Innovation Solution

The development of the wheat variety W040650E1, which involves careful breeding and selection techniques, including cross-pollination methods, molecular marker-assisted selection, and backcrossing, to combine traits such as disease resistance, drought tolerance, and improved milling properties, resulting in a stable and homogeneous variety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to develop new wheat varieties, then genetic diversity and trait combination are improved, but the breeding time and process duration increase significantly

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Molecular marker-assisted selection provides continuous feedback on the genetic composition of breeding lines, allowing breeders to track the inheritance of desired traits through generations. This feedback mechanism enables informed selection decisions that accelerate the breeding process while maintaining genetic diversity and trait combination effectiveness.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional phenotypic selection (mechanical/physical observation of plant traits) with molecular marker-based genotypic selection. This substitution allows for early-stage selection of desired traits at the DNA level, dramatically reducing the time required to develop new varieties while maintaining the ability to combine multiple desirable traits.

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

2Adaptability or versatility

If multiple desirable traits are combined in wheat breeding, then variety improvement is achieved, but genetic stability and uniformity become difficult to ensure

Engineering Contradiction:
Improvedesirable traits combinationVSAvoidgenetic stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

Molecular markers provide real-time feedback on the genetic composition of breeding lines, allowing breeders to monitor and maintain genetic stability while combining multiple desirable traits. The feedback system enables precise tracking of allele inheritance and detection of genetic drift or unwanted variations throughout the breeding process.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses molecular markers as copies or proxies for the actual genes of interest. These marker copies allow breeders to select for multiple desirable traits simultaneously by tracking linked marker alleles, ensuring that the combination of traits is maintained with high genetic stability across generations without directly manipulating the target genes themselves.

Inventive Principle:
Principle #26Copying

3Productivity

If extensive breeding and selection processes are applied, then grain quality and yield potential are improved, but resource efficiency and manufacturing precision decrease

Engineering Contradiction:
Improvegrain yieldVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex, multi-generational phenotypic evaluation and selection processes with streamlined molecular marker-assisted selection. This substitution simplifies the breeding workflow by enabling early-generation selection based on DNA markers, reducing the number of field trials and selection cycles needed to achieve high grain yield and quality.

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

Solution Approach 2:

Molecular markers serve as simplified copies that represent complex genetic architectures underlying yield and quality traits. By selecting for marker alleles associated with desirable traits, breeders can achieve improved grain yield and quality without navigating the full complexity of traditional multi-trait selection processes across multiple generations.

Inventive Principle:
Principle #26Copying
