Solution Overview

Problem

The existing Hydrangea macrophylla cultivars have growth habits unsuitable for commercial production of ornamental potted plants, with inflorescences that are either too large or have non-uniform sepal pigmentation, and lack stability in asexual reproduction.

Innovation Solution

A new cultivar, Hydrangea macrophylla 'BCHY-11.026', resulting from a controlled cross between '8.1' and 'BC8.3', exhibits compact, attractive inflorescences with large sepalous florets that surround non-sepalous florets, stable asexual reproduction, and improved commercial characteristics, differing from similar varieties like 'BCHY-11.033' in inflorescence size and sepal pigmentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing Hydrangea macrophylla cultivars are used, then they have attractive inflorescences, but their growth habit is not suitable for commercial production of ornamental potted plants

Engineering Contradiction:

Improvesuitability for commercial productionVSAvoidgrowth habit

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The patent applies parameter changes by selecting and breeding plants with specific growth habit parameters (compact size, branching pattern, stem strength) that differ from traditional Hydrangea cultivars. The new cultivar exhibits altered growth parameters including compact habit, strong branching, and stem strength that enable commercial production while maintaining ornamental quality.

2Manufacturing precision

If existing Hydrangea macrophylla cultivars are used, then they produce inflorescences, but the sepal pigmentation is non-uniform and not commercially desirable

Engineering Contradiction:

Improveuniformity of sepal pigmentationVSAvoidsepal pigmentation pattern

Core Design Contradiction:

Manufacturing precisionVSShape

Solution Approach 1:

The patent applies parameter changes by selecting for specific pigmentation parameters including uniform color distribution, sepal shape, and color intensity. The new cultivar displays improved pigmentation uniformity and consistent sepal characteristics that meet commercial standards, representing a deliberate change in pigmentation parameters from traditional varieties.

3Reliability

If existing Hydrangea macrophylla cultivars are used, then they produce inflorescences, but they lack stability in asexual reproduction

Engineering Contradiction:

Improvestability in asexual reproductionVSAvoidgenetic stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent employs extensive asexual reproduction through cuttings to propagate the new cultivar, treating individual plant propagations as temporary means to establish stable genetic lines. Multiple generations of asexual reproduction have been performed to confirm genetic stability, using this iterative propagation process to validate reliability before commercial deployment.

AI summary

A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘BCHY-11.026’ originated as a controlled cross between varieties. The variety ‘BCHY-11.026’ has attractive inflorescences with relatively large sepalous florets, attractive, nonuniform sepal pigmentation and good commercial characteristics. Sepalous florets surround the non-sepalous florets in the center of the inforescence.
