Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sample collection and transfer methods are used, then the collection process is simple, but the exposure risk increases and excess specimen is collected
Solution Approach 1:
The patent combines the collection tube, transfer mechanism, and analysis device into an integrated closed system. The collection tube is directly coupled to the analysis device, eliminating the need for separate transfer steps using syringes or pipettes. This merging of functions reduces exposure risk while maintaining operational simplicity.
Solution Approach 2:
The patent introduces a controlled transfer mechanism as an intermediary between the collection tube and analysis device. This intermediary component enables precise dispensing of required specimen volumes while maintaining a closed system, thereby reducing exposure risk without significantly increasing complexity.
2Productivity
If conventional transfer methods with syringes or pipettes are used, then flexibility in transfer is maintained, but the number of workflow steps increases
Solution Approach 1:
The collection tube and analysis device are merged into a single integrated unit with direct fluid communication. This eliminates multiple intermediate transfer steps involving syringes or pipettes, thereby improving workflow efficiency without requiring complex transfer mechanisms.
Solution Approach 2:
The system is pre-configured with the collection tube already connected to the analysis device before specimen collection. This preliminary arrangement eliminates the need for post-collection assembly or multiple transfer operations, streamlining the workflow while keeping the device structure relatively simple.
3Quantity of substance
If a larger sample volume is collected, then sufficient specimen is available for analysis, but excess specimen is wasted
Solution Approach 1:
The system incorporates a controlled dispensing mechanism that provides feedback control during specimen transfer. This allows precise delivery of the exact volume required for analysis, preventing both insufficient and excessive specimen collection, thereby reducing waste while ensuring adequate sample availability.
Solution Approach 2:
The system enables precise control of specimen volume through adjustable dispensing parameters. By changing the dispensing volume parameter to match the exact analytical requirement, the system minimizes excess specimen collection and waste while ensuring sufficient sample for analysis.
