Solution Overview

Problem

Existing Myoporum laetum cultivars are susceptible to thrip infestations, which cause leaf deformities and affect plant health, lacking effective resistance mechanisms.

Innovation Solution

The 'CLEAN n GREEN' cultivar, discovered as a naturally occurring mutation, exhibits inherent resistance to thrip infestations and maintains this trait through asexual propagation, characterized by glossy foliage and robust growth habits, making it suitable for landscaping and hedging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional Myoporum laetum cultivars are used, then they can be grown as ornamental shrubs, but they are susceptible to thrip infestations causing leaf deformities

Engineering Contradiction:

Improveresistance to thrip infestationVSAvoidthrip attack symptoms

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by selecting and propagating a plant variant with altered genetic parameters that confer resistance to thrip infestation. The 'CLEAN n GREEN' cultivar exhibits different biological parameters compared to conventional Myoporum laetum, specifically showing resistance to thrip attack while maintaining ornamental characteristics. This natural mutation was identified and stabilized through asexual propagation to preserve the resistance trait.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If thrip-resistant mutation is selected, then resistance to thrips is achieved, but it requires identification among many susceptible plants

Engineering Contradiction:

Improvethrip resistance traitVSAvoididentification of resistant plant

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent utilizes visual color changes as an indicator of the resistant trait. The 'CLEAN n GREEN' cultivar displays distinctive glossy green foliage that remains healthy and free from thrip-induced deformities, contrasting with the damaged appearance of susceptible plants. This visual differentiation simplifies the detection and selection of resistant plants in the field.

Inventive Principle:

Principle #32Color changes

3Stability of the object's composition

If asexual propagation is used to maintain resistance trait, then true-to-type reproduction is achieved, but it requires established propagation protocols

Engineering Contradiction:

Improveconsistency of resistance traitVSAvoidpropagation process

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent employs asexual propagation methods to create exact genetic copies of the resistant 'CLEAN n GREEN' plant. Through techniques such as cutting and grafting, identical replicas of the resistant plant are produced, ensuring that the thrip-resistant trait is consistently transmitted to all propagated plants without genetic variation.

Inventive Principle:

Principle #26Copying
