Solution Overview

Problem

There is a need for a new variety of cherry laurel plant (Prunus laurocerasus) that exhibits winter hardiness, healthy growth, and a compact bushy habit, which are not adequately met by existing varieties.

Innovation Solution

The 'Jong3' variety, developed through open-pollination and vegetatively propagated via softwood cuttings, demonstrates these characteristics, including high temperature tolerance and disease/pest resistance, with a broad upright growth habit and glossy foliage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing cherry laurel varieties are used, then general growth is achieved, but winter hardiness and compact bushy habit are not adequately met

Engineering Contradiction:

Improvewinter hardinessVSAvoidsuitability for temperate climates

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by selecting and propagating a plant variant with specific genetic parameters that confer winter hardiness and compact growth habit. The open-pollination breeding process selected individuals with desirable parameter combinations (hardiness, compactness, glossy foliage) that differ from existing varieties, creating a new variety adapted to temperate climates with reliable winter survival.

Engineering Contradiction:

Improvecompact bushy habitVSAvoidgrowth rate

Core Design Contradiction:

ShapeVSProductivity

Solution Approach 1:

The patent applies local quality by developing a variety with specific localized characteristics - compact and bushy growth habit combined with glossy foliage - while maintaining overall healthy growth. The selection process identified plants with desirable local traits (compact branching structure, glossy leaf surface) that distinguish it from existing varieties, achieving aesthetic quality without sacrificing overall productivity.
