RF Transceiver in Metal Ring Using Dielectric Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to integrate radio frequency transceivers and RFID tags into rings or jewels made of conducting materials like gold, as the metal shielding attenuates or cancels electromagnetic waves, preventing effective radio frequency signal propagation and use in applications such as car remote controls and jewelry.
Innovation Solution
A ring or jewel assembly with a cavity filled with dielectric material, housing a radio frequency transceiver microelectronic device, which prevents contact with the metal and allows electromagnetic signal propagation by creating a space for wave transmission, using materials like precious stones or carbon fiber to reduce shielding effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ring or jewel is made of gold or other precious metal (conducting material), then it provides durability and prestige, but it shields electromagnetic waves and attenuates radio frequency signals
Solution Approach 1:
The ring is divided into two functional parts: a metal body for structural integrity and prestige, and a separate dielectric material section for electromagnetic wave transmission. This segmentation allows each part to fulfill its specific function without interfering with the other.
Solution Approach 2:
A dielectric material (such as ceramic, glass, or plastic) is introduced as an intermediary between the metal ring body and the radio frequency transceiver. This intermediary material allows electromagnetic waves to pass through while preventing direct contact between the conductive metal and the electronic components.
2Adaptability or versatility
If a radio frequency transceiver is integrated into a metal ring, then it enables remote control functionality, but the metal shielding attenuates or cancels electromagnetic waves
Solution Approach 1:
The ring structure is segmented into a metal body portion and a dielectric material portion, allowing the metal to provide structural support while the dielectric material enables electromagnetic wave propagation for remote control functionality.
Solution Approach 2:
Different portions of the ring have different material properties: the metal body provides durability and prestige, while the dielectric material portion provides electromagnetic wave transmission capability. This local differentiation of material properties allows both functions to coexist.
3Reliability
If dielectric material is used to prevent shielding effects, then radio frequency signals can propagate, but the device complexity increases
Solution Approach 1:
The dielectric material is integrated directly into the ring body structure, merging the structural and electromagnetic functions into a single unified component rather than adding separate external elements, thus minimizing overall device complexity.
Solution Approach 2:
The dielectric material serves multiple functions simultaneously: it acts as an electromagnetic wave transmission medium, provides structural support, and isolates the metal from electronic components. This multi-functionality reduces the need for additional separate components.

AI summary
A ring or jewel assembly has a radio frequency transceiver function. The assembly includes a metal body of the ring or jewel; a cavity in the body, filled, at least in part, by portions with dielectric material; and a radio frequency transceiver microelectronic device. The transceiver microelectronic device transmits and receives radio frequency signals SRF, with a spectrum belonging to a predetermined radio frequency range and is fixed to the body, at least partially inserted in the cavity and at least partially surrounded by the dielectric material. The dielectric material is interposed between the metal body and the transceiver microelectronic device, to prevent the transceiver microelectronic device from being in contact with the metal of the ring or jewel, and to form a space of dielectric material, adapted to allow propagation of electromagnetic signals SRF having a spectrum in the radio frequency range.
