Litter Box Cover with Inward Extending Bottom Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional animal litter boxes often experience excrement leakage through the entrance/exit, soiling the surrounding area when the animal discharges waste oriented towards the exit.
Innovation Solution
An animal litter box design featuring a cover part with extending bottom and side parts that guide the animal away from the walls, inclining inwardly to prevent excrement from leaking and providing a safe entry/exit path, with an oblique inclination and bent end to facilitate easy discharge and prevent accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover part has walls surrounding the peripheries excluding the entrance/exit, then the animal can safely discharge excrement without being alert, but excrement may leak from the entrance/exit and soil the surroundings
Solution Approach 1:
The extending bottom part projects inward from the lower end of the cutout, creating a three-dimensional barrier that extends into the litter box interior. This dimensional extension prevents excrement from reaching the cutout opening, solving the leakage problem while maintaining the enclosing wall structure for animal safety
Solution Approach 2:
The extending bottom part acts as an intermediary barrier between the animal's excretory area and the entrance/exit cutout. It intercepts excrement before it can reach the opening, preventing leakage while allowing the walls to continue providing a safe enclosed environment

AI summary
An animal litter box (1) includes: a main body part (10) that receives excrement of an animal; and a cover part (20) that is removably mounted to an upper portion of the main body part (10). The cover part (20) includes wall parts (21) on front-back-direction sides and on left-right-direction sides, and the cover part (20) has an open top at a ceiling. The cover part (20) has a cutout (25) in at least one location in the wall parts (21) provided on front-back-direction sides and on left-right-direction sides, and the cutout (25) serves as an entrance/exit when the animal enters or exits the animal litter box (1). The cover part (20) includes an extending bottom part (26) that extends inward with respect to the wall part (21), from a lower end portion (25eb) of the cutout (25).
