Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-mutant controls are used to analyze different biomarkers, then the analysis coverage is improved, but the device complexity and preparation complexity increase
Solution Approach 1:
The patent combines multiple genotype-specific nucleic acid sequences into a single multiplexed reference material. Instead of using separate single-mutant controls for each biomarker, the invention integrates multiple genotype sequences (e.g., WT, Mutant 1, Mutant 2, etc.) into one unified reference material that can simultaneously control analysis for multiple biomarkers and genotypes.
Solution Approach 2:
The multiplexed reference material serves multiple functions simultaneously: it acts as a control for wild-type detection, multiple mutant detections, and quantitative analysis across different genotypes. This universal reference material replaces the need for multiple specialized single-mutant controls, enabling one reference material to handle diverse analysis requirements.
2Reliability
If multiple single-mutant controls are prepared, then each biomarker can be controlled, but the preparation time and cost increase
Solution Approach 1:
The patent merges the preparation process into a single transfection step where multiple genotype sequences are introduced simultaneously into cells. This consolidated approach replaces multiple separate preparation steps required for individual single-mutant controls, reducing both time and cost while maintaining comprehensive process control.
Solution Approach 2:
The reference material is prepared in advance as a complete multiplexed control containing all necessary genotype sequences. This preliminary preparation of a comprehensive reference material eliminates the need for sequential preparation of multiple single-mutant controls during the analysis workflow, streamlining the overall process.
3Adaptability or versatility
If a library of controls is used to analyze samples with unknown features, then the analysis capability is improved, but the quantity of reference materials required increases
Solution Approach 1:
The multiplexed reference material functions as a universal control that encompasses multiple genotypes within a single material. This universal approach allows analysis of samples with unknown features without requiring separate reference materials for each possible genotype, reducing the total quantity of reference materials needed while maintaining comprehensive analysis capability.
Solution Approach 2:
The patent combines multiple genotype-specific reference materials into a single multiplexed reference material. This consolidation reduces the number of separate reference materials required in the laboratory while preserving the ability to detect and control for multiple different genotypes and biomarkers.
