Engineering Contradiction Analysis
1Productivity
If batteries are selected sequentially without comprehensive evaluation, then the selection process is simple and quick, but energy efficiency is poor and battery life is shortened
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring battery characteristic parameters (state of charge, health status, temperature) and using this information to dynamically adjust selection decisions. The control part receives real-time data from sensing parts and feeds it back into the scoring mechanism to optimize battery group selection, ensuring both efficiency and reliability.
Solution Approach 2:
The system changes parameters by evaluating multiple battery characteristic parameters simultaneously (state of charge, health status, temperature, capacity) rather than relying on single-parameter selection. This multi-parameter approach transforms the selection process from simple to comprehensive, improving both energy efficiency and battery life through scientifically grounded decision-making.
2Reliability
If multiple battery characteristics are comprehensively evaluated, then battery selection accuracy is improved, but the system complexity increases
Solution Approach 1:
The system segments the complex evaluation process into distinct functional modules: sensing parts for data collection, control part for processing and scoring, and execution part for battery group selection. This segmentation allows comprehensive multi-parameter evaluation while managing system complexity through modular architecture, where each module handles specific tasks independently.
Solution Approach 2:
The control part acts as an intermediary between the sensing parts (which collect battery data) and the execution parts (which perform battery exchange). It processes multiple battery characteristics, calculates scores, and determines optimal battery groups, thereby mediating the complex evaluation process and simplifying the overall system operation through centralized intelligent decision-making.
3Ease of operation
If batteries are not properly matched to vehicle requirements, then battery access is convenient, but energy efficiency deteriorates and battery life is reduced
Solution Approach 1:
The system performs preliminary actions by pre-evaluating and grouping batteries based on their characteristics before exchange operations. The control part calculates scores for different battery groups in advance, ensuring that when a battery exchange is requested, the system can quickly provide the optimal matched battery group without compromising energy efficiency or battery life during the actual exchange process.
