Solution Overview
Problem
Existing methods for determining load profiles of motor vehicles in a fleet face data protection issues due to the need for precise movement profiles, which are not effectively addressed by existing GPS-based systems.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS data is used to determine driving profiles, then measurement precision of vehicle usage is improved, but data protection issues arise due to creation of detailed movement profiles
Solution Approach 1:
The patent extracts only the necessary driving condition parameters (operating time, speed, acceleration) from the complete GPS data set, discarding location information. This extraction allows obtaining sufficient usage data while eliminating the harmful element that creates movement profiles and violates data protection.
Solution Approach 2:
The patent introduces an intermediary processing step that transforms raw GPS data into aggregated driving condition parameters. This intermediary layer processes the data to retain usage information while removing identifiable location data, thus mediating between measurement precision and data protection requirements.
2Object-affected harmful factors
If driving condition parameters are evaluated without location data, then data protection is improved, but information completeness about vehicle wear may deteriorate
Solution Approach 1:
The patent changes the parameters used for evaluation from location-based GPS coordinates to driving condition parameters (operating time, speed, acceleration). This parameter transformation maintains the ability to assess vehicle wear and usage while ensuring data protection compliance by eliminating location information.
Solution Approach 2:
The patent creates a simplified copy of the complete driving profile that captures essential usage characteristics through aggregated parameters rather than complete trajectory data. This copy retains sufficient information for wear assessment while being devoid of sensitive location details.
3Measurement precision
If statistical standard deviation of driving parameters is calculated, then measurement precision of wear assessment is improved, but data processing complexity increases
Solution Approach 1:
The patent replaces complex mechanical analysis of complete driving trajectories with statistical calculations on aggregated parameters. By substituting detailed spatial-temporal analysis with statistical standard deviation of driving conditions, the system achieves precise wear assessment with reduced computational complexity.
