Tyre Mounting Tool Assembly with Integrated Carrier Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tyre mounting/demounting machines require complex designs and increased control efforts due to the need for multiple tool carrier arms and precise positioning of mounting and demounting tools, which complicates the process.
Innovation Solution
A mounting/demounting tool assembly with a carrier unit that integrates a bead breaker tool and a mounting support tool on the same carrier arm, utilizing partially congruent shapes for secure support and reduced control efforts, allowing for manual or automatic pivot movement between operative and inoperative positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tool carrier arms are used to hold mounting and demounting tools, then the machine can perform multiple functions, but the device complexity and control effort increase
Solution Approach 1:
The patent combines the mounting support tool and bead breaker tool onto a single tool carrier arm, eliminating the need for separate carrier arms for each function. This merging reduces the overall number of moving components and simplifies the control system while maintaining both mounting and demounting capabilities.
Solution Approach 2:
The tool carrier arm is designed to universally support multiple tool types (mounting support tool and bead breaker tool) through standardized support means. This allows a single carrier arm to perform multiple functions that previously required separate dedicated arms, reducing complexity while preserving versatility.
2Measurement precision
If multiple tool carrier arms are used for precise positioning of tools, then tool positioning accuracy is improved, but the control effort and device complexity increase
Solution Approach 1:
By merging multiple tool functions onto one carrier arm, the patent reduces the number of independent positioning systems required. The single carrier arm's positioning mechanism controls all tools simultaneously, reducing control effort while maintaining positioning accuracy through the standardized support means that ensure proper tool placement.
3Device complexity
If a mounting tool and demounting tool are supported by the same tool carrier arm, then the number of carrier arms is reduced, but the control precision for selecting and positioning tools decreases
Solution Approach 1:
The carrier arm is segmented into multiple independent support means (first support means for bead breaker, second support means for mounting tool), each capable of independently holding and positioning its specific tool. This segmentation allows precise positioning of each tool type while maintaining them on a single carrier arm structure.
Solution Approach 2:
Each support means on the carrier arm is designed with specific local characteristics optimized for its designated tool type. The first support means has features optimized for bead breaker positioning, while the second support means has features optimized for mounting tool positioning, ensuring each tool receives appropriate local support and positioning precision.
