Solution Overview
Problem
The proliferation of various communication protocols among RFID readers creates a challenge for users who need to carry multiple access devices, each using different protocols for different applications, leading to inconvenience and inefficiency.
Innovation Solution
A universal access device that stores access data for multiple RFID readers and determines the appropriate protocol by interacting with each reader, allowing it to transmit access data using the correct protocol for each specific location and purpose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users carry multiple access devices for different RFID readers, then each device can access its specific system, but the user experiences inconvenience and inefficiency
Solution Approach 1:
The access device is designed to support multiple communication protocols (e.g., ISO 14443 Type A, Type B, FeliCa, Mifare) within a single device, enabling it to communicate with different types of RFID readers. The device includes protocol identification circuitry that automatically detects the reader type and switches to the appropriate protocol, making one device universally compatible with multiple access systems instead of requiring separate dedicated devices for each protocol
Solution Approach 2:
The access device dynamically adapts its communication protocol based on the detected reader type. The protocol selection is not fixed but changes in real-time based on the interaction with the RFID reader, allowing the device to optimize its communication method for each specific reader encountered
2Ease of operation
If a single access device supports multiple protocols, then user convenience improves, but device complexity increases
Solution Approach 1:
The access device automatically identifies the type of RFID reader through built-in protocol detection circuitry and autonomously selects the appropriate communication protocol without user intervention. The device self-configures its communication parameters based on the detected reader type, eliminating the need for users to manually select protocols or understand the different communication standards
Solution Approach 2:
The patent introduces a protocol identification and switching mechanism that acts as an intermediary layer between the user and the multiple communication protocols. This intermediary automatically detects the reader type and translates the user's access request into the appropriate protocol-specific communication, shielding the user from the underlying protocol complexity while maintaining support for multiple protocols
3Adaptability or versatility
If access data is stored for multiple RFID readers, then the device becomes more versatile, but the data management becomes more complex
Solution Approach 1:
The access device pre-stores access data for multiple different RFID readers in its memory, organized by protocol type. Before actual access is needed, the device has already prepared and stored the necessary credentials for various readers, allowing it to quickly retrieve and use the appropriate data once the reader type is identified, eliminating the need for real-time data processing or conversion
