Solution Overview

Problem

Existing Hydrangea varieties lack improved green-like flower colors and vintage visual appearance, with limited heat and frost tolerance, and medium drought tolerance.

Innovation Solution

A new Hydrangea cultivar 'Strared' is developed through breeding, featuring deep red and green-colored flowers, strong stems, and enhanced temperature tolerance, resulting from a cross between Seedling 1012 and Seedling 08006-2, with asexual reproduction via stem cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If existing Hydrangea varieties are used, then they have basic flowering capability, but they lack improved green-like flower colors and vintage visual appearance

Engineering Contradiction:

Improveflower colorVSAvoidvisual appearance variety

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by developing a new cultivar with specific genetic traits that alter flower color parameters. The 'Strared' hydrangea exhibits deep red and green coloration through controlled breeding, changing the color parameters from conventional single-tone flowers to multi-tonal vintage appearance with specific hue, saturation, and brightness characteristics

Inventive Principle:

Principle #35Parameter changes

2Strength

If existing Hydrangea varieties are used, then they have basic stem strength, but they lack strong stems and improved temperature tolerance

Engineering Contradiction:

Improvestem strengthVSAvoidtemperature tolerance

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and breeding plants with enhanced structural parameters. The 'Strared' cultivar demonstrates improved stem strength through selective breeding for stronger vascular tissue and increased biomass allocation to structural support, while simultaneously enhancing temperature tolerance parameters through genetic selection for heat and frost resistance

Inventive Principle:

Principle #35Parameter changes

3Reliability

If existing Hydrangea varieties are used, then they have medium drought tolerance, but they lack enhanced overall hardiness and consistent characteristic retention

Engineering Contradiction:

Improvedrought toleranceVSAvoidcharacteristic retention

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies self-service through asexual reproduction via stem cuttings, where the plant propagates itself to produce genetically identical offspring. This self-propagation mechanism ensures that the distinctive characteristics of 'Strared' (deep red and green flower colors, strong stems, temperature tolerance) are automatically retained in subsequent generations without requiring external intervention or hybridization

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent applies parameter changes by establishing stable genetic parameters through asexual reproduction. The cultivar maintains consistent phenotypic parameters (flower color, stem strength, temperature tolerance) across generations by propagating from cuttings that preserve the exact genetic composition, ensuring reliability and true-to-type characteristics

Inventive Principle:

Principle #35Parameter changes
