Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing methods for product tracing, authentication, and compliance are used, then product identification can be achieved, but the implementation is inefficient and expensive
Solution Approach 1:
The patent uses NFC tags that store copied identification data from a central database, allowing efficient product tracing without expensive centralized verification systems. The tag contains a copy of the product's identification information that can be read locally by NFC readers.
Solution Approach 2:
The patent replaces traditional mechanical or optical identification systems (barcodes, RFID) with NFC technology, which uses electromagnetic near-field communication to achieve faster, more secure, and more efficient product identification and tracing.
2Reliability
If NFC tags with unique identifiers are implemented for real-time tracking, then product tracing and authentication efficiency is improved, but device complexity increases
Solution Approach 1:
The NFC tag is designed to serve multiple functions: storing product identification data, enabling authentication, supporting traceability, and facilitating recall operations. This multi-functionality reduces the need for separate systems for each purpose.
Solution Approach 2:
The NFC tag acts as an intermediary carrier that holds product identification information, simplifying the interaction between products and verification systems. The tag mediates between the product and the NFC reader, enabling easy data exchange without complex direct communication protocols.
3Loss of information
If existing identification methods are used, then basic product tracking is possible, but real-time data aggregation and analysis capability is insufficient
Solution Approach 1:
Product identification data is pre-loaded into NFC tags during manufacturing, so that when the product is scanned later, all necessary identification information is immediately available without requiring real-time database queries or data assembly.
Solution Approach 2:
The NFC system enables continuous tracking and data collection throughout the product lifecycle, from manufacturing to retail to consumer use. Data aggregation occurs continuously as products are scanned at various points in the supply chain, eliminating gaps in information.

AI summary
An apparatus for unique identification of an object using near-field communication (NFC), the apparatus includes at least a processor and a memory, wherein the memory contains instructions configuring the at least a processor to receive object manufacture data associated with a first object containing an NFC tag, generate a unique identifier as a function of the object manufacture data, assign the unique identifier to the NFC tag of the first object using an NFC reader at an initial time, obtain first identification data containing the unique identifier when the NFC reader communicates with the NFC tag of the first object at a time subsequent to the initial time, aggregate the first identification data with second identification data associated with a second object using a data aggregator, determine an object action datum as a function of the aggregated identification data, and transmit the object action datum to the NFC reader.
