Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional heavy bases and foundations are used for cross-flow hydraulic turbomachines, then the structural stability is improved, but the complexity and cost of assembly and disassembly operations increase significantly
Solution Approach 1:
The turbomachine is divided into modular stages that can be assembled and disassembled independently. Each stage includes turbine components, generator, and associated equipment that can be handled as separate units, enabling step-by-step installation and maintenance operations from vessels.
Solution Approach 2:
Guide blocks with cable reels act as intermediary devices between the vessel and the turbomachine components. These guide blocks facilitate controlled lowering and positioning of heavy turbine stages using cable systems, simplifying the assembly process from standard vessels.
2Manufacturing precision
If dedicated vessels with specialized equipment are used for assembly and disassembly, then the precision and control of installation operations are improved, but the operational costs and complexity increase
Solution Approach 1:
The guide blocks and cable reel systems are designed to be universal equipment that can be used with standard vessels for multiple operations including assembly, disassembly, and maintenance of different turbomachine components, eliminating the need for specialized dedicated vessels.
Solution Approach 2:
The cable reel systems on guide blocks automatically manage cable tension and payout during component lowering operations, providing self-regulating control that maintains installation precision without requiring complex external control systems on the vessel.
3Strength
If the entire turbomachine is assembled as a single unit, then the structural integrity is improved, but the ease of maintenance and repair is reduced
Solution Approach 1:
The turbomachine is constructed from multiple discrete stages that maintain structural integrity when assembled but can be independently removed for maintenance. Each stage includes complete functional units (turbine, generator, etc.) that can be serviced separately while the remaining structure stays intact.
Solution Approach 2:
Individual turbine stages and components can be extracted from the assembled structure for maintenance and repair operations. The modular design allows specific stages to be removed and replaced without dismantling the entire turbomachine, facilitating easier maintenance while preserving overall structural integrity.
