Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing wheat varieties are used, then current agricultural practices can be maintained, but they lack comprehensive combination of desirable traits such as higher seed yield, disease resistance, drought tolerance, and heat tolerance

Engineering Contradiction:
Improveadaptability to environmental stressesVSAvoiddisease resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines multiple desirable traits from different parental germ plasm into a single wheat variety 6PDUA86B, including disease resistance, drought tolerance, heat tolerance, and improved agronomic characteristics. This merging of traits resolves the contradiction by creating a variety that simultaneously exhibits both adaptability to environmental stresses and reliability in disease resistance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wheat variety 6PDUA86B functions as a composite genetic material, integrating multiple gene pools and trait combinations from diverse parental lines. This composite approach allows the variety to possess a comprehensive set of desirable traits including resistance to multiple diseases, tolerance to various environmental stresses, and improved yield characteristics, thereby resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #40Composite materials

2Productivity

If multiple desirable traits are combined in a single variety, then adaptability and productivity improve, but the development process involves numerous steps with significant intervention

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs preliminary action by pre-selecting and characterizing parental lines with specific desirable traits before combining them. The breeding process systematically identifies and combines disease resistance, drought tolerance, heat tolerance, and agronomic characteristics in controlled steps, making the complex process more manageable and efficient while achieving high seed yield and comprehensive trait integration.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If genetic modifications are introduced for traits like herbicide resistance and altered nutritional quality, then trait versatility increases, but the variety requires locus conversion or single locus conversion

Engineering Contradiction:
Improvetrait versatilityVSAvoidbreeding operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by introducing specific locus conversions or single locus conversions into the wheat variety 6PDUA86B to confer particular traits such as herbicide resistance or altered nutritional quality. This approach allows targeted modification of specific genetic loci while maintaining the overall genetic background and desirable traits of the base variety, thereby increasing trait versatility while minimizing disruption to the breeding process.

Inventive Principle:
Principle #3Local quality
