Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If PCR testing is used to detect SARS-CoV-2 infection, then the presence or absence of infection can be determined, but the ability to predict subsequent worsening is lost

Engineering Contradiction:
Improveinfection detection accuracyVSAvoidpredictive information for worsening
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the diagnostic approach by using PCR to detect viral presence while simultaneously measuring COPB2 protein levels as a separate biomarker. This segmentation allows each test to serve its specific function: PCR for infection confirmation and COPB2 for prognosis prediction, thereby resolving the contradiction between accurate infection detection and predictive capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces COPB2 protein levels as an intermediary biomarker that bridges the gap between infection status and clinical outcome prediction. This intermediary provides additional information that neither PCR alone nor direct clinical observation can provide, enabling prediction of worsening while maintaining accurate infection detection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If existing antibodies are used for COPB2 detection, then general COPB2 detection is possible, but effective diagnostic detection for predicting severe COVID-19 is not achieved

Engineering Contradiction:
ImproveCOPB2 detection capabilityVSAvoiddiagnostic reliability for severe COVID-19 prediction
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by designing antibodies with specific CDR sequences optimized for detecting the particular conformation or epitope of COPB2 that is relevant to severe COVID-19 pathology. This localized optimization of antibody structure at the CDR region ensures high reliability for diagnostic purposes while maintaining overall COPB2 detection capability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the parameters of the antibody molecules by specifying particular CDR amino acid sequences that optimize binding affinity and specificity for COPB2 in the context of severe COVID-19. This parameter optimization transforms general COPB2 detection into a reliable diagnostic tool for predicting severe outcomes.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If novel antibodies with specific CDR sequences are developed, then accurate COPB2 detection for predicting severe COVID-19 is achieved, but the complexity of antibody characterization and production increases

Solution Approach 1:

The patent applies preliminary action by pre-defining the optimal CDR sequences through prior research and characterization. This preliminary work establishes the precise antibody structure needed for accurate COPB2 detection, allowing for streamlined production and reduced complexity in subsequent manufacturing and quality control processes.
