Pulp Base Material With Modulated Scent Release Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance-release devices based on passive diffusion have a limited product life due to a finite fragrance supply and varying evaporation rates, leading to an initial strong fragrance release that decreases over time, and a need for modulated scent release to maintain consumer satisfaction.
Innovation Solution
An article comprising a pulp base material with fibers and formed pores, where a volatile composition with top and base note components is used, with porosity zones in the material to modulate the release rate of fragrance compounds, enhancing the release of base notes and tempering the release of top notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If passive diffusion is used for fragrance release, then the device structure is simple, but the fragrance release rate varies over time (strong initially, decreasing later) and the product life is limited
Solution Approach 1:
The pulp base material incorporates zones with different porosity levels (high porosity zones and low porosity zones) to create localized variations in fragrance release characteristics. High porosity zones enhance release of base notes while low porosity zones temper release of top notes, achieving modulated scent release over time without changing the overall device structure
Solution Approach 2:
The patent changes the physical parameter of porosity within the pulp base material to control fragrance release rates. By creating regions with different porosity values, the system modulates the release of different fragrance components (top notes vs. base notes) to extend product life while maintaining simple device structure
2Illumination intensity
If high volatility compounds (top notes) are used in fragrance composition, then the initial fragrance intensity is strong, but the evaporation rate is fast leading to rapid depletion
Solution Approach 1:
The pulp base material creates low porosity zones specifically configured to contain and slowly release top note components. These zones temper the rapid evaporation of high volatility compounds, reducing fragrance depletion rate while maintaining initial fragrance intensity through controlled release
3Duration of action of moving object
If low volatility compounds (base notes) are used in fragrance composition, then the evaporation rate is slow providing long-lasting scent, but the initial fragrance intensity is weak
Solution Approach 1:
The pulp base material incorporates high porosity zones that enhance the release rate of base note components. These zones increase the initial fragrance intensity of low volatility compounds while maintaining their slow evaporation characteristics, thus extending scent duration without sacrificing initial impact
4Duration of action of moving object
If the fragrance composition is changed to modulate release rate, then the release profile can be adjusted, but the fragrance character and identity change
Solution Approach 1:
The pulp base material is segmented into distinct porosity zones (high and low porosity regions) that selectively interact with different fragrance components. This physical segmentation allows independent control of release rates for top notes and base notes without altering the fragrance composition itself, preserving fragrance character while modulating release profile
Solution Approach 2:
The pulp base material acts as an intermediary between the fragrance composition and the environment. It modulates the release of fragrance compounds through its porous structure without changing the chemical composition of the fragrance, thus preserving fragrance character while controlling release profile over time
