Solution Overview

Problem

Current Hydrangea cultivars lack a compact variety with double flowers and distinct leaf color, failing to offer a unique combination of these traits in a stable and true-to-type propagation.

Innovation Solution

The development of the 'Strabru' cultivar, resulting from a breeding program, which exhibits double flowers and dark green leaf color, combining the compact nature and flower color traits from its parents, and retaining these characteristics through asexual propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional Hydrangea cultivars are used, then they have simple flower structure and common leaf color, but they lack double flowers and distinct leaf color characteristics

Engineering Contradiction:

Improveflower structure complexityVSAvoidtrait uniqueness

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crosses between selected parents, achieving the desired combination of double flowers and dark green leaf color in the 'Strabru' cultivar that distinguishes it from conventional varieties

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If new trait combinations are developed through breeding, then unique characteristics are achieved, but stability and true-to-type propagation may be compromised

Engineering Contradiction:

Improvetrait uniquenessVSAvoidpropagation stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The cultivar is propagated through cuttings rather than seed, using a reliable asexual propagation method that ensures genetic stability and true-to-type reproduction of the unique double flower and dark green leaf color traits

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Volume of moving object

If compact plant size is achieved, then space efficiency is improved, but flower display and leaf color visibility may be reduced

Engineering Contradiction:

Improveplant sizeVSAvoidflower and leaf visibility

Core Design Contradiction:

Volume of moving objectVSIllumination intensity

Solution Approach 1:

The compact 'Strabru' plant concentrates its visual appeal in specific local areas - the double flowers and dark green leaves are positioned to maximize visibility despite the small overall plant size, creating intense focal points of color and texture

Inventive Principle:

Principle #3Local quality
