Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional storage and processing methods are used for whole genome sequencing data, then data can be stored and analyzed, but the cost of storage will soon outstrip the cost of sequencing the genome and processing time is excessive
Solution Approach 1:
The patent segments the genome assembly process into distinct functional modules including k-mer counting, de Bruijn graph construction, contig generation, and scaffolding. Each module can be independently optimized and processed in parallel, dramatically reducing overall processing time while maintaining assembly quality
Solution Approach 2:
The patent transitions from traditional linear sequence assembly to a graph-based dimensional representation using de Bruijn graphs. This dimensional change allows simultaneous processing of multiple sequence paths and enables efficient handling of repetitive regions through graph traversal algorithms
2Productivity
If more computing resources are allocated to process the data faster, then processing speed increases, but the memory, power, and time requirements for processing and analyzing the data increase
Solution Approach 1:
The patent replaces traditional CPU-based alignment mechanisms with FPGA-based parallel processing architecture. This substitution leverages hardware-level parallelism to achieve high-throughput alignment (200,000 alignments per second) while reducing per-operation power consumption through efficient resource utilization
Solution Approach 2:
The patent implements dynamic parameter adjustment in the alignment algorithm, including adaptive k-mer sizes, variable thread counts, and configurable accuracy thresholds. These parameter changes allow the system to optimize the balance between processing speed and resource consumption based on available computing power and time constraints
3Measurement precision
If comprehensive analysis is performed on the genetic sequence data, then accuracy of variant detection improves, but the time required to complete analysis with thirty times coverage increases
Solution Approach 1:
The patent performs preliminary filtering and preprocessing of sequence data before full analysis, including quality score filtering, duplicate removal, and initial alignment validation. This preliminary action reduces the data volume requiring comprehensive analysis while preserving all true variants, thereby maintaining accuracy while reducing time
Solution Approach 2:
The patent implements continuous processing pipelines where alignment, variant calling, and validation operations overlap in time through parallel execution. Multiple analysis tasks are performed concurrently on different data segments, ensuring continuous productive action without sacrificing comprehensiveness
