Solution Overview

Problem

There is a need for a new and distinct Hydrangea cultivar that exhibits unique characteristics such as sturdy stems, compact growth, dense panicles, and interesting color-changing sepals, while also being comparable to existing cultivars in terms of disease resistance and cold tolerance.

Innovation Solution

The development of the Hydrangea paniculata cultivar 'LC NO25', which is characterized by sturdy stems, medium-sized compact plants, highly floriferous globular panicles, and sepals that change from green-white to dark pink, achieved through asexual reproduction by softwood cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the Hydrangea plant is bred for compact growth habit, then plant size is reduced and space efficiency is improved, but flowering display may be reduced

Engineering Contradiction:

Improveplant sizeVSAvoidflowering display

Core Design Contradiction:

Volume of moving objectVSQuantity of substance

Solution Approach 1:

The plant architecture is segmented into multiple tiers of branching, creating a compact structure with numerous flowering points distributed throughout the plant volume, allowing both compactness and abundant flowering

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cultivar exhibits nested branching patterns where multiple levels of branches are contained within a compact overall form, with panicles nested within the branching structure, achieving high flower density in a small volume

Inventive Principle:

Principle #7Nested doll (Nesting)

2Loss of time

If the Hydrangea plant is bred for early flowering, then time to market is reduced, but plant maturity and size may be compromised

Engineering Contradiction:

Improvetime to floweringVSAvoidplant maturity

Core Design Contradiction:

Loss of timeVSDuration of action of stationary object

Solution Approach 1:

The cultivar is propagated asexually from selected mother plants that had already achieved optimal flowering characteristics, ensuring that the new plants inherit pre-programmed early flowering genes and begin flowering sooner than sexually propagated varieties

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Through softwood cutting propagation, the exact genetic blueprint of the early-flowering parent plant is copied, preserving the early flowering trait while maintaining all other desirable characteristics of the mature parent plant

Inventive Principle:

Principle #26Copying

3Quantity of substance

If the Hydrangea plant is bred for dense panicles, then flowering density is improved, but weight and structural load on stems increase

Engineering Contradiction:

Improveflowering densityVSAvoidstem strength

Core Design Contradiction:

Quantity of substanceVSStrength

Solution Approach 1:

The heavy panicle mass is segmented into numerous small individual flowers distributed throughout a compact panicle structure, reducing the load concentration on any single stem point while maintaining overall flowering density

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cultivar exhibits localized reinforcement of stem tissue at critical attachment points where panicles connect to branches, providing targeted structural support where the load is greatest while keeping other parts of the stem lighter

Inventive Principle:

Principle #3Local quality

AI summary

A new and distinct cultivar of Hydrangea paniculata plant named ‘LC NO22’ is disclosed, characterized by sturdy stems on medium sized, compact plants. Plants are highly floriferous with globular panicles fully covering the plant. The sterile flowers have ornamental sepals that begin green-white, turn light pink and mature to dark pink. Foliage is distinctively healthy and strong. The new variety is a Hydrangea, typically produced as an outdoor ornamental plant.
