Engineering Contradiction Analysis
1Measurement precision
If traditional single-index evaluation methods (qPCR detection of single gene) are used, then the evaluation process is simple and fast, but the accuracy of determining cell identity and differentiation direction is insufficient
Solution Approach 1:
The patent segments the evaluation system into multiple independent modules: sample collection, RNA extraction, transcriptome sequencing, data processing, and machine learning prediction. Each module can be independently optimized and implemented, allowing the system to achieve high accuracy through multiple detection indices while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent transitions from single-gene detection (one-dimensional) to transcriptome-wide multi-gene detection (high-dimensional). By sequencing the entire transcriptome and analyzing expression patterns across hundreds of genes simultaneously, the system achieves comprehensive cell identity determination and differentiation direction assessment that was impossible with single-index methods.
2Measurement precision
If multiple genes are detected via qPCR to improve accuracy, then the accuracy of cell identity determination improves, but the labor and time required increase significantly
Solution Approach 1:
The patent replaces the mechanical manual process of multiple qPCR assays with an automated transcriptome sequencing system. Instead of manually performing multiple separate qPCR experiments, the system uses high-throughput sequencing to simultaneously detect expression of hundreds of genes, dramatically reducing time and labor while maintaining or improving accuracy.
Solution Approach 2:
The patent changes the detection parameter from single-gene expression levels to comprehensive transcriptome expression profiles. By analyzing the entire transcriptome rather than individual genes, the system achieves more accurate cell identity determination and differentiation assessment in a single experiment, eliminating the need for multiple sequential qPCR assays.
3Quantity of substance
If evaluations are based on different indices from various laboratories, then more evaluation data can be collected, but the data heterogeneity makes comparison and standardization difficult
Solution Approach 1:
The patent establishes a universal evaluation framework that can accommodate data from multiple laboratories and sources. By using standardized transcriptome sequencing protocols and a unified machine learning prediction model, the system can process heterogeneous data from different sources and transform them into comparable standardized outputs, enabling large-scale data collection while maintaining consistency.
Solution Approach 2:
The patent introduces standardized data processing and machine learning prediction models as intermediary layers between raw laboratory data and final evaluation results. These intermediaries normalize and harmonize data from different sources, transforming heterogeneous laboratory measurements into standardized prediction outputs that can be reliably compared across studies and laboratories.
4Reliability
If traditional evaluation methods are used, then the current evaluation standards can be maintained, but the functional design and optimization of novel biomaterials lacks theoretical and data support
Solution Approach 1:
The patent implements a feedback loop where transcriptome sequencing data is input into machine learning prediction models to generate quantitative predictions of cell differentiation. These predictions provide theoretical support and data-driven insights that feed back into the design and optimization of novel biomaterials, enabling iterative improvement based on quantitative evidence rather than traditional empirical evaluation.
