Solution Overview

Problem

Current l-menthol-based athletic performance enhancement products face challenges such as side effects from excessive menthol consumption, strong flavor profiles, and difficulty dissolving menthol crystals, particularly in hydration and nutritional products, necessitating the development of palatable, alcohol-free compositions that effectively induce a cooling sensation without compromising taste or safety.

Innovation Solution

Ingestible compositions containing l-menthol in amounts between 0.01-0.5 weight percent, combined with amino acids like branched-chain amino acids, dissolved in non-water solvents like medium-chain triglyceride oil, to provide a cooling sensation while maintaining palatability and avoiding side effects, and excluding alcohol.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If l-menthol is added to athletic performance enhancement products, then cooling sensation is improved, but side effects such as drowsiness, vertigo, nausea and vomiting increase

Engineering Contradiction:
Improvecooling sensationVSAvoidside effects
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by precisely controlling the concentration of l-menthol within the range of 0.01-0.5 weight percent. This quantitative adjustment optimizes the cooling sensation while staying below the threshold that triggers adverse effects such as drowsiness, vertigo, nausea and vomiting. The specific concentration range represents a critical parameter optimization that balances efficacy and safety.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements partial action by using a sub-maximal concentration of l-menthol (0.01-0.5 wt%) that provides sufficient cooling effect without reaching the excessive dosage level that causes harmful side effects. This partial application of menthol achieves the desired thermal sensation while avoiding the threshold for adverse reactions.

Inventive Principle:
Principle #16Partial or excessive action

2Temperature

If l-menthol is added to athletic performance enhancement products, then cooling sensation is improved, but the flavor profile becomes overwhelming

Engineering Contradiction:
Improvecooling sensationVSAvoidflavor profile
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by precisely controlling the concentration of l-menthol within the range of 0.01-0.5 weight percent. This quantitative adjustment optimizes the cooling sensation while staying below the threshold that overwhelms the overall taste of the product. The specific concentration range represents a critical parameter optimization that balances thermal effect and palatability.

Inventive Principle:
Principle #35Parameter changes

3Temperature

If l-menthol crystals are used in hydration and nutritional products, then cooling sensation is provided, but dissolution becomes difficult

Engineering Contradiction:
Improvecooling sensationVSAvoiddissolution
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by specifying a low concentration range (0.01-0.5 wt%) of l-menthol in the composition. This concentration parameter optimization improves dissolution characteristics while maintaining the desired cooling sensation. The reduced concentration facilitates better solubility and easier incorporation into hydration and nutritional products.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by incorporating l-menthol at varying concentrations within the 0.01-0.5 wt% range depending on the specific product formulation and desired effect. This localized optimization allows different product variants to have tailored menthol levels that balance dissolution ease with cooling efficacy for specific application contexts.

Inventive Principle:
Principle #3Local quality

4Ease of manufacture

If alcohol is used as a solvent for l-menthol, then dissolution is improved, but the product becomes unsuitable for hydration and nutritional use

Engineering Contradiction:
ImprovedissolutionVSAvoidproduct suitability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies the intermediary principle by using non-alcoholic solvents or vehicle systems to dissolve l-menthol. These intermediary substances facilitate the dissolution of menthol crystals while maintaining compatibility with hydration and nutritional product requirements. The intermediary solvent acts as a bridge between the poorly water-soluble menthol and the alcohol-free product matrix.

Inventive Principle:
Principle #24Intermediary (Mediator)
