Solution Overview

Problem

There is a need for a new Coleus cultivar that exhibits unique characteristics such as deeply lobed, undulating leaves, a wide mix of colors, compact growth habit, and short internodes, which are not met by existing varieties like 'Bienvenue' and 'Super Ducks Foot', and are stable across different environmental conditions.

Innovation Solution

The cultivar 'MD CURPGF06' is developed through terminal cuttings, showcasing deeply lobed, undulating leaves with a mix of pink and pale yellow colors, compact growth, and short internodes, distinct from its parent 'Bienvenue' and 'Super Ducks Foot', with specific botanical and horticultural traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the Coleus plant is bred for unique foliage characteristics (deeply lobed leaves, wide color mix), then the aesthetic value and distinctiveness improve, but the plant height and leaf size become reduced

Engineering Contradiction:

Improvefoliage shape and color patternVSAvoidplant height and leaf length

Core Design Contradiction:

ShapeVSLength of moving object

Solution Approach 1:

The patent applies local quality by developing a cultivar with highly differentiated local characteristics in the foliage - deeply lobed leaves with specific undulating patterns, and a wide mix of colors (pink, pale yellow, darker green margin) concentrated in specific regions of the leaf, while accepting reduced overall plant and leaf dimensions as a trade-off for these enhanced local aesthetic qualities

Inventive Principle:

Principle #3Local quality

2Ease of operation

If the Coleus plant is selected for compact growth habit and short internodes, then the suitability for container gardening improves, but the overall plant vigor and leaf expansion are reduced

Engineering Contradiction:

Improvesuitability for container gardeningVSAvoidleaf expansion and plant vigor

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent applies parameter changes by selectively modifying the internode length parameter to be short (creating compact growth) while maintaining adequate leaf expansion through optimized foliage characteristics. This parameter adjustment makes the plant suitable for container gardening (improved ease of operation) while preserving sufficient leaf development for aesthetic appeal

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the Coleus plant is bred for stable phenotype across environmental conditions, then the reliability of foliage appearance improves, but the adaptability to different growing conditions is reduced

Engineering Contradiction:

Improvephenotype stabilityVSAvoidenvironmental adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies inversion by selecting for genotype stability that produces consistent phenotype expression across varying environmental conditions. Rather than trying to maximize adaptability to all conditions, the cultivar is bred to maintain its distinctive foliage characteristics (deeply lobed shape, color pattern) reliably across a range of standard growing conditions, trading some environmental flexibility for phenotype consistency

Inventive Principle:

Principle #13The other way round (Inversion)
