Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in accurately monitoring and managing the state of logistics products during transportation, particularly in maintaining temperature, humidity, and impact conditions, which is complicated by the increasing volume of deliveries and the need for manual documentation, especially for sensitive items like vaccines.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual checking and paper certificate completion is used to monitor logistics product state, then documentation can be completed, but the process becomes time-consuming and inefficient as delivery volume increases
Solution Approach 1:
The system enables self-service monitoring where sensors automatically detect logistics product state (temperature, humidity, impact) and the system autonomously generates QR codes and electronic certificates without manual intervention. The delivery person simply needs to scan the QR code with a mobile device to access all state information, eliminating manual checking and documentation completion time.
Solution Approach 2:
The patent replaces manual mechanical processes (physically checking conditions, writing paper certificates) with automated electronic systems. Sensors electronically detect product state, a server processes data and generates QR codes, and mobile devices display information electronically. This substitution eliminates manual documentation work and significantly reduces processing time.
2Reliability
If multiple separate devices and manual processes are used to monitor different aspects of logistics product state, then comprehensive monitoring can be achieved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent merges multiple monitoring functions (temperature sensing, humidity sensing, impact detection) and multiple output processes (paper certificate generation, data recording) into a single integrated system. The server consolidates data from all sensors and generates a unified QR code containing all state information, eliminating the need for multiple separate devices and processes while maintaining comprehensive monitoring reliability.
Solution Approach 2:
The QR code serves multiple functions simultaneously: it acts as a data storage medium for all logistics state information, a communication interface between the monitoring system and users, and a verification mechanism for product condition. This multi-functionality reduces system complexity by replacing multiple specialized devices with a single universal information carrier.
3Loss of information
If detailed state information is manually recorded and stored, then data can be preserved, but information management becomes cumbersome and difficult to access
Solution Approach 1:
The system creates a digital copy of all logistics state information in the form of a QR code that can be easily stored, transmitted, and accessed. Instead of physically storing paper certificates and manually retrieving data, the electronic QR code serves as a portable digital copy that can be instantly accessed through mobile devices, significantly improving information accessibility while maintaining complete data retention.
