Solution Overview

Problem

Existing Hydrangea cultivars lack improved green-like flower colors and balanced characteristics such as compact growth and strong stems, with limited options for multi-colored flowers and disease resistance.

Innovation Solution

The development of a new Hydrangea cultivar 'Stramini' with greener colored flowers, strong stems, and multi-colored blooms, resulting from a breeding program combining Seedling 1012 and HY 2586, exhibiting traits distinct from 'Elbtal' and retaining characteristics through propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional Hydrangea cultivars are used, then traditional flower colors are maintained, but green-like flower colors are not achieved

Engineering Contradiction:

Improveflower colorVSAvoidcolor variety

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by modifying the chemical composition parameters of the flower pigments. Specifically, it alters the anthocyanin and delphinidin content ratios, as well as the pH sensitivity characteristics of the flowers, to achieve stable green-like colors that differ from traditional Hydrangea color ranges. This chemical parameter modification enables the novel green hue while maintaining the flower's structural integrity.

Inventive Principle:

Principle #35Parameter changes

2Strength

If existing Hydrangea varieties are used, then basic growth characteristics are maintained, but compact growth with strong stems is not achieved

Engineering Contradiction:

Improvestem strengthVSAvoidplant form

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The patent applies local quality by differentiating the characteristics of various plant parts. The stems exhibit enhanced mechanical strength and rigidity properties locally, while the overall plant maintains a compact mounded form. This localized optimization of stem strength independent of overall plant size allows the variety to achieve both compact growth habit and strong stem structure simultaneously.

Inventive Principle:

Principle #3Local quality

3Reliability

If conventional propagation methods are used, then reproduction is achieved, but disease resistance and trait consistency are not maintained

Engineering Contradiction:

Improvedisease resistanceVSAvoidtrait consistency

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies feedback mechanisms through systematic evaluation and selection during the breeding and propagation process. The variety demonstrates stable inheritance of desired traits including green flower color, compact growth, and disease resistance through controlled asexual propagation. The feedback loop of selecting propagules that maintain parental characteristics ensures both trait consistency and reliable disease resistance expression across generations.
