Solution Overview
Problem
Existing methods for determining user associations on mobile devices rely on manual selection, which limits the opportunity to provide enhanced functionality to associated users, and are inefficient in detecting colocation and movement patterns.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection of associations is used, then user control and accuracy of association are improved, but the opportunity to provide enhanced functionality to associated users is limited
Solution Approach 1:
The system automatically detects user associations by analyzing colocation patterns from GNSS position information without requiring manual user input. The devices self-determine associations based on geographic and temporal overlap, enabling the system to serve itself in identifying user relationships.
Solution Approach 2:
The patent replaces the mechanical manual selection process with an automated electronic system that uses GNSS position data, time stamps, and algorithmic comparison to detect colocation patterns and determine associations between devices.
2Adaptability or versatility
If automated detection of user associations is implemented, then opportunities for enhanced functionality are improved, but processing overhead increases
Solution Approach 1:
The patent extracts only the necessary position information and time stamps from GNSS data, comparing these specific parameters to determine colocation. By focusing on essential elements rather than processing all available device data, the system reduces processing overhead while maintaining detection capability.
Solution Approach 2:
The system performs partial comparison of position information by checking whether devices are collocated during overlapping time periods without analyzing every possible parameter. This selective approach provides sufficient functionality while minimizing processing requirements.
3Measurement precision
If comprehensive position information comparison is performed, then detection accuracy of colocation is improved, but processing time and computational resources increase
Solution Approach 1:
The system first checks whether time periods overlap before performing detailed position comparison. This preliminary filtering step avoids unnecessary computational analysis of non-overlapping periods, reducing processing time while maintaining accurate detection for relevant time windows.
Solution Approach 2:
The patent divides the analysis into discrete time periods with time stamps, comparing position information segment by segment rather than continuously. This segmentation allows the system to process data in manageable intervals, improving efficiency while maintaining detection accuracy for each segment.
