Solution Overview

Problem

Existing Helleborus cultivars lack uniformity and resistance to pests, with limited attractive flower coloration and shorter flowering periods.

Innovation Solution

A new cultivar, 'COSEH 710', resulting from a cross-pollination between unnamed proprietary seedlings of Helleborus niger and Helleborus lividus, exhibiting a unique combination of upright growth, dark green leaves, long flowering period, and large light green flowers with reddish-pink overtones, bred for increased vigor and uniformity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If existing Helleborus cultivars are used, then they can be grown in gardens, but they lack uniformity and have shorter flowering periods

Engineering Contradiction:

Improveflowering periodVSAvoiduniformity

Core Design Contradiction:

Duration of action of stationary objectVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in a prolonged flowering period (from December to March) and improved uniformity in flower color and size. The cross-breeding of Helleborus niger and Helleborus lividus creates a new cultivar with optimized genetic parameters for both flowering duration and uniformity.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If existing Helleborus cultivars are used, then they can be grown in gardens, but they have limited attractive flower coloration

Engineering Contradiction:

Improveflower coloration attractivenessVSAvoidvariety of flower colors

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent directly applies color changes by developing a cultivar with distinctive light green flowers with reddish-pink overtones. This unique color combination is achieved through the genetic cross between Helleborus niger and Helleborus lividus, creating a novel color phenotype that is both attractive and distinct from parent species.

Inventive Principle:

Principle #32Color changes

3Reliability

If existing Helleborus cultivars are used, then they can be grown in gardens, but they lack resistance to pests

Engineering Contradiction:

Improvepest resistanceVSAvoidpest damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the principle of converting harm into benefit by developing a cultivar that exhibits natural resistance to pests through genetic diversity. The cross-breeding process introduces genetic variability that enhances the plant's inherent defense mechanisms against pests, transforming the vulnerability of cultivated plants into a resistant variety.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
