Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are attached to individual electronic components for tracking, then component identification capability is improved, but management complexity of accommodation bodies worsens
Solution Approach 1:
The patent combines multiple RFID tags (attached to individual electronic components) with a master RFID tag (attached to the accommodation body) into a unified identification system. The master tag coordinates and manages the component tags, allowing simultaneous tracking of individual components and the accommodation body as a unit, thereby reducing management complexity while maintaining identification precision.
Solution Approach 2:
The RFID system is designed with multi-functionality to handle both individual component identification and accommodation body management. The master RFID tag serves multiple functions: identifying the accommodation body, tracking its location, monitoring inventory levels, and coordinating the identification of multiple component tags within it, thus addressing both identification precision and management complexity requirements.
2Loss of information
If detailed manufacturer information is stored locally on-site, then information accessibility is improved, but storage space requirements and system complexity worsen
Solution Approach 1:
The patent introduces a cloud-based server as an intermediary between the RFID tags and the information storage system. The RFID tags store minimal identification data and communicate with the cloud server, which holds the detailed manufacturer information. This intermediary approach enables fast local information retrieval through RFID reading while offloading substantial data storage to the cloud, reducing on-site storage requirements and system complexity.
3Device complexity
If manual inventory checking methods are used, then system simplicity is maintained, but time consumption and productivity worsen
Solution Approach 1:
The RFID-based inventory system enables self-service automated inventory management. The system automatically reads RFID tags on accommodation bodies and individual components, retrieves information from the cloud server, and updates inventory records without human intervention. This self-service capability dramatically improves inventory management efficiency while keeping the system relatively simple through the use of standard RFID technology and cloud services.

AI summary
A method includes manufacturer-side steps and user-side steps, the manufacturer-side steps include preparing an electronic component accommodation reel including an RFID tag storing a unique ID and storing electronic components, storing manufacturer-side information in association with the unique ID in a manufacturer-side information storage area of a cloud, shipping the electronic components in the form of the electronic component accommodation reel. The user-side steps include receiving and loading the electronic component accommodation reel shipped from the manufacturer-side facility, reading the unique ID stored in the RFID tag, and acquiring, based on the unique ID read, manufacturer-side information stored in the manufacturer-side information storage area of the cloud.
