Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for arranging transponders on vehicle tires face disadvantages such as air pockets, damage to tire components, and suboptimal signal transmission due to the lack of a durable and efficient integration of transponders with tire components.
Innovation Solution
A method involving a thin metal plate, specifically brass or brass alloy, is used to create flat antennas that are easily integrated into tire components, with an adhesion promoter ensuring a strong connection and precise manufacturing processes like punching, laser cutting, or water jet cutting to achieve high-strength connections and optimal antenna shapes for improved signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional transponder arrangement methods are used, then transponders can be installed on tires, but air pockets form between the transponder and tire components leading to poor bonding
Solution Approach 1:
The patent uses a thin metal plate (thickness < 1 mm) as the antenna structure, which is flexible enough to conform to the tire component surface without creating air pockets. This thin film approach allows the transponder to bond directly to the tire component, eliminating the bonding reliability issues caused by air pockets in conventional arrangements.
2Ease of manufacture
If conventional transponder integration methods are used, then transponders can be placed on tires, but tire components may be damaged during installation
Solution Approach 1:
The thin metal plate antenna (< 1 mm thickness) is sufficiently flexible to be installed without rigid support structures that could damage tire components. The flexibility allows the transponder to be integrated during tire production without compromising the structural integrity of the tire components.
3Strength
If thick metal plates are used for antennas, then structural strength is improved, but the transponder cannot be easily connected to tire components and may cause damage
Solution Approach 1:
The patent specifies a metal plate thickness of less than 1 mm, which provides sufficient structural strength for the antenna while maintaining the flexibility needed for easy connection to tire components. This thin film approach eliminates the need for complex connection mechanisms required by thicker, rigid antenna structures.
4Reliability
If conventional antenna structures are used, then transponders can function, but signal transmission quality is suboptimal due to poor positioning between tire components
Solution Approach 1:
The thin metal plate antenna can be easily positioned and bonded between tire components (such as between the apex and tire core) due to its flexibility and thin profile. This simple positioning approach achieves optimal signal transmission quality without requiring complex positioning mechanisms or multiple adjustment steps.
5Manufacturing precision
If complex manufacturing processes are used for flat antennas, then manufacturing precision is improved, but production speed decreases
Solution Approach 1:
The patent specifies a metal plate thickness parameter of less than 1 mm, which simplifies the manufacturing process while maintaining sufficient precision for the application. This parameter optimization allows for high-speed production methods such as punching, laser cutting, or water jet cutting to be used effectively, achieving both precision and productivity.
