Solution Overview

Problem

There is a need for a new Calibrachoa hybrida cultivar with distinct characteristics such as large lilac flowers, darker eye, green foliage, good branching, early flowering, and a moderately compact plant habit that is less sensitive to soil pH, which existing varieties do not adequately provide.

Innovation Solution

The development of the Calibrachoa hybrida cultivar 'CBRZ0020' through a planned breeding program, combining traits from parents 'CAL4132-18' and 'CASBO165-1', resulting in a plant with fixed characteristics retained through asexual reproduction, including semi-upright stems, compact growth, and continuous flowering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Calibrachoa varieties are used, then they have basic flowering characteristics, but they lack distinctiveness in flower color, plant habit, and environmental adaptability

Engineering Contradiction:

Improveadaptability to varying environmental conditionsVSAvoidconsistency of characteristics

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and breeding plants with specific phenotypic parameters (lilac flower color, compact growth habit, early flowering) to create a new cultivar with optimized characteristics that differ from existing varieties

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If existing Calibrachoa varieties are used, then they have established characteristics, but they show significant sensitivity to soil pH

Engineering Contradiction:

Improvesensitivity to soil pHVSAvoidadaptability to varying environmental conditions

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent converts the potential harm of soil pH variability into a benefit by selecting parent plants and progeny that demonstrate tolerance to pH variations, transforming an environmental stressor into a selection criterion for improved cultivar performance

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If existing Calibrachoa varieties are used, then they have moderate growth habits, but they lack early flowering and good branching characteristics

Engineering Contradiction:

Improveearly floweringVSAvoidplant structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by selecting parent plants with desirable traits (early flowering, good branching) and performing controlled hybridization in advance to produce F1 progeny that inherit these optimized characteristics

Inventive Principle:

Principle #10Preliminary action
