Fragrance Dispenser with Dye-Activated Status Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diffusion-driven fragrance delivery systems lack an indicator to confirm correct activation and usage status, making it difficult for users to determine if the system is functioning as intended or has been depleted.
Innovation Solution
A scent delivery system featuring a wick and a diffuser with an increased surface area, where a dye depot within the capillary flow path dissolves and colors the fragrance preparation, providing a visual indication of activation and usage through color changes along the diffuser and wick.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wick and container system is used for fragrance delivery, then the system can release fragrance through capillary action, but the user cannot tell whether the system is working correctly or has been used up
Solution Approach 1:
The patent applies color changes by incorporating a dye depot that releases dye into the fragrance preparation as it flows through the wick and diffuser. The color change from无色 to colored provides a visual indicator showing that the system has been activated and is functioning correctly, allowing users to detect usage status without additional electronic components.
2Productivity
If the diffuser surface area is increased, then fragrance release into the environment is enhanced, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the diffuser into multiple lamellae (slices or layers) that are arranged around the wick. This segmentation increases the total surface area available for fragrance release while maintaining a simple structural pattern that can be manufactured easily. The lamellae can be identical or different, providing flexibility in design without significantly increasing complexity.
Solution Approach 2:
The patent applies dimensionality change by transitioning from a single-point contact (wick) to a multi-point contact system (diffuser with multiple lamellae). The diffuser lamellae are arranged in a three-dimensional configuration around the wick, creating multiple release points that increase surface area in the radial dimension while keeping the overall structure simple and manufacturable.
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 system effectively increases fragrance release and provides a clear visual cue to users about activation and depletion, enhancing user experience and system reliability.
Implementation Method 1
the fragrance preparation is transported in the received state of the wick in the container by capillary action against the direction of gravity through the wick to the diffuser
Implementation Method 2
The dye in the depot is dissolved by the fragrance preparation as it flows through the depot, in particular due to capillary action, and is thus colored along the further diffusion path of the fragrance preparation through the wick and/or the diffuser with the dye carried along
Implementation Method 3
the transported fragrance is released to the environment, usually via evaporation

AI summary
The invention relates to a fragrance-dispensing system, comprising a wick, at least one diffuser, wherein the diffuser surface in contact with the ambient air is larger than the wick surface in contact with the ambient air, and further comprising a container for accommodating the wick, and a fragrant substance preparation, which is stored in the container. The fragrant substance preparation, when the wick is accommodated in the container, is transported through the wick to the diffuser against the force of gravity by means of capillary action. Within the capillary flow path of the fragrant substance preparation through the wick and/or diffuser, at least one repository is provided, through which the fragrant substance preparation can flow and which has at least one dye that can be dissolved by the fragrant substance preparation.
