Solution Overview

Problem

There is a need for a distinct cultivar of Angelonia augustifolia that exhibits unique characteristics such as upright and freely branching habits, red purple and purple bi-colored flowers, which differ from the parent selection and other cultivars like Adebic in flower color, while maintaining stability through asexual reproduction.

Innovation Solution

The cultivar 'Zebra' is a naturally occurring branch mutation of Angelonia augustifolia, characterized by its upright and freely branching habit, red purple and purple bi-colored flowers, and is propagated through cuttings, maintaining its unique traits under various environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a new cultivar with unique flower color is developed through mutation, then flower color diversity is improved, but genetic stability may worsen

Engineering Contradiction:

Improveflower color diversityVSAvoidgenetic stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by selecting for a specific phenotypic variation (flower color) that arose through natural mutation. The unique bi-colored flower pattern (red-purple and purple) represents a change in the color parameters of the parent selection's blue flowers. This principle resolves the contradiction by capturing a specific parameter change (color) while maintaining overall genetic stability through controlled propagation.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies copying by propagating the mutated plant through cuttings to create genetically identical copies. This asexual reproduction method ensures that the unique flower color trait is replicated exactly in successive generations, maintaining genetic stability while preserving the desired color diversity. The copied plants are true-to-type, resolving the tension between variation and stability.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If environmental conditions are varied to test phenotype stability, then adaptability is improved, but measurement precision of unique traits may worsen

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidtrait consistency

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies inversion by reversing the typical approach: instead of testing many cultivars under one environment, it exposes this single cultivar to multiple environmental conditions (temperature ranges, light intensities, cultural practices) to demonstrate its phenotypic stability. This inverted approach proves that the unique traits remain consistent across varying conditions, resolving the contradiction between adaptability and measurement precision.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent applies this principle by using multiple short-term growth cycles under different environmental conditions to test stability, rather than maintaining long-term complex controlled experiments. The plants are grown, evaluated, and replaced in successive generations, allowing efficient assessment of environmental adaptability while maintaining precise measurement of trait consistency through repeated observation of the same cultivar.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
