Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location devices often inaccurately calculate positions as they rely solely on one data channel, such as GPS or WiFi, and fail to seamlessly switch between different wireless data channels based on availability, limiting their effectiveness globally.
Innovation Solution
A geographic localization system that combines information from multiple wireless sources like WiFi, Bluetooth, GPS, and cellular networks, using algorithms to infer and resolve location coordinates by processing signal intensity, time differences, and other communication link parameters, along with environmental sensors and data from satellite networks, to provide accurate location determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single wireless data channel (GPS, WiFi, or Bluetooth) is used for location calculation, then the device structure remains simple, but the location accuracy deteriorates and global applicability is limited
Solution Approach 1:
The patent combines multiple wireless data channels (GPS, WiFi, Bluetooth) into a unified location calculation system. The system integrates satellite positioning data with wireless network data, processing information from multiple sources simultaneously to determine location coordinates, thereby improving accuracy while maintaining manageable system complexity through unified processing logic
Solution Approach 2:
The location system is designed to universally accept and process data from multiple wireless channels (GPS satellites, WiFi networks, Bluetooth devices). The system can adaptively select and combine different data sources based on availability, making the location functionality universally applicable across different environments and scenarios
2Reliability
If multiple wireless data channels are integrated for location calculation, then location accuracy improves, but the device complexity and data processing requirements increase
Solution Approach 1:
The system dynamically adjusts its operation by adaptively selecting and combining different wireless data channels based on real-time availability and signal quality. The processing logic dynamically weights and integrates data from GPS, WiFi, and Bluetooth sources, optimizing location calculation reliability while managing processing complexity through adaptive rather than static multi-channel integration
Solution Approach 2:
The patent introduces an intermediary processing layer that receives raw data from multiple wireless channels and transforms it into integrated location information. This intermediary processing module coordinates the fusion of satellite positioning data with wireless network data, managing the complexity of multi-source integration while ensuring reliable location output
