Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If RFID tags are used for product identification with minimal information storage, then the simplicity and portability of the system is improved, but the capability to manage and analyze aggregated user data over time and location is lost
Solution Approach 1:
The system divides functionality between RFID tags (minimal ID storage) and external management apparatus (data aggregation and analysis). The RFID tag only stores basic identification information, while the management apparatus separately collects, stores, and analyzes aggregated data from multiple tags over time and location.
Solution Approach 2:
A management apparatus acts as an intermediary between RFID tags and users. It collects wireless IDs from multiple tags, associates them with time and location information, and provides analysis capabilities without requiring the RFID tags themselves to store or process this additional information.
2Speed
If RFID readers provide real-time product information only, then the responsiveness of the system is improved, but the capability to retrieve historical information and perform user grouping is lost
Solution Approach 1:
The management apparatus preliminarily collects and stores wireless IDs along with time and location information in a database. This preliminary data accumulation enables both rapid real-time queries and historical analysis without requiring real-time data collection for every analysis operation.
Solution Approach 2:
The system adds time and location dimensions to the basic RFID identification function. By storing wireless IDs with temporal and spatial metadata, the system enables analysis across multiple dimensions while maintaining fast retrieval capabilities through organized data structures.
3Measurement precision
If the system focuses on individual product identification, then the precision of product tracking is improved, but the capability to analyze user behavior patterns and group users is lost
Solution Approach 1:
The system merges individual product identification data with user behavior data in a unified management apparatus. By collecting wireless IDs from multiple RFID tags and associating them with user information, time, and location, it enables both precise product tracking and user behavior pattern analysis simultaneously.
Solution Approach 2:
The management apparatus provides universal functionality that serves multiple purposes: individual product identification, user behavior analysis, user grouping, and historical data retrieval. This multi-functional system replaces the need for separate specialized systems.

Implementation Method 1
a wireless ID reader which reads out a wireless ID stored in a wireless ID tag in the vicinity through wireless communication
Data Source
AI summary
The RFID reader reads out an RFID stored in an RFID tag in the vicinity through wireless communication. The clock acquires an RFID readout time. The location sensor acquires an RFID readout location. The memory stores the RFID in association with the readout time and the readout location. The communication I/F acquires RFID-related information from a server asynchronously with readout of the RFID. The processor generates in the memory an RFID aggregate structure, which is a data structure of RFID aggregates constructed by classifying a plurality of RFIDs stored in the memory based on the readout time and the readout location and in which RFID-related information is stored in association with the constructed RFIDs.
