Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a digital battery passport system is implemented to ensure data transparency, then data accessibility and transparency are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The system is divided into multiple independent modules: manufacturer module for data entry, distribution module for data dissemination, and verification module for data validation. Each module handles specific functions, reducing overall system complexity while maintaining data transparency across the battery lifecycle.
Solution Approach 2:
A blockchain-based intermediary layer is introduced to mediate between manufacturers and end users. This intermediary ensures transparent and tamper-proof data transmission without requiring direct complex interactions between all system participants, thus improving data accessibility while managing system complexity.
2Loss of information
If comprehensive battery data is collected and stored, then data completeness and sustainability tracking are improved, but data security and privacy protection challenges increase
Solution Approach 1:
The system creates cryptographic copies of battery data stored on the blockchain. These immutable copies ensure data completeness and sustainability tracking while the original sensitive data remains secured at the manufacturer level, reducing security risks associated with centralized data storage.
Solution Approach 2:
The blockchain provides an inert, tamper-proof environment for storing battery data. Once data is written to the blockchain, it cannot be altered or deleted, ensuring data integrity and security while maintaining complete transparency of battery lifecycle information.
3Object-affected harmful factors
If multiple access levels are implemented for different user groups, then data security and controlled accessibility are improved, but system operation complexity increases
Solution Approach 1:
Different access levels are assigned to different user groups based on their specific needs: manufacturers have full access to enter and modify data, distributors have read-only access to disseminate data, and end users have access to verify battery information. This localized access control improves security while maintaining operational simplicity for each user type.
4Reliability
If blockchain technology is integrated for secure data management, then data reliability and fraud detection are improved, but computational requirements and energy consumption increase
Solution Approach 1:
The system extracts only the essential battery data that requires immutable storage on the blockchain, while keeping detailed operational data at the manufacturer level. This selective approach maintains data reliability for critical information while minimizing the computational overhead and energy consumption associated with blockchain operations.
