Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a traditional SQL database is used for train simulation data storage, then data storage capability is provided, but data reading speed is slow and real-time requirements cannot be met
Solution Approach 1:
The patent changes the storage medium parameter from traditional SQL database (disk-based) to Redis memory database (memory-based), transforming the data storage architecture to achieve both high-speed data reading and real-time performance requirements simultaneously
2Adaptability or versatility
If a remote communication module or message queue product is deployed alongside a database, then message communication functions are provided, but the system becomes bloated and complex
Solution Approach 1:
The patent merges the database and message queue functions into a single Redis system, where Redis serves both as the data storage backend and as the message communication mechanism, eliminating the need for separate deployment of multiple components and simplifying the overall system architecture
Solution Approach 2:
The patent makes Redis a multi-functional component that simultaneously provides data storage, data retrieval, and message publishing/subscribing capabilities, allowing a single system to fulfill multiple roles that traditionally required separate specialized components
3Quantity of substance
If traditional SQL database is used for storing simulation data with many Boolean values, then data storage is provided, but extensive storage space is required leading to high laboratory setup costs
Solution Approach 1:
The patent changes the data storage parameter from disk-based SQL database to memory-based Redis, providing more efficient storage utilization that reduces the physical storage space requirements while maintaining the same data storage capacity for simulation data
