Solution Overview

Problem

Managing perishable product inventories is challenging due to the difficulty in tracking expiration dates and preventing the inclusion of expired products in orders, leading to inefficiencies and resource wastage.

Innovation Solution

A product inventory management system using RFID tags to track expiration information for perishable products, with an electronic communications device that scans the tags to identify expired products and performs mitigation actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If barcode scanning is used to track products, then product location can be identified, but manual scanning may be overlooked or performed inconsistently leading to tracking errors

Engineering Contradiction:
Improveproduct tracking accuracyVSAvoidorder fulfillment reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces manual barcode scanning with RFID (radio frequency identification) technology. RFID tags attached to products and vessels enable automatic identification and tracking without manual intervention, eliminating human error in scanning while maintaining product location tracking capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If RFID tags are used to track product location, then product location can be automatically identified, but expiration information management remains challenging

Engineering Contradiction:
Improveproduct location identification efficiencyVSAvoidexpiration information management
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent combines location tracking and expiration date management into a single integrated RFID system. The RFID tags store both location data and expiration information, allowing simultaneous automatic identification of product location and verification of expiration status during order fulfillment processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements feedback mechanisms where RFID readers automatically verify expiration dates against order requirements. When expired products are detected, the system provides feedback alerts to prevent their inclusion in orders, ensuring continuous monitoring and correction of expiration management.

Inventive Principle:
Principle #23Feedback

3Device complexity

If manual inventory management is used, then system complexity is low, but expired products may be inadvertently included in orders causing resource waste

Engineering Contradiction:
Improveinventory management system complexityVSAvoidresource waste from expired products
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent implements preliminary verification of expiration dates during the order fulfillment process. RFID readers automatically check expiration information before products are packaged or shipped, preventing expired products from being included in orders and eliminating the need for post-shipment returns or replacements.

Inventive Principle:
Principle #10Preliminary action

AI summary

Systems and methods for managing perishable product inventory at a facility. One system includes a radio frequency identification (RFID) tag, the RFID tag associated with at least one perishable product and storing a unique identifier of the at least one perishable product. The system further includes an electronic communications device including an RFID scanner and an electronic processor. The electronic processor is configured to receive, via the RFID scanner, the unique identifier from the RFID tag, identify, from the received unique identifier, expiration information for the at least one perishable product, and perform a mitigation action in response to identifying the at least one perishable product is expired based on the expiration information.
