Portable Terminal Sketch Map Generation for Route Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals lack the ability to generate and share route point information, making it difficult for users without navigation functions to determine and follow routes to destinations, leading to inconvenience in coordinating meetings or visits.
Innovation Solution
An apparatus and method in a portable terminal that collects location information, generates a sketch map message including route information, and shares it with another user, utilizing a control unit, satellite signal receiving module, and communication unit to enable route sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If navigation function is not provided in portable terminal, then device complexity is reduced, but route information cannot be shared with other users
Solution Approach 1:
The patent extracts only the essential route information generation and sharing capability from the complete navigation function. Instead of implementing full navigation with map display and turn-by-turn directions, the system extracts the core function of collecting location information and generating sketch map messages that can be shared via SMS, thereby reducing device complexity while maintaining route information sharing capability
Solution Approach 2:
The patent creates a simplified copy of navigation functionality by generating sketch map messages that represent route information in a text-based format suitable for SMS transmission. This copy contains the essential route point information without requiring full navigation software, enabling route sharing on basic portable terminals
2Loss of time
If route information is not shared with users without navigation function, then communication overhead is reduced, but user convenience deteriorates
Solution Approach 1:
The patent implements preliminary action by automatically collecting location information and generating sketch map messages in advance. The system proactively creates the route information message that can be sent to the recipient, eliminating the need for back-and-forth communication to exchange route details. The message is prepared with all necessary route point information before transmission
Solution Approach 2:
The patent introduces SMS messaging as an intermediary medium to transfer route information between users. Instead of requiring direct communication or both parties to have navigation functions, the sketch map message serves as an intermediary carrier that conveys essential route information from the sender to the recipient, simplifying the interaction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users of portable terminals without navigation functions to easily access destinations by sharing route information, reducing the need for continuous communication and enhancing convenience in navigating to scheduled locations.
Implementation Method 1
a satellite signal receiving module configured to receive a satellite signal. A sketch map generating unit detects/stores the current location of the portable terminal by using the satellite signal
Data Source
AI summary
Provided is an apparatus and method for generating a sketch map in a portable terminal. The apparatus includes a sketch map generating unit. The sketch map generating unit collects information about route points of the portable terminal by using location information, generates a sketch map message including the route information, and shares the generated sketch map message with another user.
