Solution Overview

Problem

There is a need for a new rose cultivar that combines desirable traits such as deep pink flower color, strong fragrance, upright growth habit, and improved flowering characteristics, while maintaining stability through successive propagations and offering resistance to certain diseases and environmental conditions.

Innovation Solution

The development of the rose cultivar 'RNF Pink 01', resulting from a breeding program between 'Bridal Pink' and an unnamed Rosa rugosa variety, which exhibits deeper pink flowers, fewer thorns, more buds per stem, and a unique fragrance, along with an upright growth habit, distinguishing it from its parents and other rose varieties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a breeding program combines multiple rose varieties to achieve desired traits, then flower color depth, fragrance strength, and growth habit improve, but plant complexity and breeding time increase

Engineering Contradiction:

Improveflower color depth and fragrance consistencyVSAvoidbreeding program complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple rose varieties (Rosa L. 'Bridal Pink' and an unnamed Rosa rugosa variety) to merge desirable traits including deep pink flower color, strong fragrance, and upright growth habit into a single cultivar 'RNF Pink 01', resolving the contradiction by achieving reliable trait expression through controlled hybridization

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If a rose variety is selected for deep pink flower color and strong fragrance, then aesthetic quality improves, but disease resistance and environmental tolerance may be compromised

Engineering Contradiction:

Improveaesthetic quality consistencyVSAvoiddisease and environmental stress susceptibility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates a composite genetic structure by hybridizing two distinct rose varieties, combining the aesthetic qualities of Rosa L. 'Bridal Pink' (deep pink color, strong fragrance) with the hardiness and disease resistance characteristics of Rosa rugosa, thereby achieving both aesthetic reliability and environmental tolerance in the new cultivar

Inventive Principle:

Principle #40Composite materials

3Productivity

If a rose variety produces more buds per stem, then productivity increases, but flower size and individual bloom quality may decrease

Engineering Contradiction:

Improvenumber of buds per stemVSAvoidindividual flower quality uniformity

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent optimizes the balance between productivity and flower quality by controlling specific parameters including bud density (multiple buds per stem), flower size (8-10 cm diameter), and bloom timing (continuous flowering from spring to fall), achieving both high productivity and maintained flower quality through selective breeding

Inventive Principle:

Principle #35Parameter changes
