Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tires with noise-absorbing agents hinder the reliable attachment and data transmission of sensors and reader devices, particularly when the reader device is integrated within the tire carcass.
Innovation Solution
A vehicle tire design that aligns a sensor in the tread with a module on the inner surface, ensuring a spot free from noise-absorbing agent for secure attachment, using markings and alignment methods to facilitate reliable data transmission through inductive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If noise-absorbing agent is provided on the inside of the tyre, then tyre noise is reduced, but the attachment of the reader device is hindered
Solution Approach 1:
The patent divides the inner surface of the tyre into two distinct zones: a first area covered with noise-absorbing agent for noise reduction, and a second area free from noise-absorbing agent for reliable attachment of the reader device. This spatial segmentation allows both noise reduction and secure attachment to be achieved simultaneously without interference.
2Reliability
If reader device is arranged in the tyre within its carcass, then data transmission connection is established, but attachment is hindered by noise-absorbing agent
Solution Approach 1:
The patent applies local quality by creating a specific zone (second area) on the inner surface of the tyre that is free from noise-absorbing agent. This localized modification allows the reader device to be attached in a specific location where attachment is not hindered, while the rest of the tyre maintains noise reduction properties. The local exemption area enables both data transmission reliability and manufacturing ease.
3Reliability
If sensor and reader device are aligned for data transmission, then data transmission is reliable, but attachment must be precise
Solution Approach 1:
The patent incorporates markings on the tyre that indicate the precise location of the second area free from noise-absorbing agent. These markings are applied in advance during tyre manufacturing, allowing the reader device to be attached at the correct location without requiring complex alignment procedures during installation. The preliminary placement of markings simplifies the alignment process while ensuring reliable data transmission between the sensor and reader device.
