Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new wheat varieties, then desirable traits can be combined, but the development process is time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify and select plants with desirable traits before completing the entire breeding cycle. This allows breeders to make informed selections early in the process, reducing the time needed to develop new varieties while maintaining the ability to combine multiple desirable traits.
Solution Approach 2:
The patent replaces traditional mechanical breeding methods with molecular marker-assisted selection. Instead of relying solely on phenotypic observation and manual selection, the system uses DNA-based markers to identify plants with desired traits, significantly accelerating the breeding process while improving precision.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then variety performance improves, but achieving uniformity and stability becomes difficult
Solution Approach 1:
The patent implements feedback mechanisms through molecular marker monitoring throughout the breeding process. By continuously checking the genetic composition of plants and comparing it against desired criteria, breeders can make real-time adjustments to ensure uniformity and stability are maintained while combining multiple desirable traits.
Solution Approach 2:
The patent utilizes parameter changes by monitoring and controlling specific genetic markers and phenotypic characteristics at different stages of the breeding process. This allows precise control over the genetic composition to ensure stability while achieving the desired combination of traits.
3Reliability
If genetic modifications are introduced to improve specific traits, then trait improvement is achieved, but the complexity of the variety increases
Solution Approach 1:
The patent applies the extraction principle by isolating and focusing on specific genetic markers and traits of interest rather than attempting to modify the entire genome. This allows targeted improvement of specific traits like disease resistance and stress tolerance while maintaining the overall simplicity and manageability of the variety.
Solution Approach 2:
The patent segments the genetic modification approach by introducing and managing individual genetic elements or markers separately rather than creating complex multi-gene modifications. This segmentation allows for easier control, monitoring, and stabilization of each trait contribution, reducing overall genetic complexity.
