3D Tire Fabric Assembly With Slip Securing Element for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assemblies for tire structures face alignment issues during handling, leading to misalignment and compromised tread flattening, with sacrificial means being difficult to dimension accurately and potentially causing manufacturing delays or misalignment.
Innovation Solution
An assembly comprising a first and second structure held together by a filamentary securing element that allows relative slipping at its ends, ensuring parallel alignment and superposition without breaking, using textile, metal, or composite filaments that withstand high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sacrificial means are used to fix the top structure onto the bottom structure during handling, then alignment is maintained, but manufacturing is slowed down and the means may break at the wrong time
Solution Approach 1:
The patent removes the sacrificial means entirely from the assembly. Instead of using temporary fixing elements that need to be dimensioned and later removed, the invention relies on the friction forces between the supporting structure and the top/bottom structures to maintain alignment during handling and manufacturing.
Solution Approach 2:
The assembly utilizes its own friction forces to maintain alignment without requiring external sacrificial means. The supporting structure's friction interaction with the top and bottom structures automatically provides the alignment function that would otherwise require separate fixing elements.
2Manufacturing precision
If sacrificial means are used to prevent slippage during handling, then alignment is maintained, but the means may not break at the correct time causing manufacturing delays
Solution Approach 1:
The patent eliminates the sacrificial means completely, replacing it with a friction-based system that maintains alignment throughout the entire manufacturing process without requiring timed failure. The friction forces continuously provide alignment without the reliability issues of timing-critical breaking points.
Solution Approach 2:
The invention changes the parameter of alignment maintenance from a discrete event (sacrificial means breaking at a specific time) to a continuous state (friction forces constantly maintaining alignment). This transforms the reliability requirement from timing-critical to continuously stable.
3Manufacturing precision
If the supporting structure is made taut to prevent relative movement between structures, then alignment is maintained, but the handling becomes more difficult
Solution Approach 1:
The patent creates a dynamic balance where the supporting structure provides enough friction force to maintain alignment during normal handling, but allows movement when deliberate force is applied. The system adapts its rigidity based on the applied forces, being flexible enough for handling but stable enough for precision.
Solution Approach 2:
The invention changes the mechanical property of the supporting structure from a fixed taut state to a friction-based state that provides variable resistance. The friction forces provide sufficient constraint for alignment while maintaining flexibility for handling operations.
