Tire Inner Wall Particle Flocking for Adhesion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sticky nature of self-sealing composition applied to tire inner walls after curing causes discomfort during transport and storage, as tire components adhere to each other, leading to structural damage and difficulty in applying the composition uniformly.
Innovation Solution
Applying particles to the inner tire wall using a flocking technique after curing, where the particles are made from shredded tires or manufacturing scrap, maintaining the tire's structural integrity and allowing for effective self-sealing without interference with tire performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self-sealing composition is applied to the tire inner wall after curing, then puncture resistance is improved, but adhesion between tire components occurs during transport and storage
Solution Approach 1:
A release film is introduced as an intermediary layer between the self-sealing composition and the tire components. This film prevents direct adhesion between sticky tire parts during transport and storage, while being removable without damaging the tire structure. The release film acts as a temporary mediator that eliminates the harmful adhesion effect while preserving the beneficial puncture resistance property.
Solution Approach 2:
The release film is applied selectively only to specific areas where adhesion problems occur, rather than covering the entire tire inner wall. This extracts the protective function from the general self-sealing layer, allowing the self-sealing composition to maintain its puncture resistance function while the release film handles the adhesion prevention function in targeted zones.
2Reliability
If self-sealing composition is applied to the tire inner wall after curing, then puncture resistance is improved, but uniform application becomes difficult
Solution Approach 1:
The release film is applied to the tire inner wall before the self-sealing composition is applied. This preliminary action creates a controlled substrate that facilitates more uniform application of the self-sealing material, as the release film provides a consistent surface that prevents premature adhesion and allows for better distribution of the composition during the application process.
