Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If charger locations are geotagged by network providers or installation records, then charging station data is available for users, but the location accuracy deteriorates due to wrong geotagging or installation location deviations
Solution Approach 1:
The system uses feedback from multiple sources including vehicle positioning systems, user reports, and charging session data to continuously verify and update charger locations. When discrepancies are detected between stored locations and actual positions, the system initiates correction procedures to improve location accuracy while maintaining data availability.
Solution Approach 2:
The system enables self-service location correction by automatically comparing charger locations against vehicle positioning data and user-reported locations. The system autonomously identifies discrepancies and updates location records without requiring manual intervention from network providers or installers, thereby improving accuracy while maintaining continuous data availability.
2Ease of manufacture
If charger locations are manually geotagged during installation or by network providers, then initial location data is established, but location errors occur due to slight installation location deviations or geotagging mistakes
Solution Approach 1:
The system performs preliminary location verification by comparing installer-reported locations with actual vehicle positioning data before the data is fully integrated into the network. This preliminary check catches location errors early in the deployment process, maintaining ease of installation while improving location accuracy through automated verification.
Solution Approach 2:
The system replaces manual location verification processes with automated electronic verification using vehicle positioning systems and digital data comparison. This substitution eliminates human error in location verification while maintaining the simplicity of the installation process, as the automated system handles the precision-critical verification tasks.
3Measurement precision
If vehicle positioning systems are used to determine charger locations, then location accuracy is improved, but additional processing and comparison operations are required
Solution Approach 1:
The system uses the vehicle positioning system for multiple purposes: primary navigation, charger location verification, and discrepancy detection. By making the positioning system multi-functional, the patent avoids adding dedicated verification hardware, thereby improving location accuracy without proportionally increasing system complexity.
Solution Approach 2:
The system merges the location verification function with the existing vehicle positioning and charging session management systems. By combining these functions into a unified data processing framework, the patent achieves improved location accuracy through comprehensive data comparison while minimizing additional system complexity through integration rather than addition.

AI summary
Systems and methods are provided to update a location stored at a server for an electric charger. A determination is made that an electric vehicle is being charged at an electric charger, and a location of the electric charger may be retrieved from a server storing a plurality of locations of electric chargers. A determination of a location of the electric charger may be made based on a positioning system of the electric vehicle. The location of the electric charger retrieved from the server may be compared to the location of the electric charger determined based on the positioning system of the electric vehicle. Based on the comparison, the location stored at the server for the electric charger, the location stored at a server for an electric charger may be updated.
