Duesspcherry Impatiens Cultivar Resolving Garden Performance Contradictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing New Guinea Impatiens cultivars lack uniformity and attractive flower colors, with limited garden performance and compact growth habits, particularly in varying environmental conditions.
Innovation Solution
A new cultivar, 'Duesspcherry', with an upright, spreading, and vigorously growing habit, featuring dark green leaves and deep red-purple flowers, bred through asexual reproduction of a naturally occurring mutation of Impatiens × hybrida, exhibiting stable traits across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing New Guinea Impatiens cultivars are grown in varying environmental conditions, then their growth and flowering performance deteriorates, but maintaining uniform environmental conditions increases cultivation complexity and cost
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through asexual reproduction of a naturally occurring mutation. The cultivar 'Duesspcherry' exhibits stable phenotypic parameters (compact growth, deep red-purple flowers, dark green leaves) that maintain consistency across varying environmental conditions, resolving the contradiction between reliability and adaptability.
2Volume of moving object
If existing New Guinea Impatiens cultivars are bred for compact growth, then plant size is reduced, but flower color attractiveness and uniformity are compromised
Solution Approach 1:
The patent applies segmentation by isolating a single naturally occurring mutation from a population through asexual reproduction. This segmentation approach captured the specific genetic variation responsible for the desirable trait combination (compact size + deep red-purple flower color + dark green leaves), ensuring uniformity while maintaining compact growth characteristics.
Solution Approach 2:
The patent changes the genetic parameters by selecting a natural mutation that simultaneously affects multiple traits: plant compactness, flower color intensity (deep red-purple), and leaf color (dark green). This parameter change resolves the contradiction between compact size and color uniformity by fixing the traits at the genetic level through asexual propagation.
3Ease of manufacture
If existing New Guinea Impatiens cultivars produce magenta or cherry red flowers, then flower color variety is limited, but breeding for new colors may compromise other desirable traits
Solution Approach 1:
The patent applies self-service by utilizing a naturally occurring mutation that spontaneously produced the desirable deep red-purple flower color without requiring complex breeding interventions. The plant self-generated the novel trait through natural mutation, and the inventor simply needed to identify and propagate it through asexual reproduction, maintaining breeding simplicity while achieving new color variety.
4Loss of time
If existing New Guinea Impatiens cultivars are grown for early flowering, then flowering time is advanced, but plant vigor and overall garden performance are reduced
Solution Approach 1:
The patent applies parameter changes by selecting a mutation that alters the flowering time parameter while maintaining or enhancing other performance parameters. The cultivar 'Duesspcherry' achieves early flowering (reducing time loss) while simultaneously maintaining vigorous growth and good garden performance, resolving the contradiction between early flowering and overall reliability.
