Solution Overview

Problem

Current methods for evaluating the suitability of chondrocytes for transplantation are limited in statistical significance, as they primarily focus on selective gene analysis, which does not adequately assess the complex metabolic processes involved in tissue regeneration and implantation success.

Innovation Solution

An in vitro method that analyzes the transcriptome and gene expression of patient cells to create a comprehensive metabolic profile, allowing for a more accurate prediction of tissue regeneration and implantation success by comparing profiles indicative of successful or unsuccessful outcomes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If selective gene analysis is used to evaluate chondrocyte suitability for transplantation, then the evaluation process is simplified and can be performed more easily, but the statistical significance and accuracy of the prognosis is reduced

Engineering Contradiction:
Improveease of evaluationVSAvoidprognostic accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies universality by using a comprehensive transcriptome analysis approach that simultaneously evaluates all genes rather than selecting specific genes. This multi-functional method captures the complete metabolic profile of chondrocytes, enabling both simplified operation through standardized sequencing protocols and high prognostic accuracy through comprehensive data coverage of all gene expressions related to tissue regeneration and implantation success

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the parameter of gene analysis from selective (few genes) to comprehensive (all genes via transcriptome). By using next-generation sequencing to analyze the entire transcriptome, the method transforms the evaluation from a limited marker-based approach to a holistic gene expression profile analysis, thereby improving statistical significance while maintaining operational feasibility through automated bioinformatics pipelines

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If comprehensive transcriptome analysis of all genes is performed, then the statistical significance and prognostic accuracy is improved, but the complexity of the analysis method and data processing increases

Engineering Contradiction:
Improveprognostic accuracyVSAvoidanalysis complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the comprehensive transcriptome analysis into distinct processing stages: RNA extraction and sequencing, initial data processing and quality control, differential expression analysis, and clinical interpretation. This segmented approach manages the complexity of analyzing all genes by breaking it into manageable computational steps, each handled by specialized bioinformatics tools and algorithms

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses bioinformatics pipelines and computational algorithms as intermediaries between the raw transcriptome data and clinical interpretation. These intermediary computational tools automatically process the complex sequencing data, perform statistical analyses, and generate prognostic results, thereby reducing the perceived complexity for researchers and clinicians while maintaining high analytical accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If selective marker gene analysis is used, then the cost and time of analysis is reduced, but the ability to assess complex metabolic processes involved in tissue regeneration is insufficient

Engineering Contradiction:
Improveanalysis timeVSAvoidassessment reliability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The patent applies preliminary action by performing comprehensive transcriptome sequencing and processing in advance, generating complete gene expression profiles before clinical decision-making. This preliminary comprehensive analysis captures all metabolic processes related to tissue regeneration upfront, allowing for reliable prognostic assessment without requiring time-consuming follow-up analyses, as the complete gene expression data is already available for immediate interpretation

Inventive Principle:
Principle #10Preliminary action
