Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current methods are used for treating diseases involving SDF-1, then no specific antagonist is available, but this results in lack of effective treatment options

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidavailability of specific antagonist
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent uses nucleic acid molecules as intermediary substances that specifically bind to SDF-1, acting as a mediator between the therapeutic goal and the target protein. These nucleic acid antagonists serve as the missing specific antagonist mentioned in the contradiction, providing both availability and effectiveness simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention changes the parameter of molecular interaction by introducing nucleic acid molecules with specific sequences that bind to SDF-1 with defined affinity constants. This parameter change enables specific antagonism where none existed before, resolving the contradiction between availability and effectiveness.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If no specific detection method for SDF-1 is available, then diagnostic capabilities are limited, but this results in inability to detect SDF-1-mediated diseases

Engineering Contradiction:
Improvedetection capabilityVSAvoiddiagnostic options
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The nucleic acid molecules serve as intermediary detection agents that specifically bind to SDF-1, enabling precise measurement and detection. This intermediary approach provides both the measurement precision and diagnostic versatility needed to overcome the stated contradiction.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If general chemokine research is conducted without specific SDF-1 antagonists, then broad understanding is achieved, but this results in lack of targeted therapeutic intervention

Engineering Contradiction:
Improverange of applicationVSAvoidspecificity of intervention
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the broad chemokine research field by introducing specific nucleic acid molecules targeted at SDF-1. This segmentation allows simultaneous maintenance of broad research scope and achievement of targeted intervention specificity, resolving the contradiction between range and specificity.

Inventive Principle:
Principle #1Segmentation
