Rotatable Arc Shell Litter Device for Clean Dirty Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current litter devices for pets lack comprehensive efficiency in automatically cleaning waste and distinguishing between clean and dirty litter, making them inefficient and inconvenient for pet owners.
Innovation Solution
A litter device featuring a rotatable shell with a concave groove and support arms, a collection container, and a filter element that separates clean and dirty litter through rotation, allowing for effective waste collection and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the shell is designed with a specific arc shape and rotation mechanism, then the separation of clean and dirty litter is improved, but the device complexity increases
Solution Approach 1:
The shell is designed to rotate around an axis relative to the support arm, transforming from a static structure to a dynamic one. This rotation enables the separation function without requiring complex mechanical mechanisms, as the motion itself facilitates the division between clean and dirty litter zones.
Solution Approach 2:
The chamber is divided into a storage space and a separation space by the baffle and filter element. This segmentation allows different functional zones within the chamber, enabling efficient separation of litter types while maintaining a relatively simple overall structure.
2Productivity
If the shell opening area ratio is optimized, then the pet access and waste collection efficiency is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The design specifies that the ratio between the opening area and the maximum area defined by the outer contour line should be greater than 0.9. This parameter optimization ensures efficient pet access and waste collection while providing a clear manufacturing guideline that balances precision requirements with functional performance.
3Manufacturing precision
If the baffle and filter element are extended beyond the shell inner wall, then the separation function is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The baffle and filter element are pre-configured to extend from the shell inner wall in a specific direction. This preliminary arrangement ensures that the separation function is automatically achieved during normal operation without requiring additional assembly steps or complex adjustment mechanisms.
