Pet Waste Containment System with Sealed Bag Liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pet waste containment and disposal systems are ineffective in reducing odor release and preventing the spread of pathogens, as they often rely on open receptacles that attract scavengers and pose risks to sanitation personnel.
Innovation Solution
A pet waste containment and disposal system featuring a receptacle with a closed bottom and sidewalls, a cover assembly for sealing, and a partition assembly to separate waste into compartments, reducing odor release and facilitating sanitary storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open waste receptacles are used for pet waste disposal, then ease of operation is improved, but odor release and pathogen spread increase
Solution Approach 1:
The patent employs a flexible plastic bag liner that conforms to the receptacle shape, creating a barrier between the waste and the environment. This thin film enclosure contains odors and pathogens while maintaining ease of disposal through simple bag replacement rather than complex mechanical sealing systems.
Solution Approach 2:
The waste management system is segmented into removable components: the receptacle, the flexible bag liner, and the waste contents. This segmentation allows the bag to be easily removed and replaced without handling the receptacle itself, maintaining operational simplicity while achieving enclosed waste containment.
2Ease of operation
If open waste receptacles are used for pet waste disposal, then ease of operation is improved, but attraction of scavengers increases
Solution Approach 1:
The flexible plastic bag creates a complete enclosure around the waste, preventing scavengers from accessing the contents. The bag's flexibility allows it to conform to the receptacle shape while maintaining a sealed barrier that blocks insects, rodents, and other scavengers.
Solution Approach 2:
By separating the waste containment function into a removable bag component, the system eliminates the need for permanent structural enclosures that scavengers could exploit. The simple bag-and-receptacle segmentation maintains ease of use while providing effective scavenger protection.
3Device complexity
If conventional waste receptacles are used, then device complexity is reduced, but sanitation personnel exposure to pathogens increases
Solution Approach 1:
The flexible plastic bag liner acts as a disposable barrier that sanitation personnel never directly contact. The bag encapsulates all pathogenic materials, and personnel only handle the clean receptacle and sealed waste bags, dramatically reducing exposure risk without requiring complex sterilization or protective equipment systems.
Solution Approach 2:
The system uses disposable plastic bags that are discarded after a single use, eliminating the need for cleaning and sanitizing the receptacle between uses. This disposable approach protects sanitation personnel from pathogens while keeping the overall system simple and low-cost.
4Loss of time
If pet waste is disposed of in landfills without containment, then loss of time for waste collection is reduced, but pathogen spread throughout communities increases
Solution Approach 1:
The flexible bag provides a complete enclosure that prevents pathogen release during transport and landfill disposal. Waste can be quickly collected in the contained bag format without requiring complex containment structures, maintaining rapid collection while ensuring pathogens remain enclosed throughout the entire disposal process.
Solution Approach 2:
The waste is segmented into individually bagged units that can be quickly collected and transported. This segmentation allows for rapid waste removal while ensuring each pathogen-containing unit is independently enclosed, preventing spread even if one bag is compromised during handling or landfill processing.

AI summary
A pet waste containment and disposal system contains pet waste prior to collection, transport and proper disposal thereof and reduces release of pet waste odors therefrom. A pet waste receptacle assembly has a waste receptacle with an open top, a closed bottom and a sidewall which cooperatively define an internal volume thereof. A cover assembly includes a cover member having a closed top and an outer sidewall disposed therearound disposed into an overlying relation to the open top of the waste receptacle, defining a sealing orientation to reduce release of pet waste odors from the waste receptacle. A partition assembly having at least one partition member separating an internal volume of the waste receptacle into a plurality of waste compartments, wherein each of the plurality of waste compartments is dimensioned and configured to receive an amount of pet waste therein.
