Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual gas collection and analysis operations are performed repeatedly on multiple secondary batteries, then individual analysis of each battery can be conducted, but analyst fatigue increases and human errors occur
Solution Approach 1:
The system enables automated self-service operation where the gas analysis apparatus automatically performs gas collection, delivery, and analysis without requiring continuous analyst intervention. The automated moving unit transports batteries between storage units and the gas diffusion chamber, and the system automatically delivers collected gas to the analysis unit, eliminating manual repetitive operations and their associated errors
Solution Approach 2:
Manual mechanical operations are replaced with an automated mechanical system. The battery moving unit with automated transport mechanisms substitutes for manual battery handling, and the automated gas delivery system replaces manual gas transfer operations, thereby improving both precision and reliability through consistent automated execution
2Measurement precision
If manual gas collection and analysis operations are performed repeatedly on multiple secondary batteries, then individual analysis of each battery can be conducted, but analysis time increases and efficiency decreases
Solution Approach 1:
The system implements continuous automated operation where multiple batteries can be analyzed in sequence without interruption. The automated moving unit continuously transports batteries between storage units and the gas diffusion chamber, and the gas delivery system continuously delivers collected gas to the analysis unit, maintaining uninterrupted analysis flow and significantly improving productivity while preserving analysis accuracy
Solution Approach 2:
Batteries are pre-positioned in the supply battery storage unit before analysis begins. The automated system retrieves batteries in advance and prepares them for analysis, eliminating wait time between samples. This preliminary preparation enables continuous workflow and improves overall analysis efficiency
3Reliability
If automated gas collection and analysis system is implemented, then human errors are minimized and operation consistency is improved, but device complexity increases
Solution Approach 1:
The automated moving unit serves multiple functions: it transports batteries from supply storage to the gas diffusion chamber, moves analyzed batteries to recovery storage, and coordinates with the gas delivery system. This multi-functionality reduces the need for separate dedicated components for each operation, thereby managing device complexity while maintaining high reliability
Solution Approach 2:
The gas diffusion chamber acts as an intermediary component that receives batteries, collects generated gas, and transfers gas to the analysis unit. This intermediary structure simplifies the overall system architecture by providing a centralized gas collection point, reducing the complexity of direct connections between multiple batteries and the analysis unit
