Supply Chain Sensor Network For Product Freshness Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product supply chains face challenges in tracking the freshness of perishable products across various distribution paths, from farm to fork, and in assessing whether products have been compromised, leading to issues with spoilage and additional delivery costs.
Innovation Solution
A product supply chain monitoring system utilizing sensors with unique identifiers (UIDs) to measure environmental data, calculate product degradation values, and generate alerts when these values exceed thresholds, enabling operators to take remedial actions to prevent further loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tracking methods are used for supply chain monitoring, then device complexity is reduced, but measurement precision of product freshness and environmental conditions deteriorates
Solution Approach 1:
The monitoring system is segmented into multiple independent sensors (temperature, humidity, light, motion detectors) distributed throughout the supply chain. Each sensor independently measures specific environmental parameters and transmits data to a central system, enabling precise environmental monitoring without requiring a single complex device
Solution Approach 2:
The system employs multi-functional sensors that can detect multiple environmental parameters (temperature, humidity, light, motion) simultaneously. This universal approach allows comprehensive product freshness assessment using standardized sensor technology rather than requiring specialized complex equipment for each measurement type
2Measurement precision
If continuous environmental monitoring is implemented throughout the supply chain, then product freshness assessment improves, but loss of time in data collection and processing increases
Solution Approach 1:
Environmental conditions are continuously monitored and data is collected in advance throughout the supply chain journey. The system proactively tracks temperature, humidity, and other parameters from production through distribution, so that product freshness can be assessed immediately upon arrival without delayed measurements
Solution Approach 2:
The system implements real-time feedback loops where sensor data is continuously transmitted to the central monitoring system, which immediately processes the information and generates alerts when environmental thresholds are exceeded. This continuous feedback mechanism eliminates batch processing delays and enables immediate response to freshness concerns
3Reliability
If multiple sensors with unique identifiers are deployed to track product conditions, then reliability of freshness assessment improves, but device complexity increases
Solution Approach 1:
Each sensor in the network is equipped with a unique identifier and autonomously transmits its own data to the central system without requiring manual configuration or management. The sensors self-manage their identification and data reporting functions, enabling reliable multi-point monitoring while minimizing the complexity of sensor network management
Solution Approach 2:
The central monitoring system acts as an intermediary that receives, processes, and correlates data from multiple independent sensors. This intermediary layer simplifies the management complexity by providing a single point of data aggregation and analysis, while the individual sensors remain simple, independent units with unique identifiers

AI summary
An environment monitoring method including measuring data from a plurality of sensors, wherein each of the plurality of sensors includes a unique identifier (UID). The method further includes instructing each of the plurality of sensors to measure data. The method also includes receiving the measured data from each of the plurality of sensors. The method then calculates a product degradation value of a product based on the measured data and compares the product degradation value with a threshold product degradation value. In response to the product degradation value of the product exceeding the threshold produce degradation value, the method generates and sends an alert to a device.
