Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then resistance to diseases and insects, resistance to heat and drought, reducing the time to crop maturity, greater yield, and better agronomic quality can be achieved, but mechanical harvesting requires uniformity of plant characteristics such as germination, stand establishment, growth rate, maturity, plant height and ear height which is difficult to maintain
Solution Approach 1:
The patent applies parameter changes by utilizing molecular markers with specific polymorphisms (SNPs, SSRs, AFLPs) to track and select for uniformity of plant characteristics. By changing the selection parameters from traditional phenotypic selection to molecular marker-based selection, the breeding process achieves better uniformity in germination, stand establishment, growth rate, maturity, plant height and ear height while managing the complexity through objective, measurable criteria.
Solution Approach 2:
The patent replaces the mechanical/phenotypic selection system with a molecular genetic system. Instead of relying on visual inspection and manual selection of uniform plants, the invention uses molecular markers and DNA analysis to identify and select plants with desired uniformity characteristics, thereby reducing the subjectivity and complexity of the breeding process while improving reliability.
2Productivity
If mechanical harvesting is implemented, then crop production efficiency is improved, but uniformity of plant characteristics including germination, stand establishment, growth rate, maturity, plant height and ear height becomes critical and difficult to achieve
Solution Approach 1:
The patent implements feedback mechanisms through molecular marker analysis and DNA profiling to continuously monitor and adjust the breeding process. By using feedback from molecular data, breeders can make real-time selections to ensure uniformity of plant characteristics is maintained, which is critical for mechanical harvesting efficiency while achieving the required precision in plant uniformity.
Solution Approach 2:
The invention substitutes phenotypic assessment with molecular genetic analysis to achieve precise control over plant uniformity. This replacement of mechanical/visual selection with molecular tools enables higher precision in achieving uniform germination, stand establishment, growth rate, maturity, plant height and ear height, directly supporting efficient mechanical harvesting.
3Reliability
If backcross conversion and transformation are used to introduce specific traits, then abiotic stress tolerance and disease resistance are improved, but the breeding process becomes more complex
Solution Approach 1:
The patent uses molecular markers as intermediaries to facilitate the backcross conversion and transformation process. These markers serve as mediators to track the introduction of specific traits for abiotic stress tolerance and disease resistance, simplifying the complex breeding process by providing objective, measurable criteria for selection and reducing the subjectivity and complexity involved in traditional breeding methods.
Solution Approach 2:
The invention replaces traditional phenotypic selection methods with molecular genetic tools to introduce and track specific traits. By using DNA markers and molecular analysis, the process of achieving abiotic stress tolerance and disease resistance becomes more precise and manageable, reducing the complexity that would otherwise arise from multi-generation selection and evaluation.
