Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery passport information is transmitted using conventional communication methods, then information transmission can be achieved, but transmission efficiency and security are insufficient
Solution Approach 1:
The patent introduces an NFC module as an intermediary communication device between the battery management apparatus and external electronic devices. This mediator enables secure near-field communication while maintaining system efficiency, resolving the contradiction between transmission security and efficiency by providing a dedicated secure communication channel.
2Loss of information
If all battery passport information is transmitted to users, then complete information access is achieved, but information security and access control are compromised
Solution Approach 1:
The patent implements local quality by providing different levels of battery passport information access based on user authorization. Authorized users receive specific information subsets appropriate to their role, while maintaining overall information security. This resolves the contradiction by tailoring information access quality to specific user needs and security requirements.
Solution Approach 2:
The system changes the parameter of information access by implementing authorization levels that control what battery passport information is transmitted. Different authorization parameters enable or disable specific information types, allowing complete information accessibility for authorized users while maintaining security through parameter-based access control.
3Ease of operation
If battery management apparatus controls all communication, then centralized control is achieved, but system complexity and operational independence increase
Solution Approach 1:
The patent segments the communication function by separating the NFC communication capability from the battery management apparatus into an independent NFC module. This segmentation allows the main battery management system to remain simple while enabling direct communication operations without increasing overall system complexity, as the communication function is isolated in a dedicated module.
