Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional exhaust gas scrubber system is installed in an existing marine vessel, then emission reduction is achieved, but space consumption increases and transportation service is interrupted
Solution Approach 1:
The scrubber system is divided into separate functional modules: a scrubber vessel module for exhaust gas treatment and a scrubbing liquid processing module for liquid handling. This segmentation allows each module to be optimized independently and facilitates modular installation, reducing overall space requirements compared to integrated traditional systems.
Solution Approach 2:
The scrubber vessel module is positioned above the scrubbing liquid processing module, utilizing the vertical dimension to arrange components. This three-dimensional configuration reduces the horizontal footprint on the vessel deck, minimizing space consumption while maintaining all necessary functional capabilities.
2Object-affected harmful factors
If a traditional exhaust gas scrubber system is installed in an existing marine vessel, then emission reduction is achieved, but installation disruption increases
Solution Approach 1:
By dividing the system into independently installable modules, the installation process can be staged. The scrubbing liquid processing module can be installed first, followed by the scrubber vessel module, allowing for reduced installation disruption compared to installing a complete integrated system at once.
Solution Approach 2:
The modular design allows for preliminary preparation of modules before installation on the vessel. Connector parts and support frameworks can be pre-assembled, reducing on-site installation time and disruption to the vessel's transportation service.
3Area of stationary object
If a modularized scrubber system is used, then space consumption is minimized, but system complexity increases
Solution Approach 1:
The connector parts are designed with universal compatibility, allowing the same connector to interface between different modules and with the vessel's existing structures. This standardization simplifies the overall system by reducing the need for specialized custom connections, despite the modular architecture.
Solution Approach 2:
Standardized connector parts serve as intermediaries between the modular components and the vessel's existing infrastructure. These connectors simplify the integration process by providing a universal interface that reduces the complexity of connecting different modules and the vessel's existing systems.
4Object-affected harmful factors
If stricter environmental regulations are applied, then emission reduction is improved, but space requirements increase
Solution Approach 1:
The vertical arrangement of the scrubber vessel module above the liquid processing module utilizes the vertical dimension to accommodate the additional space requirements of enhanced emission control functionality. This allows stricter environmental regulations to be met without proportionally increasing the horizontal footprint on the vessel.
