Solution Overview

Problem

There is a need for new and distinct cultivars of Geranium with attractive flowers and strong growth habits that can perform well in various environmental conditions and cultural practices.

Innovation Solution

The cultivar 'Thumbling Hearts' is developed through planned breeding, combining the traits of Geranium cinereum cultivars Purple Pillow and Ballerina, exhibiting an upright and spreading plant habit, dark green leaves, and light pink flowers with red-purple venation and centers, which are stable and reproduce true to type through asexual reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new Geranium cultivars are created through planned breeding programs, then attractive flowers and strong growth habits are achieved, but the breeding process requires controlled environments and time investment

Engineering Contradiction:

Improvegarden performanceVSAvoidbreeding program duration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The breeding program conducted planned cross-pollination in July 2002 before the desired cultivar was discovered in February 2003, preparing the genetic material in advance to achieve the target traits of strong growth habit and attractive flowers

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cultivar was reproduced through asexual reproduction by divisions, creating true-to-type copies that maintain the unique characteristics discovered in the original plant, allowing rapid propagation without time-consuming sexual reproduction

Inventive Principle:

Principle #26Copying

2Stability of the object's composition

If the cultivar is selected as a single flowering plant from progeny, then unique characteristics are stabilized, but the selection process requires controlled environment and careful observation

Engineering Contradiction:

Improvegenotype stabilityVSAvoidcontrolled environment requirements

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The plant exhibited stable inheritance of its unique characteristics through asexual reproduction by divisions, allowing it to reproduce true-to-type without requiring complex controlled environments for each generation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The single flowering plant was copied through asexual reproduction, creating identical genetic copies that maintain the stable genotype discovered during selection in the controlled environment

Inventive Principle:

Principle #26Copying

3Ease of manufacture

If flower color is modified through breeding, then unique flower characteristics are achieved, but the traits may vary with environmental conditions such as temperature and light intensity

Engineering Contradiction:

Improveflower color consistencyVSAvoidenvironmental tolerance

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent acknowledges that flower color may vary with environmental parameters such as temperature and light intensity, but the genotype remains stable, indicating that the breeding program optimized for genetic consistency while accepting environmental influences on phenotypic expression

Inventive Principle:

Principle #35Parameter changes
