Solution Overview

Problem

There is a need for new Mandevilla cultivars with large and uniquely colored flowers, as existing varieties may lack desired traits such as flower color variation and leaf size differences.

Innovation Solution

The cultivar 'Sunparacopapi' is developed through cross-pollination of proprietary Mandevilla hybrida selections, exhibiting unique characteristics like pink-colored flowers, larger leaves, and a vining habit, distinguishing it from parent and similar cultivars.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If cross-pollination is performed to create new Mandevilla cultivars with large and uniquely colored flowers, then flower color and size are improved, but genetic stability and reproduction consistency may deteriorate

Engineering Contradiction:

Improveflower color and sizeVSAvoidgenetic stability

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The inventors performed preliminary selection and characterization of the F1 hybrid plant before formal cultivar registration. The plant was propagated asexually multiple times and evaluated for stability of its unique traits (pink flowers with white throat, large leaf size) across generations, ensuring genetic consistency was established before the cultivar was officially recognized.

If selection is made for large flowers, then flower size is improved, but flowering period duration may deteriorate

Engineering Contradiction:

Improveflower sizeVSAvoidflowering period

Core Design Contradiction:

Volume of moving objectVSDuration of action of moving object

Solution Approach 1:

The F1 hybrid exhibits a combination of parameters that balances flower size and flowering duration. The plant produces large flowers (6-7 cm diameter) while maintaining an extended flowering period from spring through autumn. This was achieved through the specific cross between MH-7 and M37-1, which combined genetic traits for both large flower size and prolonged flowering capability.

3Shape

If selection is made for unique flower color, then color distinctiveness is improved, but adaptability to different environmental conditions may deteriorate

Engineering Contradiction:

Improveflower color distinctivenessVSAvoidenvironmental adaptability

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The F1 hybrid plant exhibits self-service characteristics in maintaining its unique pink flower color with white throat across varying environmental conditions. The plant's genetic composition provides inherent stability that allows it to express its distinctive coloration consistently whether grown in different locations or under varying cultural practices, reducing the need for environmental control.

Inventive Principle:

Principle #25Self-service
