Fresh Produce Transfer Priority System for Spoilage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current practices in retail stores lead to significant spoilage of fresh produce due to improper handling and refilling techniques, particularly during the transfer of produce from back-store storage to the sales floor.
Innovation Solution
A system and method that utilizes sensors and a processing system to identify and prioritize containers based on freshness data, ensuring that the containers with the shortest salability period are transferred first, and includes alerts and enforcement actions for improper transfers, along with monitoring and reordering processes to optimize stock management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If manual transfer of produce containers from back-store to sales area is performed without tracking, then operational simplicity is maintained, but produce spoilage increases due to incorrect transfer order
Solution Approach 1:
The system performs preliminary actions by assigning priority levels to containers based on freshness data before transfer occurs. The processing system pre-calculates which containers should be transferred first and stores this priority information in a database, enabling workers to simply follow predetermined transfer sequences rather than making decisions in real-time.
Solution Approach 2:
The sensor arrangement provides continuous feedback by reading container identifiers during transfer and comparing them against the priority sequence stored in the database. This feedback mechanism detects deviations from the correct transfer order and triggers enforcement actions, ensuring compliance without requiring complex real-time decision-making by workers.
2Loss of substance
If sensor arrangements and enforcement actions are implemented to monitor container transfers, then produce spoilage is reduced, but operational complexity and cost increase
Solution Approach 1:
The system employs self-service mechanisms where the sensor arrangement automatically reads container identifiers and the processing system automatically determines compliance with transfer priorities. Enforcement actions are automatically triggered without human intervention, reducing the operational burden on workers while maintaining monitoring effectiveness.
Solution Approach 2:
The patent replaces manual monitoring and decision-making processes with automated sensor-based identification and electronic processing. Instead of workers manually tracking container freshness and making transfer decisions, the system uses optical or RFID sensors to automatically read identifiers and electronic processors to determine compliance, substituting mechanical human operations with automated technological systems.
3Loss of energy
If containers are not transferred in priority order based on freshness, then transfer speed is maintained, but financial losses increase due to spoilage
Solution Approach 1:
The system introduces dynamic priority assignment where container priorities are not fixed but are determined and updated based on real-time freshness data. The processing system continuously evaluates container status and adjusts transfer priorities accordingly, creating a dynamic system that adapts to changing conditions while maintaining optimal transfer sequences.

AI summary
In a retail store having a sales area and a back-store area including a storage area, a system for managing produce includes a sensor arrangement for reading distinct identifiers associated with containers passing along a produce transfer path from the back-store area to the sales area. A processing system maintains a database including a record for each container received to the back-store area, each container record including a produce type and freshness data. For each produce type, the system determines at least one container of the given produce type in the back-store area having a shortest salability period as derived from the freshness data, this being designated a priority container, The system monitors whether containers transferred along the produce transfer path correspond to the priority containers. If a container other than a priority container is transferred, at least one enforcement action is actuated.
