Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart labels for logistics systems lack the ability to monitor internal conditions such as temperature, humidity, impact, and vibration, leading to difficulties in detecting accidents like fires and theft, and have limitations in antenna performance and positioning accuracy due to their two-dimensional structure and external attachment.
Innovation Solution
A logistics smart label with a bending line design that includes both external and internal sensor units and antennas, along with a harvest module that generates power from internal and external temperature differences, allowing for comprehensive environmental monitoring and improved antenna performance through a three-dimensional antenna configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smart label is attached only to the outer surface of a logistics box, then the structure is simple and easy to install, but it cannot detect internal conditions such as temperature, humidity, impact, and vibration inside the box
Solution Approach 1:
The smart label transitions from a two-dimensional planar structure to a three-dimensional folded structure by introducing bending lines. This allows the label to extend into the interior space of the logistics box, enabling sensors to detect both external and internal environmental conditions simultaneously while maintaining a compact form factor for easy installation.
Solution Approach 2:
The smart label is divided into multiple functional regions separated by bending lines, including an external sensor area mounted on the outer surface and an internal sensor area extending into the box interior. This segmentation allows different sensor units to monitor different environments (external and internal conditions) independently while being integrated into a single label structure.
2Ease of manufacture
If a two-dimensional antenna structure is used on the smart label, then the manufacturing is simple, but the antenna performance is limited and cannot achieve uniform performance across a wide frequency band
Solution Approach 1:
The antenna structure evolves from a two-dimensional planar configuration to a three-dimensional folded architecture utilizing bending lines. This dimensional transition enables the antenna to achieve uniform performance across a wide frequency band by creating multiple radiation paths and improving impedance matching, while still being manufactured using simple printing processes on flexible substrates.
3Device complexity
If the smart label uses cell ID positioning technology without GPS reception capability, then the device complexity is reduced, but the positioning accuracy is low in many cases
Solution Approach 1:
The smart label is designed with multi-functional capabilities including GPS reception module, cell ID positioning module, and multiple sensor units (temperature, humidity, impact, vibration sensors). This universal design allows the system to automatically select the most appropriate positioning method based on availability and accuracy requirements, while also providing comprehensive environmental monitoring functions.
4Device complexity
If conventional smart labels lack harvest function, then the device complexity is low, but the operation time is limited
Solution Approach 1:
The smart label incorporates a harvest module with thermoelectric conversion elements that generate electrical energy from temperature differences between the internal and external environments of the logistics box. This self-powered capability allows the label to extend its operation time by harvesting ambient thermal energy, reducing dependence on battery replacement or recharging while maintaining relatively simple device architecture.
