Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If booster pump selection is not matched, then selection process is simple, but flow of circulating cooling water decreases and back pressure increases
Solution Approach 1:
The system performs preliminary calculations of water resistance and preliminary selection of booster pumps before final deployment. By pre-calculating resistance values and pre-selecting candidate pumps based on technical parameters, the system ensures optimal pump selection that guarantees sufficient cooling water flow while reducing the complexity of on-site decision-making.
Solution Approach 2:
The patent replaces manual pump selection processes with an automated computer-based calculation and selection system. The system automatically calculates water resistance, compares pump performance parameters, and selects the most suitable booster pump, substituting complex manual mechanical selection procedures with an intelligent computational approach.
2Productivity
If improper pump is selected, then selection time is reduced, but steam turbine operation efficiency decreases
Solution Approach 1:
The system enables self-service selection of booster pumps by providing an automated calculation and selection tool that users can operate independently. The system automatically inputs technical parameters, calculates water resistance, evaluates pump performance, and outputs the most suitable pump model, allowing users to complete the selection process without extensive expert intervention while ensuring optimal steam turbine efficiency.
Solution Approach 2:
The system incorporates feedback mechanisms where calculation results and selection outcomes are used to refine future selections. By analyzing the performance data and operational requirements, the system learns from previous selections to improve accuracy and reduce selection time for subsequent pump selection tasks, ensuring consistent optimization of steam turbine efficiency.
3Measurement precision
If detailed calculation is performed, then pump selection accuracy is improved, but calculation complexity increases
Solution Approach 1:
The calculation system is segmented into distinct functional modules: water resistance calculation module, pump performance evaluation module, and selection optimization module. Each module handles a specific aspect of the selection process, performing detailed calculations in isolated segments rather than as a monolithic complex system. This modular approach maintains high calculation accuracy while managing system complexity through functional decomposition.
