Biodegradable Litter Box with Perforated False Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cat litter systems are not environmentally friendly due to the non-biodegradability of litter materials and potential hazards from non-renewable sources and harmful ingredients, lacking a 100% biodegradable solution for litter disposal.
Innovation Solution
A biodegradable litter box system comprising a tray with a retractable lid, a perforated false bottom, and biodegradable accessories such as a scooper and disposable bags, allowing for complete disposal of soiled litter and waste as a single unit, ensuring environmental sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional non-biodegradable litter is used, then litter functionality is maintained, but environmental harm increases due to non-biodegradability and toxic ingredients
Solution Approach 1:
The patent changes the material parameters of litter from non-biodegradable clay or silica to biodegradable organic materials such as wood shavings, pine pellets, or paper-based litter. This parameter change maintains the litter's absorbency and clumping functionality while eliminating environmental harm and toxic ingredients, allowing the entire litter system to be composted safely.
Solution Approach 2:
The patent employs composite material structures in the litter box system, combining biodegradable plastic or natural materials for the box body with biodegradable litter materials. The box may incorporate multiple layers or composite structures that maintain durability during use while ensuring complete biodegradability after disposal, thus resolving the contradiction between functionality and environmental harm.
2Ease of operation
If disposable non-biodegradable litter boxes are used, then ease of disposal is improved, but environmental sustainability deteriorates
Solution Approach 1:
The patent applies the disposable principle by designing litter boxes intended for single-use or limited-use cycles. However, unlike traditional disposable boxes made of non-biodegradable plastic, these boxes are constructed from biodegradable materials that maintain ease of disposal while eliminating long-term environmental pollution. The boxes can be easily discarded in trash or composted after use.
Solution Approach 2:
The patent enables discarding and recovering by making the entire litter box system biodegradable. Instead of discarding persistent plastic waste, the used boxes and litter can be composted together, recovering nutrients back into the environment. This resolves the contradiction by making disposal both convenient and environmentally sustainable.
3Ease of manufacture
If traditional litter systems are used, then cost-effectiveness is maintained, but environmental safety is compromised
Solution Approach 1:
The patent changes the material composition parameters from inexpensive but toxic non-biodegradable materials to biodegradable organic materials. While the raw material cost may differ, the overall system becomes more cost-effective when considering waste disposal costs, environmental regulations, and safety concerns. The biodegradable litter and box materials eliminate toxic ingredients that harm pets and humans, resolving the safety compromise.
4Object-generated harmful factors
If biodegradable materials are used for the entire litter system, then environmental sustainability is improved, but product durability may worsen
Solution Approach 1:
The patent optimizes the physical and chemical parameters of biodegradable materials to achieve sufficient durability during the litter box's service life. By selecting appropriate biodegradable polymers, natural fibers, or composite biodegradable plastics, the box maintains structural integrity and strength during use while ensuring complete biodegradation after disposal. This parameter optimization resolves the contradiction between durability and environmental sustainability.
Solution Approach 2:
The patent employs composite material structures combining different biodegradable materials with complementary properties. For example, a biodegradable plastic matrix reinforced with natural fibers provides both the necessary mechanical strength for daily use and guaranteed biodegradability after disposal. This composite approach resolves the contradiction by achieving both durability during use and environmental sustainability after disposal.

AI summary
A biodegradable litter kit to be used for the collection and disposal of animal waste. The kit includes a litter box having a tray portion and a retractable lid. The tray has a bottom and at least one protruding side. The box includes a perforated false bottom positioned within the tray for holding a layer of fresh litter above the bottom of the tray. The perforated false bottom permits for the passage of soiled litter but prevents the passage of fresh litter to the bottom of the tray thus keeping a layer of fresh litter accessible for use by an animal.
