Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pack-level monitoring is used, then system-level performance tracking is simplified, but individual cell-level issues and changes cannot be tracked
Solution Approach 1:
The patent divides the battery pack into individual monitorable units by placing a monitor at each cell level. Each monitor tracks voltage, temperature, and other parameters for its specific cell, enabling precise cell-level monitoring while maintaining manageable system complexity through modular architecture.
2Measurement precision
If individual cell monitoring is implemented, then cell-level performance data is captured, but system complexity and data management burden increase
Solution Approach 1:
The patent merges individual cell monitors into a coordinated system where multiple monitors communicate with a central controller. This consolidation allows precise cell-level tracking while managing data complexity through centralized processing and unified system architecture.
Solution Approach 2:
The monitor design incorporates multiple functions within each monitoring unit, including voltage sensing, temperature monitoring, communication capabilities, and data storage. This multi-functionality reduces the need for separate dedicated components for each measurement type, thereby managing overall system complexity.
3Loss of information
If battery life cycle data is collected, then recycling and refurbishment information is improved, but data loss occurs after first application
Solution Approach 1:
The patent implements preliminary data capture by equipping batteries with monitors that continuously track and store life cycle parameters from manufacturing through initial use. This preliminary action ensures comprehensive data collection before the battery reaches end-of-life, preventing information loss that would otherwise occur after first application.
Solution Approach 2:
The system establishes feedback loops where monitored data is continuously stored and made accessible for analysis. This feedback mechanism ensures that life cycle information is preserved and can be retrieved for recycling decisions, maintaining data integrity throughout the entire battery lifecycle.
