Solution Overview

Problem

There is a need for a new cultivar of Vanda that exhibits unique and stable sepal and petal coloration with a light yellow background and purple spotting, as existing varieties lack distinct and consistent coloration under varying environmental conditions.

Innovation Solution

The cultivar 'SPCDW1320' is developed through a planned breeding program, resulting in a Vanda hybrid with a light yellow background and purple spotting on sepals and petals, along with a very dark purple floral lip, which remains stable across different environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new Vanda cultivar is developed through planned breeding, then unique and stable coloration is achieved, but breeding time and complexity increase

Engineering Contradiction:

Improvecoloration stabilityVSAvoidbreeding time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by conducting a planned breeding program that anticipates the desired coloration traits before full expression is needed. The crossing of seed parent Vanda 'M58N' with pollen parent Vanda 'S399' was deliberately designed to produce the specific light yellow background with purple spotting pattern, allowing the trait to be established early and propagated through tissue culture and vegetative cuttings to ensure stability across generations.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If environmental conditions vary, then phenotype may change, but genotype remains stable

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidcoloration consistency

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies inversion by reversing the typical concern about environmental variability. Rather than trying to eliminate environmental influence on phenotype, the invention accepts that phenotype may vary with environment while ensuring that the genotype remains stable. The unique coloration traits are genetically fixed in the cultivar 'SPCDW1320', and this genetic stability is maintained through controlled propagation methods, allowing the plant to adapt to different environments without losing its defining characteristics.

Inventive Principle:

Principle #13The other way round (Inversion)

3Manufacturing precision

If tissue culture propagation is used, then true-to-type reproduction is achieved, but propagation complexity increases

Engineering Contradiction:

Improvereproduction fidelityVSAvoidpropagation system complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses tissue culture as an intermediary propagation method between traditional seed propagation and vegetative cutting. The tissue culture process acts as a mediator that produces plantlets genetically identical to the parent plant, ensuring true-to-type reproduction of the unique coloration traits. This intermediary step allows for controlled multiplication of the cultivar while maintaining genetic fidelity, and the resulting plantlets can then be further propagated through simpler vegetative cuttings.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

‘SPCDW1320’ is a distinctive variety of Vanda which is characterized by the light-yellow sepal and petal background coloration, purple spotting and a broad rim of purple on each of the sepals and petals, with the light yellow background being more prominent in the two lateral sepals than in the two petals and the dorsal sepal. The new variety is a Vanda, typically produced as an indoor ornamental plant.
