Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing osteospermum cultivars lack distinct inflorescence colors, limiting diversity in flowering displays.

Innovation Solution

Development of the new cultivar 'Sunny Dark Amanda' through controlled breeding, combining the compact growth habit of 'Sunny Serena' with deeper yellow and brown disc florets, resulting in a unique and intense flower color profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing osteospermum cultivars are used, then the plant maintains familiar growth characteristics, but the inflorescence color diversity is limited

Engineering Contradiction:

Improveinflorescence color diversityVSAvoidbreeding program complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by selectively breeding to alter the color parameters of the inflorescence. The new cultivar 'Sunny Dark Amanda' exhibits deep yellow (13B-13A) ray florets and brown (200C) disc florets, representing a change in color parameters from the lighter yellow and gray of the parent 'Sunny Serena'. This demonstrates how controlled breeding can modify visual parameters to create distinct inflorescence colors while maintaining other desirable traits.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the ray floret color is deepened to create distinct inflorescence color, then aesthetic appeal is enhanced, but the similarity to existing cultivars increases

Engineering Contradiction:

Improveinflorescence color distinctivenessVSAvoidcolor accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by creating distinct color characteristics in specific parts of the inflorescence. The ray florets exhibit deep yellow color (13B base, 13A tips) while the disc florets are brown (200C), creating a localized color differentiation within the flower head. This local quality differentiation provides distinct inflorescence coloration that sets the new cultivar apart from existing varieties while maintaining internal color harmony.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If new cultivars are bred to create distinct inflorescence colors, then flower color diversity is improved, but the time required for development increases

Engineering Contradiction:

Improveinflorescence color varietyVSAvoidbreeding program duration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by establishing a controlled breeding program with clear objectives before beginning the cross. The inventor planned the breeding program to create new osteospermum cultivars with distinctly new inflorescence colors, selecting parent materials ('Sunny Serena' and proprietary seedling 30.013.01) with complementary traits before the cross was made. This preliminary planning and selection process helps streamline the breeding timeline and reduce unnecessary delays in developing new cultivars with distinct colors.
