Tire Assembly Securing Element for Parallel Structure Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire assemblies face challenges in maintaining the alignment of top and bottom structures during handling, leading to misalignment and structural non-uniformities, which degrade tire performance, and the use of sacrificial means for alignment is costly, difficult to dimension, and can cause production delays or damage.
Innovation Solution
A tire assembly with a securing element that has an elongation at rupture greater than a specific ratio of the assembly's conformation height to the sum of its structure thicknesses, ensuring parallel alignment of structures during handling and allowing separation without rupture, while withstanding shaping pressures and winding tensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sacrificial means are used to fix the top structure on the bottom structure during handling, then alignment is guaranteed, but production is slowed down and structural non-uniformities are created when means break
Solution Approach 1:
The patent removes the sacrificial means entirely from the system. Instead of using temporary fixing elements that need to be broken and removed, the invention uses the elastic securing element that remains permanently integrated in the assembly, performing both securing and structural functions without requiring removal or breaking.
Solution Approach 2:
The elastic securing element serves multiple functions simultaneously: it secures the top structure to the bottom structure during handling, maintains alignment, and remains as part of the final assembly. This multi-functional element replaces the single-function sacrificial means that only served for temporary alignment.
2Manufacturing precision
If sacrificial means are dimensioned to break during shaping, then alignment is maintained during handling, but misalignment and structural non-uniformities occur when they fail to break uniformly
Solution Approach 1:
The patent employs an elastic securing element that dynamically adapts to different stages of the process. During handling, its elastic properties maintain secure alignment; during shaping, it stretches to accommodate the separation of structures; and in the final assembly, it remains as a flexible structural component. This dynamic behavior eliminates the binary break/no-break dilemma of sacrificial means.
Solution Approach 2:
The invention changes the key parameter of the securing element from brittle (sacrificial means that must break) to elastic (elements that can stretch and return). This parameter change allows the element to withstand shaping pressures and winding tensions without breaking, while maintaining alignment throughout the process.
3Manufacturing precision
If sacrificial means are used to prevent relative slip, then alignment is maintained, but additional cost and complexity are introduced
Solution Approach 1:
The patent merges the function of alignment maintenance with the structural components themselves. The elastic securing element is integrated into the assembly as a permanent component rather than being a separate temporary fixture. This merging eliminates the need for additional sacrificial means and simplifies the overall assembly process.
