Fragrance Capsule with Absorbent Medium for Sustained Scent Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance sampling devices, such as atomizers and peel-and-sniff cards, face limitations in providing a reliable and long-lasting sensory experience of fragrances, often resulting in incomplete or inaccurate scent representation and difficulty in distinguishing between multiple fragrances.
Innovation Solution
A fragrance delivery device comprising seamless, breakable capsules filled with a liquid core containing a fragrance compound and a non-glyceride solvent, surrounded by an absorbent medium and an outer paper covering that allows fragrance diffusion, along with a remote server system for information retrieval and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If fragrance is applied to traditional blotter paper, then the fragrance can be sampled, but the scent intensity decreases over time as the volatile fragrance slowly evaporates
Solution Approach 1:
The patent changes the physical state of fragrance delivery from liquid/absorbed form to encapsulated solid form. The capsule structure releases fragrance through controlled degradation, transforming the evaporation parameter into a sustained release mechanism that maintains scent intensity over extended periods.
Solution Approach 2:
The capsule acts as an intermediary between the fragrance compound and the user. Instead of direct contact with volatile fragrance on blotter paper, the capsule degrades slowly to release fragrance gradually, serving as a time-release mediator that sustains scent intensity.
2Reliability
If adhesives are used on peel-and-sniff cards to bond fragrance, then the fragrance can be delivered, but the adhesives interfere with the accurate reproduction of the true scent and may degrade over time
Solution Approach 1:
The patent extracts and eliminates the adhesive component entirely from the fragrance delivery system. By using a capsule structure that bonds fragrance to the card through physical encapsulation rather than chemical adhesion, the invention removes the source of scent distortion and degradation while maintaining fragrance delivery reliability.
3Adaptability or versatility
If multiple fragrances are sampled using traditional methods, then fragrance sampling is possible, but it is easy to forget which fragrance is applied to which blotter
Solution Approach 1:
The patent incorporates visual differentiation through color-coded or uniquely marked capsules for each fragrance type. This visual coding system allows users to quickly identify which capsule contains which fragrance, preventing confusion when sampling multiple scents while maintaining the versatility of the sampling system.
4Ease of operation
If atomizers spray fragrance into the air, then fragrance can be dispensed, but it is hard to get a good sample of the scent
Solution Approach 1:
The capsule structure serves as a controlled-release intermediary that dispenses fragrance through gradual degradation rather than instantaneous atomization. This provides a more precise and concentrated scent sample experience, allowing users to clearly perceive fragrance characteristics while maintaining ease of use through simple capsule breaking or dissolving actions.
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 device provides a long-lasting and faithful sensory experience of fragrances, with improved diffusion of top, middle, and bottom notes, and allows users to easily identify and review sampled fragrances through a connected system.
Implementation Method 1
The outer paper covering allows the fragrance compound to diffuse therethrough
Implementation Method 2
the adjacent absorbent medium absorbs the liquid core thereby gradually transporting the fragrance compounds toward the outer paper covering
Implementation Method 3
the shell is breakable having an initial crush strength (Ci) from 0.5 to 2.5 kg

AI summary
A fragrance delivery device and uses thereof are provided. The device includes a plurality of fragrance-loaded capsules; a biodegradable absorbent medium positioned adjacent the fragrance-loaded capsules along an axial direction in both directions; and an outer paper covering surrounding and containing the fragrance-loaded capsules and the biodegradable absorbent medium. Upon squeezing the capsule, the shell is ruptured releasing the liquid core, which is absorbed by the adjacent absorbent medium thereby gradually diffusing the fragrance compound toward the outer paper covering and then diffusing into the adjacent surroundings. The outer paper covering contains printed indicia including a two-dimensional barcode, which connects the user to a remote server. Upon detection, decoding, and/or transmission of the two dimensional bar code by a visual detection application residing on a portable electronic device to the remote server, information relating to the fragrance delivery device is transmitted to and displayed on the portable electronic device.
