Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Kniphofia cultivars lack a reblooming habit, early blooming, and strong upright stems, which limits their landscape use and aesthetic appeal.

Innovation Solution

The development of 'Echo Rojo', a new cultivar of Kniphofia, resulting from a controlled breeding program combining unique flower colors with a reblooming habit and strong stems, achieved through asexual reproduction by division and in vitro propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If traditional Kniphofia cultivars are grown, then they have simple blooming habits, but they lack reblooming capability and early blooming

Engineering Contradiction:

Improveblooming periodVSAvoidblooming habit

Core Design Contradiction:

Duration of action of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by selecting and breeding plants with specific genetic traits that alter the blooming parameters. The breeding program identified and propagated mutations or genetic variations that enabled early blooming (shifting the start time parameter) and reblooming capability (extending the duration parameter), transforming the traditional single-bloom habit into multiple blooming cycles throughout the season.

Inventive Principle:

Principle #35Parameter changes

2Strength

If traditional Kniphofia cultivars are grown, then they have weaker stems, but they tend to lodge and flop

Engineering Contradiction:

Improvestem strengthVSAvoidplant stability

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The breeding program changed the structural parameters of the plant by selecting for genotypes with enhanced stem thickness, improved lignification, and stronger root systems. These parameter changes in stem architecture and mechanical properties directly increased stem strength and resistance to lodging, making the plants more stable and easier to maintain in the landscape.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If new breeding traits are introduced, then reblooming and early blooming are achieved, but breeding complexity increases

Engineering Contradiction:

Improveblooming habitVSAvoidbreeding program complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The breeding program utilized self-service principles by allowing selected parent plants to self-pollinate and produce seeds that naturally exhibited the desired reblooming and early blooming traits. The breeder systematically selected offspring with these traits and propagated them, allowing the plants themselves to reproduce and pass on the desired characteristics without complex external intervention, thus managing complexity through natural reproductive processes combined with selective breeding.

Inventive Principle:

Principle #25Self-service
