Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If biochemical molecules are synthesized on a microarray substrate, then parallel synthesis efficiency is improved, but isolation and selective collection of individual molecules becomes difficult
Solution Approach 1:
The microarray substrate is divided into discrete spot units, each containing specific biochemical molecules. This segmentation allows individual spots to be selectively targeted and isolated using the extraction tool, enabling separate collection of different molecule types while maintaining the benefits of parallel synthesis across multiple spots.
Solution Approach 2:
An extraction tool is employed to selectively remove desired biochemical molecules from specific spots on the microarray substrate. This extraction process enables the isolation of individual molecules or clusters from the synthesized library, allowing selective collection and subsequent use of specific molecules without affecting others on the substrate.
2Ease of operation
If different kinds of biochemical molecules are handled in a batch, then processing simplicity is maintained, but application versatility is limited
Solution Approach 1:
The extraction tool selectively removes specific biochemical molecules from the microarray substrate based on their location information. This enables the isolation of individual molecule types from the synthesized library, allowing different molecules to be separately collected and applied to different applications, thereby extending versatility while maintaining operational simplicity through automated extraction.
Solution Approach 2:
Different biochemical molecules are synthesized at different locations (spots) on the microarray substrate. The extraction process targets specific locations based on location information, enabling selective isolation of molecules with specific properties. This local quality approach allows different molecules to be individually collected and applied to different uses, enhancing versatility.
3Measurement precision
If selective isolation of specific sequences is performed using PCR, then isolation precision is improved, but economic feasibility deteriorates
Solution Approach 1:
The extraction tool provides a direct physical extraction method that isolates specific biochemical molecules from the microarray substrate based on their location information. This approach achieves high isolation precision by targeting specific spots, while being more economically feasible than PCR amplification for all sequence types, as it applies universally to DNA, peptides, and proteins without requiring sequence-specific primers or amplification steps.
4Measurement precision
If DNA libraries are selectively amplified using specific primers, then isolation precision is improved, but applicability to other molecule types deteriorates
Solution Approach 1:
The extraction tool provides a universal isolation method that works for all types of biochemical molecules synthesized on the microarray substrate, including DNA, peptides, and proteins. Unlike PCR which is specific to DNA, this extraction approach uses location information to selectively remove desired molecules regardless of their type, thereby achieving both high isolation precision and broad applicability across different molecule types.
