Solution Overview

Problem

Existing Achillea plant varieties lack a compact growth habit and early flowering trait, making them less suitable for ornamental purposes in parks and gardens, and there is a need for a variety that provides distinctive and reliable asexual reproduction.

Innovation Solution

The development of the 'Novaachdus' Achillea plant, which exhibits a compact growth habit, fine silvery-green foliage, and early flowering soft light-yellow inflorescences, distinguishable from other varieties, and can be reliably asexually reproduced through cutting, maintaining its characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing Achillea varieties are used, then they have larger plant size and later flowering, but they lack compact growth habit and early flowering traits needed for ornamental purposes

Engineering Contradiction:

Improveornamental suitabilityVSAvoidplant height

Core Design Contradiction:

Ease of operationVSLength of moving object

Solution Approach 1:

The patent applies parameter changes by selecting and breeding plants with specific phenotypic characteristics including compact growth habit, silvery-green foliage color, and early flowering time. This transforms the original Moonshine variety parameters to create Novaachdus with optimized ornamental traits suitable for landscape use.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If existing Achillea varieties are used, then they have established characteristics, but they lack the distinctive combination of compact size, silvery-green foliage, and early flowering

Engineering Contradiction:

Improveornamental versatilityVSAvoidvariety characteristics

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by developing a variety with specific localized characteristics including silvery-green foliage color, compact growth habit, and early flowering. These distinct local traits differentiate Novaachdus from other Achillea varieties and provide unique ornamental value for landscape applications.

Inventive Principle:

Principle #3Local quality

3Reliability

If asexual reproduction through cuttings is used, then trait transmission can be maintained, but the rooting process takes approximately 4.5 weeks

Engineering Contradiction:

Improvetrait transmission reliabilityVSAvoidrooting time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs disposable cuttings as a propagation method that, while requiring approximately 4.5 weeks for rooting, ensures reliable transmission of distinctive variety characteristics. This asexual reproduction method maintains genetic consistency and trait fidelity across generations, which is prioritized over faster propagation methods.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A new and distinct Achillea plant is provided that originated as a chance seedling from the open pollination of the ‘Moonshine’ variety (non-patented in the United States). Attractive fine silvery-green mature foliage is formed. The plant is early-flowering with the formation of soft light-yellow inflorescences that contrast nicely with the foliage coloration. The plant can be readily distinguished from the bright yellow inflorescences of the ‘Moonshine’ variety as well as other Achillea plants. A considerably more compact and shorter growth habit than the ‘Moonshine’ variety also is displayed. The plant is well suited for providing ornamentation in parks and gardens.
