Garbage Can Magnetic Seal Preventing Odor Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garbage cans with ultraviolet sterilization and automatic opening/closing mechanisms are insufficient in preventing odor leakage, especially when dealing with large amounts of garbage, as odors can still escape through gaps between the cover and inlet.
Innovation Solution
A garbage can design featuring airtight magnetic attachment between the cover and inlet, utilizing a pressurizing panel to open and close the cover with magnetic force, preventing odor leakage without additional user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If general packing is used to prevent odor leakage, then the structure is simple, but odor leakage prevention is insufficient
Solution Approach 1:
The patent replaces the traditional mechanical packing system with a magnetic field-based attachment system. Magnets embedded in the cover and corresponding magnetic elements in the inlet create an invisible magnetic field that holds the cover tightly sealed, eliminating the need for complex mechanical packing structures while achieving effective odor leakage prevention.
Solution Approach 2:
The patent changes the attachment parameter from mechanical friction (packing) to magnetic force. By embedding magnets in the cover and corresponding magnetic elements in the inlet, the system achieves a stronger and more reliable attachment force that effectively seals the opening without requiring complex mechanical packing structures.
2Object-affected harmful factors
If magnetic attachment is used to ensure tight seal, then odor leakage is prevented, but opening operation becomes difficult
Solution Approach 1:
The patent extracts the magnetic attachment function from the opening/closing mechanism. The magnetic field provides continuous sealing force when the cover is closed, but this force is naturally overcome when the user applies force to open the cover, allowing easy operation without compromising the seal during normal closed operation.
Solution Approach 2:
The magnetic attachment system transitions from a static mechanical connection to a dynamic magnetic field-based connection. The magnetic force continuously maintains the seal during closed operation, but can be easily overcome by user force when opening is required, providing both effective sealing and ease of operation.
3Object-affected harmful factors
If additional operations are added to open the magnetic cover, then sealing is maintained, but ease of operation is reduced
Solution Approach 1:
The magnetic cover system is designed to be self-opening. The magnetic attachment maintains sealing during normal operation, but when the user applies force to the cover, the magnetic force is naturally overcome and the cover opens automatically without requiring additional operations such as releasing a latch or pressing a button.
Solution Approach 2:
The patent separates the sealing function (provided by magnetic attachment during closed operation) from the opening operation. The magnetic field maintains the seal automatically, and the cover can be opened by simple user force without requiring additional operational steps, achieving both sealing maintenance and ease of operation.

AI summary
A garbage can provided with an airtight means for preventing odor leakage is provided. In the garbage can, garbage odors may be prevented from leaking into a gap between a cover for opening and closing an inlet for garbage of the garbage can in a casement method and an upper cap provided with the inlet for garbage formed thereon, and also the cover is automatically sealed and opened by the airtight means only by using a pressurizing panel used to open and close the cover without any additional operation, thereby providing convenience of use.
