Solution Overview

Problem

Existing soybean cultivars lack improved combinations of desirable traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are essential for enhancing agricultural productivity and nutritional value.

Innovation Solution

Development of a new soybean cultivar (21360026) with specific genetic modifications and breeding techniques to introduce traits like herbicide resistance, disease resistance, and altered fatty acid composition, combined with advanced molecular biology methods for genetic transformation and introgression of transgenic traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional soybean breeding methods are used, then cultivar development can proceed with conventional traits, but the process takes 6-12 years and lacks improved combinations of desirable traits such as higher seed yield, disease resistance, and altered fatty acid profiles

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding cycle time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting parental lines with desirable traits (high seed yield, disease resistance, altered fatty acid profiles) and performing molecular marker analysis before crossing. This advance preparation and selection of genetically superior parents accelerates the breeding process while ensuring the desired productivity improvements are achieved in the developed cultivar.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If conventional breeding is used, then the breeding process is simpler, but it lacks precision in combining specific desirable traits from parental germplasm

Engineering Contradiction:
Improvetrait combination precisionVSAvoidbreeding process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements feedback through molecular marker analysis and genetic evaluation at multiple stages of the breeding process. By continuously monitoring and evaluating the genetic composition of breeding lines using molecular markers, the program can precisely track the inheritance of desirable traits and make informed decisions to achieve the desired trait combinations with high precision.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical/visual selection methods with molecular marker-based genetic analysis. Instead of relying on phenotypic observation alone, the breeding program uses DNA-level molecular markers to precisely identify and select for specific traits, thereby achieving superior manufacturing precision in trait combination despite increased process complexity.

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

3Reliability

If existing soybean cultivars are used, then no additional development resources are needed, but they lack resistance to diseases and insects, tolerance to drought and heat, and improved compositional traits

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct modular components: selection of parental lines with specific resistance traits, molecular marker analysis, controlled crossing, and evaluation of progeny. This segmented approach allows systematic incorporation of disease resistance and other desirable traits while managing breeding program complexity through structured, stepwise procedures.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If traditional breeding timelines are followed, then resource allocation can be predictable, but the development process cannot adapt quickly to changing agricultural needs or market demands

Engineering Contradiction:
Improvebreeding program adaptabilityVSAvoidtime to market
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamics by creating a flexible breeding program that can adapt its timeline and focus based on emerging agricultural needs and market demands. The use of molecular marker technology and accelerated generation techniques allows the program to dynamically adjust breeding priorities and speeds up development cycles, reducing time to market while maintaining the ability to respond to changing requirements.

Inventive Principle:
Principle #15Dynamics
