Solution Overview

Problem

There is a lack of a Berberis thunbergii cultivar with unique red foliage that maintains color throughout the summer season and has a distinct columnar habit, suitable for both container and landscape use, which is stable across different environmental conditions.

Innovation Solution

The development of the 'ROSY ROCKET' cultivar, a hybrid of Berberis thunbergii 'Aurea' and 'Helmond Pillar', exhibiting red foliage and an upright columnar habit, achieved through cross-pollination and stabilized through vegetative cuttings, making it suitable for containers and landscapes, and hardy to USDA Zone 5.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cross-pollination between Berberis thunbergii 'Aurea' and 'Helmond Pillar' is conducted, then unique red foliage color and columnar habit are achieved, but stability across environmental conditions must be verified

Engineering Contradiction:

Improvecultivar developmentVSAvoidphenotypic stability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent uses vegetative cuttings to create genetic copies of the selected parent plant, ensuring that the red foliage color and columnar habit are reproduced true to type in successive generations, thereby achieving phenotypic stability without relying on sexual reproduction variability

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent monitors and controls environmental, climatic, and cultural parameters during propagation and growth to maintain consistent phenotypic expression of the red foliage and columnar habit while preventing unwanted variations in the cultivated cultivar

Inventive Principle:

Principle #35Parameter changes

2Volume of moving object

If the plant is grown as a dwarf shrub for container or landscape use, then space efficiency is improved, but hardiness requirements must be met

Engineering Contradiction:

Improveplant sizeVSAvoidhardiness

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent selects and propagates plants with specific genetic parameters that confer both dwarf growth habit and cold hardiness, achieving a balance between small size and durability in USDA Zone 5 conditions through controlled breeding and selection

Inventive Principle:

Principle #35Parameter changes

3Duration of action of stationary object

If red foliage color is maintained throughout the summer season, then aesthetic appeal is improved, but susceptibility to pests and diseases may increase

Engineering Contradiction:

Improvefoliage color durationVSAvoidpest and disease resistance

Core Design Contradiction:

Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent develops a cultivar with red foliage that maintains its color throughout the summer season while exhibiting resistance to pests and diseases, creating a durable ornamental plant that does not require protective measures to maintain its aesthetic qualities

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
