Solution Overview

Problem

There is a need for a new Hydrangea macrophylla cultivar with attractive flower colors and stronger plant characteristics that can resist breaking in production and post-harvest situations, while also being stable across varying environmental conditions.

Innovation Solution

The cultivar 'Sidaseli' is developed through a planned breeding program, featuring a flattened inflorescence, unique red/purple petal coloration with a white center, dark foliage, and strong plant structure, which is reproduced true to type through asexual vegetative cuttings, differing from its parents and commercial varieties like 'Twilight' in foliage color, branching, and flowering timing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a new Hydrangea macrophylla cultivar is developed with attractive flower colors, then the visual appeal is improved, but the plant strength and resistance to breaking may be compromised

Engineering Contradiction:

Improvevisual appealVSAvoidplant strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crossings between parent plants with different characteristics (9723 and 9654), selecting for the optimal combination of flower color intensity and plant structural strength in the resulting cultivar

Inventive Principle:

Principle #35Parameter changes

2Strength

If the plant is bred for stronger structure to resist breaking, then the plant strength is improved, but the flower color attraction may be reduced

Engineering Contradiction:

Improveplant strengthVSAvoidflower color attraction

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The breeding process involved changing multiple genetic parameters simultaneously through cross-breeding, selecting individuals that exhibited both the desired structural strength for commercial handling and the attractive flower coloration with red/purple petals and white centers

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The cultivar combines genetic traits from both parent plants (9723 and 9654) to create a composite phenotype that integrates strong plant structure with attractive flower colors, similar to how composite materials combine different properties

Inventive Principle:

Principle #40Composite materials

3Ease of manufacture

If the cultivar is selected for unique flower coloration, then the visual distinctiveness is improved, but the stability across environmental conditions may be compromised

Engineering Contradiction:

Improvevisual distinctivenessVSAvoidenvironmental stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent employs vegetative propagation through cuttings rather than seed propagation, creating genetically identical clones that ensure stable reproduction of the unique flower coloration and other cultivar characteristics across different environmental conditions and generations

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

Asexual reproduction by vegetative cuttings creates exact genetic copies of the selected plant, ensuring that the unique features (flattened inflorescence, red/purple petals with white center, dark foliage) are reproduced true to type through 6 successive generations

Inventive Principle:

Principle #26Copying
