Solution Overview

Problem

There is a need for new compact and vigorous Phlox plants with numerous small flowers that can thrive under various environmental conditions and cultural practices, while maintaining distinct characteristics across generations.

Innovation Solution

A new cultivar of Phlox paniculata, 'Appottwh', was developed through planned breeding, exhibiting a broadly upright and compact growth habit, numerous small purplish-white flowers, long flowering period, and good garden performance, achieved through asexual reproduction by terminal cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional Phlox breeding methods are used, then flower size and color variation are maintained, but plant compactness and vigor are reduced

Engineering Contradiction:

Improveplant compactnessVSAvoidflower size

Core Design Contradiction:

ShapeVSQuantity of substance

Solution Approach 1:

The breeding program systematically altered genetic parameters through controlled cross-pollination between specific parent selections (047-11-K121-05 and 047-08-007), selecting for the optimal combination of compact plant architecture and appropriate flower size characteristics in the resulting cultivar 'Appottwh'

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The new cultivar 'Appottwh' achieves multi-functionality by simultaneously providing compact plant habit for space-efficient gardening, vigorous growth for sustained flowering, and numerous flowers of appropriate size, making it suitable for various garden applications

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If Phlox plants are bred for vigorous growth, then plant health improves, but stability of unique features across generations decreases

Engineering Contradiction:

Improveplant vigorVSAvoidfeature stability

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

Extensive preliminary testing and evaluation were conducted during the breeding program, including growing multiple generations from the cross-pollination event and assessing various characteristics before finalizing the cultivar description, ensuring that vigor and feature stability are both established before release

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The breeding program incorporated continuous feedback loops where progeny were evaluated against desired characteristics, and selections were made based on performance observations, allowing refinement of the cultivar to achieve both vigor and stability

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If Phlox plants are developed for adaptability to environmental conditions, then garden performance improves, but distinct characteristics may be diluted

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidcharacteristic distinctiveness

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The cultivar 'Appottwh' exhibits local quality by maintaining distinct local characteristics (flower color, plant habit) while demonstrating adaptability to various environmental conditions, allowing it to thrive in different garden settings without losing its defining features

Inventive Principle:

Principle #3Local quality
