Portable Locator Arrival Alert System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Children facing separation from their guardians in public places, especially when unfamiliar with their surroundings, face challenges in communicating their location effectively, leading to inefficient search processes when they go missing.
Innovation Solution
A method and system that utilizes a portable locator to transmit position information to a server, which analyzes the data to determine stay areas and estimated arrival times, triggering reminders if the child does not arrive at expected locations within set times, ensuring the guardian's awareness of the child's safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a child sends a short message or initiates a voice call to the guardian to communicate position information, then the guardian can receive some location data, but it is very difficult to clearly describe the current position information as the child is not familiar with the ambient surrounding
Solution Approach 1:
The portable locator automatically obtains and transmits position information without requiring the child to manually describe their location. The device serves itself by autonomously capturing GPS coordinates and sending them to the guardian, eliminating the need for the child to understand or articulate their surroundings.
Solution Approach 2:
The patent replaces the mechanical/manual method of a child verbally describing their location with an automated electronic positioning system. The GPS receiver and transmitter components automatically determine and communicate position data, substituting human cognitive effort with technological automation.
2Productivity
If the guardian resorts to news media or government authority to search for the child, then the search can be expanded to broader channels, but the person search effectiveness is undesirable due to time loss and lack of real-time location data
Solution Approach 1:
The system establishes continuous feedback loops where the portable locator periodically transmits position information to the server, which then relays updates to the guardian. This real-time feedback mechanism allows the guardian to track the child's location dynamically without initiating external search procedures.
Solution Approach 2:
The portable locator continuously obtains and transmits position information before any emergency occurs. The system is already active and collecting data, so when a child goes missing, the guardian immediately has access to the most recent location information without needing to start search procedures from scratch.
3Reliability
If the portable locator continuously transmits position information to the server, then the guardian can monitor the child's location in real-time, but energy consumption increases
Solution Approach 1:
The portable locator transmits position information at periodic intervals rather than continuously. The GPS receiver obtains location data and the transmitter sends updates at predetermined time intervals, reducing energy consumption while maintaining adequate monitoring capability for the guardian.

AI summary
The present invention discloses a method, device, and system for prompting whether a portable locator has arrived on time, one of which comprising: a server, according to position point information transmitted by the portable locator, judges that there is not a position point indicative of arrival at a destination reminder area in a current preset time period and the current time has already exceeded an estimated arrival time, and then generates and issues a non-arrival reminder. By employing the present invention, the guardian confirms at any time that the monitored person carrying the portable locator does not arrive at the destination reminder area within the preset arrival time, and thereby masters the safety information of the monitored person, whereby the user experience is improved and subsequent person search effectiveness is enhanced.
