Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If serial analysis of individual DNA samples is performed, then analysis accuracy is improved, but cost and time requirements increase significantly
Solution Approach 1:
The method segments the analysis process by creating pooled DNA samples from multiple individuals, where each pool is analyzed together rather than individually. This allows parallel processing of multiple samples through a single sequencing run, maintaining analytical accuracy while dramatically improving throughput and reducing costs.
Solution Approach 2:
The invention merges multiple individual DNA samples into pooled samples that can be analyzed simultaneously. By combining samples from multiple individuals into pools and using pool-specific barcodes, the method enables concurrent analysis of multiple individuals in a single sequencing experiment, resolving the contradiction between accuracy and productivity.
2Manufacturing precision
If oligonucleotide libraries are generated using conventional methods, then probe quality is maintained, but generation cost and time increase
Solution Approach 1:
The method employs preliminary action by pre-synthesizing oligonucleotide probes with universal adapter sequences and restriction sites before the actual sequencing experiment. These pre-prepared probes are then amplified and pooled, allowing rapid generation of high-quality probe libraries without time-consuming conventional synthesis methods for each individual sample.
Solution Approach 2:
The invention uses copying by amplifying a small set of universal probe sequences through PCR to generate large populations of identical probes. This exponential amplification allows conversion of a small initial probe set into sufficient quantities for high-throughput sequencing, dramatically reducing generation time while maintaining probe quality through controlled amplification.
3Productivity
If high-throughput sequencing is implemented, then productivity is improved, but the complexity of sample processing increases
Solution Approach 1:
The method applies universality by designing a single universal probe sequence with universal adapter sequences that can bind to multiple different DNA samples. This universal probe design simplifies processing complexity while enabling high-throughput sequencing of diverse samples, as the same probe protocol works across all pool types without requiring sample-specific probe synthesis.
Solution Approach 2:
The invention introduces intermediary elements in the form of universal adapter sequences and restriction sites that mediate between the sequencing platform and diverse DNA samples. These intermediaries standardize the interaction interface, allowing complex sample processing to be simplified through uniform binding and amplification protocols while maintaining high throughput capability.
