Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the traditional multi-step extraction method using disposable pipette, syringe, and filter is used, then pore water can be extracted from seabed sediment, but the process becomes complicated and time-consuming with increased risk of contamination
Solution Approach 1:
The patent combines multiple extraction tools (centrifugal separator tube, extractor with needle, filter, and pressing apparatus) into an integrated kit system. The centrifugal separator tube includes built-in components such as the elastic membrane at the bottom, filter at the side wall, and pressing apparatus on the cap, merging functions that previously required separate tools into a unified extraction system.
Solution Approach 2:
The extraction process is segmented into distinct functional components: the centrifugal separator tube for separation, the extractor with needle for extraction through the elastic membrane, the filter for purification, and the pressing apparatus for acceleration. Each component performs a specific function, allowing systematic organization and reducing operational complexity.
2Reliability
If the traditional multi-step extraction method is used, then pore water can be extracted, but the extraction time is extended causing delay in subsequent work
Solution Approach 1:
The kit is prepared in advance with all necessary components pre-assembled: the centrifugal separator tube with elastic membrane, filter, and pressing apparatus already in position. This preliminary preparation eliminates the need for sequential assembly of multiple tools during the extraction process, significantly reducing extraction time while maintaining reliability.
Solution Approach 2:
The pressing apparatus enables rapid acceleration of the extraction process by applying pressure to quickly force pore water through the elastic membrane and filter, skipping the slow natural filtration process and dramatically reducing the time required for complete extraction.
3Productivity
If the traditional multi-step extraction method using multiple tools is used, then pore water can be extracted, but the risk of sample contamination increases
Solution Approach 1:
The elastic membrane serves as an intermediary barrier between the pore water sample and the external environment during extraction. The filter acts as another intermediary layer that mediates the passage of pore water while blocking contaminants. These intermediary components protect the sample from contamination while enabling efficient extraction.
Solution Approach 2:
The kit uses disposable components such as the elastic membrane and filter that are discarded after a single use, eliminating cross-contamination risks between samples. Each extraction uses fresh disposable elements, ensuring sample purity while maintaining high extraction efficiency.
