Inductive Antenna Coupling for Tire Sensor Mechanical Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic transmitting and receiving devices for tires are prone to mechanical stress, which can damage components such as solder joints, making it difficult to read information from the memory components.
Innovation Solution
The use of inductively connected primary and secondary antennas, along with a support component designed as a woven mesh or grid, and materials like rubber and brass casings, enhances mechanical stability and durability, allowing for reliable signal exchange through electromagnetic induction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solder joints are used to connect primary and secondary antennas, then electrical connection is achieved, but mechanical reliability deteriorates under tire operational stresses
Solution Approach 1:
The patent replaces the mechanical solder joint connection system with an inductive coupling system using primary and secondary antennas. This substitution eliminates direct mechanical connections between antenna components, allowing electrical signals to be transmitted through electromagnetic fields rather than physical contacts, thereby resolving the contradiction between electrical connection reliability and mechanical strength under stress
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary between the primary and secondary antennas. Instead of direct mechanical contact, electrical connection is achieved through inductive coupling where the primary antenna generates an electromagnetic field that induces current in the secondary antenna, serving as a mediator that transfers electrical signals without mechanical stress
2Manufacturing precision
If rigid structural components are used to support memory components, then manufacturing precision is improved, but adaptability to mechanical deformation deteriorates
Solution Approach 1:
The patent employs flexible antenna structures that can be integrated into the tire's rubber matrix. These antenna elements are designed to flex and deform with the tire while maintaining their electrical and inductive coupling functionality, allowing the system to adapt to mechanical deformation without compromising manufacturing precision or signal transmission
