Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional soybean breeding methods are used, then variety development can be achieved, but the process is time-consuming and inefficient
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting germplasm with desirable traits before the breeding process begins, and planning multiple generations of selection and crossing in advance. This systematic preparation reduces the overall time required for variety development while maintaining breeding efficiency.
Solution Approach 2:
The breeding process is segmented into distinct phases: germplasm analysis and definition of problems, establishment of program goals, selection of germplasm with specific traits, combining desirable traits through controlled crossing, and final variety development. This segmentation allows for efficient resource allocation and directional stability throughout the 6-12 year development cycle.
2Reliability
If multiple desirable traits are combined in a single variety, then agronomic performance improves, but the complexity of breeding increases
Solution Approach 1:
The patent identifies and selects germplasm with specific desirable traits (disease resistance, yield potential, stress tolerance) before the breeding process begins. By pre-selecting materials with known characteristics, the breeding program can systematically combine these traits across multiple generations without becoming overwhelmed by complexity.
Solution Approach 2:
The breeding program incorporates feedback mechanisms through evaluation of germplasm performance under different conditions, selection of the best performing lines for subsequent crossing, and continuous monitoring of trait inheritance. This feedback loop ensures that complex multi-trait combinations achieve stable agronomic performance while managing breeding program complexity.
3Stability of the object's composition
If breeding programs last 6-12 years, then variety stability is achieved, but resource consumption increases
Solution Approach 1:
The 6-12 year breeding program is divided into segmented phases, each with specific objectives and resource requirements. By segmenting the process, resources can be allocated efficiently to critical stages such as germplasm selection, controlled crossing, and multi-environment testing, while reducing overall resource consumption through targeted investment in high-value activities.
Solution Approach 2:
The patent employs preliminary selection and evaluation of germplasm before the main breeding process begins. By pre-identifying and selecting the most promising materials with desirable traits, the program reduces the number of lines that require extensive multi-year evaluation, thereby achieving variety stability while reducing overall resource consumption.
