Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for extraction and purification, then flexibility and adaptability are maintained, but labor intensity increases and processing time is excessive
Solution Approach 1:
The system performs automated liquid transfer, mixing, and magnetic bead manipulation through the mechanical arm and processing device, eliminating the need for manual intervention in repetitive tasks while maintaining process control
Solution Approach 2:
Manual mechanical operations are replaced with an automated mechanical arm system that can precisely position and manipulate samples, reagents, and magnetic beads through programmed movements along guide rails
2Reliability
If manual operations are performed, then process flexibility is maintained, but consistency and accuracy decrease due to individual variations
Solution Approach 1:
The mechanical arm system with guide rails replaces manual mechanical operations, providing consistent and repeatable movements for liquid transfer, sample positioning, and magnetic bead manipulation, eliminating human variability
Solution Approach 2:
The processing device integrates multiple functions including liquid transfer, mixing, magnetic attraction, and sample processing into a single automated system, ensuring consistent execution of all operations
3Productivity
If automated mechanical arm is used, then processing speed and throughput are improved, but device structure becomes more complex
Solution Approach 1:
The guide rail system is divided into multiple segments (first guide rail, second guide rail, third guide rail) that can move independently along different axes, allowing the mechanical arm to reach various positions through coordinated movement of discrete components
Solution Approach 2:
The mechanical arm operates in three-dimensional space by combining movements along horizontal guide rails with vertical movement of the processing device, enabling complex manipulation tasks through spatial coordination
