Solution Overview

Problem

Existing Astilbe cultivars lack compact, upright growth habits and vibrant, uniform flowering with cerise-colored flowers, which are desirable for attractive foliage and flower coloration in garden settings.

Innovation Solution

The development of the Astilbe arendsii×Astilbe japonica cultivar 'Verssilvery Pink' through controlled cross-pollination and asexual reproduction by divisions, resulting in a compact, upright plant with strong foliage and freely flowering habit, producing cerise-colored flowers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional Astilbe cultivars are used, then they have larger plant size, but they lack compactness and upright growth habit

Engineering Contradiction:

Improveplant habitVSAvoidplant height

Core Design Contradiction:

ShapeVSLength of moving object

Solution Approach 1:

The patent applies parameter changes by selectively breeding for specific growth parameters including compactness, upright habit, and reduced plant height. The cultivar 'Verssilvery Pink' was developed through controlled cross-pollination and selection to achieve a plant height of approximately 22.5 cm with a compact, upright form, representing a deliberate modification of growth parameters from traditional taller Astilbe varieties.

Principle #35Parameter changes

2Quantity of substance

If traditional Astilbe cultivars are used, then they have flowering capacity, but they lack uniform and dense flowering habit

Engineering Contradiction:

Improveflowering densityVSAvoidflowering uniformity

Core Design Contradiction:

Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by selecting for flowering parameters including flower density, uniformity, and color intensity. The cultivar 'Verssilvery Pink' exhibits enhanced flowering density with numerous flowers per inflorescence and uniform distribution throughout the plant, along with stable cerise-pink coloration, achieved through multi-generational selection and asexual reproduction by division.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs asexual reproduction by division to propagate the selected flowering traits. This method allows rapid multiplication of plants with desired flowering characteristics without the variability introduced by sexual reproduction, ensuring stable and uniform flowering performance across multiple generations.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Speed

If traditional Astilbe cultivars are used, then they have flower color, but they lack vibrant and dark cerise-colored flowers

Engineering Contradiction:

Improvecolor intensityVSAvoidcolor stability

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting for pigment intensity and color stability. The cultivar 'Verssilvery Pink' was bred to produce vibrant cerise-pink flowers with consistent coloration across different environmental conditions. The color parameters were optimized through selective breeding, resulting in reliable and intense flower color that maintains stability throughout the flowering season and across generations.
