Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a Begonia hybrid cultivar that exhibits unique and stable characteristics such as distinctive foliage, root hardiness, large leaf size, and vibrant flower colors, which are not met by existing varieties under varying environmental conditions.
Innovation Solution
The 'Dark Side of the Moon' Begonia hybrid cultivar, developed through open-pollination, showcases distinctive green-black foliage, maroon undersides, root hardiness, large leaf size, cherry red to medium pink and white flowers, and a rounded plant form, which are stable across different environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Begonia hybrid varieties are used, then basic horticultural characteristics are maintained, but unique and stable characteristics such as distinctive foliage, root hardiness, large leaf size, and vibrant flower colors are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled breeding. The inventor crossed two different Begonia hybrid varieties to combine desirable traits, then selected offspring exhibiting stable expression of distinctive foliage color, root hardiness, large leaf size, and vibrant flower colors. This systematic parameter selection and stabilization resolves the contradiction by achieving reliable expression of unique characteristics while maintaining adaptability through genetic diversity.
Solution Approach 2:
The patent applies composite materials by creating a composite genetic structure through hybridization. The new cultivar combines genetic material from two different Begonia hybrid parent varieties, resulting in a composite genotype that expresses multiple unique characteristics simultaneously. This composite genetic composition provides both the stability of distinctive traits and the adaptability to environmental variations, resolving the technical contradiction.
2Productivity
If leaf cutting propagation is used for asexual reproduction, then new plants are produced, but time and resource investment increase
Solution Approach 1:
The patent applies preliminary action by performing asexual reproduction through leaf cuttings during the optimal growing season when environmental conditions favor rapid rooting. The inventor selected healthy parent plants and took cuttings under favorable temperature and humidity conditions, which accelerated the rooting process. This preliminary timing strategy reduces the time loss associated with propagation while maintaining productivity.
3Adaptability or versatility
If the cultivar is grown under varying environmental conditions, then adaptability is tested, but phenotypic variance may occur
Solution Approach 1:
The patent applies copying by using asexual reproduction through leaf cuttings to create genetically identical copies of the selected parent plant. This cloning approach ensures that the unique characteristics—distinctive green-black foliage with maroon undersides, root hardiness, large leaf size, cherry red to medium pink and white flowers, and rounded plant form—are replicated exactly in offspring. The genetic copying maintains phenotypic consistency while the cultivar demonstrates adaptability across environmental conditions.
