Printed Asset Tracker Antenna for Continuous Logistics Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking devices are costly, cumbersome, and limited in tracking capabilities, with high operational costs and logistical challenges such as device rotation and battery replacement, and passive RFID tags provide only gate-level tracking without visibility during transportation.
Innovation Solution
A printable tracking device comprising an antenna formed on a carrier, such as cardboard, which is attachable to an asset and determines position estimates using observable radio signals, enabling active tracking throughout logistics chains without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tracking devices are used, then tracking capabilities are provided, but production and operational costs are high
Solution Approach 1:
The patent applies the disposable principle by designing a tracking device that is intentionally made inexpensive through printed antenna technology and simplified construction. The device is intended for single-use on each asset, eliminating the need for expensive, reusable hardware. After the asset reaches its destination, the tracker is discarded rather than recovered or reused, which simplifies the overall system architecture and reduces per-unit costs.
Solution Approach 2:
The patent changes the fundamental parameter of antenna construction from traditional wired or molded methods to printed circuit board (PCB) technology. This parameter change enables mass production at lower costs, reduces material usage, and allows for integration directly onto the asset surface. The printed antenna approach transforms the manufacturing process from complex assembly to simpler printing and attachment operations.
2Duration of action of moving object
If tracking devices with battery life are used, then continuous tracking is enabled, but battery replacement operations are required
Solution Approach 1:
The patent resolves the battery replacement issue by embracing the disposable concept. Instead of designing for long battery life requiring periodic maintenance, the device is engineered with sufficient battery capacity to last the entire duration of a single asset journey. The tracker is replaced only when the asset changes, eliminating all battery maintenance operations. This approach trades device longevity for operational simplicity and eliminates the productivity loss from maintenance activities.
3Ease of manufacture
If passive RFID tags are used, then cost is reduced, but tracking visibility is limited to gate level only
Solution Approach 1:
The patent merges the low cost advantage of passive RFID with the active tracking capabilities of battery-powered devices. By combining a printed antenna (enabling active transmission) with a compact battery and minimal electronics, the device achieves continuous location reporting throughout the logistics chain rather than only at gate points. This fusion maintains affordability while eliminating the information gaps present in pure passive RFID systems.
