Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic packaging mechanisms for waterless toilets have complex structures, high costs, and suffer from sealing defects and inefficient space utilization due to air-filled garbage bags.
Innovation Solution
An automatic packaging mechanism with a hot melting assembly, gathering assembly, and buffer assembly that integrates a buffer assembly with an elastic member to ensure even heating and prevent sticking, along with a rotary base for orientation adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two sealing devices and a heating element are used for packaging, then the garbage bag can be sealed and cut off, but the structure becomes complex and packaging cost increases
Solution Approach 1:
The patent combines the sealing and cutting functions into a single integrated heating element. The heating element serves dual purposes: sealing the garbage bag by melting the material and cutting it off by creating a separation point. This eliminates the need for separate sealing devices and reduces structural complexity while maintaining packaging reliability
Solution Approach 2:
The heating element is designed to perform multiple functions within the packaging mechanism. It acts as both a sealing tool and a cutting tool, and also serves as a heating source for the entire packaging process. This multi-functionality reduces the number of components needed and simplifies the overall device structure
2Reliability
If the garbage bag is sealed with air inside, then the packaging is complete, but the volume increases and space is wasted
Solution Approach 1:
The patent implements preliminary compression of the garbage bag before final sealing. The compression mechanism removes air from the bag and compresses the contents beforehand, so that when the bag is sealed, it already has reduced volume. This preliminary action prevents air entrapment and ensures compact packaging from the start
3Productivity
If the garbage bag is heat-sealed directly without buffering, then the sealing process is fast, but the bag sticks to the heating element causing sealing defects
Solution Approach 1:
The patent introduces a buffer assembly as an intermediary between the heating element and the garbage bag. This buffer assembly includes a buffer plate and elastic member that provide controlled buffering during the heat-sealing process. The buffer prevents direct sticking while maintaining sufficient contact pressure for reliable sealing, and includes anti-sticking measures to prevent adhesion issues

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism provides reliable, efficient, and cost-effective packaging with reduced volume and improved space utilization, while allowing easy orientation adjustment for user convenience.
Implementation Method 1
the heating structure is configured to seal an upper end of the garbage bag containing excrement and a lower end of a new garbage bag, and at the same time, cut the sealed garbage bags apart from each other through melting

AI summary
An automatic packaging mechanism and an intelligent waterless toilet are provided. The automatic packaging mechanism includes a hot melting assembly (1), a gathering assembly (2), and a buffer assembly (4). The hot melting assembly includes a hot melting base (11) and a heating structure. The heating structure is arranged on the hot melting base. The gathering assembly (2) includes a gathering base (21) and a pressing base (22). The pressing base is arranged on the gathering base. A garbage bag passage (3) is formed between the pressing base and the heating structure. A material strip of a garbage bag opened passes through the garbage bag passage.
