Solution Overview

Problem

There is a need for a cultivar of Acer truncatum that exhibits superior foliage quality, form, and fall color, which existing varieties have not adequately addressed.

Innovation Solution

Acer truncatum 'JFS-KW187' is developed through selection and asexual propagation, showcasing a unique combination of compact growth, dense branching, narrow upright growth habit, glossy foliage, and bright fall color, fixed in successive generations through budding on Acer platanoides rootstock.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional Acer truncatum varieties are used, then general growth is achieved, but foliage quality, form, and fall color are insufficient

Engineering Contradiction:

Improvefoliage qualityVSAvoidform and fall color

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the selection process into multiple generations (P1, P2, P3, P4, P5) with specific selection criteria applied at each stage. This systematic segmentation allows for progressive improvement of foliage quality, form, and fall color through repeated selection of superior individuals, ultimately producing the fixed cultivar 'JFS-KW187' with reliable superior characteristics.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies parameter changes by selecting and propagating trees with specific desirable parameters (compact growth habit, dense branching, glossy foliage, bright fall color). Through asexual propagation by budding, these parameter combinations are fixed and stabilized in the cultivar, ensuring consistent expression of superior foliage quality, form, and fall color across generations.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If selection and propagation process is extended over many years, then superior characteristics are achieved, but time consumption increases

Engineering Contradiction:

Improvesuperior characteristicsVSAvoiddevelopment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action through a systematic multi-generation selection program that identifies and propagates superior individuals at each stage (P1 through P5). By performing selection and asexual propagation in advance across multiple generations, the cultivar's superior characteristics are established and fixed before commercial introduction, reducing the time needed for later validation and deployment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses asexual propagation by budding to create exact genetic copies of superior selected trees. This copying mechanism allows the superior characteristics identified through years of selection to be replicated efficiently across multiple individuals without genetic variation, accelerating the establishment of the cultivar while maintaining consistent superior traits.

Inventive Principle:

Principle #26Copying
