Portable Device Location via Multi-Device Wireless Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often ignore prompts from their mobile terminals when their portable devices go missing, leading to them being too far away to be found when they realize the loss, as existing methods lack effective location determination and assistance mechanisms.
Innovation Solution
A method and apparatus that receive a location searching request for a target portable device, acquire location information from another device that detected a wireless signal of the target device, and send a location indicating message to a communication terminal bound with the target device, optionally including account identification for assistance and time information for improved accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal sends a prompt message to remind the user about the lost electronic device, then the user can be notified about the lost device, but the user often ignores the prompt message and the device is lost permanently
Solution Approach 1:
The system establishes a feedback loop where location information is continuously collected from multiple devices and fed back to the user's mobile terminal. This continuous feedback mechanism ensures the user is repeatedly informed about the device's location, increasing the likelihood of user response and device recovery.
Solution Approach 2:
The system performs preliminary actions by proactively collecting location information from multiple devices before the user realizes their device is lost. This advance preparation ensures that when the user does notice the loss, location data is already available and can be immediately provided to assist recovery.
2Measurement precision
If the mobile terminal determines distance based on wireless signal strength, then the device can provide location information, but the distance calculation becomes inaccurate when the user is too far away
Solution Approach 1:
The system segments the location determination task by using multiple independent devices (smartwatches, smartphones, tablets) to collectively track the lost device's location. Each device independently measures distance and transmits its data, allowing the system to aggregate information from multiple sources to achieve accurate location determination even when individual devices are far from the target.
Solution Approach 2:
The system transitions from single-point distance measurement to multi-point spatial mapping by collecting location data from multiple devices at different positions. This dimensional expansion allows the system to triangulate the device's location more accurately and provide real-time location information even when the user is distant from the lost device.
