Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation mode is used for biological drug expression and purification, then flexibility and adaptability are maintained, but throughput is limited and productivity is low
Solution Approach 1:
The system enables self-service automation where robots perform liquid operations, sample transfers, and detection tasks without human intervention. The automated control system coordinates incubators, liquid operation stations, and detection platforms to autonomously complete the entire workflow from sample preparation to analysis, achieving throughput increases of orders of magnitude while eliminating manual bottlenecks
Solution Approach 2:
Manual mechanical operations are replaced with automated robotic systems. Robots equipped with liquid handling capabilities perform pipetting, mixing, and sample transfer tasks. The system substitutes human-operated mechanical processes with computer-controlled automated mechanisms, enabling high-throughput processing while maintaining operational precision and consistency
2Reliability
If large personnel teams are deployed for manual operations, then comprehensive detection can be performed, but human resource costs increase and process stability decreases
Solution Approach 1:
The automated system integrates multiple functions into unified platforms. Liquid operation stations perform mixing, pipetting, and sample preparation. Detection platforms simultaneously conduct multiple assays including protein concentration measurement, purity analysis, and characterization. This multi-functionality eliminates the need for specialized personnel for each task while ensuring consistent, reproducible results across all operations
Solution Approach 2:
The system incorporates automated control and monitoring with real-time feedback mechanisms. Sensors track environmental conditions in incubators, detect sample properties during processing, and provide data to the automated control system. This closed-loop feedback ensures process parameters remain within optimal ranges, maintaining high reliability and stability without requiring constant human supervision
3Object-affected harmful factors
If open laboratory environment is used for manual operations, then accessibility and ease of operation are improved, but sample contamination risk increases and biological safety is compromised
Solution Approach 1:
The system creates controlled, isolated environments for sample processing. Incubators maintain sterile conditions with controlled atmospheres. Liquid operation stations and detection platforms operate in enclosed spaces that prevent contamination from the external laboratory environment. This inert environment protection eliminates contamination risks while maintaining full operational capability through automated interfaces
Solution Approach 2:
The automated system acts as an intermediary between the external laboratory environment and sensitive samples. Robots and automated platforms handle all sample operations within controlled environments, serving as a buffer that prevents direct exposure to potential contaminants. This intermediary approach protects samples while allowing researchers to access and control the system through standardized interfaces
4Loss of information
If manual data collection and analysis is performed, then flexibility in data processing is maintained, but data completeness decreases and data loss occurs
Solution Approach 1:
The system implements continuous automated data collection throughout the entire workflow. Sensors continuously monitor environmental parameters in incubators. Detection platforms continuously acquire measurement data during assays. The automated control system continuously logs all operational parameters and results. This continuous data acquisition eliminates gaps and ensures complete, loss-free data records without requiring manual intervention
Solution Approach 2:
Manual data collection and processing are replaced with automated digital systems. The automated control system electronically captures all data from detectors and sensors, eliminating transcription errors and data loss. Automated analysis algorithms process the data consistently, replacing variable manual analysis. This digital substitution ensures complete, accurate data management while providing sophisticated analytical capabilities
