RFID Tag Screw Connection for Tire Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio frequency electronic tags implanted in rubber tires face challenges such as complex production processes, risk of rubber damage from sharp base plates, difficulty in auto-implantation due to varying surface structures, antenna separation due to tire deformation, and non-replaceable antennas prone to damage.
Innovation Solution
The solution involves replacing the traditional base plate welding with a screw connection structure between the chip and antenna, eliminating the base plate entirely, and using adjustable screw or nut connections to ensure a secure and adaptable antenna-chip connection, preventing separation and allowing for easy antenna replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If base plate welding process is used to connect chip and antenna, then connection strength is improved, but production process complexity increases and manufacturing precision decreases
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a screw connection structure (mechanical fastening system). The antenna and chip are connected through screw threads that provide secure mechanical attachment without requiring welding operations, thereby simplifying the production process while maintaining connection strength.
Solution Approach 2:
The patent divides the RFID tag into separable components (antenna, chip, sleeve) that can be independently manufactured and assembled. The screw connection structure allows these segments to be connected through simple threading operations rather than requiring complex welding fixtures and processes.
2Strength
If base plate is used as structural support, then chip and antenna connection is improved, but harmful factors increase due to sharp edges cutting rubber
Solution Approach 1:
The patent removes the base plate component entirely from the RFID tag structure. Instead of using a base plate with sharp edges that could cut the rubber, the invention uses a sleeve-enclosed screw connection structure where all metal components are contained within the rubber matrix without exposed sharp edges, thereby eliminating the harmful cutting effect while maintaining structural integrity.
Solution Approach 2:
The patent introduces the sleeve as an intermediary component that encloses the antenna and chip assembly. This sleeve acts as a protective mediator between the metal components and the rubber, preventing direct contact between sharp metal edges and the rubber material, thus avoiding cutting damage while providing structural support.
3Reliability
If RFID is implanted during tire molding, then tire quality is improved, but difficulty of detecting and measuring increases due to bubble formation
Solution Approach 1:
The patent employs a sleeve with a smooth, curved surface design that facilitates bubble release during the molding process. The rounded geometry of the sleeve prevents bubble entrapment and makes any remaining bubbles more detectable, as they tend to rise to the curved surface rather than being trapped in sharp corners or flat interfaces.
4Reliability
If antenna is permanently welded to base plate, then connection reliability is improved, but ease of repair worsens due to non-replaceable antennas
Solution Approach 1:
The patent creates a dynamic connection system where the antenna can be selectively attached or detached from the chip assembly through screw connections. This allows the antenna to remain reliably connected during normal operation while enabling easy replacement when damaged or obsolete, transforming a static permanent connection into a controllable reversible connection.

AI summary
The present invention provides a radio frequency electronic tag for a rubber tire and installation method for frequency electronic tag. The radio frequency electronic tag comprises a radio frequency chip, antenna pins on the radio frequency chip, and antennae connected to the antenna pins. The tag is characterized in that the radio frequency chip is packaged in a sleeve having a smooth surface, inner ends of the antenna pins are connected to the radio frequency chip, external screw threads or internal screw threads are provided on outer ends of the antenna pins, and ends of the antennae are provided with screw connection structures matching the external screw threads or internal screw threads of the antenna pins. The tag replaces a chip antenna by welding process in tag production with a simple and reliable connection unit, and conveniently selects antennae having different lengths and shapes to be assembled with the electronic tag chip according to different requirements.
