Self Scooping Cat Litter Box with Integrated Carriage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated cat litter boxes are bulky, inconvenient, and space-consuming due to the placement of cleaning components, which limits litter space and requires complex maintenance, while also allowing litter tracking and odor spread.
Innovation Solution
A self-scooping cat litter box design with all cleaning components positioned on a single cleaning carriage at one end, featuring a rotatable grate, waste container, and motor mechanism, along with a ramp to catch litter on the cat's paws, and a removable tray for easy waste disposal, preserving litter space and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cleaning components are positioned throughout various locations of the box, then the litter box can perform self-cleaning function, but the litter space available to the cat is limited and the device becomes bulky
Solution Approach 1:
The patent combines all cleaning components (rake mechanism, motor, receptacle) into a single integrated carriage assembly positioned at one end of the litter box. This consolidation allows the self-cleaning function to be maintained while maximizing the litter space available to the cat, as the cleaning mechanism occupies minimal space compared to distributed components.
Solution Approach 2:
The cleaning mechanism is segmented into modular components (rake, motor housing, receptacle) that are integrated onto the carriage assembly. This segmentation allows for compact arrangement of functional elements while maintaining ease of cleaning operation, resolving the contradiction between functional completeness and space efficiency.
2Extent of automation
If cleaning components are positioned throughout various locations of the box, then the self-cleaning function is achieved, but the device becomes complex and requires extensive maintenance
Solution Approach 1:
By merging all cleaning components onto a single carriage assembly, the patent reduces the number of separate mechanical systems that require maintenance. The integrated design simplifies the overall system architecture while maintaining automated self-cleaning functionality, thereby reducing maintenance complexity.
Solution Approach 2:
The patent extracts the cleaning mechanism as a separate, removable carriage assembly that can be independently accessed and maintained. This extraction allows the cleaning components to be serviced without disassembling the entire litter box structure, significantly simplifying maintenance procedures while preserving automated operation.
3Productivity
If cleaning components are positioned throughout various locations of the box, then the self-cleaning function is achieved, but additional space is consumed that could be used for litter
Solution Approach 1:
The patent merges the rake mechanism, motor, and receptacle into a compact carriage assembly that performs all cleaning functions. This integration achieves self-cleaning efficiency while consuming minimal space within the litter box, thereby preserving maximum litter space for the cat.
Solution Approach 2:
The cleaning components are arranged in a compact, space-efficient configuration on the carriage assembly, utilizing vertical and lateral dimensions optimally. This dimensional arrangement allows the cleaning mechanism to be positioned at one end of the box, minimizing its footprint and maximizing the litter space available in the remaining area.

AI summary
An automated cat litter box comprising self-scooping mechanisms on a scooping carriage assembly at one end of a litter pan. The scooping carriage contains therein a waste drawer having a removable tray covered in lining. The tray travels with the carriage to the opposing end of the litter so that a grate can flip backwards to shovel collected waste into the waste drawer.
