RFID Jewelry Ring Layout for Secure Inner-Side Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jewelry rings with RFID transponders are susceptible to unauthorized data access due to easy readability, posing a risk for secure data storage such as access to bank accounts or cryptocurrencies.
Innovation Solution
The RFID transponder is positioned inside the metal base with a blind-shaped bore recess, shielded from external access, using a non-metallic covering and near-field antenna with limited range, ensuring secure data transmission only from the inner surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the RFID transponder is placed on the outside of the jewelry ring for easy data access, then data readability is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The RFID transponder is extracted from the external surface and embedded into a recess in the metal base body, physically separating it from external access while maintaining its data storage and transmission functions. This extraction resolves the contradiction by hiding the transponder internally while preserving its operational capability through the antenna structure that extends through the metal base.
Solution Approach 2:
The RFID transponder is nested within the metal base body, with the antenna structure integrated into the metal base. This nesting arrangement allows the transponder to be concealed within the jewelry ring's structure while still enabling data transmission through the metal base, thus achieving both security through concealment and functionality through integrated antenna design.
2Object-affected harmful factors
If the RFID transponder is shielded within the metal base body for security, then protection against unauthorized reading is improved, but data transmission capability deteriorates
Solution Approach 1:
The antenna structure is designed with asymmetric configuration where one portion extends through the metal base body to the external surface while the transponder remains embedded internally. This asymmetric design allows the antenna to penetrate the shielding metal base and establish communication pathways, resolving the contradiction between internal shielding for security and external communication capability.
Solution Approach 2:
The antenna structure acts as an intermediary element that bridges the internal shielded transponder and the external reading environment. The antenna extends through the metal base body, creating a controlled interface that allows authenticated data transmission while maintaining the protective shielding, thus mediating between security requirements and transmission needs.
3Reliability
If the RFID transponder is embedded in a recess for secure attachment and shielding, then stability and protection are improved, but manufacturing complexity deteriorates
Solution Approach 1:
The recess for receiving the RFID transponder is pre-formed in the metal base body during the jewelry manufacturing process, before final assembly. This preliminary action integrates the transponder housing into the base structure itself, simplifying subsequent assembly and ensuring stable attachment without requiring complex post-manufacturing modifications or separate mounting components.
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 design effectively prevents unauthorized reading and manipulation of stored data, providing secure and reliable data access only when intended, while maintaining the ring's appearance and durability.
Implementation Method 1
The metal base body, with its closed outer surface, completely shields the RFID transponder from the outside, thereby completely blocking data transmission from the RFID transponder to a reader located outside the ring and vice versa.
Implementation Method 2
The RFID transponder is connected to an antenna structure or itself has an integrated antenna structure via which signals can be exchanged with a reading device.
