Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If automated sample preparation system is implemented, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: liquid handling arm for sample transfer, plate handler for positioning, cooler block for temperature control, heater shaker unit for mixing, centrifuge for separation, and mass spectrometry subsystem for analysis. Each module performs a specific function, allowing the complex overall system to be managed through modular components that can be independently optimized and maintained.
Solution Approach 2:
The automated system performs sample preparation, processing, and analysis without requiring manual intervention. Scripts control the coordinated operation of multiple components, enabling the system to self-regulate and maintain consistent protocols. This automation eliminates human variability in sample handling while managing the complexity through programmed control sequences.
2Productivity
If high-throughput analysis is performed, then productivity is improved, but measurement precision may deteriorate
Solution Approach 1:
The system maintains continuous automated processing of multiple samples through coordinated operation of all subsystems. The liquid handling arm continuously transfers samples, the plate handler continuously positions plates, and the mass spectrometry subsystem continuously analyzes metabolites. This continuous automated operation ensures consistent precision across high throughput by eliminating interruptions and human variability.
Solution Approach 2:
The system incorporates quality control samples and calibration standards that provide feedback on measurement accuracy. The mass spectrometry subsystem receives feedback data that can be used to adjust analysis parameters, ensuring that high-throughput processing maintains the required precision and accuracy for clinical diagnostic applications.
3Reliability
If standardized protocols are enforced, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The system uses programmable control scripts that can be dynamically adjusted based on specific analytical requirements. While the hardware is configured for standardized protocols to ensure reliability, the software control layer allows adaptation to different metabolite panels, sample types, and diagnostic protocols. This dynamic control enables the system to maintain standardized execution of protocols while adapting to different clinical needs.
