Solution Overview

Problem

The horticultural industry lacks compact and well-branched Buddleia davidii cultivars with unique flower and foliage colors, as existing varieties either have different growth habits or flower colors that do not meet specific ornamental needs.

Innovation Solution

A new Buddleia davidii cultivar, 'Conbud2080', was developed through controlled breeding, exhibiting purple-rose colored flowers, dark green foliage, and a moderately vigorous, compact growth habit, distinguishable from its parents and other commercial varieties, suitable for ornamental use in parks, gardens, and residential settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Buddleia varieties are used, then they have established growth habits and flower colors, but they lack compact growth habit and unique flower-foliage color combinations needed for specific ornamental applications

Engineering Contradiction:

Improveornamental suitabilityVSAvoidgrowth habit complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by selectively breeding for specific growth parameters (compact habit, branching density) and color parameters (flower hue, foliage shade) to create a cultivar that meets precise ornamental requirements while maintaining manageable growth characteristics

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new cultivars with unique characteristics are developed, then ornamental value is improved, but differentiation from parent varieties and commercial varieties must be maintained

Engineering Contradiction:

Improvecharacteristic stabilityVSAvoidcolor differentiation precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by emphasizing specific localized characteristics (flower color, foliage color, growth habit) that differentiate the new cultivar from parent varieties, ensuring each trait contributes to overall distinctiveness and ornamental value

Inventive Principle:

Principle #3Local quality

3Shape

If compact growth habit is achieved, then ornamental value for specific applications is improved, but comparison with existing varieties like 'Boscranz' shows need for further differentiation

Engineering Contradiction:

Improvegrowth habit compactnessVSAvoidvarietal distinction complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining multiple desirable traits (compact growth habit, purple-rose flower color, dark green foliage) into a single integrated cultivar, creating a composite phenotype that exceeds the ornamental value of individual parent varieties

Inventive Principle:

Principle #40Composite materials
