Enclosed Litter Box with Self-Closing Doors and Recirculating Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional litter boxes often result in litter spillage and foul odors due to inadequate containment and ventilation, making them unsuitable for indoor use.
Innovation Solution
An enclosed litter box system with self-closing doors, a recirculating ventilation system, and a directional ramped pathway to dislodge debris, which reduces airflow and odor escape, and features a filter to purify air within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If an enclosed litter box with self-closing doors is used, then odor escape is reduced, but device complexity increases
Solution Approach 1:
The enclosure is divided into separate functional zones: a litter tray area, a pathway with openings, and distinct entry/exit doors. This segmentation allows each component to address specific problems independently while working together to reduce odor escape.
Solution Approach 2:
A recirculating ventilation system with filters acts as an intermediary between the enclosed litter box interior and the external environment. The system draws air through filters and circulates it back, mediating the exchange of air while blocking odors from escaping outward.
2Object-generated harmful factors
If a recirculating ventilation system with filters is added, then air purification is improved, but device complexity and energy consumption increase
Solution Approach 1:
The recirculating ventilation system operates continuously to maintain air quality. Air is constantly drawn through the filters and circulated back into the enclosure, ensuring continuous purification without requiring the system to be turned on and off.
Solution Approach 2:
The ventilation system is designed to automatically circulate air through the filters without requiring manual intervention. The self-closing doors and automated ventilation work together to maintain enclosure integrity and air quality autonomously.
3Object-generated harmful factors
If a directional ramped pathway with openings is included, then litter spillage is reduced, but device complexity increases
Solution Approach 1:
The pathway incorporates angled ramps rather than flat surfaces. The incline and decline ramps create a directional path that uses gravity and angular surfaces to dislodge litter from animal paws as they traverse the pathway.
Solution Approach 2:
The pathway openings and angled ramps convert the potentially harmful effect of animal movement into a beneficial litter removal mechanism. As animals walk along the angled pathway, their movement naturally dislodges litter that would otherwise be tracked outside the enclosure.
4Object-generated harmful factors
If self-closing one-way doors are used, then containment is improved, but ease of operation decreases
Solution Approach 1:
The doors are designed with dynamic characteristics that allow them to automatically open and close based on animal presence and movement. The one-way door mechanism uses the animal's entry motion to automatically open the door and then self-closes it afterward, adapting to animal behavior patterns.
Solution Approach 2:
The self-closing doors automatically perform their containment function without requiring owner intervention. The doors self-regulate based on animal movement, opening when needed and closing to maintain containment autonomously.
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 system effectively minimizes litter spillage and odor dispersal, making it more suitable for indoor use by containing waste and odors within the enclosure.
Implementation Method 1
a recirculation ventilation system that includes a fan to draw air from the interior of the housing through a filter and then circulate the filtered air back into the interior of the housing
Implementation Method 2
These filters can be configured to remove odors from the air
Implementation Method 3
one or more self-closing doors that an animal can use as an entrance or exit to the housing and impedes airflow between the interior and exterior of the housing
Implementation Method 4
a ramp pathway comprising a plurality of openings sized and shaped to permit debris to pass through, where the pathway is positioned over a bottom of the interior of the housing such that the debris falls into a litter tray area
