Geospatial Lost Device Detection via Proximity Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network systems for transportation services, users often inadvertently leave items in provider vehicles at the end of a trip, leading to inefficiencies as providers must return lost items, reducing their capacity to serve other users.
Innovation Solution
A network system that compares the geospatial locations of user and provider client devices during and after a service to detect lost devices, using periodic location transmissions and sensor data to determine proximity and alert users and providers of lost items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If providers manually track and return lost items after trips, then lost items can be recovered, but provider productivity decreases due to unnecessary return trips
Solution Approach 1:
The system performs preliminary actions by continuously monitoring device proximity during and after trips, and automatically detecting when items are left behind before providers complete their return journey. This early detection prevents the need for separate return trips, as providers can immediately notify users and proceed with their next service requests.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring geospatial location data and device proximity status, then providing real-time notifications to both providers and users when lost items are detected. This closed-loop feedback system enables rapid response without requiring manual tracking or confirmation from providers.
2Reliability
If users rely on providers to bring lost items to specific locations, then lost items are returned, but time is lost due to coordination and travel delays
Solution Approach 1:
The system performs preliminary detection and notification actions automatically, identifying lost items and alerting both providers and users before the provider completes their trip. This preliminary action eliminates the need for post-trip coordination and travel to retrieve items, as users are notified while the provider is still en route or at the destination.
Solution Approach 2:
The system enables self-service by automatically detecting lost items through geospatial monitoring and autonomously notifying both parties involved. Users receive automated alerts with location information, eliminating the need for manual reporting or coordination with providers, thereby reducing retrieval time significantly.
3Reliability
If providers hold onto lost items until returned, then items are secured, but resource efficiency decreases as providers cannot fulfill other service requests
Solution Approach 1:
The system performs preliminary detection during and immediately after trips, identifying lost items before providers need to hold onto them. By detecting items early through continuous geospatial monitoring, the system enables providers to notify users and release their obligation to hold items, allowing them to proceed with other service requests without compromising item security.
Solution Approach 2:
The system implements real-time feedback by continuously monitoring device proximity and automatically notifying providers and users when items are detected as lost. This immediate feedback eliminates the need for providers to manually hold onto items, as the automated notification system ensures items are reported and coordinated for return, freeing providers to fulfill other service requests.

AI summary
A network system detects lost client devices based on a comparison of geospatial locations transmitted by user and provider client devices during and after a service. The network system assigns a service status indicating that a service from a start location to a destination location is in progress and monitors the locations of the user and provider client devices during the duration of the service and for a specified period of time after the service ends. In response to determining that the user and provider client devices remain in proximity to each other after the service has ended, the network system notifies the user of the lost device.
