Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored on conventional battery analyzers, then battery analysis can be performed, but the data may be input wrongly or altered leading to erroneous calculations
Solution Approach 1:
The patent applies preliminary anti-action by pre-encrypting the battery data with encryption algorithms stored on the battery itself before the data leaves the battery. This preemptive security measure prevents unauthorized alteration or wrong input of data during transmission and analysis, as any modification would require the decryption key that only authorized analyzers possess. The encryption is established in advance to counteract potential data integrity threats.
Solution Approach 2:
The patent introduces encryption algorithms and decryption keys as intermediary elements between the battery data and the analyzer. These intermediaries act as mediators that protect the original data from direct exposure, ensuring that only properly authenticated analyzers can access and process the battery information. This intermediary layer prevents direct manipulation or corruption of the data.
2Ease of operation
If battery data is made accessible for analysis, then battery life estimation can be performed, but the data may be accessed in a manner detrimental to analysis or other functions
Solution Approach 1:
The patent applies local quality by implementing different encryption schemes for different portions of battery data. Critical data that requires high security is encrypted with more robust algorithms, while less sensitive information may use simpler encryption. This allows selective access where authorized analyzers can retrieve appropriate data based on their decryption capabilities, balancing accessibility with security according to the specific needs of each data element.
Solution Approach 2:
The patent utilizes parameter changes by employing multiple encryption algorithms with varying complexity and security levels. The system can dynamically select which encryption scheme to apply based on the data sensitivity and the authorized analyzer's capabilities. This allows the data accessibility and security parameters to be adjusted according to the specific analysis requirements while maintaining overall system security.
Data Source
AI summary
A storage battery comprises a data storage device that allows for storing and retrieving data that may be useful during the life of the battery. The device may include a radiofrequency tag applied to the surface of the battery. Data stored in the device may be accessed by various devices, such as battery analyzers that perform remaining life other analyses. Some or all of the data may be encrypted to require that approved or licensed devices only access and use the data. Some data may be encrypted in one manner, requiring a first key, and other data in a different manner, requiring a different key. The different data sets may have different purposes, such as for battery analysis (using no encryption or requiring the first key), and for warranty, manufacturing, retail tracking and other purposes (using the second key).
