Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire changer machines are complex, costly, and prone to errors due to the need for multiple tools and manual operations, which increases the time and risk of error during tire removal and fitting.
Innovation Solution
An operating head with a connection element, supporting element, drive element, and fin that simplifies the tire fitting and removal process by stabilizing and guiding the tire bead without the need for a wall pressing tool, using a single piece design made from polymeric or metallic materials with a fin that contacts and guides the bead during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple tools and manual operations are used in conventional tire changer machines, then the tire removal and fitting operations can be performed, but the device complexity increases and operator errors increase
Solution Approach 1:
The patent combines multiple tools (operating head, bead breaker, removal lever, wall pressing tool) into a single integrated operating head assembly. The support element with protrusion and fin structure performs multiple functions: supporting the bead, preventing return to seat, and guiding insertion. This merging reduces device complexity while maintaining operational capability.
Solution Approach 2:
The operating head is designed as a universal tool that performs multiple functions: bead breaking, tire removal, and tire fitting operations. The support element with its protrusion and the fin structure enable the same device to handle different stages of tire service, eliminating the need for separate specialized tools.
2Productivity
If multiple tools and manual operations are used in conventional tire changer machines, then the tire removal and fitting operations can be performed, but the time required for operations increases
Solution Approach 1:
By integrating bead breaker, removal lever, and wall pressing tool functions into one operating head, the patent eliminates the time required to switch between multiple tools during tire service operations. The single integrated device performs all operations sequentially without interruption.
Solution Approach 2:
The support element with protrusion is designed to preliminarily support and position the bead before the actual removal or fitting operation. This preliminary positioning action prepares the bead for subsequent operations, reducing the total time required for complete tire service.
3Reliability
If multiple tools and manual operations are used in conventional tire changer machines, then the tire removal and fitting operations can be performed, but the risk of operator errors increases
Solution Approach 1:
The integration of multiple tools into a single operating head reduces the number of manual operations and tool transitions, thereby reducing opportunities for operator errors. The unified design ensures consistent performance across all tire service functions.
Solution Approach 2:
The fin structure and support element with protrusion are designed to automatically guide and position the bead during insertion and removal operations. This self-guiding mechanism reduces dependence on operator skill and minimizes the risk of manual positioning errors.
4Adaptability or versatility
If conventional tire changer machines use multiple tools, then various tire operations can be performed, but the cost of the machine increases
Solution Approach 1:
The patent merges bead breaker, removal lever, and wall pressing tool into a single operating head assembly, reducing the total number of components that need to be manufactured and assembled. This integration simplifies manufacturing processes while maintaining the versatility to perform multiple tire service functions.
Solution Approach 2:
The operating head is designed as a universal device that can perform bead breaking, tire removal, and tire fitting operations. This multi-functionality eliminates the need to manufacture and maintain separate specialized tools, reducing overall manufacturing complexity and cost.
