Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking systems are limited in their ability to locate tracking devices when the user's mobile device is out of range, leading to challenges in recovering lost or stolen items.
Innovation Solution
A centralized tracking system that leverages a community of users' mobile devices to detect and relay the location of a lost tracking device, using a cloud server to associate and manage user profiles and tracking device information, enabling location updates even when the user's mobile device is out of range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional tracking system using only the user's mobile device is used, then the system is simple to operate, but the tracking range is limited when the mobile device is out of range
Solution Approach 1:
The patent introduces a cloud server as an intermediary between tracking devices and user mobile devices. The cloud server receives location data from tracking devices and relays it to users, enabling tracking beyond the direct communication range of the user's mobile device. This mediator approach expands the tracking range without requiring complex changes to the tracking device itself.
Solution Approach 2:
The patent enables any electronic device with internet connectivity to function as a tracking device by integrating tracking functionality into the device's existing hardware (GPS, processor, transceiver). This universal approach allows diverse devices to perform tracking functions, expanding the effective tracking range across different device types and networks.
2Adaptability or versatility
If tracking functionality is integrated into third-party electronic devices, then the tracking range and usability are enhanced, but the device complexity and power consumption increase
Solution Approach 1:
The patent implements periodic location reporting where tracking devices transmit location data at scheduled intervals rather than continuously. The device can be configured to report location periodically (e.g., every few minutes or hours) or event-driven (e.g., when moving between geographic fences). This periodic action significantly reduces power consumption compared to continuous transmission while maintaining effective tracking capability.
Solution Approach 2:
The patent allows dynamic adjustment of tracking parameters such as reporting interval, transmission power, and GPS update frequency. These parameters can be changed based on battery status, user needs, and environmental conditions, optimizing the balance between tracking accuracy and power consumption for integrated tracking devices.
3Measurement precision
If periodic location updates are implemented, then the tracking accuracy is improved, but the energy consumption and network traffic increase
Solution Approach 1:
The system implements periodic location updates where the tracking device determines its location at scheduled intervals and transmits updates only when location changes occur or at predetermined time intervals. This approach maintains location accuracy by regularly updating the cloud server while minimizing energy consumption by keeping the device in low-power states between updates and only activating GPS and transmitters when needed.
Solution Approach 2:
The patent employs selective location reporting where the device performs full GPS location determination periodically but only transmits updates to the cloud server when location changes exceed a threshold or when specifically requested. This partial action approach maintains measurement precision for tracking purposes while reducing network traffic and energy consumption by avoiding unnecessary transmissions.

AI summary
An electronic device with a primary functionality and a tracking functionality can be used in a centralized tracking system. A controller configures the electronic device to operate in one of a set of: an “on” mode, an “off” mode, a first standby mode, and a tracking standby mode. While configured to operate in the “on” mode, the primary and tracking functionality of the electronic device are enabled, and while configured to operate in the “off” mode, both are disabled. While configured to operate in the first standby mode, the tracking functionality is enabled and the primary functionality is limited. While configured to operate in the tracking standby mode, the primary functionality is disabled but the tracking functionality is enabled, enabling the electronic device to be located while the primary functionality is disabled and saving power relative to the first standby mode and the “on” mode.
