Solution Overview

Problem

Chokecherry plants are limited as ornamental trees due to their invasive growth habit caused by dominant root suckering, which contrasts with desired characteristics like attractive foliage and wildlife habitat.

Innovation Solution

A new chokecherry tree variety 'P002S' with a complete absence of root suckering, strong upright, uniformly broad and oval single trunk form, large glossy leaves that mature into dark reddish-purple foliage, and strong hybrid vigor, achieved through selection and asexual propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional chokecherry plants are used, then attractive foliage and wildlife habitat qualities are provided, but invasive root suckering and multi-stem growth habit limit ornamental use

Engineering Contradiction:

Improveornamental useVSAvoidroot suckering

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts and eliminates the harmful suckering trait from the chokecherry plant through selective breeding. The selected plant 'P002S' naturally lacks the root suckering characteristic that plagues conventional chokecherry varieties, separating this harmful trait from the desirable ornamental qualities like burgundy foliage and wildlife habitat value.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the growth parameter from multi-stem with root suckers to single-trunk without suckers. This fundamental parameter change in growth habit transforms the plant from an invasive shrub-like form to a desirable ornamental tree form suitable for landscaping and urban environments.

Inventive Principle:

Principle #35Parameter changes

2Shape

If conventional chokecherry plants are used, then burgundy foliage and wildlife habitat qualities are provided, but multi-stem branching prevents single trunk tree form

Engineering Contradiction:

Improvesingle trunk tree formVSAvoidmulti-stem branching

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

Instead of pruning and training multi-stem chokecherry plants to achieve a single-trunk form (the conventional approach), the invention inverts the approach by selecting a plant that naturally develops a single-trunk form without requiring intervention. The 'P002S' variety inherently produces the desired upright single-trunk architecture.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention changes the structural parameter from multi-stem branching to single-trunk growth. This fundamental morphological parameter change creates a uniform, broad oval canopy supported by a single strong trunk, achieving the classic ornamental tree form.

Inventive Principle:

Principle #35Parameter changes
