Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional asset tracking systems fail to provide efficient and cost-effective real-time location information, especially for logistics events, leading to sub-optimal use of assets and increased operational costs due to frequent pings that drain battery life and provide unnecessary data.
Innovation Solution
An adaptive, hierarchical, context-aware wireless network system that uses reduced power profiles and proactive movement notification to associate location information with logistics events, employing sensors and actuators to detect specific movement patterns and send pings only during critical logistics events, thereby optimizing the value per ping and extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time location tracking is implemented using GPS or RFID systems, then location information is obtained, but operational costs increase and battery life is reduced due to frequent pings
Solution Approach 1:
The system implements periodic pings at extended intervals instead of continuous real-time tracking. The asset tracking device sends location information at predetermined time intervals, reducing energy consumption while still providing location data when needed. This periodic action allows the device to enter low-power states between pings, directly addressing the battery life concern.
Solution Approach 2:
The system uses motion sensors and accelerometers to detect movement patterns before a ping is sent. By preliminarily detecting whether the asset has moved since the last ping, the system can intelligently determine when location information is actually needed, avoiding unnecessary pings and further reducing energy consumption.
2Loss of information
If frequent pings are sent to obtain real-time location data, then location status is updated continuously, but operational costs increase and unnecessary data is transmitted
Solution Approach 1:
The system incorporates feedback mechanisms where motion sensors continuously monitor asset movement and provide input to the ping decision logic. This feedback loop allows the system to adjust ping frequency dynamically based on actual asset status changes, ensuring location information is transmitted only when meaningful changes occur, thus reducing unnecessary data transmission and operational costs.
Solution Approach 2:
The system dynamically adjusts the ping frequency and power consumption levels based on detected movement patterns and asset status. Rather than using a fixed periodic schedule, the system adapts its behavior in real-time, increasing activity when movement is detected and entering low-power modes when the asset is stationary, optimizing the balance between information quality and energy consumption.
3Loss of information
If sensor-based tracking systems are used to provide detailed location and condition information, then comprehensive asset data is obtained, but system complexity and cost increase significantly
Solution Approach 1:
The system extracts only the essential location and movement information needed for tracking purposes using simple motion sensors and accelerometers, rather than implementing comprehensive sensor-based monitoring of all asset conditions. This extraction approach focuses on obtaining the critical data points (location changes, movement patterns) while eliminating unnecessary sensors and processing complexity.
Solution Approach 2:
The system uses inexpensive motion detection sensors and basic RFID/GPS components rather than expensive, complex sensor arrays. The approach accepts that individual sensor components have limited functionality but compensates through intelligent processing and periodic updates, achieving adequate tracking capability at lower system complexity and cost.

AI summary
A method of determining locations of tracking devices may include receiving a data ping from a tracking device, where the data ping may be sent in response to the tracking device detecting a predetermined sequence of movements indicating a logistic event from a plurality of predefined logistics events. The method may additionally include accessing a hierarchical logistics flow for the tracking device, where the hierarchical logistics flow may include an ordered sequential list of event sites through which the tracking device is likely to move. The method may further include assigning an event site from the ordered sequential list of event sites based on the logistic event and the hierarchical logistics flow.
