Automated Arrival Notification via Geofence Timer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based notification systems require users to pre-select a destination location, which is burdensome and limits their effectiveness when the destination is unknown, preventing timely arrival alerts.
Innovation Solution
A system that automatically defines a geofence around a device's current location and sets a timer, considering exceptions and preferences to avoid false positives, allowing for notifications upon arrival without pre-selecting a destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user specifies a destination location in advance, then the device can accurately determine arrival, but the system becomes burdensome and ineffective when the destination is unknown
Solution Approach 1:
The system automatically detects arrival by monitoring when the device remains stationary within a geofence for a predetermined time period, eliminating the need for users to manually specify destinations. The device serves itself by autonomously determining arrival based on location data and time thresholds.
Solution Approach 2:
The system pre-establishes geofences around locations of interest before arrival occurs. By setting up these virtual boundaries in advance and monitoring device presence within them, the system prepares the detection framework proactively rather than requiring reactive destination input.
2Reliability
If the system requires pre-selection of destination, then arrival can be determined, but timely arrival alerts cannot be provided when destination is not known in advance
Solution Approach 1:
The device autonomously monitors its own location and automatically triggers arrival notifications without requiring pre-configured destinations. The system detects when the device has been stationary for the predetermined time period and sends notifications promptly, eliminating delays associated with manual destination selection.
Solution Approach 2:
The system dynamically adjusts to real-time location data rather than relying on static pre-selected destinations. By continuously monitoring device position and calculating stationary duration, the system adapts to unknown destinations as they occur, providing timely alerts without requiring advance configuration.
3Extent of automation
If a geofence is continually defined around device location, then automatic arrival detection is enabled, but false positives may occur without exceptions and preferences
Solution Approach 1:
The system incorporates feedback mechanisms by considering exceptions and preferences when evaluating arrival conditions. It analyzes multiple factors including stationary duration, geofence boundaries, and user-defined exceptions to confirm true arrivals, reducing false positives through iterative verification.
Solution Approach 2:
The system changes multiple parameters simultaneously to confirm arrival: stationary duration must exceed a threshold, device must remain within geofence boundaries, and location must not match exception criteria. By requiring simultaneous satisfaction of multiple parameter conditions, the system reliably distinguishes true arrivals from false positives.

AI summary
A device's arrival at a destination location is automatically detected, and notification of such arrival is automatically generated, without any need for a user to specify the destination location in advance. A perimeter, or geofence, is continually or periodically defined around the device's current location. A timer is automatically set, with some pre-specified duration. If the device exits the geofence before the timer expires, the new location of the device is determined, a new geofence around that location is defined, and the timer is reset. If the timer expires before the device exits the geofence, the device is considered to have arrived at a destination; an “arrives” event is generated. Notification of such an event can be output at the device and/or transmitted to one or more subscribers. Various exceptions, conditions, and preferences can be taken into account so as to avoid false positives.
