Culture Medium Panel Configuration for Cell Suitability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing a culture medium dedicated to a specific cell is time-consuming and costly, and existing methods for selecting an appropriate culture medium through repeated experiments are limited and unreliable.
Innovation Solution
Configuring a 'culture medium panel' with a small number of culture media, where a culture experiment is performed once on the panel, and a culture medium with satisfactory results is selected, reducing the duration and cost of developing a dedicated culture medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a culture medium panel with a small number of culture media is configured, then the duration and cost of developing a dedicated culture medium are reduced, but the suitability for cells with various characteristics may be compromised
Solution Approach 1:
The patent applies preliminary action by pre-configuring a culture medium panel with a small number of carefully selected culture media before actual cell culture experiments. The panel is designed in advance based on analysis of cell characteristics and culture medium compositions, allowing researchers to quickly select an appropriate culture medium without time-consuming development processes. This preliminary configuration resolves the contradiction by providing ready-to-use options that maintain high suitability while reducing development time.
2Device complexity
If the size of the culture medium panel is reduced, then the cost and complexity of experiments are reduced, but the reliability of selecting an appropriate culture medium may be compromised
Solution Approach 1:
The patent applies parameter changes by transforming the culture medium selection problem into a parameter optimization problem. It analyzes cell characteristics (such as cell type, growth rate, metabolic properties) and culture medium compositions (such as nutrient concentrations, pH, additives) as parameters, then uses computational methods to identify the optimal subset of culture media that maximizes selection reliability. This approach resolves the contradiction by maintaining high reliability with a reduced panel size through scientific parameter analysis rather than exhaustive experimentation.
3Reliability
If conventional methods are used to configure a culture medium panel, then proven culture media can be selected based on experience, but the panel size cannot be large due to experimental constraints
Solution Approach 1:
The patent applies copying by creating a virtual model or database of cell characteristics and culture medium compositions that can be analyzed computationally. Instead of relying solely on physical experimentation with large numbers of culture media, the system creates a digital representation that allows virtual screening and prediction of suitable culture media. This copying approach resolves the contradiction by enabling the evaluation of many more culture medium options than would be feasible through traditional experimentation, thereby expanding the effective panel size while maintaining reliability.
