Solution Overview

Problem

The development of new soybean varieties is a time-consuming and unpredictable process due to the complexity of combining desirable traits like seed yield, disease resistance, and environmental adaptability, making it challenging for breeders to consistently produce superior varieties using conventional breeding methods.

Innovation Solution

The introduction of the soybean variety 4959932, which can be crossed with itself or other plants to produce hybrid seeds and plants with specific traits such as herbicide resistance, disease resistance, and improved nutritional quality, using methods like backcrossing and genetic transformation to introduce desired genetic loci, allowing for the development of stable and high-yielding soybean varieties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to combine desirable traits, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
ImproveadaptabilityVSAvoidbreeding time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by utilizing molecular markers to directly identify and select plants with desired genetic traits, transforming the breeding process from phenotypic selection to genotypic selection. This changes the fundamental parameter of trait detection from observable characteristics to DNA-level identification, enabling precise and rapid selection of plants with specific adaptations without lengthy breeding cycles

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical and time-intensive process of manual breeding and phenotypic evaluation with molecular marker-assisted selection. Instead of physically crossing plants and observing traits over generations, the invention uses DNA markers to identify and track desired genetic loci, substituting biochemical analysis for traditional breeding mechanics and significantly reducing the time required to develop adapted varieties

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

2Reliability

If multiple traits are combined in a single variety, then overall plant performance is improved, but the complexity of inheritance makes selection difficult

Engineering Contradiction:
Improvetrait consistencyVSAvoidbreeding complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by breaking down the complex task of selecting for multiple traits into individual, manageable genetic loci. Each desired trait is associated with specific molecular markers that can be independently tracked and selected. This allows breeders to address each trait separately through marker-assisted selection rather than attempting to select for all traits simultaneously, reducing the perceived complexity while achieving reliable multi-trait combinations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces molecular markers as intermediaries between the desired traits and the selection process. These markers serve as detectable proxies for the actual genetic loci controlling multiple traits, allowing breeders to indirectly select for complex trait combinations through simple marker detection. This intermediary system simplifies the selection process while ensuring reliable inheritance of multiple desirable traits

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If superior plants are identified through observation, then genetic superiority can be selected, but true genotypic value is masked by environmental factors

Engineering Contradiction:
Improvegenetic evaluation accuracyVSAvoidenvironmental interference
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces phenotypic observation and environmental performance measurement with direct genotypic analysis using molecular markers. Instead of measuring plant traits that are influenced by environmental conditions, the invention directly detects the genetic sequence or marker presence associated with desired traits, eliminating environmental interference from the measurement process entirely

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

Solution Approach 2:

The patent uses molecular markers as intermediaries that directly link to the genotypic value of plants without being influenced by environmental factors. These markers serve as stable, heritable indicators of genetic superiority that can be detected regardless of growing conditions, allowing accurate identification of superior plants based on their genetic potential rather than environmentally-modified phenotypes

Inventive Principle:
Principle #24Intermediary (Mediator)
