Navigation Terminal Destination Setting via Position Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in setting a destination in navigation systems when they do not know the correct address or geographical position, especially when the destination is a specific feature like a highway or mountain slope.
Innovation Solution
A method and apparatus that utilize position information messages to set destination coordinates, allowing users to receive and process position information via wireless communication, enabling correct destination setting even without specific address knowledge, using a combination of mobile communication terminals and exclusive navigation terminals for route calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly input address or search stored map data to set destination, then destination coordinates can be set, but users cannot set destination when they do not know the correct address or geographical position
Solution Approach 1:
The patent introduces position information messages as an intermediary carrier that transmits destination coordinates without requiring user knowledge of addresses. The message acts as a mediator between the desired destination and the navigation system, allowing users to set destinations by receiving position information through communication protocols rather than through traditional address input methods.
Solution Approach 2:
The patent replaces the mechanical interaction of manual address input and map searching with an automated electronic message-based system. Position information messages containing coordinates are transmitted via communication protocols, substituting the manual mechanical process of typing addresses or navigating map interfaces with an automated electronic delivery system that directly provides destination coordinates.
2Measurement precision
If users manually input destination coordinates, then accurate destination setting is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-calculating and embedding accurate position coordinates within position information messages before transmission. The destination coordinates are prepared in advance by the message sender or system, eliminating the need for users to perform time-consuming manual input or search operations at the moment of destination setting.
Solution Approach 2:
The system enables self-service by automatically receiving, parsing, and applying position coordinates from incoming messages without requiring user intervention for coordinate input. The navigation terminal autonomously extracts destination information from the message format and configures the route calculation, freeing users from the tedious task of manual coordinate entry while maintaining high precision.
Data Source
AI summary
A method and apparatus are provided for setting a desired destination in a navigation terminal. A position information message is received. Position coordinates corresponding to the position information included in the position information message are set as the position coordinates of a desired destination related to a certain route.
