Biometric RFID Device with Interchangeable Module Socket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing biometric RFID devices are not compatible with multiple RFID protocols, requiring unique designs for each protocol, leading to increased manufacturing costs and risks of over- or under-production due to the lack of standardization among RFID chips and modules.
Innovation Solution
A biometric identification device with a socket for receiving interchangeable RFID modules, allowing selection and installation of different RFID protocols after manufacturing, enabling a single device design to be used with various protocols, reducing production costs and improving flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unique device design is produced for each RFID protocol, then protocol compatibility is achieved, but manufacturing cost increases and production flexibility deteriorates
Solution Approach 1:
The device is segmented into two independent parts: a universal device body and protocol-specific RFID modules. The device body contains common components (antenna, biometric sensor, processing unit) that remain unchanged across protocols, while only the RFID module needs to be changed to support different protocols (125 kHz, 13.56 MHz, etc.). This segmentation allows mass production of the universal device body while maintaining protocol compatibility through module interchangeability.
Solution Approach 2:
The device body is designed with universal interfaces and architecture that can accommodate multiple RFID protocols through different modules. The socket interface, antenna connection, and control logic are standardized to work with any RFID module, making the device body universally compatible across protocols while keeping manufacturing costs low through economies of scale.
2Reliability
If a unique device design is produced for each RFID protocol, then protocol-specific optimization is achieved, but inventory management becomes complex and production risks increase
Solution Approach 1:
By segmenting the protocol-specific functionality into separate RFID modules, the system allows centralized production of standardized device bodies while RFID modules can be produced in bulk and stored as interchangeable components. This reduces inventory complexity compared to producing complete assembled devices for each protocol, as only modules need to be stocked rather than entire device assemblies.
3Adaptability or versatility
If RFID chips are not standardized, then protocol diversity is maintained, but device design complexity increases
Solution Approach 1:
The device body acts as an intermediary layer between the standardized device architecture and the diverse RFID chip protocols. It provides a unified interface and adaptation logic that translates between the common device operations and protocol-specific requirements, thereby supporting protocol diversity without increasing the complexity of the core device design.
