Sensor Device for Real-Time Logistics Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracking systems, such as bar codes and RFID tags, are inadequate for providing real-time monitoring of package conditions like temperature, humidity, and location during transportation, as they require manual scanning and lack environmental data, which is essential for quality control and efficient asset management.
Innovation Solution
A sensor device equipped with sensors for detecting light, temperature, humidity, pressure, and acceleration, along with a memory for data storage, which can transmit data wirelessly and operate autonomously to provide real-time monitoring of package conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bar codes are used for tracking items, then basic tracking capability is achieved, but manual scanning is required which reduces productivity
Solution Approach 1:
The tracking system performs automatic identification and data collection without requiring manual scanning operations. RFID tags and sensors autonomously transmit information to readers, eliminating the need for human operators to manually scan each item, thereby significantly improving productivity in logistics and inventory management
2Loss of information
If RFID tags are used for tracking items, then automatic tracking is achieved, but environmental condition monitoring is not provided
Solution Approach 1:
The patent combines RFID tracking functionality with environmental sensing capabilities into a single integrated system. RFID tags are merged with temperature, humidity, light, and other environmental sensors to simultaneously provide location tracking and environmental condition monitoring, preventing information loss about package conditions during transportation
Solution Approach 2:
The tracking device is designed with multi-functionality, serving both as an RFID identification tag for location tracking and as an environmental monitoring station. This universal device can track items while simultaneously monitoring temperature, humidity, light exposure, and other environmental factors, enhancing versatility without requiring separate systems
3Reliability
If sensor-based tracking systems are used, then environmental monitoring is provided, but the systems are expensive and provide extraneous information
Solution Approach 1:
The system implements selective environmental monitoring by deploying sensors only for the specific environmental parameters that are critical for the particular goods being transported. Rather than monitoring all possible environmental factors, the system activates only the necessary sensors (e.g., temperature sensors for pharmaceuticals, humidity sensors for agricultural products), reducing costs while maintaining reliability for quality control
Solution Approach 2:
The patent applies different monitoring configurations to different locations and types of goods within the logistics network. High-value or sensitive items receive comprehensive environmental monitoring, while standard items use basic tracking. This localized approach to quality control ensures reliability where needed while minimizing unnecessary costs and extraneous information collection
