Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a digital battery passport system is implemented to ensure data transparency across all stages of the battery lifecycle, then data accessibility and transparency are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The system is divided into distinct modules: a manufacturer module for creating and managing digital battery passports, a distribution module for data exchange, and a user interface for accessing information. Each module has specific responsibilities, allowing the complex system to be managed through modular components rather than a monolithic structure.
Solution Approach 2:
The patent introduces intermediary components including a communication interface that mediates between manufacturers and the digital passport system, and a distribution module that acts as an intermediary for data exchange between different system components and external users, simplifying the overall system architecture.
2Loss of information
If comprehensive information about battery composition, sustainability, and performance is stored and made accessible, then information completeness is improved, but data management complexity increases
Solution Approach 1:
The digital battery passport is designed as a universal data structure that can store multiple types of information (composition, sustainability, performance, manufacturing details) in a standardized format. This multi-functional passport serves various purposes throughout the battery lifecycle without requiring separate systems for each data type.
Solution Approach 2:
The system allows for dynamic parameters including access levels for different user types, updateable sustainability scores, and modifiable information sets based on battery stage. This flexibility enables comprehensive information storage while managing complexity through parameter-based control rather than fixed structures.
3Reliability
If blockchain technology is used to secure and verify battery data, then data reliability and traceability are improved, but computational requirements and energy consumption increase
Solution Approach 1:
The system creates digital copies of battery information in the form of passports and blockchain records. Instead of physically tracking and verifying battery components, the system uses cryptographic copies of data that can be verified without energy-intensive physical processes, maintaining reliability while reducing energy consumption.
Solution Approach 2:
The patent replaces physical verification mechanisms with cryptographic and digital verification systems. Blockchain consensus mechanisms and digital signatures substitute for physical inspection and manual verification processes, reducing energy consumption while maintaining or improving data reliability.
4Ease of operation
If multiple access levels are implemented for different user types, then user-specific data control is improved, but system operation complexity increases
Solution Approach 1:
The system implements local quality control by providing different access levels and information visibility for different user types (manufacturers, regulators, consumers, recyclers). Each user category receives tailored information appropriate to their needs and responsibilities, simplifying their interaction while maintaining overall system control.
