Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current rose cultivars lack a combination of mid-pink cupped blooms with a strong Old Rose/fruity fragrance and a medium-sized, bushy shrub growth habit capable of repeat flowering.

Innovation Solution

The development of a new Rosa hybrida shrub, 'AUSB18A15', which features sprays of cupped mid-pink blooms with a medium-strong Old Rose/fruity fragrance, and a medium-sized, bushy growth habit suitable for repeat flowering, achieved through asexual reproduction by budding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional rose cultivars are used, then they have various growth habits and bloom characteristics, but they lack the specific combination of mid-pink cupped blooms with strong Old Rose/fruity fragrance and medium-sized bushy shrub growth habit

Engineering Contradiction:

Improvecombination of bloom characteristics and growth habitVSAvoidcomplexity of achieving specific trait combination

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple desirable traits (mid-pink cupped blooms, strong Old Rose/fruity fragrance, medium-sized bushy shrub growth habit, repeat flowering capability) into a single unified cultivar through controlled cross-pollination and selection, creating a rose that integrates all these characteristics simultaneously rather than requiring separate cultivars for each trait

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If a rose is bred to have specific bloom characteristics, then it achieves desired flower traits, but the growth habit and flowering pattern may not be optimized

Engineering Contradiction:

Improveprecision of bloom characteristicsVSAvoidgrowth habit and flowering pattern

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The bred rose cultivar achieves multi-functionality by simultaneously expressing desirable traits across multiple dimensions: bloom appearance (mid-pink, cupped shape), fragrance (strong Old Rose/fruity), growth habit (medium-sized, bushy shrub), and flowering pattern (repeat flowering), making it suitable for diverse gardening applications

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If existing rose cultivars are propagated, then they maintain their established characteristics, but they cannot provide the new combination of traits desired

Engineering Contradiction:

Improveconsistency of characteristics through propagationVSAvoidavailability of new trait combinations

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent performs preliminary breeding actions through controlled cross-pollination between selected parent plants, followed by systematic evaluation of offspring, to pre-establish the desired trait combination before large-scale propagation, ensuring that the new cultivar reliably transmits all desirable characteristics through subsequent asexual propagation

Inventive Principle:

Principle #10Preliminary action
