Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current Phlox paniculata cultivars lack resistance to powdery mildew and distinct foliage and flower characteristics, limiting their landscape use and durability.

Innovation Solution

The 'Thai Pink Jade' cultivar exhibits a compact bushy habit, dark-colored stems, medium green leaves, pale pink flowers with a dark pink eye, and high resistance to powdery mildew, achieved through asexual reproduction by stem cuttings, distinguishing it from other cultivars like 'Franz Schubert' and 'Eva Cullum'.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional Phlox paniculata cultivars are used, then they have established foliage and flower characteristics, but they lack resistance to powdery mildew

Engineering Contradiction:

Improveresistance to powdery mildewVSAvoidsusceptibility to powdery mildew

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by selecting and propagating a mutant plant with altered genetic parameters that confer powdery mildew resistance. The cultivar 'Thai Pink Jade' exhibits changed biological parameters including resistance to powdery mildew, compact bushy habit, and specific flower characteristics, which are maintained through asexual reproduction by stem cuttings.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If Phlox cultivars with distinct characteristics are selected, then they have unique aesthetic features, but they may lack disease resistance

Engineering Contradiction:

Improvedistinct foliage and flower characteristicsVSAvoiddurability against disease

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent merges multiple desirable characteristics into a single cultivar: distinct spatulate-shaped petals that do not overlap, compact bushy habit, dark-colored stems, medium green leaves, pale pink flowers with dark pink eye, and high resistance to powdery mildew. These previously separate traits are combined in 'Thai Pink Jade' through selection and asexual reproduction.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cultivar exhibits self-service through its inherent resistance to powdery mildew, requiring no chemical treatments or special care to maintain health. The plant's own biological properties provide protection against disease, and its characteristics are self-maintained through stable asexual reproduction.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If Phlox plants are propagated by asexual reproduction, then characteristics are stable and reproduced true to type, but the process requires specific technical conditions

Engineering Contradiction:

Improvecharacteristics reproduced true to typeVSAvoidpropagation by stem cuttings

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent uses copying through asexual reproduction by stem cuttings to produce identical copies of the mutant plant. The cutting process creates genetic copies that reproduce the parent plant's characteristics true to type, including powdery mildew resistance, compact habit, and specific flower traits, ensuring consistency across generations.

Inventive Principle:

Principle #26Copying
