Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean variety development methods are used, then desirable traits can be combined in a single variety, but the process takes six to twelve years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by establishing a structured breeding program with predefined objectives and selecting germplasm with desired traits before the actual breeding process begins. This advance planning and preparation of materials with specific characteristics (higher seed yield, disease resistance, drought tolerance, etc.) allows the breeding process to proceed more efficiently toward the goal of combining multiple desirable traits in a single variety.
2Stability of the object's composition
If traditional soybean variety development methods are used, then stable high-yielding varieties can be developed, but the process is time-consuming and prone to directional changes
Solution Approach 1:
The patent implements feedback mechanisms through multi-environment testing and evaluation of breeding lines. The breeding program evaluates lines across different conditions and environments to assess stability of yield and traits. This feedback information is used to select the most stable and adaptable lines for advancement, ensuring that the final variety maintains consistent performance across diverse conditions while accelerating the selection process.
Solution Approach 2:
The patent applies parameter changes by evaluating breeding lines under multiple environmental conditions and measuring various parameters (yield, disease resistance, drought tolerance, maturity timing). By changing and measuring multiple parameters across different environments, the program identifies lines with stable performance and combines desirable trait combinations more efficiently than traditional single-environment selection.
3Adaptability or versatility
If multiple desirable traits are combined in a single variety, then agronomic performance improves, but the breeding process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases and objectives: (1) selection of germplasm with specific traits, (2) crossing and combination of desirable traits, (3) evaluation across multiple environments, and (4) selection of stable high-yielding lines. This segmentation of the breeding process into manageable stages with specific goals for each stage reduces overall complexity while systematically achieving multiple trait combinations.
