Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual single cell processing is performed, then flexibility and adaptability are maintained, but processing time increases and throughput decreases
Solution Approach 1:
The system performs self-service through automated pipetting, heating, cooling, and sample processing steps without requiring manual intervention. The automated liquid handling system delivers reagents and performs processing steps autonomously, enabling high-throughput single-cell analysis while maintaining protocol consistency and reducing user skill requirements.
2Productivity
If automated single cell processing is implemented, then throughput increases, but system complexity increases
Solution Approach 1:
The system is divided into modular functional components including an automated liquid handling system, temperature control subsystems, imaging systems, and data processing modules. Each module performs a specific function and can operate independently, making the overall complex system manageable and easier to maintain while achieving high-throughput processing.
Solution Approach 2:
The automated liquid handling system serves multiple functions including reagent dispensing, sample transfer, and protocol execution. The temperature control system manages both heating and cooling operations. This multi-functionality reduces the need for separate dedicated devices, thereby managing system complexity while maintaining high throughput capability.
3Ease of operation
If expert user intervention is required, then processing accuracy is maintained, but accessibility and ease of operation decrease
Solution Approach 1:
The system incorporates feedback mechanisms where the control system monitors and adjusts processing parameters in real-time. The automated liquid handling system tracks reagent volumes and flow rates, while temperature control systems continuously regulate conditions. This feedback ensures consistent processing accuracy without requiring expert user intervention, thereby improving both accessibility and reliability.
4Adaptability or versatility
If high-cost cutting edge instrument systems are used, then analysis capability is improved, but cost-effectiveness decreases and access is limited
Solution Approach 1:
The system merges multiple high-cost individual instruments into a single integrated platform that performs cell capture, lysis, reverse transcription, library preparation, and imaging in one unified system. This consolidation reduces overall system cost while maintaining cutting-edge analysis capability, making advanced cytometry tools more accessible and cost-effective.
