Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sequential screening techniques are used for combinatorial libraries, then sample preparation and transfer can be performed, but the process becomes labor-intensive, time-consuming, and expensive
Solution Approach 1:
The patent segments the combinatorial library into numerous small individual samples (e.g., 96-well plates with multiple compounds per well) that can be processed in parallel. Each sample is contained in a separate container or well, allowing simultaneous handling and screening of multiple compounds without sequential processing, thereby reducing labor intensity and time consumption while maintaining ease of sample preparation and transfer.
2Quantity of substance
If large quantities of material are used for screening, then sufficient sample is available for analysis, but material waste increases
Solution Approach 1:
The patent extracts and isolates only the necessary amount of material for each screening operation from the combinatorial library. By using small individual samples (microliter volumes) in separate containers or wells, the system obtains sufficient material for analysis while minimizing the total quantity required, thereby reducing material waste while maintaining adequate sample availability for characterization.
Solution Approach 2:
The patent changes the scale parameter of sample quantity from large bulk amounts to small micro-volumes. By utilizing micro-scale sampling techniques and small container formats (e.g., 96-well plates), the system achieves adequate material availability for analysis while dramatically reducing the total material consumption and waste associated with traditional large-scale screening methods.
3Productivity
If only the most promising samples are reviewed, then resource allocation is optimized, but obscure variations that might lead to unexpected valuable compounds are ignored
Solution Approach 1:
The patent performs preliminary characterization of all samples in the combinatorial library using automated, high-throughput methods before selective in-depth analysis. This preliminary action provides initial data on all compounds, allowing resource allocation to be optimized for follow-up studies while ensuring that even obscure variations are initially characterized and not completely overlooked, thus balancing resource efficiency with comprehensive discovery potential.
