Universal Ventilated Litter Box Assembly with Window Exhaust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for containing pet waste indoors, such as litter boxes, fail to effectively eliminate noxious smells from pet waste, as they either dilute odors in the living space or require complex installations that are not universally applicable.
Innovation Solution
A ventilated litter box system that uses an electrically powered fan to direct noxious odors from a pet waste receptacle through a flexible duct to a window vent panel, minimizing impact on window insulation and allowing for universal fitment in various home settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If hooded litter boxes are used to contain odors, then odor containment is improved, but cats refuse to use them because the stench becomes overpowering
Solution Approach 1:
The patent extracts the harmful odor from the enclosed space by introducing a ventilation system that actively removes odorous air through a fan and ductwork, separating the odor removal function from the containment structure. This allows the hood to maintain its containment shape while continuously extracting odors, preventing the buildup that would repel cats.
Solution Approach 2:
The patent employs pneumatic principles by using a fan-driven airflow system to actively transport odorous air from the litter box enclosure through ducts to an external exhaust location. This mechanical air movement replaces passive containment with active odor removal, maintaining a comfortable environment for cats while effectively managing odors.
2Object-affected harmful factors
If ventilated litter boxes are used to aerodynamically remove odors, then odor removal is improved, but they mix noxious odors with clean air in the living space by diluting them
Solution Approach 1:
The patent extracts odorous air directly from the enclosure and vents it externally, preventing the mixing of odorous and clean air within the living space. The exhaust opening is positioned to discharge odors away from the home, ensuring that clean indoor air is not contaminated by diluted odors.
3Object-affected harmful factors
If existing HVAC lines are accessed through wall holes, then odor venting is improved, but the installation becomes difficult to implement widely due to unique home arrangements
Solution Approach 1:
The patent creates a universal ventilation system that can be installed in various home configurations without requiring access to existing HVAC infrastructure. The flexible duct and adjustable exhaust components allow the system to adapt to different window positions and home layouts, making it universally applicable across diverse residential settings.
Solution Approach 2:
The patent incorporates dynamic, adjustable components including flexible ducting and repositionable exhaust openings that can be configured to match various home architectures. This flexibility allows the same basic system design to be adapted to different window locations and room layouts without requiring custom fabrication for each installation.
4Object-affected harmful factors
If window vent panels are used to direct odors outside, then odor removal is improved, but the window's insulating properties are compromised
Solution Approach 1:
The patent employs a flexible weatherproofing membrane or flange system that seals around the exhaust opening and duct connections at the window. This flexible sealing approach maintains the window's insulating properties by preventing air leakage around the vent components, while still allowing effective odor discharge to the exterior.

Function Achieved in This Case
Effectively removes unpleasant odors from pet waste receptacles by directing them outside the living space while maintaining window insulation and being adaptable to different window sizes and configurations.

Data Source
AI summary
The present disclosure is directed to devices and kits configured to displace noxious odors generated by pet waste or excrement from within pet waste receptacles, such as a litter box kept within the pet owner's living space or home to areas existing outside of such owner's living space via a preexisting window therein. More particularly, a flexible, elongated duct is coupled to an exhaust hole in any hooded litter box on one end, and on another end, coupled to an electrically powered fan and universal window vent panel. When the window vent panel is sealedly disposed in a window and the fan is powered on, noxious air within the receptacle is drawn through the exhaust opening in the enclosure, the duct, and an exhaust opening in the window vent panel to an outside of such window.
