Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring the safety and quality of consumable products throughout the global supply chain is challenging due to various sources of contamination, including water, air, equipment, and biological materials, which can lead to spoilage and foodborne illnesses.
Innovation Solution
The implementation of a monitoring system that utilizes sensors embedded or attached to materials, packaging, and equipment to detect and track chemicals, analytes, and other unwanted factors in real-time, generating alerts when predetermined profiles are detected, and providing data for analytics dashboards to guide decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are embedded or attached to materials, packaging, and equipment throughout the supply chain, then real-time detection capability is improved, but device complexity and implementation cost increase
Solution Approach 1:
The monitoring system is divided into multiple independent sensor units that can be individually attached to different materials, packaging, and equipment throughout the supply chain. Each sensor unit operates independently but communicates data to a centralized platform, allowing real-time detection without requiring a completely integrated complex system.
Solution Approach 2:
The sensor system is designed to detect multiple types of contaminants (chemical, biological, physical) using a universal platform that can be applied across different supply chain stages. This multi-functional approach reduces overall system complexity by using standardized sensor units rather than specialized detectors for each contaminant type.
2Reliability
If comprehensive monitoring of chemicals and contaminants is implemented throughout the supply chain, then product safety is improved, but loss of time and operational efficiency decrease
Solution Approach 1:
The monitoring system operates continuously throughout the supply chain without interrupting normal operations. Sensors continuously detect contaminants and transmit data in real-time, allowing safety monitoring to occur alongside production and logistics activities rather than requiring separate inspection periods.
Solution Approach 2:
The system provides immediate feedback when contaminants are detected, allowing for rapid response and corrective action. This real-time feedback mechanism enables the system to maintain high product safety while minimizing operational disruptions, as issues are addressed promptly rather than through lengthy inspection and testing processes.
3Speed
If real-time alerting systems are implemented to detect predetermined contaminant profiles, then response time to contamination is improved, but use of energy and operational costs increase
Solution Approach 1:
The alerting system uses periodic sampling and threshold-based detection rather than continuous high-power transmission. Sensors monitor contaminant levels continuously at low power and only activate full alerting and communication functions when predetermined contaminant profiles are detected, reducing overall energy consumption while maintaining rapid response capability.
