Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If battery performance is tracked using conventional methods, then the system is simple to implement, but the measurement precision is insufficient due to lack of environmental context
Solution Approach 1:
The system segments battery performance monitoring into multiple independent components: location information acquisition module, environment information acquisition module, reference state information acquisition module, and performance detection module. Each module collects specific data types separately, which are then integrated to achieve comprehensive and accurate battery performance assessment while maintaining manageable system complexity through modular design
Solution Approach 2:
The patent introduces environment information (temperature, humidity) and location information as intermediary factors that mediate between the battery and the monitoring system. These intermediaries provide contextual data that enables more accurate performance detection without directly measuring battery state, thus improving measurement precision while keeping the system architecture organized and manageable
2Measurement precision
If environmental factors are considered in battery performance detection, then the measurement precision improves, but the loss of information increases due to multiple data sources
Solution Approach 1:
The system merges location information, environment information, and reference state information into a unified battery performance assessment. By combining these multiple data sources through a standardized data structure and processing framework, the system achieves comprehensive performance detection while preventing information loss through systematic integration rather than isolated processing
Solution Approach 2:
The patent transforms environmental parameters (temperature, humidity) and location data into meaningful performance indicators by comparing them against reference states. This parameter transformation converts raw environmental data into actionable performance metrics, maintaining measurement precision while reducing information management complexity through standardized parameter relationships
3Reliability
If reference cell data is collected from storage locations, then the reliability of performance detection improves, but the productivity decreases due to additional data collection requirements
Solution Approach 1:
The system performs preliminary data collection by acquiring reference state information from storage locations in advance, before actual battery performance monitoring begins. This preliminary action establishes a baseline database of environmental conditions and reference battery states, enabling more reliable real-time performance detection without requiring intensive data collection during operational monitoring, thus maintaining reliability while improving productivity
