Compact Mandevilla Cultivar With Dense Branching and Bright 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 plant habit.
Innovation Solution
A new Mandevilla cultivar, 'QD-94', resulting from a controlled cross-pollination of proprietary selections, exhibits a compact and upright growth habit, dense branching, dark green leaves, and bright purplish pink flowers with yellow centers, distinguishing it from other varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Mandevilla varieties are used, then they have larger flowers, but they lack compact growth habit and dense branching
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific growth parameters including compact stature (20-40 cm height), dense branching frequency, and reduced internode length. This transforms the plant's morphological parameters to achieve a compact yet bushy habit that differs from traditional trailing Mandevilla varieties
2Ease of manufacture
If traditional Mandevilla varieties are used, then they have established flower colors, but they lack bright purplish pink flowers with yellow centers
Solution Approach 1:
The patent applies local quality by creating distinct color zones within the flower structure: bright purplish pink outer petals (throat region) combined with bright yellow centers (throat base). This spatial differentiation of color properties within a single flower achieves visual complexity while maintaining breeding stability
3Volume of moving object
If Mandevilla plants are bred for compact size, then they have reduced growth volume, but they may have reduced flowering capacity
Solution Approach 1:
The patent applies segmentation by dividing the plant into densely packed modular units of compact growth, where each segment produces flowers. The freely branching habit creates multiple independent flowering segments throughout the compact plant, ensuring high flowering capacity within limited volume
