Solution Overview

Problem

Existing Hydrangea varieties lack diverse flower colors and are susceptible to powdery mildew, a common fungal disease.

Innovation Solution

The development of Hydrangea macrophylla cultivar 'HYD CELEST' through asexual reproduction using semi-hardwood cuttings, which exhibits bi-colored petals and increased resistance to powdery mildew, achieved by cross-pollination between 'White' and 'Bogotana Blue' varieties, resulting in a unique flower pattern and enhanced disease resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional Hydrangea varieties are used, then single color flowers are produced, but flower color diversity is limited

Engineering Contradiction:

Improveflower color diversityVSAvoidcolor variation in petals

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by creating petals with non-uniform color distribution, specifically featuring blue spots or stripes on a white background. This localized color variation within individual petals achieves bi-colored appearance and increases flower color diversity while maintaining a coherent floral structure.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent creates composite color patterns in petals by combining different pigments (blue and white) within the same flower structure. The bi-colored petals result from composite genetic expression that produces multiple color zones, effectively creating a composite floral appearance that diversifies color presentation.

Inventive Principle:

Principle #40Composite materials

2Reliability

If conventional Hydrangea varieties are used, then standard disease resistance is provided, but resistance to powdery mildew is insufficient

Engineering Contradiction:

Improveresistance to powdery mildewVSAvoidsusceptibility to fungal disease

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies self-service by developing a Hydrangea variety that inherently possesses resistance to powdery mildew through its genetic composition. The plant serves its own protection needs without requiring external chemical treatments or additional protective measures, as the bi-colored phenotype is associated with enhanced natural resistance to fungal pathogens.

Inventive Principle:

Principle #25Self-service
