases
Solution Approach 1:
The operating head is designed as a universal tool that can service both upper and lower beads through its rotational capability. By rotating the operating head to different positions, the same physical device can access and service both beads, eliminating the need for separate dedicated tools for each location
Solution Approach 2:
The operating head employs dynamic positioning through rotation and tool extension mechanisms. This allows a single set of tools to dynamically reposition itself to service different parts of the tyre (upper and lower beads) without requiring duplicate static tool sets
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the reliability and reduces the complexity of the tyre changer machine, providing a more efficient, cost-effective, and safer operation with improved operator visibility and reduced risk of error, allowing for easier tyre fitting and removal with fewer actions.
Implementation Method 1
a wheel-holder unit (6), configured to rotate a wheel (4) about a first axis of rotation, preferably vertical
Implementation Method 2
A first arm (15) (upper arm), having a first and a second end, the first upper end of which is coupled to the upper carriage, in such a way that it can translate along and rotate about a second axis of rotation, perpendicular to the first axis of rotation
