Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cell-based biosensing systems are used for disease diagnosis, then detection capability is improved, but ethical, evolutionary, and industrial challenges arise from using genetically modified living organisms
Solution Approach 1:
The patent extracts the biosensing function from living cells by using cell-free biochemical systems. Specifically, it employs purified enzymes and molecular components in a controlled environment to perform detection algorithms, eliminating the need for genetically modified organisms while maintaining diagnostic capability. This extraction resolves the ethical and ecological concerns associated with living biosensors.
Solution Approach 2:
The patent replaces biological systems with biochemical systems. Instead of using living cells with genetic circuits, it substitutes purified molecular components (enzymes, nucleic acids, proteins) that can be precisely controlled and scaled. This substitution maintains the computational and sensing functions while eliminating the complexities and ethical issues of living organisms.
2Measurement precision
If cell-based biosensors are engineered with synthetic gene networks, then sensitivity and specificity are improved, but response time becomes slow due to intracellular diffusion and transcriptional processes
Solution Approach 1:
The patent extracts the biosensing and computation functions from slow cellular processes by using cell-free biochemical systems. Enzymatic reactions and molecular interactions occur directly in the assay environment without the delays of intracellular diffusion, transcription, and translation, achieving both high precision and rapid response.
Solution Approach 2:
The patent changes the fundamental parameters of the biosensing system by operating at the molecular level rather than cellular level. This allows reactions to proceed at diffusion-limited speeds rather than being constrained by cellular metabolism, dramatically improving response time while maintaining sensitivity through optimized molecular interactions.
3Adaptability or versatility
If non-orthogonal gene circuits are integrated into chassis cells, then functional capability is improved, but system robustness deteriorates due to unpredictable interactions with chassis components
Solution Approach 1:
The patent segments the biosensing system into independent, modular biochemical components that can be precisely characterized and controlled. Each enzyme and molecular component operates independently without interfering with cellular housekeeping functions, eliminating the unpredictable interactions that plague integrated gene circuits while maintaining full functional capability.
Solution Approach 2:
The patent replaces the complex, interactive biological system of gene circuits in living cells with a simplified biochemical system of purified components. This substitution eliminates the robustness issues arising from non-orthogonal gene-chassis interactions while preserving the ability to perform complex sensing and computation functions through carefully designed molecular networks.
4Extent of automation
If in vivo integration of algorithm using biological logic circuits is performed, then decision-making capability is improved, but manufacturing complexity increases due to lack of clear engineering principles
Solution Approach 1:
The patent performs all algorithm design, optimization, and testing in silico (on computers) before any physical implementation. Computational models are used to predict system behavior, optimize component parameters, and validate logic circuits beforehand, eliminating the need for iterative trial-and-error in the lab and dramatically simplifying manufacturing.
Solution Approach 2:
The patent uses computational copies of the biochemical systems to design and test algorithms before physical implementation. Virtual models of enzymes, metabolites, and reaction networks allow extensive optimization and testing without consuming physical materials, reducing manufacturing complexity by identifying and resolving issues in silico first.
