Location Information Distribution via Positioning Terminal Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information providing systems require pre-registration of user terminals with positioning terminals in a server, limiting the ability of general-purpose user terminals to receive location-related information without using special-purpose positioning terminals at a destination.
Innovation Solution
An information providing system comprising a first portable terminal with positioning functionality, a second portable terminal without positioning functionality, and a server that receives location identifying information from the first terminal and destination designating information from the second terminal, generates and transmits location-related information to the second terminal based on the identifying information, enabling location-related information distribution without prior registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user terminals are pre-registered with positioning terminals in a server, then location-related information can be provided to terminals with positioning function, but general-purpose user terminals without positioning function cannot receive location-related information
Solution Approach 1:
The system divides the terminal into two functional components: a positioning terminal (which can be a separate device or module) that acquires location information, and a user terminal that receives and displays location-related information. This segmentation allows user terminals without built-in positioning functions to still access location-based services by pairing with a positioning terminal.
Solution Approach 2:
The positioning terminal is designed to serve multiple functions: it can provide location information to multiple different user terminals simultaneously, and can work with various types of terminals (smartphones, tablets, computers, navigation devices) without requiring each terminal to have its own positioning function. This multi-functionality resolves the contradiction by making the positioning capability universal rather than terminal-specific.
2Ease of operation
If pre-registration mapping tables are stored in the server, then location information can be associated with specific terminals, but users must use special-purpose positioning terminals instead of general-purpose terminals
Solution Approach 1:
The system implements a feedback mechanism where the server receives location information from the positioning terminal, matches it with registered user terminal information, and sends back appropriate location-related information. This feedback loop ensures accurate information association while maintaining ease of operation, as the server automatically handles the matching process based on real-time location data rather than requiring manual pre-registration of terminal pairs.
Solution Approach 2:
The server acts as an intermediary that receives location information from positioning terminals, processes it through mapping tables, and delivers appropriate information to user terminals. This intermediary role ensures reliable information association while simplifying user operation, as users only need to have their terminal registered with the server, not manually paired with specific positioning terminals.
3Adaptability or versatility
If location-related information is provided only to registered terminals, then information accuracy can be maintained, but the system cannot serve users with general-purpose terminals at destinations
Solution Approach 1:
The system performs preliminary registration of user terminals with the server before actual use. During this preliminary action, the terminal's identification information is stored in the server's mapping table, enabling the terminal to receive location-related information later without requiring real-time registration or pairing with positioning terminals. This preliminary setup maintains information accuracy while enabling broad terminal compatibility.
Solution Approach 2:
The system creates a virtual representation of the user terminal in the server's mapping table, storing identification information that allows the server to recognize and send location-related information to the terminal. This copying approach enables general-purpose terminals to receive location information without requiring physical positioning hardware, as the terminal's identity is replicated in the server's database for information delivery.

AI summary
A positioning terminal (10) including a positioning function transmits location identifying information (IL) received from a positioning infrastructure (30), and transmits destination designating information for designating a destination of location-related information generated by an information generating unit (120) to an information providing server (100). With this arrangement, a user can receive the location-related information through a display terminal (20) not including a positioning function, without advance registration of a mapping table associating the positioning terminal (10) with the display terminal (20) in the information providing server (100). In this manner, the usability of an information providing system that provides location-related information related to locations is improved.
