Multi-Population Microcapsule Fragrance Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer products often experience a decline in fragrance noticeability over time due to volatility and habituation, leading to a desire for technologies that enhance the persistence and perception of fragrances.
Innovation Solution
A consumer product composition featuring distinct populations of microcapsules with varying fracture strengths and perfume oil ratios, which release fragrance in multiple blooms, combating habituation by providing a sustained scent experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single fragrance is used in consumer products, then the product provides initial fragrance noticeability, but the fragrance noticeability declines over time due to volatility and habituation
Solution Approach 1:
The fragrance system is segmented into multiple distinct fragrance compositions (first fragrance composition and second fragrance composition), each encapsulated in separate microcapsules with different fracture strengths. This segmentation allows the fragrances to release at different rates, providing sustained noticeability over time as each composition becomes noticeable at different intervals, thereby resolving the contradiction between initial noticeability and long-term persistence.
Solution Approach 2:
The invention changes the parameters of the fragrance delivery system by varying the fracture strength of microcapsules and the composition of fragrance blends. By adjusting these parameters across multiple fragrance compositions, the system maintains noticeable fragrance levels throughout the product lifecycle, preventing the decline that occurs with single-fragrance systems.
2Duration of action of stationary object
If multiple populations of microcapsules with different fracture strengths are used, then multiple blooms of fragrance are achieved, but the device complexity increases
Solution Approach 1:
The invention manages complexity by systematically varying key parameters (fracture strength and fragrance composition) across microcapsule populations. Rather than introducing entirely different mechanisms, the solution changes existing parameters to achieve multiple fragrance blooms, providing extended duration while keeping the overall system architecture relatively simple and manufacturable.
