Position Search System Automatic Application Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position search systems for pets, children, and valuables face challenges in increasing the number of communication terminals used for finding tags while reducing the processing load on volunteers, as the activation and deactivation of dedicated applications are complex and often forgotten, leading to reduced volunteer cooperation due to high battery consumption and installation costs.
Innovation Solution
A position search system that links the position recording application with the position search application, allowing the position search application to automatically start and end based on the user's outdoor activities, using GPS only when necessary, thereby reducing the need for manual activation and deactivation by volunteers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dedicated position search application is activated continuously to increase the number of communication terminals available for finding tags, then the probability of finding the tag is improved, but the battery consumption increases and volunteers are reluctant to activate the application
Solution Approach 1:
The system performs preliminary action by automatically activating the position search application when the communication terminal detects that the user is outdoors, before the user needs to search for a tag. This eliminates the need for manual activation while ensuring the application is ready when needed, thereby maintaining high reliability without requiring volunteers to manually activate the application continuously
Solution Approach 2:
The communication terminal performs self-service by automatically detecting whether the user is outdoors and autonomously activating or deactivating the position search application based on this detection. This eliminates the need for user intervention in the activation process, reducing the burden on volunteers while maintaining the application's availability when needed
2Reliability
If the communication terminals are arranged across the town to increase coverage for finding tags, then the probability of finding the tag is improved, but the installation cost and maintenance cost increase
Solution Approach 1:
The system leverages the universal functionality of existing communication terminals (smartphones) that citizens already carry. Instead of installing dedicated position search terminals across the town, the system enables any communication terminal with a position search application to function as a search node. This approach maintains wide coverage and high probability of finding tags while eliminating the need for dedicated infrastructure installation and maintenance
Solution Approach 2:
The system creates virtual copies of position search functionality through software installation on existing devices rather than deploying physical terminals. By installing the position search application on citizens' communication terminals, the system replicates the functionality of dedicated search terminals without the associated hardware costs and maintenance requirements
3Ease of manufacture
If the position search application is activated manually by volunteers to reduce government load, then the operating cost is reduced, but the activation and deactivation process is complex and often forgotten
Solution Approach 1:
The system implements self-service by having the communication terminal automatically detect outdoor conditions and activate the position search application without user intervention. The terminal monitors its own state and autonomously manages the application activation, eliminating the complex manual activation process that volunteers would need to perform and remember
Solution Approach 2:
The system uses feedback from the terminal's own state (whether the user is outdoors or indoors) to automatically control the application activation. The terminal continuously monitors its environment and uses this feedback information to decide when to activate or deactivate the position search application, creating a closed-loop system that eliminates manual operation

Function Achieved in This Case
This approach increases the number of communication terminals available for finding tags without increasing the load on volunteers, improving the probability of finding the tag by automating the activation and deactivation processes and reducing battery consumption.
Implementation Method 1
a tag that sends a tag signal including identification information
Implementation Method 2
a first communication terminal that receives the tag signal
Implementation Method 3
perform a detection process of detecting a position of the first communication terminal
Data Source
AI summary
A position search system includes a tag that sends a tag signal including identification information, a first communication terminal that receives the tag signal, a server that collects pieces of information from the first communication terminal that has received the tag signal, and a second communication terminal that acquires positional information on the tag transmitted from the server. The first communication terminal includes first processing circuitry configured to perform a detection process of detecting a position of the first communication terminal when a possessor of the first communication terminal goes out of doors, perform a reception process of receiving the tag signal that has been sent from the tag, and perform a notification process of notifying the server of both identification information on the tag included in the tag signal received from the tag and positional information on the first communication terminal obtained when the tag signal has been received.
