Compact Mandevilla Cultivar With Dense Branching and Showy Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mandevilla plants lack compact and freely branching varieties with attractive flowers, particularly in terms of flower color and petal arrangement.
Innovation Solution
A new Mandevilla cultivar, 'QD-80', is developed through controlled cross-pollination, exhibiting a compact, broadly upright growth habit, dense branching, dark green leaves, and bright purplish red flowers that extend beyond the foliar plane, distinguishing it from other cultivars like 'QD8' and 'QD5'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Mandevilla varieties are used, then they have larger size and less dense branching, but they lack compact and bushy appearance with freely branching habit
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific growth parameters that result in compact size (20-30 cm height), dense branching habit, and bushy appearance. The cultivar 'QD-80' exhibits these altered growth parameters compared to conventional varieties, achieving the desired compact and freely branching form through controlled breeding programs that modify plant architecture parameters.
2Ease of manufacture
If conventional Mandevilla varieties are used, then they have red-colored flowers with imbricate petals, but they lack bright purplish red flowers held beyond the foliar plane
Solution Approach 1:
The patent applies local quality by developing flowers with specific local characteristics: bright purplish red coloration (distinct from standard red), non-imbricate petal arrangement, and positioning that extends beyond the foliar plane. These localized floral traits differentiate 'QD-80' from conventional varieties while maintaining overall plant health and flowering capacity.
3Shape
If Mandevilla plants are bred for compact size, then they achieve bushy appearance, but they may reduce flowering capacity
Solution Approach 1:
The patent applies dynamics by creating a balanced plant architecture where compact size and dense branching coexist with vigorous flowering. The cultivar 'QD-80' dynamically allocates resources to maintain both compact form (20-30 cm height) and high flowering capacity (freely flowering habit with numerous blooms), achieving a dynamic equilibrium between structural compactness and reproductive productivity.
