Solution Overview

Problem

There is a need for new Caladium plant cultivars with uniform plant habit, exceptional container and garden performance, and unique leaf coloration that can reproduce stably and consistently under varying environmental conditions.

Innovation Solution

The development of the Caladium x hortulanum cultivar 'ICE 2319-293', which is the result of a cross-pollination between Caladium x hortulanum 'White Wonder' and 'Highlighter', exhibiting intermediate height, dense and bushy growth, rapid growth rate, and distinctive variegated leaf colors, achieved through asexual reproduction by 'chipping' tubers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cross-pollination is performed to create new Caladium cultivars with unique leaf coloration, then leaf color variety is improved, but genetic stability and true-to-type reproduction may deteriorate

Engineering Contradiction:

Improveleaf color varietyVSAvoidgenetic stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The tuber is segmented into multiple pieces, each containing an axillary bud and cortical tissue, for asexual reproduction. This segmentation allows propagation while maintaining genetic stability of the selected phenotype.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Asexual reproduction by tuber chipping creates genetic copies of the selected plant, ensuring true-to-type reproduction and stable inheritance of unique leaf coloration without genetic variation.

Inventive Principle:

Principle #26Copying

2Stability of the object's composition

If asexual reproduction by tuber chipping is used, then genetic stability and true-to-type reproduction are improved, but propagation speed and productivity may deteriorate

Engineering Contradiction:

Improvetrue-to-type reproductionVSAvoidpropagation speed

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The tuber is divided into multiple segments, each capable of independent growth. This increases the number of plants produced from a single tuber, enhancing propagation productivity while maintaining genetic stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Tuber segments are prepared in advance with axillary buds and cortical tissue before planting, accelerating the propagation process while ensuring genetic fidelity to the parent plant.

Inventive Principle:

Principle #10Preliminary action

3Volume of moving object

If intermediate height and dense bushy habit are selected, then container performance is improved, but growth rate may deteriorate

Engineering Contradiction:

Improveplant compactnessVSAvoidgrowth rate

Core Design Contradiction:

Volume of moving objectVSProductivity

Solution Approach 1:

The plant exhibits dense bushy growth habit with intermediate height, concentrating biomass in a compact form suitable for containers while maintaining vigorous growth rate through selective breeding.

Inventive Principle:

Principle #3Local quality
