Solution Overview
Problem
Existing map display devices in navigation systems face challenges in promptly and efficiently superimposing weather information over a map, particularly in allocating and displaying weather data for multiple regions on a divided display screen.
Innovation Solution
A map display device with a display monitor divided into split areas, a reception unit for receiving weather information, an information extraction unit that calculates geographical positions and allocates weather information to corresponding areas, and a display control unit for rapid display of weather data, including wind direction, wind strength, temperature, and precipitation, using a satellite radio broadcast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If weather information is received and displayed for multiple regions simultaneously, then the completeness of weather information is improved, but the processing time and system complexity increase
Solution Approach 1:
The display screen is divided into multiple split areas (e.g., 3x5 grid = 15 areas), and weather information is received and processed separately for each region corresponding to these split areas. This segmentation allows parallel processing of weather information for different regions, reducing overall processing time while maintaining comprehensive coverage.
Solution Approach 2:
The system pre-divides the weather information-available geographical range into multiple regions corresponding to the split areas before displaying the map. This preliminary organization of weather data by region enables efficient extraction and allocation without requiring real-time processing of the entire weather dataset, thus reducing processing time.
2Measurement precision
If the display screen is divided into multiple split areas for weather information display, then the accuracy of weather information allocation is improved, but the device complexity increases
Solution Approach 1:
The display screen is segmented into multiple split areas, and the weather information geographical range is segmented into corresponding regions. This segmentation enables precise allocation of weather information to specific display areas through a systematic mapping process, improving accuracy while managing complexity through structured division.
Solution Approach 2:
The same split area division structure serves multiple functions: it organizes the display layout, defines weather information regions, and provides the basis for geographical position calculation. This multi-functionality reduces the need for separate complex systems, thereby managing device complexity while maintaining allocation accuracy.
3Speed
If weather information is extracted and allocated to split areas based on geographical positions, then the speed of weather information display is improved, but the calculation complexity increases
Solution Approach 1:
The system pre-calculates and stores the geographical positions corresponding to the centers of split areas before the weather information extraction process. This preliminary preparation eliminates the need for complex real-time calculations during weather data processing, significantly improving display speed while reducing computational complexity during the critical weather information extraction phase.
Solution Approach 2:
The system uses pre-calculated geographical position data as an intermediary between the split area display structure and the weather information extraction process. This intermediary approach simplifies the matching process between weather regions and display areas, improving processing speed without requiring complex real-time calculations.
