Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If battery performance monitoring is implemented, then battery degradation can be diagnosed accurately, but system complexity and data management burden increase
Solution Approach 1:
A remote server acts as an intermediary between multiple electric vehicle control devices and the battery service providing system. The server collects operation information from multiple vehicles, manages the data centrally, and performs unified analysis to diagnose battery degradation. This mediator approach allows accurate monitoring without requiring complex local systems in each vehicle.
Solution Approach 2:
The remote server performs multiple functions: collecting operation information from various vehicles, storing data in databases, analyzing battery degradation patterns, and providing diagnostic results. This multi-functional approach consolidates complexity into a single system that serves multiple purposes, reducing overall system complexity while maintaining diagnostic accuracy.
2Productivity
If centralized data collection from multiple vehicles is implemented, then battery service optimization is improved, but data management complexity and communication overhead increase
Solution Approach 1:
The system continuously collects operation information from electric vehicles and maintains ongoing data accumulation in databases. This continuous data collection enables persistent optimization of battery services without requiring repeated full data transmissions, reducing communication overhead while maintaining service optimization efficiency.
Solution Approach 2:
The remote server creates and manages copies of operation information data in structured databases, allowing efficient storage, retrieval, and analysis of battery performance data. This data copying and centralized management approach enables rapid access to historical data for optimization decisions without requiring continuous real-time communication with all vehicles.
