Solution Overview

Problem

Existing Regal Geranium cultivars require cooling treatment for flower development, limiting their adaptability and efficiency in various environmental conditions.

Innovation Solution

The development of the 'Regsur' cultivar of Pelargonium grandiflorum, which exhibits an upright and mounded growth habit, vigorous growth, early and frequent flowering, and large dark red-colored flowers, and does not require cooling treatment for flower development, achieved through a controlled breeding program in Dresden, Germany.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cooling treatment is applied for flower development in existing Regal Geranium cultivars, then flower development is achieved, but production time is extended and adaptability to various environmental conditions is limited

Engineering Contradiction:

Improveflower development reliabilityVSAvoidproduction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by modifying the physiological requirements of the geranium cultivar through breeding. The new cultivar 'Regsur' has been bred to change the temperature parameter threshold for flower initiation, allowing it to flower without the cooling treatment that existing cultivars require. This eliminates the time loss associated with cooling treatment while maintaining reliable flower development.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If cooling treatment is required for flower development, then flower initiation is triggered, but adaptability to varying environmental conditions is reduced

Engineering Contradiction:

Improveflower initiation reliabilityVSAvoidenvironmental adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent achieves universality by breeding a cultivar that can initiate flowers under multiple environmental conditions without requiring specific cooling treatment. The new cultivar 'Regsur' possesses the universal ability to flower in diverse temperature regimes, making it adaptable to various environmental conditions while maintaining reliable flower initiation, thus serving multiple environmental contexts with a single cultivar.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If cooling treatment is applied to existing cultivars, then flower development proceeds, but production costs increase

Engineering Contradiction:

Improveflower development consistencyVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent reduces production costs by changing the physiological parameters of the geranium cultivar through breeding. The new cultivar 'Regsur' has been modified to eliminate the requirement for cooling treatment, thereby removing the associated production costs while maintaining consistent and reliable flower development. This parameter change in the cultivar's flowering response directly reduces manufacturing expenses.

Inventive Principle:

Principle #35Parameter changes
