Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users want to add RFID function to their existing mobile terminal, then RFID functionality is improved, but purchase cost increases significantly
Solution Approach 1:
The invention separates the RFID module from the mobile terminal, placing it in a removable memory card instead. This allows users to add RFID functionality by simply inserting a card rather than purchasing a new device, significantly reducing cost while maintaining adaptability.
Solution Approach 2:
The memory card is designed to work with multiple different mobile terminal models and support various RFID protocols (ISO 14443A, ISO 14443B, FeliCa), making it a universal solution that can be used across different devices and applications without requiring device-specific customization.
2Adaptability or versatility
If diverse RFID protocols are supported in different mobile terminals, then protocol versatility is improved, but compatibility between devices deteriorates
Solution Approach 1:
The memory card integrates support for multiple RFID protocols (ISO 14443A, ISO 14443B, FeliCa) within a single device. The card automatically detects and adapts to the appropriate protocol based on the reader type, ensuring reliable compatibility across different mobile terminals without requiring each device to be individually configured for multiple protocols.
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
Enables users to add RFID functionality to their devices at a lower cost and improves compatibility by allowing the memory card to adapt to different RFID protocols, expanding RFID applications to various handheld devices with a memory card interface.
Implementation Method 1
Radio Frequency Identification (RFID), commonly referred to as Electronic Tag, is a technique that utilizes spatial coupling (alternating magnetic field or electromagnetic field) of radio frequency signals to implement contactless information transmission
