Solution Overview

Problem

Current solutions for improving skin circulation, elevating skin temperature, and alleviating shoulder stiffness or sensitivity to cold are not universally effective due to individual sensitivity and preference variations, necessitating a novel composition that can efficiently enhance skin blood circulation and temperature.

Innovation Solution

A composition containing Arabian jasmine (Jasmin sambac) extract and 3-methyloctano-4-lactone, which suppresses sympathetic nerves, promoting parasympathetic dominance, thereby expanding blood vessels, improving circulation, and increasing skin temperature, thus alleviating cold sensitivity and stiffness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional compounds and compositions (hyssop extract, cassis condensate, chamomile extract) are used to improve skin circulation and increase skin temperature, then some individuals may experience benefits, but results are insufficient and highly variable due to individual sensitivity and preference differences

Engineering Contradiction:
Improveeffectiveness of skin circulation improvementVSAvoidindividual sensitivity variation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the chemical parameters by selecting specific compounds (ylang-ylang oil components, eugenol, isoeugenol, safrole) with defined molecular structures and pharmacological properties. These compounds have consistent vasoactive effects that work across different individuals, reducing sensitivity variation while maintaining circulation improvement effectiveness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite material by combining multiple active compounds (ylang-ylang oil, eugenol, isoeugenol, safrole) in a formulated composition. This synergistic combination targets multiple pathways in blood vessel dilation and circulation improvement, providing reliable results across different individuals regardless of their sensitivity to single compounds.

Inventive Principle:
Principle #40Composite materials

2Temperature

If sympathetic nerve activity is suppressed to expand blood vessels and improve circulation, then skin temperature increases and circulation improves, but the mechanism requires precise neurophysiological modulation

Engineering Contradiction:
Improveskin temperatureVSAvoidneurophysiological regulation mechanism
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent uses aromatic compounds (ylang-ylang oil, eugenol, isoeugenol, safrole) as intermediaries that mediate between external application and sympathetic nerve suppression. These compounds act as chemical messengers that trigger parasympathetic dominance and blood vessel dilation without requiring direct neural control systems, simplifying the overall mechanism while achieving temperature elevation.

Inventive Principle:
Principle #24Intermediary (Mediator)
