Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the power supply module is integrated into the stern module, then the construction becomes more stable and vibrations are reduced, but heat dissipation becomes difficult
Solution Approach 1:
The power supply module is nested within the stern module, with the battery housing positioned inside the stern module's receiving space. This nesting arrangement maintains construction stability while allowing thermal management through strategically placed gaps between the battery housing and stern module walls that enable water flushing for heat dissipation.
Solution Approach 2:
Water acts as an intermediary cooling medium, directed through flushing channels formed by gaps between the battery housing and stern module. The water flows through these channels to carry away heat from the power supply module, solving the heat dissipation problem while maintaining the integrated stable construction.
2Ease of operation
If the connection mechanism is always accessible, then module replacement is easy, but unauthorized detachment during operation may occur
Solution Approach 1:
The power supply module is designed to be installed first, and only after its removal does the connection mechanism for the stern and bow modules become accessible. This preliminary arrangement ensures that during normal operation, the connection mechanism remains concealed and protected, preventing unauthorized detachment while allowing easy module replacement when needed.
Solution Approach 2:
The stern module is segmented into functional zones: the power supply module occupies the upper portion and conceals the connection mechanism, while the jet propulsion module is positioned below. This segmentation allows the connection mechanism to be protected during operation while remaining accessible for maintenance by removing the power supply module.
3Device complexity
If the watercraft is designed as a single integrated unit, then construction is simple, but variability and adaptability are limited
Solution Approach 1:
The watercraft is divided into detachable modules including the stern module with power supply and jet propulsion, and the bow module. These modules connect through a concealed connection mechanism, maintaining simple integrated construction during operation while allowing easy separation and reconfiguration for different watercraft configurations and applications.
Solution Approach 2:
The modular design with standardized connection mechanisms enables the same stern module with power supply and jet propulsion to be used with different bow modules to create various watercraft types. This universal approach provides high variability and adaptability while maintaining construction simplicity through repeated use of standard components.
