Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple NFC tags are used to support different functionalities (initial setup and listening), then the system can provide both one-touch initial setup and one-touch listening, but the device complexity increases and device size increases due to needing separate tags
Solution Approach 1:
The NFC tag is designed with a re-writable memory space that can store different types of information (AAR for initial setup, SSP for listening) at different times. A single NFC tag performs multiple functions by switching between different information types based on usage state, eliminating the need for separate dedicated tags for each function.
Solution Approach 2:
The patent combines the functionality of multiple separate NFC tags (initial setup tag and listening tag) into a single re-writable NFC tag. The tag merges different information storage capabilities (AAR and SSP) within one physical component, reducing device complexity while maintaining functional versatility.

3Volume of moving object
If a single NFC device is used for multiple functionalities, then device size is reduced, but the system must manage different information types (AAR and SSP) in the same storage space
Solution Approach 1:
The system performs preliminary actions by writing AAR information to the NFC tag during initial setup before it is needed. When listening mode is activated, the system then writes SSP information to the same tag in advance, preparing the appropriate information for the intended function before actual use occurs.
Solution Approach 2:
The NFC tag's memory content is dynamic rather than static. The system can rewrite the tag's information space between different usage modes - switching from AAR to SSP information as needed. This dynamic rewriting capability allows one tag to serve multiple functions without permanent dedications.
