Solution Overview

Problem

Current Hibiscus rosa-sinensis cultivars lack compact, uniformly mounded growth habits and consistent flowering, making them unsuitable for container production and garden performance under varying environmental conditions.

Innovation Solution

The development of 'Samoa Wind', a new Hibiscus rosa-sinensis cultivar resulting from a cross-pollination between proprietary selections YB-1528 and YB-2336, exhibiting a compact, upright, and densely mounded growth habit with uniform, early, and abundant flowering, along with salmon pink flowers, suitable for container production and resilient garden performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional Hibiscus rosa-sinensis cultivars are used, then they may exhibit vigorous growth, but they lack compact, uniformly mounded growth habits and consistent flowering

Engineering Contradiction:

Improveplant habitVSAvoidflowering consistency

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and breeding for specific growth parameters (compactness, mound shape, branching density) and flowering parameters (flowering time, flowering duration, flower number) to transform the plant's characteristics. The breeder controlled pollination and selected progeny with desired parameter combinations, changing the genetic parameters to achieve both compact uniform shape and reliable flowering.

Inventive Principle:

Principle #35Parameter changes

2Volume of moving object

If Hibiscus plants are bred for compact growth habit, then container production suitability improves, but flower size and vigor may be reduced

Engineering Contradiction:

Improveplant volumeVSAvoidflower vigor

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The patent applies local quality by creating different characteristics in different parts of the plant - the overall plant structure is compact and mounded suitable for containers, while the flower portions maintain full size, vibrant color, and vigor. The breeding selected for compact internode spacing and dense branching throughout the plant, while ensuring flowers themselves retained large size and strong development.

Inventive Principle:

Principle #3Local quality

3Loss of time

If Hibiscus plants are bred for early flowering, then market readiness improves, but overall plant development and hardiness may be compromised

Engineering Contradiction:

Improvetime to floweringVSAvoidgarden performance

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent applies preliminary action by conducting controlled breeding and selection in advance to establish early-flowering genetics in the cultivar. The plant was bred to have pre-programmed early flowering capability through selective breeding of parent plants that exhibited both early flowering and good hardiness, then maintained these traits through careful propagation and selection of true-to-type plants.
