Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple desirable traits are combined into a single wheat variety through breeding, then the variety's overall performance and adaptability are improved, but the complexity of the breeding process and time required increase significantly

Engineering Contradiction:

Improvevariety adaptabilityVSAvoidbreeding process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The breeding process is divided into distinct stages: initial cross-breeding to combine traits from multiple parental varieties, followed by systematic selection and stabilization phases. This segmentation allows complex multi-trait combination to be managed through sequential, controlled steps rather than attempting all combinations simultaneously.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Parental varieties are pre-selected and characterized for specific desirable traits before crossing. This preliminary characterization ensures that the cross-breeding process targets specific trait combinations, reducing the complexity of managing unwanted variations and streamlining the subsequent selection process.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined into a single wheat variety through breeding, then the variety's overall performance and adaptability are improved, but the time required for development increases

Engineering Contradiction:

Improvevariety adaptabilityVSAvoidbreeding time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Systematic evaluation and selection processes provide continuous feedback on trait expression across generations. This feedback mechanism allows breeders to identify and retain desirable trait combinations efficiently, accelerating the stabilization process and reducing the time required to develop uniform, multi-trait varieties.

Inventive Principle:

Principle #23Feedback

3Productivity

If genetic transformation and genome editing are used to introduce specific traits, then breeding efficiency and precision are improved, but the complexity of the technical procedures increases

Engineering Contradiction:

Improvebreeding efficiencyVSAvoidprocedure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Molecular markers serve as intermediaries to track and select for desirable traits during breeding. These markers provide a reliable indicator system that simplifies the selection process, allowing breeders to identify plants with desired genetic modifications or trait combinations without complex phenotypic analysis, thus reducing procedural complexity while maintaining high efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If traditional cross-breeding methods are used to combine traits, then genetic diversity is improved, but the precision and uniformity of trait inheritance are reduced

Engineering Contradiction:

Improvegenetic diversityVSAvoidtrait inheritance uniformity

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Molecular marker-assisted selection replaces traditional, imprecise phenotypic selection methods. By using DNA-based markers to track trait inheritance, breeders achieve precise control over which traits are transmitted to subsequent generations, ensuring uniformity and predictability in trait inheritance while maintaining genetic diversity through controlled cross-breeding.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
