Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to prepare insoluble MIPs directly, then binding capacity and specificity can be achieved, but reproducibility is low and production is challenging
Solution Approach 1:
The patent divides the MIP preparation process into two separate stages: first preparing soluble MIPs with controlled molecular weights, then cross-linking them to form insoluble MIPs. This segmentation allows each stage to be optimized independently, improving reproducibility while maintaining ease of manufacture.
Solution Approach 2:
The patent performs preliminary preparation of soluble MIPs with desired binding properties before cross-linking. This preliminary action ensures that the MIPs have optimal molecular weights and binding capacities before being converted to insoluble form, thereby improving reproducibility of the final product.
2Productivity
If soluble MIPs are prepared and then cross-linked to form insoluble MIPs, then yield of high-affinity MIPs is enhanced, but additional processing steps are required
Solution Approach 1:
The patent controls the molecular weight of soluble MIPs by adjusting polymerization parameters, then uses cross-linking to transform them into insoluble MIPs. This parameter control approach maximizes the yield of high-affinity MIPs while the systematic process design keeps complexity manageable.
Solution Approach 2:
The patent uses soluble MIPs as an intermediary form between the polymerization reaction and the final insoluble MIP product. This intermediary state allows for better control over binding properties and facilitates purification before cross-linking, enhancing overall yield.
3Manufacturing precision
If MIPs are produced with consistent binding capacities, then quality is improved, but production cost may increase
Solution Approach 1:
The patent achieves consistent binding capacities by precisely controlling polymerization parameters such as monomer-to-template ratio, cross-linker concentration, and reaction conditions. This parameter control ensures uniform MIP properties across batches, and the method itself remains cost-effective compared to alternative purification approaches.
