Solution Overview

Problem

There is a need for a new Mandevilla cultivar that exhibits a compact growth habit, dark green and glossy foliage, large white flowers lightly suffused with pink, and continuous flowering, which are not adequately addressed by existing Mandevilla sanderi varieties.

Innovation Solution

The cultivar 'OOSMANWHI1' is developed through asexual reproduction by softwood stem cuttings, showcasing a unique combination of compact growth, dark green glossy foliage, large white flowers with a pink undertone, and continuous flowering, distinguishing it from other Mandevilla varieties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If Mandevilla sanderi varieties are selected for flower color variation, then flower color diversity is improved, but growth habit compactness deteriorates

Engineering Contradiction:

Improveflower color diversityVSAvoidgrowth habit compactness

Core Design Contradiction:

Quantity of substanceVSShape

Solution Approach 1:

The patent applies local quality by selecting for specific localized traits in the 'OOSMANWHI1' cultivar - specifically compact growth habit and continuous flowering ability - while maintaining flower color characteristics. This selective breeding approach improves desired local qualities without requiring overall plant size reduction, resolving the contradiction between flower color diversity and growth compactness.

Inventive Principle:

Principle #3Local quality

2Loss of time

If Mandevilla sanderi varieties are selected for flowering earliness, then flowering time is improved, but flowering persistence deteriorates

Engineering Contradiction:

Improveflowering timeVSAvoidflowering persistence

Core Design Contradiction:

Loss of timeVSDuration of action of stationary object

Solution Approach 1:

The patent applies dynamics by breeding for continuous flowering ability in the 'OOSMANWHI1' cultivar, transforming the static flowering pattern into a dynamic, ongoing process. The plant progresses through multiple flowering cycles throughout the growing season, with successive batches of flowers opening continuously from spring to fall, thereby resolving the contradiction between early flowering and flowering persistence.

Inventive Principle:

Principle #15Dynamics

3Area of moving object

If Mandevilla sanderi varieties are selected for flower size, then flower dimensions are improved, but flowering abundance deteriorates

Engineering Contradiction:

Improveflower sizeVSAvoidflowering abundance

Core Design Contradiction:

Area of moving objectVSQuantity of substance

Solution Approach 1:

The patent applies merging by combining two previously separate traits into one unified cultivar: large flower size and abundant flowering. The 'OOSMANWHI1' cultivar produces both sizable flowers (5-6 cm diameter) and maintains high flowering abundance through continuous blooming, merging these contrasting qualities into a single plant that exhibits both characteristics simultaneously.

Inventive Principle:

Principle #5Merging (Combining)
