Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire mounting and dismounting machines are complex to produce and require manual control during each work step, and existing solutions that use reaction forces for angular movement are not efficient for quick assembly and disassembly.
Innovation Solution
A device with a sliding extension component and articulated working tool that uses reaction forces from the tire and rim for angular movement, supported by a simple actuation system that moves the extension component along a sliding direction, allowing efficient and quick assembly and disassembly without active angular actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional actuators are used to drive tool angular movement during each work step, then precise control is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The tool uses the reaction force generated during the work process itself to drive its own angular movement. The reaction force from engaging the tire and rim automatically rotates the tool about the articulation axis, eliminating the need for external actuators to provide rotational control.
Solution Approach 2:
The patent replaces complex mechanical actuator systems with a simpler mechanism where the reaction force directly drives the angular movement. This substitution eliminates multiple actuators, control systems, and associated components while maintaining functional control.
2Ease of operation
If manual control operations are performed during every work step, then precise operation control is achieved, but productivity decreases
Solution Approach 1:
The system performs control operations automatically through the reaction force mechanism. Once the tool engages the workpiece, the reaction force automatically drives the angular movement and positioning, eliminating the need for continuous manual control inputs during each work step.
3Measurement precision
If complex actuation systems are used for tool angular movement, then control precision is improved, but manufacturing complexity increases
Solution Approach 1:
The patent extracts and eliminates the complex actuator systems from the design, retaining only the essential sliding mechanism and articulation. By removing unnecessary components, the design becomes simpler to manufacture while still achieving the required control through the reaction force mechanism.
4Device complexity
If reaction forces are used to drive tool angular movement, then device complexity is reduced, but assembly and disassembly speed may be affected
Solution Approach 1:
The system dynamically adapts to the workpiece geometry through the reaction force mechanism. The tool automatically adjusts its angular position in real-time as it engages different portions of the tire and rim, enabling efficient assembly and disassembly without rigid mechanical guidance systems.
