Litter Box Odor Extraction With Pet-Presence Fan Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deodorant devices for pet litter boxes are large, inflexible, and pose health risks, cause noise and vibrations, and increase the risk of litter box rejection by pets due to unpleasant odors and electrostatic discharge.
Innovation Solution
A compact, flexible deodorant device with a suction fan, presence sensor, and control unit that activates the fan only when the pet is not present, using activated carbon and magnetic fixing for adaptability, ensuring odor elimination and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ozone deodorant devices are used to eliminate odors, then odor elimination effectiveness is improved, but health safety deteriorates due to harm to human and pet health
Solution Approach 1:
The patent converts the harmful ozone generation process into a beneficial adsorption process using activated carbon. Instead of chemically reacting with odors (which produces harmful ozone), the activated carbon physically adsorbs odor molecules, transforming a potentially harmful chemical process into a safe physical process that eliminates odors without health risks.
Solution Approach 2:
The patent employs activated carbon as a consumable odor-absorbing material that can be replaced periodically. This disposable approach allows continuous effective odor elimination without the need for complex ongoing safety monitoring systems required by ozone generation devices, maintaining both effectiveness and safety.
2Productivity
If air ionisation deodorant devices are used, then odor elimination is improved, but safety deteriorates due to electrostatic discharge frightening pets
Solution Approach 1:
The patent eliminates the harmful electrostatic discharge effect by replacing the ionization process with activated carbon adsorption. The activated carbon safely captures odor molecules through physical adsorption without generating electrostatic energy, thus converting a process that caused harm into one that is inherently safe for pets.
3Productivity
If activated carbon devices with large dimensions are used, then odor elimination is improved, but adaptability deteriorates due to limited spaces for pet movement
Solution Approach 1:
The patent divides the activated carbon odor elimination function into multiple small distributed units rather than one large device. These segmented units can be positioned throughout the litter box, providing effective odor elimination while occupying minimal space and adapting to various litter box conformations without restricting pet movement.
Solution Approach 2:
The patent transitions from a large horizontal footprint device to a compact vertical or multi-dimensional configuration. By utilizing vertical space and three-dimensional positioning within the litter box, the device achieves effective odor elimination without consuming valuable horizontal space needed for pet movement.
4Productivity
If activated carbon devices with large dimensions are used, then odor elimination is improved, but device complexity increases requiring fixation to upper walls
Solution Approach 1:
The patent segments the odor elimination system into small self-contained units that can be freely positioned within the litter box without requiring wall fixation. Each unit is independently functional, eliminating the need for complex installation structures and simplifying both installation and maintenance.
5Productivity
If air movement devices are used to mix air, then odor elimination is improved, but noise and vibrations increase disturbing pets
Solution Approach 1:
The patent eliminates the harmful noise and vibration effects by replacing the mechanical air movement process with passive activated carbon adsorption. Odor elimination is achieved through the chemical adsorption process rather than mechanical air mixing, converting a noisy mechanical process into a silent chemical process that does not disturb pets.
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 effectively eliminates odors, reduces noise and vibrations, and minimizes litter box rejection by pets, providing high safety and operational flexibility.
Implementation Method 1
a suction fan (7) at least partially housed inside the suction body (2) and operatively associated to the suction body (2) to suck the airflow to be processed (F1) from the pet litter box and emit the processed airflow (F2) inside the pet litter box
Implementation Method 2
Some alternative solutions may involve the use of activated carbon through which the air is made to flow to eliminate the odors contained therein

AI summary
A deodorant device for a pet litter box comprises a suction body, having at least one inlet opening and at least one outlet opening, an odor eliminating device, activatable on a first airflow to be processed to eliminate an odor present therein, generating a processed second airflow, further comprising a suction fan, configured to draw in the first airflow to be processed from the pet litter box through the inlet opening and emit the processed second airflow through the outlet opening. Furthermore, the deodorant device comprises a control unit operatively associated with a presence sensor and configured to activate the suction fan as a function of the presence signal, particularly after the pet has come out of the pet litter box, and to deactivate the suction fan as a function of a presence signal from the presence sensor to prevent the operation of the suction fan while a pet is present inside the pet litter box.
