Food Freshness Monitoring With Sensor Alerts and Item Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget about food items in storage devices, leading to spoilage, and have difficulty locating or replacing them, resulting in inefficiencies and waste.
Innovation Solution
A food storage device equipped with sensors and visual display indicators that notify users of spoilage through color changes, audio alerts, and inventory management, connected to services for barcode scanning and shopping assistance, to track and manage food freshness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If food storage devices are used to store more food items, then food storage capacity increases, but users have difficulty tracking and locating items, leading to spoilage and waste
Solution Approach 1:
The system continuously monitors food items using sensors and provides real-time feedback to users through a user interface. The food freshness management engine tracks the state of food items, detects changes (such as temperature variations or expiration), and communicates this information back to users, enabling them to take timely action before spoilage occurs.
Solution Approach 2:
The patent introduces an intermediary system consisting of sensors, a food freshness management engine, and a user interface that mediates between the stored food items and users. This intermediary layer automatically tracks, monitors, and communicates food item status without requiring direct user intervention, thus solving the information loss problem while maintaining high storage capacity.
2Reliability
If manual monitoring of food items is performed, then users can track freshness, but users often forget about food items leading to spoilage
Solution Approach 1:
The system enables self-service monitoring where the food storage device automatically tracks and monitors its own contents. Sensors continuously detect food item status, the management engine processes this data, and the system autonomously determines when items are approaching expiration or have spoiled, eliminating the need for users to manually check and reducing reliance on human memory.
Solution Approach 2:
The monitoring system operates continuously without interruption, constantly tracking food item freshness, temperature, and other relevant parameters. This continuous monitoring ensures that no food item is overlooked or forgotten, maintaining reliable tracking over extended periods without requiring user intervention.
3Loss of information
If visual display indicators are added to notify users of spoilage, then food freshness notification improves, but device complexity increases
Solution Approach 1:
The system employs visual display indicators that utilize color changes to communicate food freshness status to users. Different colors represent different freshness states (e.g., green for fresh, yellow for approaching expiration, red for spoiled), providing intuitive and immediate information communication without requiring complex interfaces or user interpretation.
Data Source
AI summary
Disclosed aspects relate to food freshness management. A freshness triggering event may be identified for a food item. The freshness triggering event may indicate that a criterion related to the food item has been achieved. A food freshness management action may be determined. The food freshness management action may be determined to respond to the freshness triggering event for the food item. The food freshness management action may be initiated. The food freshness management action may be carried-out with respect to the freshness triggering event for the food item.
