Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Rhododendron varieties that exhibit dark flower color, repeat blooming, sturdiness, pest resistance, and adaptability to various environmental conditions.
Innovation Solution
The development of the Rhododendron cultivar 'ROBLEZO', which features single, self-cleaning flowers with very dark red-purple coloring, repeat blooming in spring, summer, and fall, superior landscape qualities, tolerance to pests and environmental conditions, and a strong root system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional Rhododendron varieties are used, then they may have simple blooming patterns, but they lack repeat blooming capability and dark flower colors
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control flower color intensity and blooming cycles. The cultivar 'ROBLEZO' was developed through controlled hand-pollination between selected parents to achieve the desired dark red-purple coloration and repeat blooming characteristics, transforming the original parameters of flower color and blooming duration.
2Shape
If Rhododendron varieties are bred for dark flower color and repeat blooming, then these aesthetic and functional traits are improved, but resistance to pests and environmental adaptability may be compromised
Solution Approach 1:
The patent applies universality by selecting parent plants that possess multiple desirable traits simultaneously - dark flower color, repeat blooming, and pest resistance. The breeding program aimed to create a cultivar that exhibits all these characteristics together, making the plant multi-functional in terms of aesthetic value and hardiness.
Solution Approach 2:
The patent applies composite materials by combining genetic material from two different parent plants through controlled hand-pollination. The seed parent (Azalea proprietary seedling) and pollen parent (another Azalea proprietary seedling) were selected and crossed to create a composite hybrid cultivar that inherits and expresses the desired traits from both parents.
3Adaptability or versatility
If Rhododendron varieties are developed for repeat blooming and dark colors, then landscape value is enhanced, but the complexity of breeding and propagation increases
Solution Approach 1:
The patent applies self-service through the development of self-cleaning flowers that naturally shed their petals after blooming without requiring manual intervention. This characteristic reduces maintenance complexity and allows the plant to service itself, enhancing its landscape value while minimizing the complexity of care requirements.
