Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex device construction is used to receive and release liquids in aircraft, then the device can handle various liquid quantities, but the filling speed and discharge capability are reduced
Solution Approach 1:
The device is divided into modular components: a tank module for liquid storage, a bulkhead module for flow control, and a filling module with a coiling hose pipe for liquid transfer. This segmentation allows each module to be optimized for its specific function while enabling flexible configuration for different liquid quantities without compromising filling speed or discharge capability.
2Device complexity
If atmospheric pressure alone is used for discharge, then the device structure can be simplified, but high velocity discharge is not achieved
Solution Approach 1:
The bulkhead module incorporates a pumping device that uses hydraulic principles to generate high velocity discharge. The pump creates pressure differential that forces liquid through the discharge aperture at high speed, overcoming the limitations of atmospheric pressure alone while maintaining a relatively simple device structure.
3Device complexity
If a single tank container is used, then the device structure is simplified, but the ability to react to existing liquid quantities is reduced
Solution Approach 1:
The bulkhead module includes a movable closing element that can dynamically adjust the opening size based on the quantity of liquid in the tank. This dynamic adjustment allows the device to adapt to different liquid quantities while maintaining a simple single-tank structure, enabling flexible response to varying operational requirements.
