Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for automatically placing anti-noise strips inside tires are not entirely satisfactory, as they often result in manual placement or inadequate attachment, leading to issues like sliding and fold formation during the process.
Innovation Solution
A method and device that center the tire, apply adhesive, and drive the strip at a linear speed greater than the tire's rotation speed, creating a compressive effect to attach the strip end-to-end within the tire, ensuring perfect positioning and attachment without defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the strip is driven at a linear speed greater than the rotation speed of the tire, then the strip is compressed and positioned perfectly without sliding or folds, but the attachment process becomes more complex requiring precise speed control
Solution Approach 1:
The system dynamically adjusts the linear driving speed of the strip relative to the rotational speed of the tire. By controlling the strip to move faster than the tire rotates, a compressive effect is generated that ensures perfect positioning and eliminates sliding or folding defects during attachment.
Solution Approach 2:
The invention changes the speed parameter relationship between the strip and tire, specifically driving the strip at a linear speed greater than the tire's rotational speed. This parameter change creates the necessary compression effect for precise positioning while the adhesive device accommodates the speed differential to achieve end-to-end attachment.
2Reliability
If the strip is compressed to create space between ends for attachment, then end-to-end attachment is achieved, but the strip length becomes less than nominal length requiring precise control
Solution Approach 1:
The system performs preliminary compression of the strip during the attachment process itself. As the strip is driven into the tire at higher speed, it is compressed to create the necessary space between ends, which are then brought together and attached by the adhesive device in a continuous operation.
Solution Approach 2:
The invention merges the compression function and attachment function into a single integrated process. The adhesive device both compresses the strip to create end spacing and simultaneously attaches the ends together, eliminating the need for separate compression and attachment steps.
3Extent of automation
If automatic placement is implemented, then manual placement is eliminated, but the process requires complex coordination of tire rotation and strip driving speeds
Solution Approach 1:
The system employs feedback control to coordinate the tire rotation speed and strip linear driving speed. By monitoring the actual speeds and adjusting accordingly, the system maintains the required speed differential for compression while ensuring precise attachment, enabling full automation without excessive complexity.

Function Achieved in This Case
The solution enables automatic, precise placement and attachment of anti-noise strips inside tires, preventing sliding and fold formation, while ensuring effective noise reduction for various tire types and road surfaces.
Implementation Method 1
the strip, to which a pressure force is applied while it is being moved inside the tire, is moved inside the tire, said strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof
Implementation Method 2
after the release thereof, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end

AI summary
The invention presents a device and a method for placing and attaching a strip inside a tire. Specifically, the tire is positioned flat on a mounting between self-centering arms, and an adhesive device is placed inside the tire. While the tire is rotated, the strip is moved inside the tire, wherein a pressure force is applied to said strip. The strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.
