Pulp Sifting Trays for Odor Reduction in Modular Pet Litter Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet litter boxes, especially those made of plastic, face issues such as bacterial growth, odor retention, and difficulty in cleaning due to their impermeable nature, leading to health and behavioral problems for cats and environmental concerns from frequent replacements.
Innovation Solution
A modular pet litter box system utilizing pulp-based sifting trays with a base tray and high shield, designed for easy assembly and disassembly, which provides better airflow, reduces odor retention, and is environmentally friendly, with pulp material being more appealing to cats and easier to clean than traditional plastic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic litter boxes are used, then structural durability is improved, but bacterial growth and odor retention worsen due to impermeable surface
Solution Approach 1:
The patent applies porous materials by replacing traditional plastic litter box surfaces with materials that have controlled porosity, allowing air and moisture penetration. This enables the surface to remain durable while preventing bacterial growth and odor retention through improved airflow and drying capabilities, directly resolving the contradiction between structural durability and harmful factor reduction.
2Reliability
If plastic litter boxes are frequently replaced, then hygiene is improved, but environmental waste worsens
Solution Approach 1:
The patent applies parameter changes by modifying the material properties of litter boxes from conventional plastic to alternative materials with different degradation characteristics. These material parameter changes enable litter boxes to maintain hygiene over extended periods without requiring frequent replacement, thereby reducing plastic waste while preserving reliability.
3Ease of manufacture
If conventional plastic trays are used, then manufacturing cost is reduced, but cleaning difficulty and bacterial contamination worsen
Solution Approach 1:
The patent applies porous materials that inherently resist bacterial adhesion and allow for easier cleaning through their surface properties. While manufacturing costs may increase slightly compared to conventional plastic, the porous structure enables simpler maintenance and reduced cleaning difficulty, resolving the contradiction between manufacturing ease and operational ease.
4Loss of time
If litter boxes are not cleaned regularly, then time and effort are saved, but health and behavioral problems for cats worsen
Solution Approach 1:
The patent applies self-service principles by designing litter box materials and structures that naturally resist bacterial growth and odor accumulation, enabling the system to maintain hygiene without requiring frequent manual intervention. This self-maintaining property reduces cleaning time while preventing health and behavioral problems, resolving the contradiction between time savings and harmful factor prevention.

AI summary
A pet litter box system comprising a base tray with a non-apertured bottom wall and a plurality of sifting trays each with an apertured bottom wall, the sifting trays formed of molded pulp material. The sifting trays and base nest together. The system may include an upper shield seated on the nested sifting trays to contain litter that is kicked up by a cat utilizing the tray system. The shield may be formed of pulp and inverted to receive nested pulp sifting trays to define a transport or storage mode, the shield enhancing the combined structure in the transport or storage mode.
