Terminal Position Sharing for Navigation Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GPS navigation systems require drivers to input destination addresses, which can be unsafe while driving and may provide incorrect routes if map data is not updated, leading to inefficiencies and potential accidents.
Innovation Solution
A system where a first terminal apparatus shares position information with a second terminal apparatus, allowing the second apparatus to generate and display navigation information, including routes, based on the received position information, enabling users to reach destinations without manual input and ensuring updated route information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver inputs destination address into GPS navigation unit, then the navigation unit can provide routes to destination, but the driver cannot focus on driving and is exposed to accident risk
Solution Approach 1:
The system performs preliminary action by having the passenger input the destination address before the driving process begins. The navigation system is pre-configured with the destination information, so the driver does not need to interact with the device during driving. This eliminates the distraction hazard while maintaining full navigation functionality.
Solution Approach 2:
The patent introduces an intermediary role (passenger) who handles the destination input task. The passenger acts as a mediator between the navigation system and the driver, taking on the responsibility of operating the device while the driver focuses on safe operation of the vehicle.
2Reliability
If GPS navigation unit uses old map data, then the device structure remains simple and updates are minimized, but the navigation unit provides incorrect information and cannot utilize new roads
Solution Approach 1:
The system implements feedback by allowing users to report new roads and construction information. This user-generated feedback creates a crowd-sourced update mechanism where real-world observations are transmitted back to the system, enabling map data to be updated with new road information without requiring complex automated detection systems.
Solution Approach 2:
The system employs self-service through user-submitted construction and road information. Users actively contribute to updating the map data by reporting new roads and infrastructure changes they observe, creating a decentralized, community-driven approach to maintaining current navigation information.
3Productivity
If map data is not updated regularly, then maintenance cost and complexity are reduced, but the navigation unit cannot provide efficient routes using recently-constructed roads
Solution Approach 1:
The system performs preliminary action by collecting and storing user-submitted construction and road information as it becomes available. Rather than waiting for formal map updates, the system proactively accumulates data about new roads and infrastructure, preparing it for immediate use in route calculations to maintain high travel efficiency.

AI summary
A terminal apparatus, a method and a system for setting up a destination and providing information are provided, in which the terminal apparatus includes a communicator which is configured to communicate with other terminal apparatuses, an input unit which is configured to receive a user command, a display which is configured to display a list including at least one item which corresponds to at least one of the other terminal apparatuses, and a controller which is configured to control the communicator to transmit destination information to a first terminal apparatus which corresponds to a selected item that is selected from among the at least one item included in the displayed list via the input unit. Accordingly, a user is provided with routes to the destination, without having to input address or name of the intended destination on his own terminal apparatus.
