Solution Overview

Problem

There is a need for a distinct and stable ornamental shrub variety of Callistemon viminalis that combines a compact growth habit with prominent red coloration of emerging and immature foliage, which is not currently met by existing varieties.

Innovation Solution

The development of the 'KPS38' variety, characterized by a compact growth habit and prominent red color of emerging and immature foliage, achieved through open pollination and subsequent asexual propagation, which maintains its distinguishing characteristics across generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If open pollination and asexual propagation are used to develop Callistemon viminalis variety, then distinct and stable ornamental characteristics are achieved, but the process requires multiple generations and selection steps

Engineering Contradiction:

Improvestability of ornamental characteristicsVSAvoidtime for propagation and selection

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary selection of candidate plants based on desired characteristics (compact growth habit, red foliage color) before final propagation. This preliminary action identifies the most promising candidates early, reducing the time needed for subsequent generations of propagation while ensuring stable ornamental traits are captured before commercial release.

Inventive Principle:

Principle #10Preliminary action

2Shape

If selection for compact growth habit and red foliage color is performed, then distinctive ornamental features are achieved, but the selection process requires multiple generations of evaluation

Engineering Contradiction:

Improvecompact growth habitVSAvoidduration of selection process

Core Design Contradiction:

ShapeVSDuration of action of stationary object

Solution Approach 1:

The patent focuses selection on specific local qualities - particularly the red coloration of emerging and immature foliage and compact growth habit - rather than evaluating all possible characteristics. This targeted approach to local qualities accelerates the selection process by concentrating evaluation efforts on the most distinguishing and commercially valuable features.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If asexual propagation through softwood cuttings is used, then stable transmission of distinguishing characteristics is achieved, but propagation efficiency depends on cutting success rates

Engineering Contradiction:

Improvestability of distinguishing characteristicsVSAvoidpropagation efficiency

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent utilizes softwood cuttings that root without requiring rooting compounds or hormones, allowing the plant material to self-service its own propagation needs. This natural rooting capability simplifies the propagation process, reduces input requirements, and maintains high stability of distinguishing characteristics while improving overall propagation efficiency and productivity.

Inventive Principle:

Principle #25Self-service
