Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If battery performance monitoring is performed in a decentralized manner at each electric vehicle, then data collection complexity is reduced, but the efficiency of centralized performance evaluation and control logic optimization deteriorates
Solution Approach 1:
The patent merges data collection from multiple electric vehicles into a centralized server system. The server aggregates operation information, driving information, and environmental information from numerous vehicles to perform comprehensive battery performance evaluation, thereby improving evaluation efficiency while managing data collection complexity through systematic integration.
Solution Approach 2:
The centralized server performs multiple functions including data collection, battery performance evaluation, control logic optimization, and residual value determination. This multi-functional approach consolidates various monitoring and analysis tasks into a single system, improving overall productivity without proportionally increasing complexity.
2Measurement precision
If detailed operation and driving data are collected from all electric vehicles, then battery performance evaluation accuracy is improved, but data management complexity increases
Solution Approach 1:
The patent segments data management by categorizing information into operation information (battery voltage, current, temperature), driving information (speed, acceleration, route), and environmental information (temperature, humidity). This segmentation allows the system to collect detailed data for accurate evaluation while managing complexity through structured organization of different data types.
Solution Approach 2:
The centralized server acts as an intermediary between electric vehicles and the performance evaluation system. It receives, stores, and processes detailed data from multiple vehicles, then provides processed information for battery evaluation. This intermediary role enables accurate evaluation while simplifying the interface between vehicles and the analysis system.
3Duration of action of moving object
If charging/discharging control logic is updated frequently to optimize battery performance, then battery service life is extended, but system operation complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the centralized server continuously evaluates battery performance based on collected data, compares it with optimal performance criteria, and generates updated control logic when improvements are identified. This feedback-driven approach ensures control logic is updated only when necessary to extend battery life, avoiding unnecessary complexity from frequent updates.
Solution Approach 2:
The system performs preliminary evaluation of battery performance data before generating control logic updates. By pre-processing and analyzing data to identify performance degradation patterns before they become critical, the system can proactively optimize control logic, extending battery service life while managing update frequency to avoid excessive operational complexity.
4Measurement precision
If centralized battery performance monitoring is implemented across multiple electric vehicles, then residual value determination accuracy is improved, but infrastructure requirements increase
Solution Approach 1:
The patent merges residual value determination functionality into the existing centralized battery performance monitoring system. The same server that collects operation and driving data also performs residual value evaluation by analyzing battery performance trends, charging/discharging history, and degradation patterns. This merging approach improves residual value determination accuracy without requiring separate infrastructure.
Solution Approach 2:
The centralized server performs multiple functions including real-time performance monitoring, historical data analysis, control logic optimization, and residual value determination. This multi-functional infrastructure achieves accurate residual value assessment while avoiding the need for dedicated hardware or systems, thereby managing infrastructure requirements efficiently.
