Solution Overview

Problem

The development of new maize varieties is a time-consuming process that takes six to twelve years, and there is a continuous need for stable, high-yielding maize varieties with improved traits such as disease resistance, drought tolerance, and better agronomic characteristics.

Innovation Solution

A novel maize variety, PH41VW, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and improved agronomic characteristics, using genetic manipulation and transformation techniques, and can be used to produce hybrid seeds through crossing with other maize varieties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used to develop new varieties with improved traits, then disease resistance and yield stability are improved, but the development time becomes excessively long (6-12 years)

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing inbred lines with desirable traits (disease resistance, yield stability) before hybrid development. The inbred line PH41VW was developed through preliminary breeding and selection processes, establishing a foundation that accelerates subsequent hybrid variety development and reduces overall breeding time.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If extensive breeding and selection processes are conducted to achieve high yield and stability, then yield performance is improved, but the complexity of the breeding program increases

Engineering Contradiction:
ImproveyieldVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The breeding program is segmented into distinct components: development of specific inbred lines (like PH41VW with identified traits), systematic crossing programs, and structured evaluation protocols. This segmentation allows parallel development of multiple inbred lines with different traits, which can then be combined in hybrid development, reducing overall program complexity while maintaining high yield potential.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs parameter changes by systematically evaluating and selecting inbred lines based on specific measurable parameters (disease resistance levels, yield components, maturity characteristics). By defining clear selection criteria and thresholds, the breeding program manages complexity through standardized parameter-based decision-making rather than subjective assessment.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple desirable traits are combined in a single hybrid variety, then agronomic performance is improved, but the breeding process becomes more time-consuming

Engineering Contradiction:
Improveagronomic characteristicsVSAvoidbreeding process time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The inbred line PH41VW serves as a universal parent that can be crossed with multiple different inbred lines to create various hybrid combinations, all inheriting its desirable traits. This multi-functionality allows the same inbred line to contribute to multiple hybrid varieties simultaneously, accelerating the development of diverse hybrids with consistent agronomic performance without proportionally increasing breeding time.

Inventive Principle:
Principle #6Universality (Multi-functionality)
