RFID Bin Divider Conceals Tag for Automated Inventory Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage solutions require manual checking of inventory levels in storage bins, which is time-consuming and inefficient, especially when managing multiple bins with varying inventory levels.
Innovation Solution
An RFID-enabled storage bin with an adjustable bin divider that conceals an RFID tag from detection when inventory is sufficient and exposes it when levels reach a threshold, allowing for automated tracking and restocking notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual checking of inventory levels is used, then device complexity is reduced, but productivity decreases due to time-consuming manual checks
Solution Approach 1:
The RFID tag automatically transmits inventory level data to the system without requiring manual intervention. The system self-updates inventory status by receiving signals from RFID tags on items, eliminating the need for manual counting and tracking while maintaining simple operational procedures.
Solution Approach 2:
The patent replaces manual mechanical inventory checking with automated RFID electromagnetic field-based detection. RFID readers use electromagnetic fields to automatically detect and track items, substituting the mechanical process of manual inspection with a non-contact, automated electronic system that significantly improves productivity.
2Measurement precision
If RFID tags are always exposed for detection, then measurement precision of inventory levels is improved, but loss of time occurs due to continuous detection signals interfering with operations
Solution Approach 1:
The RFID tag's detectability is made dynamic rather than static. The tag can be concealed or exposed based on inventory status - when inventory is sufficient, the tag is concealed to avoid unnecessary detection signals; when inventory reaches threshold levels, the tag is automatically exposed for detection, optimizing both measurement precision and operational efficiency.
Solution Approach 2:
Instead of continuous exposure, the RFID tag is periodically exposed for detection only when necessary (at inventory threshold levels). This periodic action reduces unnecessary detection interference while maintaining accurate inventory monitoring, eliminating wasted time from constant detection signals.
3Productivity
If automated RFID tracking is implemented, then productivity is improved, but device complexity increases due to additional components
Solution Approach 1:
The bin divider serves multiple functions: it physically separates items within the storage bin and simultaneously acts as an RFID signal shield to conceal or expose tags. This multi-functionality reduces the need for separate dedicated shielding components, integrating the shielding function into the existing bin structure and minimizing additional complexity.
Solution Approach 2:
The RFID signal shielding capability is achieved by changing the material parameter of the bin divider to include RF-blocking properties. By selecting materials with specific electromagnetic shielding characteristics, the system achieves automated tracking functionality without adding complex mechanical or electronic shielding mechanisms.
