Scent Intensity Regulating Composition for Consistent Scent Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air freshening products experience inconsistent scent intensity due to varying evaporation rates of volatile compounds, leading to overpowering initial scent and reduced effectiveness over time, exacerbated by the first interaction with an interior space, which can create an unfavorable impression.
Innovation Solution
A scent intensity regulating composition comprising three components with specific vapor pressures and odor detection thresholds, designed to regulate the evaporation rate of volatile compounds, ensuring consistent scent delivery and reducing initial overpowering intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If highly volatile compounds are used in the volatile composition, then the initial scent intensity is high, but the evaporation rate becomes inconsistent over product life
Solution Approach 1:
The patent applies parameter changes by introducing a scent intensity regulating composition with specific vapor pressure characteristics (greater than 0.3 Torr at 25°C) and odor detection threshold (>20 ppb) to modify the evaporation parameters of the volatile composition. This regulates the evaporation rate to maintain consistent scent intensity throughout product life while preserving the beneficial highly volatile compounds.
2Illumination intensity
If carriers are added to slow down evaporation rate, then the initial overpowering scent is reduced, but the perfume raw material level is significantly reduced and scent character is altered
Solution Approach 1:
The patent uses an intermediary substance - the scent intensity regulating composition - that acts as a mediator between the highly volatile compounds and the environment. This intermediary regulates evaporation through its specific vapor pressure and odor detection threshold properties without significantly reducing perfume raw material levels or altering the fundamental scent character of the composition.
3Productivity
If the evaporation rate is high at the beginning, then the First Touch Point scent delivery is strong, but it creates an unfavorable first impression and reduces product effectiveness perception
Solution Approach 1:
The patent applies preliminary action by incorporating the scent intensity regulating composition into the volatile formulation before use. This pre-regulated composition ensures that from the very first application (First Touch Point), the scent is delivered at an optimal intensity level that creates a favorable first impression while maintaining effectiveness, preventing the initial overpowering effect that leads to unfavorable perceptions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves a controlled release of scent benefits, maintaining consistent scent intensity throughout the product life and improving the first impression in interior spaces without altering the formulation or scent character.
