Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery data exchange systems are static, prone to errors, cumbersome, and inefficient, making it difficult to share and manage data across the battery supply chain, which hinders efficient and reliable production.
Innovation Solution
A decentralized battery passport system that utilizes decentralized identifiers (DIDs) and associated data to facilitate secure, efficient, and customizable data sharing among supply chain participants, allowing for flexible access and control by data owners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If battery data is stored in a centralized database accessible via communication network, then data accessibility and information retrieval are improved, but data security and protection against unauthorized access deteriorate
Solution Approach 1:
The patent segments battery data into two categories: immutable data (stored securely in the battery management system and not accessible via communication network) and mutable data (stored in a table accessible to external systems). This segmentation allows public access to necessary operational data while protecting sensitive manufacturing and diagnostic information from unauthorized access.
Solution Approach 2:
The patent introduces a selective data transmission mechanism that acts as an intermediary between the battery management system and external systems. This intermediary selectively transmits only authorized data through the communication network, enabling information accessibility while maintaining security by filtering out sensitive data.
2Adaptability or versatility
If battery data is made publicly accessible through communication networks, then transparency and traceability are improved, but vulnerability to hacking and data protection deteriorate
Solution Approach 1:
The patent divides battery data into public and private segments. Public data (basic operational parameters) is made transparent and accessible for traceability purposes, while private data (manufacturing details, diagnostic information) remains protected. This segmentation achieves transparency where needed without exposing the system to hacking vulnerabilities.
Solution Approach 2:
The patent applies different accessibility qualities to different data elements within the battery passport. Each data element has its own access control characteristics, allowing high transparency for operational data while maintaining strong protection for sensitive data, thus achieving local quality differentiation in data accessibility.
3Loss of information
If all battery data is stored and made accessible, then complete traceability and information availability are improved, but data management complexity and storage requirements worsen
Solution Approach 1:
The patent segments the battery passport data structure into immutable and mutable sections, with further subdivision into public and private data categories. This hierarchical segmentation simplifies data management by organizing information according to accessibility and modification requirements, reducing the complexity of handling complete battery data sets.
Solution Approach 2:
The patent extracts and separates mutable data from the core immutable battery passport structure. By taking out frequently changing operational data into a separate accessible table, the system reduces the complexity of managing the core passport while maintaining complete information availability through controlled access to the extracted data.
