Solution Overview

Problem

The existing Osteospermum cultivars lack a variety that combines compact growth habit, high heat tolerance, and specific inflorescence characteristics, such as creamy white and yellow coloration, with stable reproduction across generations.

Innovation Solution

The cultivar 'DEL COM YS' of Osteospermum ecklonis exhibits small daisy-type inflorescences, freely flowering compact growth, creamy white with creamy yellow underside and gray-green center, and high heat tolerance, distinguishing it from other varieties like 'WC 32/44' with its unique combination of traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Osteospermum cultivars are used, then they have basic flowering characteristics, but they lack the combination of compact growth habit, high heat tolerance, and specific inflorescence characteristics

Engineering Contradiction:

Improveheat toleranceVSAvoidstability of reproduction

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and stabilizing specific genetic parameters through repeated asexual reproduction. The cultivar 'DEL COM YS' was developed by maintaining consistent genotypic parameters across multiple generations of cutting propagation, resulting in stable expression of heat tolerance, compact growth habit, and specific inflorescence characteristics including creamy white ray florets with yellow undersides and gray-green disc florets.

Inventive Principle:

Principle #35Parameter changes

2Temperature

If Osteospermum cultivars are bred for heat tolerance, then they can withstand higher temperatures, but they may lose other desirable traits like growth habit and inflorescence characteristics

Engineering Contradiction:

Improveheat toleranceVSAvoidgrowth habit

Core Design Contradiction:

TemperatureVSShape

Solution Approach 1:

The patent merges multiple desirable traits into a single cultivar through selective breeding and asexual propagation. The cultivar 'DEL COM YS' combines heat tolerance with compact growth habit (35 cm height, 88 cm spread), specific inflorescence morphology (small daisy-type flowers 4.75 cm diameter), and distinctive coloration (cream white ray florets with yellow undersides and gray-green disc florets) into one stable genetic line.

Inventive Principle:

Principle #5Merging (Combining)

3Area of moving object

If Osteospermum cultivars are bred for larger inflorescences, then they have more prominent flowers, but they may lose compact growth habit and heat tolerance

Engineering Contradiction:

Improveinflorescence sizeVSAvoidheat tolerance

Core Design Contradiction:

Area of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by optimizing inflorescence characteristics within specific parameters rather than maximizing size. The cultivar 'DEL COM YS' features small daisy-type inflorescences (4.75 cm diameter) with distinctive local color variations - creamy white ray florets with yellow undersides and gray-green disc florets - maintaining compact plant architecture and heat tolerance while providing visually interesting floral details.
