Dianthus Cherry Vanilla Fully-Double Flower Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a distinct cultivar of carnation that combines specific traits such as fully-double flowers, velvety red petals with medium pink speckling, light pink margins, large size, and a spicy fragrance, which are not found in existing Dianthus varieties.
Innovation Solution
The development of the Dianthus 'Cherry Vanilla' cultivar, resulting from a cross between 'WP Passion' and 'Fancy Knickers', which exhibits unique characteristics like deep red flowers with light pink picotee margins, multiple flowers per peduncle, and compact habit with gray-green foliage, and is asexually propagated using traditional shoot tip cutting procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Dianthus varieties are used, then simpler flower structures are maintained, but fully-double flowers with complex petal arrangements are not achieved
Solution Approach 1:
The patent achieves fully-double flowers by nesting multiple layers of petals within each other, creating a complex rose-like structure where inner petals are surrounded by outer petals in multiple concentric layers, transforming simple single-petal structures into multi-layered floral forms
2Ease of manufacture
If solid red petals are used, then color simplicity is maintained, but velvety red coloration with medium pink speckling is not achieved
Solution Approach 1:
The patent applies local quality by creating different color patterns in different regions of the petals - the base petals have velvety red coloration with medium pink speckling, while the margins have light pink picotee edges, with each zone having distinct color characteristics that together create the complex overall appearance
3Device complexity
If single flowers per peduncle are used, then structural simplicity is maintained, but multiple flowers per peduncle are not achieved
Solution Approach 1:
The patent segments the inflorescence into multiple flowering units, with each peduncle bearing multiple individual flowers rather than a single flower, allowing the plant to produce higher overall flower productivity while maintaining manageable structural complexity through repeated modular units
4Volume of moving object
If large flower size is used, then ornamental impact is improved, but compact plant habit is not achieved
Solution Approach 1:
The patent resolves the contradiction by changing the spatial dimension of flower arrangement - large flowers are positioned vertically along upright peduncles that extend above the compact foliage mound, allowing big flowers to display above the compact plant form rather than expanding the overall plant footprint horizontally

AI summary
A new and unique plant cultivar of perennial carnation or pinks, Dianthus plant named ‘Cherry Vanilla’ with numerous, large, fully-double, lightly-fragrant flowers producing a rounded full face of velvety-red flowers. The flowers cover top to bottom of clump on well-branched stems having up to 4 flowers per stem. Petals have fine serrations, a velvety red coloration with fine speckling and margin of light pink. The plant is compact with long, thin, grey-green foliage.
