Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals require frequent resetting of time, language, and location information when used in different countries, causing inconvenience to users.
Innovation Solution
A method and device that utilize GPS to obtain NMEA position messages, interpret them for current time and position, determine the corresponding nation and language, and update the terminal's setup information accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual resetting of time, language, and location information is required when traveling to different countries, then the mobile terminal can display correct local information, but the user convenience deteriorates due to the need for users to manually know and input current time, place and language information
Solution Approach 1:
The mobile terminal automatically obtains time, location, and language information through GPS and NMEA messages without requiring user input. The system self-updates setup information by interpreting GPS data and automatically determining the current nation and language, eliminating manual configuration needs while maintaining accurate local information display
Solution Approach 2:
The mobile terminal proactively obtains and processes NMEA position messages from GPS before the user needs the information. By continuously monitoring GPS data and pre-processing location information, the system prepares time, location, and language settings in advance, ensuring immediate availability without user intervention
2Ease of operation
If the mobile terminal continuously monitors GPS to automatically update setup information, then user convenience is improved, but energy consumption increases
Solution Approach 1:
The mobile terminal periodically checks for NMEA position messages from GPS rather than continuously monitoring. By using periodic polling with appropriate intervals, the system balances automatic update capability with energy conservation, activating GPS only when needed for location changes or at scheduled intervals
Solution Approach 2:
The system selectively processes only the necessary NMEA messages that contain time and position information, ignoring other GPS data. This partial processing approach reduces computational overhead and energy consumption while still achieving the goal of automatic setup information updating
