Fragrance Patch With Porous Carrier For Diaper Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Absorbent personal care articles, such as diapers, often release unpleasant odors due to increased airflow, which can lead to skin irritation and discomfort, and there is a need for controlled fragrance application for both odor masking and aromatherapy purposes.
Innovation Solution
A personal care article design featuring a patch with an odor control agent housed in a sealed cavity, positioned between encasing layers, where the outermost layer has high air permeability to facilitate odor release and diffusion, and an optional carrier to stabilize and release the agent, allowing for controlled odor masking and fragrance application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If breathable materials are used in the outer cover to promote airflow and reduce moisture, then skin health is improved, but odor release increases
Solution Approach 1:
An odor control agent is introduced as an intermediary substance between the absorbent core and the breathable outer cover. This agent captures and neutralizes odorous compounds generated within the article while allowing breathable materials to continue their moisture-wicking function, thus mediating between skin health requirements and odor control needs
Solution Approach 2:
The odor control functionality is applied locally at specific positions within the personal care article, such as adjacent to the absorbent core or at strategic locations on the inner surface of the outer cover. This localized application targets odor sources directly while maintaining overall breathability of the structure
2Object-generated harmful factors
If odor control agents are applied directly to mask odors, then odor release is reduced, but skin irritation from volatile materials increases
Solution Approach 1:
A carrier material serves as an intermediary between the odor control agent and the skin. The carrier absorbs and holds the odor control agent, controlling its release rate and preventing direct contact with skin, thus reducing irritation while maintaining odor control effectiveness
Solution Approach 2:
Porous carrier materials are used to house the odor control agent. These porous structures provide large surface area for agent distribution while allowing controlled diffusion of active ingredients. The porous structure acts as a buffer, releasing odor control agents gradually rather than all at once, reducing skin exposure to high concentrations of volatile materials
3Adaptability or versatility
If fragrance is applied for aromatherapy purposes, then user satisfaction is improved, but complexity of the fragrance delivery system increases
Solution Approach 1:
The odor control agent serves multiple functions simultaneously: it controls unpleasant odors, provides pleasant fragrance for aromatherapy, and can be integrated into the existing absorbent article structure. This multi-functionality reduces the need for separate dedicated fragrance delivery systems
Solution Approach 2:
The carrier material automatically releases fragrance compounds in response to environmental conditions such as body heat, moisture, or airflow. This self-regulating release mechanism eliminates the need for complex pumps, timers, or user-activated systems, providing aromatherapy functionality through passive, condition-responsive release
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 solution effectively reduces odor release while preventing skin contact with volatile materials, providing a comfortable and aromatic personal care experience by ensuring the odor control agents are released through a porous structure with high air permeability, thus minimizing skin irritation and enhancing user satisfaction.
Implementation Method 1
air and water vapor will pass through the outer cover
Implementation Method 2
promote airflow in and around an infant's skin and this exchange of air helps reduce the levels of moisture
Implementation Method 3
mechanisms for masking and/or absorbing odors emanating from within soiled personal care articles
Implementation Method 4
mechanisms for masking and/or absorbing odors emanating from within soiled personal care articles

AI summary
Personal care articles are provided having odor control patches thereon. The patches include a cavity that house one or more fragrant materials or odor absorbing materials. A portion of the patch is detachable in order to expose and release the odor control materials contained therein. The patches can be removably-attached to the personal care article thereby allowing the patch to be affixed to the personal care articles at the time of manufacture or by the consumer just prior to use. The personal care articles are provided with an air-permeable pocket to house the patch and cover odor absorbing materials when the cavity is exposed.
