Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a centralized database system is used to store battery data, then data accessibility is improved, but data security and fraud prevention deteriorate
Solution Approach 1:
The system segments battery data into multiple components stored across different entities (manufacturers, distributors, end-users) rather than centralizing all data in one database. Each entity maintains control over their specific data segments, improving both accessibility and security through distributed storage architecture.
Solution Approach 2:
Blockchain technology serves as an intermediary layer between data storage and access points. It provides a decentralized ledger that enables secure data sharing without requiring a central authority, thus maintaining data accessibility while enhancing security through cryptographic verification and immutable recording.
2Loss of information
If comprehensive battery lifecycle data is collected and stored, then data transparency is improved, but system complexity and storage requirements worsen
Solution Approach 1:
Battery lifecycle data is segmented into distinct categories (manufacturing data, distribution data, usage data, recycling data) and assigned to different stakeholders. This segmentation reduces overall system complexity by allowing each entity to manage only their relevant data segments while maintaining comprehensive transparency through the distributed ledger.
Solution Approach 2:
The blockchain platform provides universal functionality that handles multiple data types and operations (storage, verification, sharing, tracking) through a single standardized protocol. This multi-functional approach reduces system complexity compared to implementing separate specialized systems for each data management task.
3Reliability
If blockchain technology is implemented for battery passport management, then data security and fraud detection are improved, but implementation cost and processing time worsen
Solution Approach 1:
Data is verified and validated at the point of entry into the blockchain network, performing fraud detection preliminarily before data is stored and shared. This preliminary verification reduces the need for repeated validation checks later in the data lifecycle, thereby reducing overall processing time while maintaining high security standards.
Solution Approach 2:
The blockchain system performs automatic verification and validation of battery passport data through smart contracts and cryptographic protocols without requiring manual intervention. This self-service capability reduces processing time by eliminating manual review steps while maintaining rigorous fraud detection capabilities.

AI summary
The invention relates to a distribution module for managing digital battery passports in a management system. The management system includes a plurality of manufacturer modules, each manufacturer module being connected to the distribution module via a manufacturer module communication link. The distribution module includes a user access submodule configured to receive a passport code sent by a user, to retrieve from the manufacturer database of one of the manufacturer modules, on the corresponding manufacturer module communication link, using the passport code, a subset of data of the digital battery passport related to the passport code that is received and to transmit the subset of data that is retrieved to the user.
