Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for a new and distinct Vanda cultivar that exhibits specific and stable ornamental characteristics such as light pink sepals and lateral petals with darker shading, purple reticulate venation, a dark pink central labellum lobe, and a light pink column, which are not observed under all environmental conditions but remain true to type through asexual reproduction.

Innovation Solution

The cultivar 'SPCDW1602' is developed through mericloning, a method of asexual reproduction, which stabilizes the unique features observed in a naturally occurring mutation of Vanda 'SPCDW0902', ensuring these characteristics are consistent across generations and adaptable to various environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a naturally occurring mutation is selected for commercial production, then unique ornamental characteristics are obtained, but environmental sensitivity causes phenotype variation

Engineering Contradiction:

Improvecommercial production suitabilityVSAvoidphenotype stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by utilizing asexual reproduction (mericloning) to maintain consistent genetic parameters across generations. This method preserves the unique ornamental characteristics of the mutation while eliminating environmental sensitivity effects, ensuring stable phenotype expression in commercial production.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If environmental conditions vary, then plant adaptability is demonstrated, but ornamental characteristics may change

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidornamental characteristic consistency

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent resolves this contradiction by changing the reproductive parameter from sexual to asexual (mericloning). This ensures that ornamental characteristics remain consistent across varying environmental conditions while maintaining the plant's adaptability to different growing zones and temperatures.

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If mericloning is used for propagation, then genetic stability is achieved, but propagation time and complexity increase

Engineering Contradiction:

Improvegenetic stabilityVSAvoidpropagation time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by establishing the mericloning propagation system in advance and selecting suitable planting times. This allows for efficient propagation while maintaining genetic stability, reducing the time loss associated with achieving consistent ornamental characteristics through traditional sexual reproduction methods.
