Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If secondary batteries are collected from vehicles for reuse as stationary storage batteries, then resource utilization is improved, but the degradation states vary significantly due to different operating conditions making selection and grouping complex
Solution Approach 1:
The patent segments the battery selection and grouping process into distinct functional modules: a diagnosis unit that assesses individual battery degradation states, a determination unit that evaluates suitability for stationary storage based on diagnosed data, and a grouping unit that assembles batteries into packages. This segmentation transforms the complex overall task into manageable, automated sub-tasks that can be processed systematically.
Solution Approach 2:
The control device acts as an intermediary between the collected secondary batteries and the stationary storage battery assembly process. It receives diagnosis data from individual batteries, determines suitability based on predetermined criteria, and facilitates the grouping process. This intermediary function automates the selection and grouping operations, reducing manual complexity while enabling efficient resource utilization.
2Measurement precision
If individual analysis of each secondary battery is performed to assess degradation state, then selection accuracy is improved, but the time and resources required for analysis increase
Solution Approach 1:
The diagnosis unit enables secondary batteries to self-assess their own degradation states through automated diagnosis based on usage history and performance data. Each battery's degradation state is determined independently without requiring manual intervention or complex external testing, thus achieving accurate assessment while minimizing time and resource requirements.
Solution Approach 2:
The system performs preliminary diagnosis and degradation state assessment of secondary batteries before they are assembled into stationary storage packages. By conducting this analysis in advance and determining suitability beforehand, the system avoids time-consuming on-site evaluation and ensures accurate selection without delaying the overall remanufacturing process.
3Productivity
If secondary batteries are grouped and assembled into stationary storage batteries, then productivity is improved, but ensuring consistent performance across different degradation states becomes difficult
Solution Approach 1:
The patent applies local quality by allowing different secondary batteries with varying degradation states to be assigned to different roles within the stationary storage battery package. Rather than requiring all batteries to have identical characteristics, the system determines suitability based on specific degradation criteria and assembles packages that accommodate the actual condition of each battery, ensuring reliable performance while maintaining productivity.
Solution Approach 2:
The determination unit evaluates whether secondary batteries meet predetermined degradation state criteria for stationary storage use. By establishing and applying specific parameter thresholds for degradation, the system objectively determines which batteries are suitable for assembly, ensuring that only batteries within acceptable performance parameters are grouped together, thus maintaining reliability while enabling efficient assembly operations.
