Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current peppermint varieties are susceptible to mint wilt and mint rust diseases, and they do not offer a distinct essential oil composition compared to commercial standards.

Innovation Solution

Development of the 'Pendleton' mint variety, which is resistant to mint wilt and mint rust, and possesses a unique essential oil composition differing from commercial varieties through asexual propagation techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current commercial peppermint varieties are used, then they provide standard peppermint oil composition, but they are susceptible to mint wilt and mint rust diseases

Engineering Contradiction:

Improvedisease resistanceVSAvoidsusceptibility to mint wilt and mint rust

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by developing a new mint variety with altered genetic parameters that confer resistance to mint wilt and mint rust diseases. The 'Pendleton' variety represents a change in the biological parameters of the mint plant, specifically in its disease resistance traits, while maintaining productive oil yield. This resolves the contradiction by changing the variety parameter to achieve both disease resistance and economic viability.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If new mint varieties with distinct essential oil composition are developed, then they offer improved organoleptic properties, but they may differ from commercial oil standards

Engineering Contradiction:

Improveessential oil composition variabilityVSAvoidconsistency with commercial oil standards

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating a mint variety with distinct local characteristics in its essential oil composition. The 'Pendleton' variety has specific organoleptic properties and chemical composition that differ from commercial standards, offering improved sensory qualities. This resolves the contradiction by allowing local variation in oil composition while maintaining the plant's overall stability and productivity.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If asexual propagation is used to maintain genetic integrity, then the cultivar's genotype comes true to form, but propagation capacity must be sufficient

Engineering Contradiction:

Improvegenetic integrityVSAvoidpropagation capacity

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent applies self-service by developing a mint variety that produces its own propagation material through stolon formation. The 'Pendleton' variety naturally generates stolons that can be used for asexual propagation, eliminating the need for external propagation systems. This resolves the contradiction by enabling the plant to self-propagate while maintaining genetic integrity through clonal reproduction.

Inventive Principle:

Principle #25Self-service
