Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional soybean cultivars are used, then agricultural production continues with current methods, but significant yield losses occur due to pathogen susceptibility

Engineering Contradiction:

Improvedisease resistanceVSAvoidyield loss

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent introduces resistance genes (RG21 and RG22) into soybean cultivars in advance through genetic modification, creating pathogen-resistant varieties before field deployment. This preliminary genetic enhancement ensures that the crops possess inherent resistance mechanisms against Asian soybean rust and other pathogens, preventing yield losses before they occur

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent modifies the genetic parameters of soybean plants by introducing novel resistance genes with specific sequences (SEQ ID NO: 1 and SEQ ID NO: 12). These genetic parameter changes confer enhanced disease resistance, transforming susceptible cultivars into resistant ones that can maintain productivity despite pathogen pressure

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new resistance genes are introduced into soybean plants, then disease resistance is enhanced, but the complexity of plant development and breeding processes increases

Engineering Contradiction:

Improvepathogen resistanceVSAvoidbreeding process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and isolates specific resistance gene sequences (RG21 and RG22) from their original contexts, creating discrete, transferable genetic units. These extracted genes can be independently introduced into different soybean cultivars through genetic modification techniques, simplifying the breeding process compared to traditional methods that would require complex cross-breeding programs

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates copyable genetic templates of the resistance genes with defined sequences (SEQ ID NO: 1 and SEQ ID NO: 12). These standardized gene copies can be replicated and introduced into multiple cultivars using consistent protocols, reducing the complexity and variability inherent in traditional breeding approaches

Inventive Principle:

Principle #26Copying
