Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk of misalignment between the center axis of the pair of split rim members and the rotation axis of the tire mounted on them, leading to precision issues in tire measurement, processing, and testing.
Innovation Solution
A tire mounting method that includes a clamping, approaching, and rotating step to align the rotation axis of the tire with the center axis of the split rim members using a tire holding device with telescopic parts and air injection, ensuring precise alignment through controlled expansion and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tire is mounted on a pair of split rim members, then the tire can be held for measurement, processing, and testing, but misalignment between the center axis of the split rim members and the rotation axis of the tire may occur due to the weight of the tire
Solution Approach 1:
The patent applies preliminary action by performing the rotating step during the mounting process to proactively align the tire's rotation axis with the center axis of the split rim members before measurement, processing, or testing begins. This prevents misalignment from occurring in the first place, rather than correcting it afterward.
Solution Approach 2:
The patent employs dynamics by making the split rim members rotatable during the mounting process. This dynamic adjustment allows the tire to be rotated into proper alignment with the center axis, compensating for the gravitational effect of tire weight that would otherwise cause static misalignment.
2Manufacturing precision
If the tire is held between the split rim members without alignment control, then the mounting process is simple, but precision in tire measurement, processing, and testing is compromised
Solution Approach 1:
The rotating step is performed as a preliminary action during mounting to establish proper alignment before the tire undergoes measurement, processing, or testing. This ensures precision is achieved proactively without requiring complex alignment mechanisms during subsequent operations.
Solution Approach 2:
The tire itself serves to generate the alignment through its own weight and geometry during the rotating step. As the split rim members rotate, the tire naturally settles into the correct position with its rotation axis aligned with the center axis, eliminating the need for external alignment devices or complex control systems.
