Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual methods are used for maintaining and differentiating human pluripotent stem cells, then flexibility and adaptability are maintained, but labor intensity increases and inter-technician variability is introduced
Solution Approach 1:
The automated liquid handling system performs cell culture operations autonomously without requiring continuous human intervention. The system self-manages medium dispensing, cell passaging, and differentiation processes, thereby eliminating inter-technician variability while maintaining process reliability through programmed protocols
Solution Approach 2:
Manual mechanical operations (pipetting, medium changes, cell handling) are replaced by an automated liquid handling system with robotic arms and programmable dispensers. This substitution eliminates human variability introduced during manual operations while maintaining the necessary flexibility through software-controlled protocols
2Productivity
If manual cell culture methods are used, then process flexibility is maintained, but sample size and throughput are limited
Solution Approach 1:
The automated system enables continuous cell culture operations without interruption by manually performing tasks. Multiple plates can be processed in sequence or parallel, with the system continuously dispensing medium, monitoring cells, and performing passaging operations, thereby increasing throughput and reducing total processing time
Solution Approach 2:
Culture protocols and differentiation procedures are pre-programmed into the automated system before experiments begin. This preliminary configuration allows the system to execute multiple samples simultaneously without requiring real-time human decision-making, thereby increasing sample size capacity and reducing overall processing time
3Manufacturing precision
If automated liquid handling is implemented, then precision and control are improved, but system complexity increases
Solution Approach 1:
The automated liquid handling system provides precise control over dispensing parameters (volume, speed, timing) through programmable parameters. By adjusting these parameters, the system achieves high precision in solution dispensing while managing system complexity through software-based parameter optimization rather than hardware complexity
