Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current Geranium cultivars lack early flowering and semi-double flower characteristics, with limited options for varieties exhibiting dark green foliage and moderate growth habits.

Innovation Solution

Development of the new Geranium cultivar 'Genbored' through induced hybridization of proprietary selections Pelargonium×hortorum G145 and D85, resulting in red, large semi-double flowers with dark green zonation and an early flower response, suitable for asexual reproduction by terminal cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional Geranium cultivars are used, then breeding options are limited, but early flowering and semi-double flower characteristics are not achieved

Engineering Contradiction:

Improveflowering timeVSAvoidbreeding options

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent combines multiple desirable traits from different parent plants through hybridization to create a new cultivar that exhibits early flowering, semi-double flowers, and dark green foliage with zonation pattern, resolving the limitation of conventional cultivars that lack these combined characteristics

Inventive Principle:

Principle #5Merging (Combining)

2Speed

If Geranium 'Faro' is used, then flower color is achieved, but flower response time is delayed and flower size is smaller

Engineering Contradiction:

Improveflower response timeVSAvoidflower size and color intensity

Core Design Contradiction:

SpeedVSShape

Solution Approach 1:

The new cultivar 'Genbored' exhibits parameter improvements over 'Faro' including earlier flowering response, larger flower size (5.0 cm diameter vs. smaller), and enhanced color intensity (pink-red vs. less intense), achieved through controlled hybridization and selection

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If parent G145 is used, then zonation pattern is achieved, but zonation intensity is darker and flower color is less pink

Engineering Contradiction:

Improvezonation pattern stabilityVSAvoidzonation lightness and flower pinkness

Core Design Contradiction:

Stability of the object's compositionVSShape

Solution Approach 1:

The hybridization process selectively combines the zonation pattern trait from parent G145 with other desirable traits, resulting in a lighter zonation pattern that maintains stability while improving overall plant characteristics including darker red flowers and earlier flowering

Inventive Principle:

Principle #3Local quality

4Speed

If parent D85 is used, then flower response is achieved, but flowering time is later and flower color is darker red

Engineering Contradiction:

Improveflower response timingVSAvoidflower color shade

Core Design Contradiction:

SpeedVSShape

Solution Approach 1:

Instead of directly using parent D85 which has later flowering and darker red flowers, the breeding program uses D85 as a pollen parent in a controlled cross that inverts or modifies these traits, producing offspring with earlier flowering response and lighter red-pink flower colors while maintaining the desired zonation pattern

Inventive Principle:

Principle #13The other way round (Inversion)
