Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If human researchers conduct experiments manually, then experimental flexibility and adaptability are maintained, but reproducibility and consistency of results deteriorate due to human skill variability
Solution Approach 1:
The system enables self-service experimentation where the automated platform independently executes synthesis and analysis operations without requiring continuous human intervention. The system autonomously adjusts parameters based on analysis results, performs iterative optimization, and generates reports, allowing experiments to serve themselves while maintaining high reproducibility.
Solution Approach 2:
Manual mechanical operations by researchers are replaced with automated robotic systems. The patent employs automated liquid handling robots, precision motors for parameter control, and computer-controlled synthesis equipment to substitute human manual operations, thereby eliminating variability introduced by different researchers' skills and techniques.
2Reliability
If automation is increased to improve reproducibility, then human error is reduced, but system complexity increases
Solution Approach 1:
The complex automated system is divided into modular functional segments: synthesis module, analysis module, parameter optimization module, and reporting module. Each module operates independently with defined interfaces, allowing the system to achieve high consistency through standardized modular components while managing complexity through clear separation of functions.
Solution Approach 2:
The automated platform incorporates universal components that perform multiple functions. For example, the analysis module can execute various types of measurements (spectroscopy, chromatography, etc.), and the robotic system can handle different material types and synthesis methods, reducing overall system complexity through multi-functional equipment rather than dedicated devices for each operation.
3Manufacturing precision
If iterative optimization is performed to achieve target material properties, then manufacturing precision is improved, but time consumption increases
Solution Approach 1:
The system maintains continuous useful action through automated iterative optimization. Rather than stopping between synthesis and analysis steps, the system continuously cycles through synthesis-analyis-adjustment operations without idle time. The automated platform keeps operating throughout the optimization process, performing useful work continuously to achieve target properties while minimizing total time through uninterrupted operation.
Solution Approach 2:
The system performs preliminary actions by pre-programming optimization algorithms and analysis protocols before experiments begin. Parameter adjustment strategies, analysis methods, and optimization criteria are predetermined, allowing the system to execute iterative optimization efficiently without time-consuming decision-making during the process, thus achieving high precision while reducing overall experiment duration.

AI summary
Provided is a modular experiment automation system including a main computer, a material synthesis module, and a material analysis module. The main computer interacts with a material synthesis module and a material analysis module. Upon a start request, it provides synthesis instructions for a target material. Once synthesis is complete, it instructs the analysis module to analyze the material. Based on the analysis results, if the error exceeds a threshold, it generates a new synthesis condition and re-initiates synthesis.
