Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional one-by-one fabrication methods are used for 3DMM materials, then material optimization can be achieved through careful control, but productivity is extremely low with only several or tens of samples synthesized at a time
Solution Approach 1:
The invention segments the synthesis process into separate solution preparation stages (pore-forming template agent solutions and precursor solutions) that can be independently optimized and stored. This allows high-throughput parallel processing while maintaining precise control over each material's pore structure through dedicated solution formulations.
Solution Approach 2:
The invention performs preliminary actions by pre-preparing and storing pore-forming template agent solutions and precursor solutions before the actual synthesis. This pre-preparation enables rapid deployment during high-throughput experimentation without compromising the precision of pore structure control, as each solution is formulated in advance with specific compositions.
2Productivity
If direct-deposit methods are used for high-throughput synthesis, then productivity increases, but difficulty arises in preparing solutions with dissimilar condensation kinetics and chemistry
Solution Approach 1:
The invention uses an intermediary approach by developing standardized solution preparation protocols and container systems that mediate between different pore-forming template agent solutions and precursor solutions. This intermediary framework enables direct-deposit high-throughput methods by providing a common platform that handles the complexity of dissimilar condensation kinetics and chemistry.
Solution Approach 2:
The invention applies parameter changes by systematically varying solution composition parameters (concentrations, pH, additives) to optimize condensation kinetics for different material systems. This enables the direct-deposit method to handle diverse chemistry while maintaining high throughput, as each solution can be tuned with specific parameters.
3Productivity
If large-volume 3DMM material arrays are synthesized for high-throughput experimentation, then material discovery speed increases, but stability issues arise during redox reactions and template removal
Solution Approach 1:
The invention performs preliminary stabilization by preparing and storing pore-forming template agent solutions and precursor solutions under controlled conditions before synthesis. This pre-stabilization ensures that even when synthesizing large volumes of materials for high-throughput experimentation, the complexes remain stable during subsequent redox reactions and template removal processes.
Solution Approach 2:
The invention employs disposable stable containers for storing and handling pore-forming template agent solutions and precursor solutions. These containers provide stable, controlled environments that prevent degradation during storage and transport, ensuring reliability even when synthesizing large numbers of samples for rapid material discovery.
