Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic cat litter boxes face issues with bacterial growth and odor due to fermentation of contaminated litter, leading to contamination and poor user experience.
Innovation Solution
A vacuum packaging device with a shell, fixture, vacuum pumping mechanism, and heating element that vertically processes garbage bags, allowing them to be vacuum sealed and fused to isolate waste cat litter, preventing bacterial growth and odor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If waste cat litter is stored in a container for a period of time, then the storage function is achieved, but bacterial growth and fermentation occur leading to odor and contamination
Solution Approach 1:
The patent applies vacuum packaging to create a low-pressure environment inside the storage container, removing air and creating an inert atmosphere that prevents aerobic bacterial growth and fermentation. The vacuum state eliminates oxygen, thereby stopping the harmful biological processes that cause odor and contamination during storage.
Solution Approach 2:
The patent extracts air from the storage container through vacuum packaging, removing the harmful element (oxygen) that enables bacterial growth. By taking out the air, the system prevents the conditions necessary for fermentation and odor generation while maintaining the storage function.
2Object-affected harmful factors
If a vacuum packaging device is implemented, then bacterial growth and odor are prevented, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into an integrated vacuum packaging device that includes sealing, vacuuming, and storage capabilities in a single unit. This merging of functions reduces the need for separate components and simplifies the overall system architecture while maintaining the vacuum packaging functionality to prevent bacterial growth and odor.
Solution Approach 2:
The vacuum packaging device is designed to be self-contained, with the sealing structure and vacuum mechanism working together automatically. The device serves itself by creating the vacuum environment and maintaining it without requiring external intervention or complex control systems, thereby reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively isolates waste cat litter from the outside environment, preventing bacterial growth and fermentation, thus addressing contamination and odor issues.
Implementation Method 1
a vacuum pumping mechanism, which is located on the shell and can vacuum the garbage bag through the air hole
Implementation Method 2
a heating element, which is located in the fixture and used to locally fuse and maintain vacuum sealing after the garbage bag is vacuumized

AI summary
The present invention discloses a vacuum packaging device having a hollow area on the shell that allows garbage bags pass through vertically. The clamping portion of the fixture partially closes and clamps the garbage bag located in the hollow area through a closing action, and the poking portion on the inner side of the clamping portion pokes out an air hole in the locale; after the vacuum pumping mechanism vacuums the garbage bag containing waste cat litter through the air hole, so that the garbage bag containing waste cat litter is vacuum sealed and packaged. the present invention having a simple structure can automatically implement vacuum packaging to isolate waste cat litter from the outside and effectively address the pollution caused by bacterial growth and fermentation after long-term storage of waste cat litter.
