Solution Overview

Problem

There is a need for new Cotoneaster varieties with novel plant habits for commercial ornamental purposes, as existing varieties do not offer the desired characteristics such as compact growth, formal shape retention, and specific leaf texture.

Innovation Solution

The development of the Cotoneaster hybrid cultivar 'MONSHGUS', which exhibits an upright and narrow growth habit, can be sheared into formal shapes, has small circular leaves with dense foliage, and is stable across multiple generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Cotoneaster varieties are developed with compact growth and formal shape retention, then adaptability to shearing and ornamental value are improved, but existing varieties lack the desired combination of characteristics

Engineering Contradiction:
Improveadaptability to shearingVSAvoidplant habit complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by selectively breeding for specific growth habit parameters (upright form, narrow width, dense branching) and leaf characteristics (small size, circular shape, glossy texture). This transforms the plant's physical parameters to achieve the desired compact, formal appearance that responds well to shearing while maintaining ornamental value.

Inventive Principle:
Principle #35Parameter changes

2Shape

If Cotoneaster varieties are developed with specific leaf texture and size, then ornamental characteristics are improved, but existing varieties do not offer the desired leaf properties

Engineering Contradiction:
Improveleaf shape and textureVSAvoidfoliage complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent applies local quality by focusing on specific leaf characteristics (small circular shape, glossy bright green color, fine texture) rather than overall plant structure. This targeted approach to foliage quality creates distinct ornamental value through localized leaf properties while maintaining a simple upright growth habit.

Inventive Principle:
Principle #3Local quality

AI summary

A new and distinct variety of Cotoneaster plant named ‘MONSHGUS’ is disclosed, characterized by a very narrow, upright plant form with dense growth. Plants of ‘MONSHGUS’ have been observed to have a mature size of 5 feet tall and 2 to 3 feet wide. The new variety is suitable for use as a hedge and can be sheared into formal shapes. The foliage is small and dense, creating a fine textured appearance. The new cultivar is a Cotoneaster, suitable for horticultural purposes.
