Microdosing Scent Dispenser for Nose-Targeted Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scent delivery systems are bulky and treat everyone in a room with fragrance, lacking precision and control in delivering scents or medical agents directly to an individual's nose.
Innovation Solution
A controllable fluid sample dispenser with a microdosing device and driver unit that delivers precise dosing of scents or medical agents directly to the nose, using a carrier gas to suspend particles and adjust dosing rates for individual exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If known scent delivery systems are used to provide intensive scent impression in rooms, then the scent delivery intensity is sufficient, but the systems are relatively bulky and treat every person in the room with fragrance
Solution Approach 1:
The invention divides the scent delivery system into a portable personal device that can be carried by individuals, separating the function of scent delivery from room-scale environmental control. This segmentation allows intensive scent delivery to be concentrated on the individual user rather than dispersed throughout a room, reducing the overall system size required while maintaining or enhancing scent intensity at the point of use.
2Adaptability or versatility
If known scent delivery systems are used to treat every person in a room with fragrance, then coverage is comprehensive, but precision and control in delivering scents directly to an individual's nose is lacking
Solution Approach 1:
The invention applies local quality by concentrating the scent delivery function at the precise location of the user's nose rather than distributing fragrance uniformly throughout a room. The portable device enables localized, targeted delivery with high dosing precision, allowing different scent concentrations and patterns to be applied to different individuals simultaneously, thereby achieving both adaptability and precision.
3Measurement precision
If microdosing device is used to deliver precise dosing directly to the nose, then dosing accuracy is high, but the device requires selective activation control
Solution Approach 1:
The invention employs dynamics by making the microdosing device selectively activatable and controllable, allowing it to transition between active and inactive states. This dynamic control mechanism enables the device to deliver precise doses only when needed, with the ability to adjust dosing patterns, timing, and intensity. The control system integrates sensors, processors, and actuators that work together to provide intelligent, adaptive dosing while maintaining high accuracy.
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
Enables precise and controlled delivery of small quantities of scents or medical agents directly to the nose, allowing for high dosing accuracy and adjustable timing, improving user acceptance and enabling new applications in gaming, diagnostics, and medical treatments.
Implementation Method 1
the microdosing device being configured to create, during an activation state, a flow of a carrier gas through the fluid sample reservoir for taking up particles of the fluid sample into the carrier gas
Data Source
AI summary
A fluid sample dispenser includes a microdosing device for outputting, during an activation state, a fluid sample at a fluid sample outlet to the environment, wherein the microdosing device is placeable adjacent to a person's nose so that a distance between the outlet of the microdosing device and a nostril of the person's nose is within a predefined range, and a microdosing driver unit for adjusting a dosing rate of the scent sample output at the scent sample outlet by selectively activating the microdosing device.
