Invertible-Lid Scent Dispenser for VOC-Free Dry-Air Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scent dispensers and odor absorbers require multi-component designs with fasteners and tools for assembly, often use volatile organic compounds (VOCs) as propellants, and are not portable or easily switchable between 'on' and 'off' configurations.
Innovation Solution
A scent dispenser/absorber apparatus using a cylindrical container, reversible lid, and scent cartridge that operates via 'dry air' diffusion without VOCs, allowing manual switching between 'on' and 'off' modes, and utilizing reticulated hydrophilic composite materials for scent release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-component designs with fasteners and tools are used for assembly, then device functionality can be achieved, but device complexity and ease of manufacture deteriorate
Solution Approach 1:
The patent integrates multiple functional components (scent cartridge, flow generator, housing) into a single unitary structure that can be produced as one piece or pre-assembled module, eliminating the need for separate fasteners and tools while maintaining all necessary functions
Solution Approach 2:
The simplified single-component design serves multiple functions simultaneously: containing the scent cartridge, generating airflow, and providing the dispensing structure, thereby achieving versatility without increasing assembly complexity
2Productivity
If VOCs are used as propellants for scent delivery, then scent dispersion efficiency is improved, but harmful factors and reliability deteriorate
Solution Approach 1:
The patent replaces harmful VOC propellants with a beneficial alternative: a flow generator that uses clean air or inert gas to deliver the scent, converting a potentially harmful delivery mechanism into a safe one while maintaining dispersion efficiency
Solution Approach 2:
The system uses an inert or clean atmosphere (non-VOC propellant) to carry the scent molecules from the cartridge through the dispensing mechanism, eliminating harmful emissions while preserving the ability to disperse scent effectively
3Ease of manufacture
If fixed configuration devices are used, then manufacturing simplicity is improved, but adaptability and ease of operation deteriorate
Solution Approach 1:
The patent incorporates a reversible lid that can be positioned in multiple configurations (on/off orientations), allowing the device to dynamically change its operational state without requiring multiple different device designs or complex adjustment mechanisms
Solution Approach 2:
The single reversible lid component performs multiple functions: it seals the container, controls scent release, and provides a manual switching mechanism between on and off states, thereby achieving configuration flexibility through a simple universal component
4Productivity
If liquid or aerosol propellants are used for scent delivery, then scent delivery effectiveness is improved, but harmful factors and reliability deteriorate
Solution Approach 1:
The patent converts the harmful liquid/aerosol delivery mechanism into a beneficial dry air diffusion system, where scent molecules are carried by clean air molecules rather than liquid droplets or aerosols, eliminating disease transmission risks while maintaining delivery effectiveness
Solution Approach 2:
The system replaces the mechanical liquid/aerosol propellant system with a molecular diffusion system where scent molecules are transported by ambient air molecules through diffusion, eliminating the need for liquid or aerosol carriers and their associated health risks
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 apparatus efficiently disperses or absorbs scents without liquids or aerosols, minimizing adulteration, and is portable, adaptable, and long-lasting, reducing the risk of disease spread and surface damage.
Implementation Method 1
embodiments of the present invention accomplish scent dispensing/absorbing functions with ambient air used as the propellant... operate via a diffusion process free of liquid droplets or aerosols

AI summary
A scent dispenser/absorber includes a container, an invertible lid reversibly attached to an open end of the container, a vented cage, and a scent cartridge housed within the cage. In an “off”' condition or state, the scent cartridge/cage combination is received in an interior chamber of the container, where the scent cartridge is out of communication with the surrounding environment and therefore incapable of performing scent dispensing function. The scent dispenser/absorber can be switched to an “on” condition or state by manually inverting the lid and, in some cases, the associated cage/scent cartridge combination, such that the scent cartridge can be positioned externally of the container, where it can communicate with the surrounding (i.e., external) environment to perform methods useful for attracting game, calming pets, medical diagnostics, aroma and insomnia therapy, and dieting.
