Cat Litter Waste Container Gate Mechanism for Odor Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste containers for pet waste are ineffective in containing odors, requiring frequent emptying due to strong odors emanating from pet waste, even when lids are closed, and often necessitate the use of expensive liners.
Innovation Solution
A waste container design featuring a base, intermediary part, gate, and lid mechanism that minimizes odor exposure by using a coupling member to control the gate's position, ensuring the lid and gate are closed simultaneously, with a sloped configuration to limit odor escape routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lid is used to contain odors when closed, then odor containment is improved, but user exposure to odor increases when the lid is opened to place waste
Solution Approach 1:
The waste container is divided into two functional sections: an outer container with a lid for general waste storage, and an inner container with a gate mechanism for controlled access. This segmentation allows the lid to remain closed for odor containment while the gate can be opened separately for waste placement, resolving the contradiction between odor containment and ease of operation.
Solution Approach 2:
The inner container with the gate mechanism acts as an intermediary between the user and the main waste storage area. The gate can be opened to place waste without opening the outer lid, serving as a mediator that allows waste placement while maintaining the closed state of the outer container for odor containment.
2Object-affected harmful factors
If waste is stored in individually wrapped packages with special liners, then odor containment is improved, but the cost of replacement liners increases
Solution Approach 1:
The invention replaces expensive special liners with a durable, reusable inner container that can be easily removed and cleaned. The inner container serves multiple uses over time, eliminating the need for continuous replacement of costly liners while maintaining effective odor containment through its sealed gate mechanism.
Solution Approach 2:
Instead of discarding expensive liners after single use, the inner container is designed to be recovered, cleaned, and reused multiple times. This recovery process eliminates ongoing costs associated with liner replacement while maintaining the container's hygiene and odor containment capabilities.
3Object-affected harmful factors
If the container is designed to minimize odor escape, then odor containment is improved, but the container must be emptied before full capacity to maintain effectiveness
Solution Approach 1:
The gate mechanism provides dynamic control over access to the waste storage area, allowing the container to remain effectively sealed regardless of fill level. The gate can be opened only when needed for waste placement and remains closed otherwise, maintaining odor containment effectiveness even when the container is full, thus maximizing utilization capacity.

AI summary
A waste container has a base providing a room for a liner to be put in to receive waste material, an intermediary part having an internal shell, and a lid mounted on top of one another. The waste container has a gate that controllably closes the internal shell, closing thereby the room. The waste container has a mechanism that comprises a member coupling the lid to the gate, thereby closing the gate when the lid opens. The mechanism comprises hooks holding the gate closed, and hook-release components coupled to the lid that, when closing the lid, release the gate from the closed position. Once released, the gate rotates downwards such 10 that waste material placed thereon falls into the room. Such a waste container minimizes the odors released from waste material in the room when collecting new waste material and placing it onto the gate.
