Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to develop soybean varieties, then the breeding process can be completed using traditional techniques, but it becomes difficult to combine multiple desirable traits such as disease resistance, drought tolerance, and improved nutritional quality in a single variety

Engineering Contradiction:
Improveability to combine multiple desirable traitsVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple desirable traits from different parental germplasm sources into a single soybean variety through systematic breeding programs. This includes integrating disease resistance, drought tolerance, and improved nutritional quality traits that were previously difficult to combine using conventional methods alone.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs molecular markers as intermediaries to track and select for multiple desirable traits simultaneously during the breeding process. This marker-assisted selection approach facilitates the combination of complex traits by providing precise genetic information about the presence and combination of desired characteristics in breeding lines.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple traits are combined in a single soybean variety, then the variety becomes more versatile and resistant to various stresses, but the breeding process becomes more complex and time-consuming

Engineering Contradiction:
Improveresistance to diseases and environmental stressesVSAvoidbreeding program duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent conducts preliminary evaluation of parental germplasm for multiple desirable traits before initiating the breeding program. This pre-screening allows breeders to select parents that already possess combinations of desired traits, reducing the time required to develop new varieties with multiple stress resistances and improved nutritional quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional phenotypic selection methods with molecular marker-assisted selection to identify and track desirable traits during breeding. This substitution accelerates the breeding process by providing early genetic information about trait presence, eliminating the need for lengthy field testing and phenotypic evaluation for each generation.

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

3Productivity

If traditional breeding methods are used, then the process is simpler to implement, but the resulting varieties may not achieve high yield stability across different growing conditions

Engineering Contradiction:
Improvegrain production yieldVSAvoidbreeding method simplicity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent systematically evaluates and selects breeding lines based on multiple parameters including yield, disease resistance, drought tolerance, and nutritional quality across different environments. This multi-parameter selection approach ensures that the resulting varieties achieve high yield stability across diverse growing conditions while maintaining the desired complex of traits.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent develops soybean varieties that possess multiple functions simultaneously - high yield potential, disease resistance, drought tolerance, and improved nutritional quality. This multi-functional approach ensures that the varieties perform well across different growing conditions and management practices, making them universally adaptable to various agricultural systems.

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