Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding procedures are used to develop soybean varieties with desirable traits, then genetic diversity and adaptability are maintained, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvepredictability of breeding outcomesVSAvoidbreeding cycle duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by using pre-characterized parental lines with known genetic traits and markers before the actual breeding process. The parental lines are selected and prepared in advance with specific desirable traits (disease resistance, drought tolerance, high yield), allowing the breeding outcomes to be more predictable and reducing the overall time required by utilizing pre-optimized genetic material.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through the use of molecular markers and genomic selection. Genetic markers are used to track and select for desired traits during the breeding process, providing real-time information about the genetic composition of progeny. This feedback mechanism allows breeders to make informed decisions about which lines to advance, improving predictability and reducing time by eliminating unnecessary breeding cycles.

Inventive Principle:
Principle #23Feedback

2Reliability

If conventional breeding procedures are used to develop soybean varieties with desirable traits, then genetic diversity is maintained, but research costs increase significantly

Engineering Contradiction:
Improvestability of variety performanceVSAvoidresearch cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent replaces mechanical/conventional breeding methods with molecular and genomic techniques. Instead of relying solely on phenotypic selection and multiple generations of crossing, the patent uses molecular markers, DNA analysis, and genomic selection to identify and select for desirable traits. This substitution reduces the number of breeding cycles required, decreases field testing requirements, and ultimately lowers research costs while maintaining or improving variety stability.

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

Solution Approach 2:

The patent applies parameter changes by utilizing molecular and genetic parameters rather than solely phenotypic parameters. Genetic markers and DNA sequences are used as selectable parameters to identify lines with desired traits, allowing for more precise and efficient selection. This approach reduces the time and resources needed for traditional phenotypic evaluation and breeding cycles, thereby reducing overall research costs.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If genetic transformation and backcrossing are used to introduce specific traits, then breeding outcomes become more predictable and stable, but the complexity of the breeding program increases

Engineering Contradiction:
Improvestability of breeding outcomesVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct, manageable phases: parental line development, cross-generation breeding, molecular marker screening, and variety release. Each phase has specific objectives and criteria, making the overall complex process more organized and controllable. The use of molecular markers provides discrete, identifiable targets for selection, breaking down the complexity into actionable steps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses molecular markers as intermediaries between the desired traits and the breeding process. These markers serve as detectable proxies for the actual traits of interest, allowing breeders to select for traits indirectly through marker analysis. This intermediary approach simplifies the breeding program by providing objective, measurable criteria for selection without requiring direct observation of complex phenotypic traits.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If conventional breeding procedures are used, then agronomic traits can be improved, but the variability in genetic outcomes reduces consistency

Engineering Contradiction:
Improvegrain yieldVSAvoidgenetic consistency
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent changes the parameters used for selection from phenotypic to genotypic parameters. By using molecular markers and genomic data, the patent can select for specific genetic combinations that are known to produce consistent agronomic traits. This genetic parameter approach ensures more consistent outcomes because it directly targets the genetic basis of traits rather than relying on phenotypic expression, which can be influenced by environmental factors.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback through continuous genetic monitoring and molecular marker analysis throughout the breeding process. This feedback allows for real-time adjustment of breeding strategies to maintain genetic consistency. By monitoring the genetic composition of progeny and comparing it against desired criteria, the patent can ensure that only lines with consistent, desirable genetic outcomes are advanced, thereby improving both productivity and genetic stability.

Inventive Principle:
Principle #23Feedback
