Solution Overview

Problem

There is a need for a distinct and commercially viable cultivar of Dracaena reflexa with unique ornamental characteristics that can reproduce stably and maintain its variegated foliage under varying environmental conditions.

Innovation Solution

The cultivar 'IDEA1010' of Dracaena reflexa, identified through a chance mutation, exhibits stable unique variegated foliage and long, narrow leaves, differing from the parent variety, and is propagated via vegetative cuttings, maintaining its characteristics across generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a naturally occurring mutation is selected for variegated foliage, then unique ornamental characteristics are achieved, but stability of reproduction across generations may be compromised

Engineering Contradiction:

Improvevariegated foliage patternVSAvoidreproduction stability

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The patent utilizes vegetative cuttings (a form of asexual reproduction) to propagate the mutant plant, creating genetically identical copies that preserve the variegated foliage pattern across generations without the need for complex breeding programs or genetic modification techniques

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The plant's natural vegetative propagation capability is harnessed to maintain and reproduce the unique variegated characteristics automatically, with the plant serving its own propagation needs through cuttings that root and grow into identical specimens

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If environmental conditions vary (temperature, light intensity, day length), then phenotypic expression may change, but genotype remains constant

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidphenotypic consistency

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The patent acknowledges and utilizes the local quality variation in phenotypic expression under different environmental conditions, where the same genotype expresses slightly different foliage characteristics in response to local environmental factors like temperature and light intensity variations

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of trying to control environmental conditions to maintain phenotypic consistency, the patent inverts the approach by selecting and propagating a genotype that naturally tolerates environmental variation, accepting phenotypic diversity as a characteristic of the cultivar

Inventive Principle:

Principle #13The other way round (Inversion)

3Stability of the object's composition

If vegetative propagation is used for reproduction, then genetic stability is maintained, but time to produce rooted plantlets increases

Engineering Contradiction:

Improvegenetic stabilityVSAvoidpropagation time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent employs preliminary action by preparing and treating cuttings in advance with appropriate conditions (temperature control, humidity management) to accelerate rooting, so that the genetic stability benefit of vegetative propagation is achieved with minimized time delay

Inventive Principle:

Principle #10Preliminary action
