Innovation Solution

Development of a new soybean cultivar 29440802 with genetically engineered traits for herbicide resistance, disease tolerance, and modified fatty acid composition, achieved through methods like mutagenesis and transformation, combined with traditional breeding techniques to introduce desired characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional plant breeding methods are used to develop new soybean cultivars, then genetic stability and uniformity are maintained, but the development process is time-consuming and productivity is low

Engineering Contradiction:
Improvegenetic stabilityVSAvoidcultivar development speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent uses molecular markers to identify and select plants with desired traits before actual breeding occurs. This preliminary genetic screening allows breeders to focus resources on promising candidates, accelerating the breeding process while maintaining genetic stability through marker-assisted selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical phenotypic selection methods with molecular marker-based genetic analysis. This substitution enables faster, more accurate identification of desired traits at the DNA level, significantly reducing the time required for cultivar development while maintaining reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If transgenic methods are introduced to accelerate cultivar development, then productivity and trait integration improve, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvetrait integration speedVSAvoidtransgenic method complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses molecular markers as intermediary tools to bridge traditional breeding and transgenic approaches. These markers serve as detectable indicators that guide the integration of transgenic traits, simplifying the complex process by providing clear selection criteria and reducing the need for complex transgenic construction methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent develops a universal molecular marker system that can detect multiple desired traits simultaneously. This multi-functional approach allows the same marker system to screen for various characteristics (yield, disease resistance, quality traits) in a single process, reducing overall complexity while maintaining high productivity.

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

3Adaptability or versatility

If multiple desirable traits are combined in a single cultivar, then product quality and agronomic performance improve, but the breeding process becomes more complex and time-consuming

Engineering Contradiction:
Improvetrait combination diversityVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the complex task of combining multiple traits into manageable segments by developing specific molecular markers for each desired trait. This segmentation allows breeders to independently screen and select for individual traits, then combine them systematically, reducing overall process complexity while achieving diverse trait combinations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker analysis at multiple breeding stages. This continuous genetic monitoring provides real-time information about trait inheritance and combination success, allowing breeders to adjust selection strategies and efficiently combine multiple desirable traits without exponential complexity increase.

Inventive Principle:
Principle #23Feedback
