Problem
Existing authentication systems lack a compact and efficient solution for combining wired and wireless multi-factor authentication protocols in a single device, which can be both secure and user-friendly.
Innovation Solution
A device comprising a USB connector section and a cap section with embedded NFC antenna, where the USB connector adheres to USB standards and the NFC antenna adheres to NFC standards, enabling both wired and wireless communication protocols for authentication operations, with control circuitry performing authentication functions in parallel and using coils and capacitances to prevent signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple authentication protocols (USB and NFC) are integrated into a single device, then authentication versatility is improved, but device complexity increases
Solution Approach 1:
The patent combines USB wired authentication and NFC wireless authentication protocols into a single authentication device. The device includes both a USB connector section and an NFC antenna section, allowing it to perform multiple authentication methods simultaneously, thereby improving versatility while managing complexity through integrated design
Solution Approach 2:
The authentication device is designed with multi-functional capability to support both USB-based wired authentication and NFC-based wireless authentication. This universal design allows the single device to replace multiple separate authentication tools, enhancing adaptability across different authentication scenarios
2Volume of moving object
If USB connector and NFC antenna are integrated in the same device, then device compactness is improved, but signal interference between protocols increases
Solution Approach 1:
The authentication device is divided into distinct functional sections: a USB connector section and an NFC antenna section. Each section is designed to handle its specific protocol independently, with separate control circuitry and electrical connections, thereby reducing signal interference while maintaining compact integration
Solution Approach 2:
The patent introduces isolation circuitry and separate electrical connection paths as intermediaries between the USB and NFC components. This mediation prevents direct electrical interference between the two protocols while allowing both to coexist in the same device, effectively managing signal compatibility issues
3Ease of operation
If authentication device supports both wired and wireless protocols, then user convenience is improved, but manufacturing complexity increases
Solution Approach 1:
The NFC antenna section is designed to be engageable with the USB connector section, creating a nested or modular structure. This design allows the components to be manufactured separately and then assembled together through simple engagement mechanisms, reducing overall manufacturing complexity while maintaining multi-protocol functionality

AI summary
At least one example embodiment is directed to a device including a first section having a connector that enables communication according to a first protocol. The device may further include a second section engageable with the first section. The second section may include a cavity that houses the connector when the second section is engaged with the first section, and an antenna that enables wireless communication according to a second protocol when the second section is engaged with the first section.
