Solution Overview

Problem

Existing weather station systems face challenges in providing accurate weather estimates at specific locations due to the abundance of weather data from numerous stations, leading to inefficiencies and potential inaccuracies in weather reporting and navigation.

Innovation Solution

A method is developed to select a subset of weather stations based on their average distance and location relative to a specific location, using weighted averages and predefined criteria, to optimize weather data collection and reduce computational complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If weather data is collected from all available weather stations, then the quantity of weather information increases, but the accuracy of weather estimation at a specific location deteriorates due to inclusion of irrelevant distant station data

Engineering Contradiction:
Improvequantity of weather informationVSAvoidaccuracy of weather estimation
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent segments the set of all weather stations into a selected subset based on their spatial relationship to the target location. By dividing the complete dataset into relevant and irrelevant portions, the system processes only the segmented subset that contributes to accurate local weather estimation, thereby maintaining data quantity benefits while eliminating precision-deteriorating elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by selecting weather stations based on their proximity and spatial distribution relative to the specific location of interest. Different locations will have different optimal subsets of weather stations, allowing the system to tailor the data source composition to local conditions, thus improving estimation accuracy without sacrificing the overall quantity of available weather information.

Inventive Principle:
Principle #3Local quality

2Reliability

If a large number of weather stations are used for weather estimation, then the completeness of weather data improves, but the computational complexity increases due to processing numerous station combinations

Engineering Contradiction:
Improvecompleteness of weather dataVSAvoidcomputational complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the necessary subset of weather stations required for accurate local weather estimation, removing redundant distant stations from the processing pipeline. This extraction maintains the reliability and completeness of weather data for the specific location while significantly reducing the computational complexity associated with evaluating all possible station combinations.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs partial action by selecting a specific number and configuration of weather stations that is sufficient for accurate estimation rather than using all available stations. The system determines the optimal subset size and composition, performing just enough data collection and processing to achieve reliable results without the excessive computational burden of complete dataset analysis.

Inventive Principle:
Principle #16Partial or excessive action

3Area of stationary object

If all weather stations within a predefined area are processed, then the coverage of weather data improves, but the processing time increases due to evaluating multiple station combinations

Engineering Contradiction:
Improvecoverage of weather dataVSAvoidprocessing time
Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-selecting and organizing weather stations based on their spatial relationships to potential target locations before actual weather estimation is required. This preliminary organization of weather station subsets based on geographic criteria enables rapid retrieval and processing during actual weather reporting, maintaining comprehensive area coverage while minimizing real-time processing time.

Inventive Principle:
Principle #10Preliminary action
