Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If photovoltaic power data is transmitted using traditional methods, then data transmission is simple and fast, but data security and integrity cannot be guaranteed
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between data acquisition and storage. The blockchain network acts as a trusted mediator that verifies and secures photovoltaic data through distributed consensus mechanisms, cryptographic hashing (SHA1 digest), and immutable ledger structures, thereby ensuring data integrity without requiring direct trust between system components
Solution Approach 2:
The patent segments the data transmission process into distinct stages: data acquisition, image conversion, processing, and blockchain storage. Each stage handles specific tasks independently, with the blockchain layer providing specialized security functions separate from the data collection and processing layers, allowing each component to be optimized independently
2Reliability
If photovoltaic data is converted into image data and processed, then data integrity is enhanced, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary conversion of photovoltaic data into image format before transmission and storage. This preliminary action allows the data to be processed and secured in a more robust format that resists tampering, while the image conversion itself is performed efficiently using standard image processing algorithms that balance quality and speed
