Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of variegated forms of Dianella caerulea ornamental plants in the market, limiting the aesthetic and diversity options for landscaping and container gardening.
Innovation Solution
A new and distinct perennial variety of Dianella caerulea, denominated 'DCGL', characterized by its yellow and green leaf variegation, which is stable and uniform through successive cycles of asexual propagation, providing a unique ornamental feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new variegated variety of Dianella caerulea is developed, then aesthetic appeal and diversity are enhanced, but the stability and uniformity of traits through propagation may be compromised
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific plant variety with altered foliar color parameters (yellow-green variegation) while maintaining genetic stability through controlled asexual propagation methods, thereby achieving both aesthetic enhancement and trait uniformity
Solution Approach 2:
The patent uses asexual propagation (division and tissue culture) to create exact genetic copies of the selected variegated plant, ensuring that the distinctive yellow-green foliar variegation is uniformly reproduced across multiple generations without genetic variation
2Adaptability or versatility
If variegated foliage is selected for ornamental use, then aesthetic diversity is improved, but the plant's adaptability to environmental conditions may be reduced
Solution Approach 1:
The patent applies local quality by introducing variegation specifically in the foliar tissue while maintaining the root system and other physiological structures identical to the parent species, thereby preserving environmental adaptability in the root zone while enhancing aesthetic quality in the above-ground foliage
