Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RNAi gene functional analysis is performed in heterogeneous cell populations, then comprehensive gene function coverage is achieved, but the ability to identify specific cellular phenotypes and their responsible effector constructs deteriorates
Solution Approach 1:
The patent segments the heterogeneous cell population analysis by introducing clonal barcodes that uniquely identify individual effector constructs. This allows the system to divide the complex heterogeneous response into traceable clonal components, enabling both comprehensive coverage and precise phenotype identification through barcode-linked tracking of specific effector constructs responsible for observed phenotypes
Solution Approach 2:
The patent introduces clonal barcodes as an intermediary element that mediates between the effector constructs and the phenotypic outcomes. These barcodes serve as traceable identifiers that link specific effector constructs to their functional effects, enabling precise identification of phenotype-responsible constructs while maintaining comprehensive gene function analysis in heterogeneous populations
2Ease of operation
If traditional functional genomic assays are used to study gene function, then the process is simple, but the ability to address complex cellular responses deteriorates
Solution Approach 1:
The patent creates a universal assay platform that combines the simplicity of traditional functional genomic assays with the capability to analyze complex cellular responses. The clonal barcode system serves as a multi-functional tool that enables both straightforward phenotypic screening and detailed clonal deconvolution, allowing the same assay to address both simple and complex gene function questions without requiring separate methodologies
3Measurement precision
If clonal barcodes are introduced in effector constructs, then the ability to determine clonal representation and identify specific effectors improves, but the device complexity increases
Solution Approach 1:
The patent uses clonal barcodes as informational copies that do not alter the functional properties of the effector constructs. These barcode sequences serve as redundant informational elements that can be read and analyzed without affecting the biological activity of the effector, thereby improving identification accuracy while adding minimal functional complexity to the system
