Solution Overview

Problem

Existing fragrance compositions lack a high performing and high impact bloom fragrance accord that effectively enhances fragrance intensity and bloom speed in consumer products.

Innovation Solution

A fragrance accord comprising Class 1 ingredients with an experimental velocity of 8.5 cm/second or greater, Class 2 ingredients with a velocity of less than 8.5 cm/second and greater than 5 cm/second, and optionally Class 3 ingredients, designed to enhance fragrance diffusivity and intensity through specific physical properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional fragrance compositions are used, then fragrance coverage is provided, but fragrance intensity and bloom speed are insufficient

Engineering Contradiction:
Improvefragrance intensityVSAvoidbloom speed
Core Design Contradiction:
Illumination intensityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by selecting fragrance ingredients based on specific physical properties (molecular weight between 70-175 amu, C log P values between 0-4, boiling points between 100-300°C) to optimize both fragrance intensity and bloom speed. This systematic parameter selection resolves the contradiction by finding the optimal range for each property that simultaneously enhances intensity and accelerates bloom.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by formulating high impact accords that combine multiple fragrance ingredients with complementary properties. The accord includes ingredients with different volatility profiles and molecular characteristics that work together to provide both immediate bloom and sustained intensity, resolving the contradiction between speed and intensity.

Inventive Principle:
Principle #40Composite materials

2Speed

If fragrance ingredients with high volatility are used to improve bloom speed, then fragrance intensity decreases

Engineering Contradiction:
Improvebloom speedVSAvoidfragrance intensity
Core Design Contradiction:
SpeedVSIllumination intensity

Solution Approach 1:

The patent resolves this contradiction by changing the parameter selection criteria to include ingredients with moderate volatility (boiling points 100-300°C) rather than high volatility. The specific molecular weight range (70-175 amu) and C log P values (0-4) are selected to achieve optimal balance between bloom speed and fragrance intensity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by assigning different roles to different ingredients within the accord. Some ingredients are selected for faster bloom contribution while others are optimized for sustained intensity, with each ingredient's properties locally optimized for its specific function within the overall composition.

Inventive Principle:
Principle #3Local quality
