Solution Overview

Problem

Existing Achillea cultivars lack a long blooming habit and color-fast red flowers, with variable plant habits and fading flower colors, which limits their durability and aesthetic appeal in landscaping.

Innovation Solution

The development of Achillea millefolium 'Strawberry Seduction' with sturdy stems, uniform red flowers that resist fading, and thick dark green foliage, achieved through a breeding program focusing on these traits and stabilized through asexual reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Achillea cultivars are selected for variable plant habits and flower colors, then genetic diversity is maintained, but plant habit uniformity and color consistency deteriorate

Engineering Contradiction:

Improvegenetic diversityVSAvoidplant habit uniformity

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent extracts and eliminates the variable traits from the parent strain Achillea 'Summer Pastels' through selective breeding, isolating only the desired uniform red flower color and sturdy stem characteristics in the new cultivar 'Strawberry Seduction', thereby achieving consistency while maintaining the breeding program's overall genetic diversity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The breeding program deliberately changes key parameters including flower color (to uniform red), stem strength (to sturdy), and internode length (to short), transforming the variable parent strain into a consistent cultivar with predetermined characteristics

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If Achillea cultivars are selected for short blooming period, then resource consumption is reduced, but aesthetic appeal and landscape value deteriorate

Engineering Contradiction:

Improveresource consumptionVSAvoidblooming period

Core Design Contradiction:

Loss of energyVSDuration of action of moving object

Solution Approach 1:

The breeding program specifically targets and extends the blooming period parameter, achieving a five-week bloom duration that is significantly longer than typical Achillea cultivars, thereby enhancing landscape value while the cultivar maintains efficient resource utilization through its adapted growth habits

Inventive Principle:

Principle #35Parameter changes

3Quantity of substance

If Achillea cultivars are selected for thin stems and sparse foliage, then resource requirements are reduced, but structural stability and visual appeal deteriorate

Engineering Contradiction:

Improveresource requirementsVSAvoidstem sturdiness

Core Design Contradiction:

Quantity of substanceVSStrength

Solution Approach 1:

The breeding program fundamentally changes the stem and foliage parameters, producing cultivars with sturdy, thick stems and dense dark green foliage that provide both structural stability for supporting long blooming periods and enhanced visual appeal for landscape applications

Inventive Principle:

Principle #35Parameter changes

4Use of energy by moving object

If Achillea cultivars are selected for fading flower colors, then pigment production costs are reduced, but color-fastness and aesthetic durability deteriorate

Engineering Contradiction:

Improvepigment productionVSAvoidcolor-fastness

Core Design Contradiction:

Use of energy by moving objectVSDuration of action of stationary object

Solution Approach 1:

The breeding program specifically targets and enhances the color-fastness parameter, developing cultivars with vibrant red flowers that maintain their color intensity throughout the five-week blooming period, ensuring aesthetic durability in landscape settings

Inventive Principle:

Principle #35Parameter changes
