Tire Apex Integration for Embedded RFID Antenna
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of electromagnetic transmitting and receiving devices in tires is not optimally configured, requiring a rubber coating for the memory component, which increases technical complexity and costs.
Innovation Solution
The memory component is completely surrounded by the apex, eliminating the need for a rubber layer and simplifying the integration of the electromagnetic transmitting and receiving device within the tire, with a helical antenna component and a dual apex structure that minimizes dynamic forces and electromagnetic shielding effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electromagnetic transmitting and receiving device is introduced into the tire, then the tire gains communication and identification capabilities, but the technical effort and costs for coating the storage component with rubber increase
Solution Approach 1:
The storage component is integrated into the apex structure, merging the electromagnetic device housing with the existing tire component. This eliminates the need for separate rubber coating processes while maintaining protection and integration within the tire assembly.
Solution Approach 2:
The apex serves as an intermediary structure that houses and protects the storage component. By using the apex as the enclosing structure instead of applying rubber coating directly, the patent simplifies the manufacturing process while maintaining the necessary protection for the electronic components.
2Reliability
If the storage component is coated with rubber, then the electromagnetic device is protected within the tire, but the manufacturing complexity and costs increase
Solution Approach 1:
The protective function previously achieved through rubber coating is merged into the apex structure itself. The apex serves both as a structural component of the tire and as the protective housing for the storage component, eliminating redundant manufacturing steps.
Solution Approach 2:
The apex structure provides its own protective function for the storage component without requiring additional coating processes. The structural design of the apex inherently protects the electronic components while simplifying the overall manufacturing process.
3Adaptability or versatility
If the antenna component extends in the direction of rotation, then the transmitting and receiving capability is improved, but the antenna is exposed to greater dynamic forces
Solution Approach 1:
The antenna component is nested within or integrated with the apex structure, which provides mechanical support and protection. This nesting arrangement allows the antenna to extend in the rotation direction for optimal electromagnetic performance while the apex structure absorbs and distributes the dynamic forces.
Solution Approach 2:
The apex structure, potentially using composite materials with appropriate mechanical properties, provides both structural support and protection for the antenna. The composite construction allows the antenna to maintain its orientation for optimal communication while the apex material absorbs dynamic stresses from rotation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration simplifies the installation of the electromagnetic device, reduces costs, and enhances the tire's structural integrity and communication capabilities by minimizing dynamic forces and electromagnetic interference.
Implementation Method 1
RFID stands for Radio Frequency Identification and means identification using electromagnetic waves. Electromagnetic means electromagnetically acting. This means that the electromagnetic transmitting and receiving unit is designed to send and receive signals using electromagnetic waves.
Implementation Method 2
the at least one antenna component is designed as a helical antenna component. Due to the inventive circumstance in which the at least one antenna component is designed as a helical antenna component, a sufficiently broadband transmitting and receiving capability of the at least one antenna component can be ensured.
