Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Primula cultivar that exhibits unique characteristics such as double flowers, specific flower coloration, abundant flowering, and a compact plant habit, which are not found in existing Primula varieties.
Innovation Solution
The development of the Primula cultivar 'KERANNAWEAVE' through controlled breeding, which results in double maroon flowers with an irregular gold rim, abundant flowering, and a compact plant habit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If controlled breeding is performed to achieve double flowers with specific coloration, then flower aesthetic quality is improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by performing controlled crossing between selected parent plants before mass propagation. The breeders deliberately crossed seed parent and pollen parent to establish the desired double flower morphology and coloration traits before tissue culture multiplication, ensuring the genetic foundation is set in advance rather than attempting to modify existing plants
2Productivity
If tissue culture propagation is used to reproduce the cultivar, then propagation speed and uniformity are improved, but contamination risk and technical complexity increase
Solution Approach 1:
The patent applies self-service by using in vitro multiplication where the plant tissue culture system itself performs the propagation function. The explants undergo autonomous cell division and differentiation in the controlled culture medium, eliminating the need for manual vegetative propagation methods and reducing labor-intensive operations while maintaining genetic uniformity
3Adaptability or versatility
If selection is made based on multiple unique characteristics, then cultivar distinctiveness is improved, but selection precision and difficulty increase
Solution Approach 1:
The patent applies local quality by evaluating specific localized traits rather than overall plant characteristics. The selection focuses on distinct local features such as the double flower structure, the specific maroon and gold coloration pattern, and compact habit, allowing precise identification and selection of plants exhibiting the desired combination of traits
