Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery performance monitoring is performed manually or through distributed local systems, then maintenance can be performed, but the monitoring efficiency is low and battery lifespan is reduced due to uneven maintenance
Solution Approach 1:
The patent merges multiple distributed battery monitoring functions into a single centralized server system. The server collects operation information from multiple electric vehicles, aggregates big data, and performs unified battery performance diagnosis, replacing manual or locally-distributed monitoring approaches with an integrated centralized platform that improves both efficiency and reliability
Solution Approach 2:
The patent implements a feedback mechanism where the centralized server continuously collects battery operation data, analyzes performance degradation trends, and sends updated control logic back to the electric vehicles. This closed-loop feedback system enables dynamic optimization of charging/discharging strategies to extend battery lifespan while maintaining high monitoring efficiency
2Duration of action of stationary object
If charging/discharging control logic is updated frequently to optimize battery performance, then battery lifespan can be extended, but system complexity increases
Solution Approach 1:
The patent enables the battery system to self-optimize through automated control logic updates. The centralized server autonomously analyzes big data from multiple vehicles, determines optimal charging/discharging strategies, and automatically pushes updated control logic to affected vehicles without requiring manual intervention, thereby extending battery life while keeping system complexity manageable through automation
Solution Approach 2:
The patent optimizes battery performance by dynamically changing control parameters such as charging current limits, voltage thresholds, and temperature constraints based on real-time battery health assessment. The centralized server adjusts these parameters according to battery degradation patterns detected in the big data, extending service life through parameter optimization rather than hardware modifications
3Measurement precision
If centralized big data collection from multiple electric vehicles is implemented, then battery performance diagnosis accuracy is improved, but data transmission and processing requirements increase
Solution Approach 1:
The patent extracts only the essential battery operation parameters needed for performance diagnosis from the full set of vehicle data. The centralized server collects specific big data elements such as charging/discharging current, voltage, temperature, and state of charge information, filtering out unnecessary data to achieve accurate battery performance diagnosis while minimizing data transmission volume
