Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If performance diagnosis and operating guide technology are implemented for coal gasification plants, then operational efficiency and reliability are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The operating guide system is divided into multiple functional modules including a performance analyzer module that analyzes plant performance data, a fuel determiner module that determines gasification suitability, an operating condition deriver module that derives optimal operating conditions, and a guide generator module that generates operation guides. Each module performs a specific function and processes data independently, making the complex system manageable and maintainable while providing comprehensive performance diagnosis and operating guidance
Solution Approach 2:
The system introduces an intermediary processing layer between the raw plant data and the operator decisions. The performance analyzer, fuel determiner, and operating condition deriver act as intermediaries that process raw data, apply analysis algorithms, and transform it into actionable operating guides. This intermediary layer simplifies the complexity by handling the analytical processing automatically, reducing the burden on operators while improving reliability
2Productivity
If comprehensive performance analysis and operating guides are provided, then operational efficiency is improved, but information processing time and computational resources increase
Solution Approach 1:
The system performs preliminary analysis by pre-determining fuel gasification suitability and pre-deriving operating conditions before actual plant operation. The fuel determiner analyzes fuel properties and determines gasification suitability in advance, while the operating condition deriver calculates optimal temperature ranges and operating parameters beforehand. This preliminary action reduces real-time analysis requirements and enables faster decision-making during plant operation
Solution Approach 2:
The system implements feedback mechanisms where the performance analyzer continuously monitors plant performance and compares it with the derived operating conditions. The guide generator provides feedback-based operation guides that adjust to actual plant conditions. This feedback loop enables efficient real-time operation by building on pre-analyzed data rather than requiring complete real-time analysis, thus improving productivity while managing analysis time
