Engineering Contradiction Analysis
1Duration of action of moving object
If conventional simulation tools are used to simulate intracellular responses, then short-term chemical reactions can be modeled, but the simulation cannot cover the entire life cycle of cells including protein production and degradation
Solution Approach 1:
The simulation system is divided into multiple functional modules: a database module for storing cell information, a model generation module for creating cell models, an expression module for protein quantification, and a simulation module for executing simulations. This segmentation allows each module to handle specific aspects of the cell life cycle, enabling comprehensive long-term simulation while maintaining manageable complexity.
Solution Approach 2:
The system performs preliminary actions by pre-processing gene expression data to generate protein quantification models before the actual simulation runs. The expression module constructs numerical models for protein production and degradation based on gene expression information, preparing all necessary parameters in advance so that the simulation module can execute long-term simulations efficiently without repeated calculations.
2Measurement precision
If existing simulation tools are used, then chemical reactions based on initial conditions can be simulated, but mass movement between cellular organelles and cytoplasm cannot be delicately analyzed
Solution Approach 1:
The simulation model incorporates local quality by treating different cellular regions (organelles and cytoplasm) as distinct spaces with unique properties. The 3D cell model includes specific spatial information for each organelle, allowing the system to simulate and analyze mass movement between different locations with different physical and chemical characteristics, thereby achieving precise measurement of transport dynamics.
Solution Approach 2:
The system transitions from conventional 1D or 2D reaction modeling to 3D spatial simulation. The simulation module executes simulations in a three-dimensional representation of the cell, enabling delicate analysis of mass movement between cellular organelles and cytoplasm by tracking particle trajectories and concentration gradients across multiple spatial dimensions.
3Productivity
If fragmentary simulation is executed, then specific chemical reactions can be modeled, but the production and degradation of proteins throughout cell life cycle cannot be simulated
Solution Approach 1:
The expression module incorporates feedback mechanisms by continuously monitoring and updating protein quantification based on gene expression data. The system uses feedback loops to adjust protein production and degradation rates dynamically, ensuring that the simulation accurately reflects the complex regulatory networks controlling protein levels throughout the cell life cycle, thereby maintaining high reliability while producing comprehensive results.
