Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are individually designed according to specific requirements, then the transformer meets specific performance requirements, but transportation and assembly become time-consuming and complex
Solution Approach 1:
The invention divides the transformer system into modular components (transformer unit, expansion vessel, cooling means) that can be independently manufactured and transported, then quickly assembled on-site. This segmentation allows each module to be optimized for its specific function while enabling rapid deployment through standardized connection interfaces.
Solution Approach 2:
The invention creates universal mounting structures and standardized connection interfaces that can accommodate different component configurations. The mounting structure serves multiple functions: structural support, alignment guidance, and integration with the transformer vessel, reducing the need for custom fabrication for each specific application.
2Adaptability or versatility
If components are individually designed with varying sizes and shapes, then specific functional requirements are met, but transportation becomes cumbersome
Solution Approach 1:
The invention transitions from custom-fit component designs to standardized dimensional specifications that conform to CSC container requirements. By establishing uniform size and shape parameters for mounting structures and components, the system enables efficient containerization and standardized transportation while maintaining functional adaptability through modular configuration.
3Reliability
If components are assembled on site with complex groundwork, then seismic requirements and stability are fulfilled, but assembly complexity and time increase
Solution Approach 1:
The invention incorporates seismic bracing and structural reinforcement into the mounting structure during manufacturing, before site installation. This preliminary integration of stability features eliminates the need for complex on-site groundwork and seismic arrangements, allowing straightforward assembly while maintaining high reliability and seismic resistance.
4Ease of manufacture
If cooling means and expansion vessel are transported separately, then transportation flexibility is improved, but assembly process becomes more complex
Solution Approach 1:
The invention introduces standardized fluidic connection interfaces and mounting structures as intermediaries between the transformer vessel, expansion vessel, and cooling means. These standardized interfaces simplify the assembly process by providing pre-configured connection points and alignment features, reducing the complexity of integrating separately transported components.
